  • Value of cephalic part of lateral crus in functional rhinoplasty
    • Authors: Amir A. Sazgar; Amin Amali; Mina Najarzad Peyvasty
      Pages: 4053 - 4059
      Abstract: Abstract Reshaping of the nasal tip is the most difficult part of rhinoplasty. Over the years, there have been many advances in the field of rhinoplasty, including tip plasty. The goal of these continuous refinements in existing procedures has been to improve both aesthetic and functional outcomes. The cephalic part of the lateral crus of the lower lateral cartilage is what mainly contributes to nasal tip deformity. Various surgical techniques have been reported that used the cephalic part of lateral crus to refine the nasal tip and preserve alar integrity and nasal breathing function. In this review article, we have attempted to show the evolution of these methods while focusing on development of approaches that are basic for “modern rhinoplasty” and presenting our personal preferences. We have also endeavored to categorize these methods and clarify some misconceptions and inaccuracies in their descriptions.

  • Postoperative pain in patients undergoing a transcutaneous active bone
           conduction implant (Bonebridge)
    • Authors: Luis Lassaletta; Miryam Calvino; Mario Zernotti; Javier Gavilán
      Pages: 4103 - 4110
      Abstract: Abstract The objective of the study was to evaluate postoperative pain following a transcutaneous active conductive hearing implant. 27 patients undergoing Bonebridge (BB) bone conduction implantation were evaluated with two pain-related questionnaires. The Headache Impact Test (HIT-6) was used to measure the degree of disability including none or little impact (≤49), mild (50–55), moderate (56–59), and severe (≥60). The Brief Pain Inventory (BPI) was used to assess pain severity score and function interference (0 = no pain to 10 = worst pain); meaningful pain was considered to be ≥3. The impact of surgical factors on postoperative pain was analyzed. Postoperative BB pain results were compared with 11 Vibrant Soundbridge™ (VSB) and 103 cochlear implant (CI) users. The mean pre- and postoperative HIT-6 scores for BB implantation were 42.6 and 41.8, respectively and the mean preoperative BPI pain severity score changed from 0.6 to 0.9 postoperatively, whereas the preoperative interference score changed from 0.1 to 0.3. None of the mean postoperative values revealed significant pain. The retrosigmoid approach, the need for dural or sinus compression, and the use of bone conduction implant lifts had no significant impact on pain scores. The mean postoperative HIT-6 pain scores for patients with BB, VSB, and CI were 41.8, 46.4, and 42.8, respectively, with the differences not being significant. BB implantation causes no significant postoperative pain irrespective of sinus or dura compression. Pain scores were similar to those experienced by patients with other transcutaneous auditory implants such as middle ear or CIs.

      Abstract: Abstract The aim of this study was to evaluate the insertion results and placement of the new Advanced Bionics HiFocus Mid-Scala (HFms) electrode array, inserted through the round window membrane, in eight fresh human temporal bones using cone beam computed tomography (CBCT). Pre- and post-insertion CBCT scans were registered to create a 3D reconstruction of the cochlea with the array inserted. With an image fusion technique both the bony edges of the cochlea and the electrode array in situ could accurately be determined, thus enabling to identify the exact position of the electrode array within the scala tympani. Vertical and horizontal scalar location was measured at four points along the cochlea base at an angular insertion depth of 90°, 180° and 270° and at electrode 16, the most basal electrode. Smooth insertion through the round window membrane was possible in all temporal bones. The imaging results showed that there were no dislocations from the scala tympani into the scala vestibule. The HFms electrode was positioned in the middle of the scala along the whole electrode array in three out of the eight bones and in 62 % of the individual locations measured along the base of the cochlea. In only one cochlea a close proximity of the electrode with the basilar membrane was observed, indicating possible contact with the basilar membrane. The results and assessments presented in this study appear to be highly accurate. Although a further validation including histopathology is needed, the image fusion technique described in this study represents currently the most accurate method for intracochlear electrode assessment obtainable with CBCT.

  • Skin flap complications after cochlear implantations
    • Authors: Wojciech Gawęcki; Michał Karlik; Łukasz Borucki; Joanna Szyfter-Harris; Maciej Wróbel
      Pages: 4175 - 4183
      Abstract: Abstract The objective of the study was to analyse and present the surgical management strategy for major skin flap complications (MSFC) after cochlear implantations. Patients fitted with a titanium-silicone-coated implant of the same kind, operated on between 1994 and 2013 with a standardised procedure (1076 medical charts) were analysed. Analysis aimed to identify and study individuals with skin problems related to the cochlear implant treatment, i.e. requiring surgical treatment in hospital defined as MSFC and focused on incidence, risk factors and treatment of MSFC. MSFC were diagnosed in 1.76 % of patients: 2.06 % of children and 1.35 % of adults, 2.43 % after implantation with a long “C”-shaped incision and 1.28 % after short retroauricular incision. Registered risk factors included head trauma, acute otitis media, poor hygiene in children, and general comorbidities in adults. The primary intervention was dependent on skin complication severity and included revision surgery with wound closure over an implant (52.6 %) and revision surgery with explantation (47.4 %). Revision surgery without explantation was successful in 40 % and the most effective approach was debridement with a two-layer rotational flap. Explantation led to ultimate wound healing in all cases. Major skin flap complications after cochlear implantation are rare, but their treatment is complex and difficult. Revision surgery with resection of infected tissue, formation of a rotational two-layer flap preceded and supplemented by intensive targeted antibiotic therapy can be effective and should be the first treatment option. Spontaneous implant explantation, abscess formation or unsuccessful primary treatment necessitate implant removal as the ultimate solution.

  • Facial palsy following cochlear implantation
    • Authors: Farid Alzhrani; Thomas Lenarz; Magnus Teschner
      Pages: 4199 - 4207
      Abstract: Abstract Owing to its anatomical location, the facial nerve (FN) is at risk of damage during cochlear implantation, especially during posterior tympanotomy. The aim of this study was, therefore, to evaluate the risk of FN palsy following cochlear implantation surgery via mastoidectomy and posterior tympanotomy approach (facial recess). This is a retrospective study. The data bank of patients who received a cochlear implant between 2000 and 2012 was analyzed. 3403 surgeries were done during this period. Records of the patients who had suffered from FN palsy were evaluated and the type of FN palsy, the severity, time of onset, and need for revision surgery were recorded. 0.76 % (26/3403) of the patients had FN palsy and were, therefore, included in the study. 76.9 % (20/26) subjects were 18 years or older. 0.15 % (5 subjects) suffered from immediate FN palsy and 0.62 % (21 subjects) from delayed FN palsy. Intraoperative FN injury was documented in only three subjects of the immediate FN palsy group. In two subjects with immediate FN palsy, the FN was intraoperatively exposed but not injured, despite these individuals’ experiencing FN palsy. In 100 % of the immediate onset FN palsy group a part of the FN was exposed during surgery, whereas it was exposed only in 9.5 % of the delay onset FN palsy group. Although the FN was bone protected in 19 subjects, they had FN palsy. Most of the subjects presented House-Brackmann grade III or IV (69.2 %). All of the subjects were treated initially with a conservative therapy, only 42.3 % (11 subjects) underwent revision surgery. The recovery rate was 80.8 % (in immediate onset palsy 40 %, in delayed onset palsy 90.5 %). Cochlear implantation entails only a minimal risk of FN palsy and that FN palsy is chiefly a transient problem.

      Abstract: Abstract The objective of the study is to evaluate the long term results of ossiculoplasty using the clip titanium partial ossicular replacement prosthesis. This study retrospectively reviews the partial ossiculoplasty conducted using clip titanium partial ossicular replacement prosthesis at a tertiary referral center. Audiometric outcomes and intraoperative findings were postoperatively measured from revision surgery of 47 ears (20 women, 27 men, mean age 43 years) averaging 6.5 years. The overall air-bone gap decreased from 25.7 dB preoperatively to 16.8 dB 6.5 years postoperatively (p ≤ 0.001, η p 2  = 0.210). An air-bone gap of <20 dB was present in 28 % of ears preoperatively and increased to 72 % postoperatively. In revision (n = 30) and primary tympanoplasties (n = 17), the preoperative air-bone gaps were reduced from 28.9 and 20.1 to 18.7 dB (p ≤ 0.001, η p 2  = 0.240) and 13.2 dB (p = 0.033, η p 2  = 0.192), respectively. In canal wall down (n = 15) procedures and tympanoplasties with intact canal wall (n = 32), the mean air-bone gaps diminished from 28.9 to 18.1 dB (p = 0.02, η p 2  = 0.245) and 24.2 to 16.1 dB (p ≤ 0.001, η p 2  = 0.221), respectively. In our own revision tympanoplasties (n = 8) and second look operations (n = 6), we found that the prostheses were safe to remove without any deleterious effects. Two prostheses were dislocated from the stapes’ head due to recurrent cholesteatoma. Therefore, it can be concluded that ossiculoplasty using the clip partial ossicular replacement prosthesis allows for good and reliable long term hearing results. Also, the flexible strips reveal no adverse effects on the encompassed stapes’ head and do not complicate revision surgery.

      Abstract: Abstract Chlorophyll c2 extracted from Sargassum horneri improved allergic symptoms in an animal model of allergic rhinitis. In the present study, we explored the efficacy of chlorophyll c2 in patients with seasonal allergic rhinitis. This was a single-center, randomized, double-blind placebo-controlled trial. Sixty-six patients aged 20–43 years, each with a 2-year history of seasonal allergic rhinitis, were randomly assigned to receive either a single daily dose (0.7 mg) of chlorophyll c2 or placebo for 12 weeks. The use of medications including H1-antihistamines and topical nasal steroids was recorded by rescue medication scores (RMSs) noted after 4, 8, and 12 weeks of treatment. Disease-specific quality of life was measured using the Japan Rhinitis Quality of Life Questionnaire (JRQLQ) both before and after 4, 8, and 12 weeks of treatment. The RMS at 8 weeks was significantly better in the chlorophyll c2 than the placebo group (mean RMS difference = −3.09; 95 % confidence interval = −5.96 to −0.22); the mean RMS at 4 weeks was only slightly better in the chlorophyll c2 group. The JRQLQ scores did not differ significantly between the two groups. Chlorophyll c2 would have a potential to be an alternative treatment for allergic rhinitis.

  • Association between vascular supply, stage and tumour size of juvenile
           nasopharyngeal angiofibroma
    • Authors: Raghav Mehan; V. Rupa; Vijay Kumar Lukka; Munawar Ahmed; Vinu Moses; N. K. Shyam Kumar
      Pages: 4295 - 4303
      Abstract: Abstract Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular tumour seen in adolescent males. To study the vascular pattern of these tumours, we retrospectively reviewed the records of patients with JNA who underwent preoperative angiography. Most (82.2 %) of the 45 patients assessed were Radkowski stage III with a mean size of 5.29 cm. There was a significant association between tumour stage and size (p = 0.029). Ten different vessels were seen to supply these tumours. All tumours had primary supply from the distal third of the ipsilateral internal maxillary artery (IMA). Accessory vessel supply was chiefly from the Vidian branch of internal carotid artery (ICA) (55.6 %). Stage III tumours were supplied by a greater number of feeding vessels than earlier stage tumours (p < 0.01). Larger tumours were more likely to have ICA supply (p = 0.04). Bilateral supply was seen in 48.7 %. However, there was no predominance of bilateral over ipsilateral IMA supply even in advanced stage tumours. One patient in our series was found to have a caroticocavernous fistula. Residual or recurrent tumours were characterized by new vasculature (100 %) and greater accessory supply from the ipsilateral ICA (85.7 %). Our study highlights the fact that surgical planning cannot be dependent on staging alone and should include preoperative assessment of tumour vasculature by angiography.

  • Office-based endoscopic revision using a microdebrider for failed
           endoscopic dacryocystorhinostomy
    • Authors: Jongyeop Park; Hochang Kim
      Pages: 4329 - 4334
      Abstract: Abstract This article is to introduce office-based endoscopic revision surgery using a microdebrider for failed endoscopic dacryocystorhinostomy (EN-DCR). The authors conducted retrospective, non-comparative, interventional case series analysis of 27 eyes of 24 patients, treated by office-based revision EN-DCR using a microdebrider. After local anesthesia, anatomical failures (cicatrization, granuloma, synechia) after primary EN-DCR were treated with a microdebrider (Osseoduo 120, Bien-Air Surgery, Le Noirmont, Switzerland) in an office setting, and a bicanalicular silicone tube was placed. Anatomical improvement and functional relief of epiphora were evaluated at 6-months after revision. The causes of failed EN-DCR were rhinostomy site cicatrization (17/27, 63.0 %), granulomatous obstruction (7/27, 25.9 %) and synechial formation (3/27, 11.1 %). The anatomical success rate was 100 %, and 85.2 % cases achieved complete relief of epiphora. The surgery did not exceed 10 min in any case and no complications were observed. Office-based revision EN-DCR using a microdebrider provided prompt management of post-DCR epiphora. The portable nature and all-round ability of the microdebrider allowed office-based surgery, which offered advantage to work with the surgeon’s own well-trained office staff. Office-based revision EN-DCR can be both time- and money-saving, and might be regarded the treatment of choice for failed EN-DCR.

  • Medial sural artery perforator flap in head and neck reconstruction
    • Authors: Heval Selman Özkan; Saime İrkören; Osman Enver Aydın; Aylin Eryılmaz; Hüray Karaca
      Pages: 4431 - 4436
      Abstract: Abstract Medial sural artery perforator (MSAP) flap is a relatively new flap which is a modification of medial gastrocnemius myocutaneous flap. Both radial forearm flap and MSAP has common benefits, such as thinness, long pedicle and pliability; however, MSAP has lower donor site morbidity when compared with radial forearm flap. Because of this reason, the MSAP flap has gained popularity during the last decade. The objective of this study was to determine clinical application results of this flap in reconstruction of post-oncologic defects in the head and neck region. 11 patients operated for head and neck post oncologic defects and reconstructed with MSAP between June 2014 and Dec 2015 were included in the study. Age, gender, histopathology, area of reconstruction, flap size, number of perforators were reviewed. Postoperatively recipient and donor site complications, hospital stay and additional surgical procedures were also analyzed. We had seven uncomplicated cases; one total flap failure due to arterial problem, in three cases due fistula formation and local wound healing problems additional surgeries were performed. All venous anastomosis were performed with 9/0 sutures, nine arterial anastomosis were performed with 9/0 and two arterial anastomosis were performed with 10/0 nylon sutures. Medial sural artery perforator flap is a good alternative in head and neck reconstruction, with the advantages of thin and pliable skin, a reliable vascular pedicle, straightforward intramuscular dissection. But there are certain drawbacks like tedious pedicle and perforator dissection, small arterial pedicle size which complicates anastomosis and obscurities of anatomy. Surgical team must always be ready for a difficult micro anastomosis and an alternative flap choice must be prepared and counseled with the patient in case of inadequate perforators.

      Abstract: Abstract To provide retrospective, descriptive information on patients with cervical necrotizing fasciitis treated at a single center during the years 1998–2014, and to evaluate the outcome of a newly introduced treatment strategy. Retrospective analysis of clinical data obtained from medical records. Mortality, pre-morbidity, severity of illness, primary site of infection, type of bacteria, time parameters. The observed 3-month mortality was 6/59 (10 %). The most common initial foci of the infection were pharyngeal, dental or hypopharyngeal. The most common pathogen was Streptococcus milleri bacteria within the Streptococcus anginosus group (66 % of the cases). Using a combined treatment with early surgical debridement combined with hyperbaric oxygen treatment, it is possible to reduce the mortality rate among patients suffering from cervical necrotizing fasciitis, compared to the expected mortality rate and to previous historical reports. Data indicated that early onset of hyperbaric oxygen treatment may have a positive impact on survival rate, but no identifiable factor was found to prognosticate outcome.

      Abstract: Abstract The management of head and neck tumors is guided by its nature, location and extension. Despite CNB accuracy and efficiency being widely described in the literature, there are few studies that evaluate the diagnostic utility of the technique performed in an outpatient setting, in the diagnosis of head and neck tumors. The aim of this study is to present the experience, sensitivity, specificity and accuracy of the CNB performed in an outpatient setting, free handed, in an important oncology school-hospital. A total of 2007 patients with tumors in the head and neck treated for a period of 3 years were evaluated. A retrospective chart review was performed in 36 of these patients, who underwent core needle biopsy for diagnosis. All samples collected were subjected to histopathological analysis. Values of accuracy, sensitivity and specificity were 94, 92 and 100 %, respectively. In our service, held in an outpatient setting and without the aid of imaging tests, the core needle biopsy proved to be a test with high accuracy values, sensitivity and specificity, easy of application, low morbidity and high predictability, with great use in diagnosing tumors in head and neck.

  • Cranial tonsillotomy for peritonsillar abscess: what a relief!
    • Authors: Jochen P. Windfuhr; M. Nematian; S. Ziogou
      Pages: 4507 - 4513
      Abstract: Abstract Peritonsillar abscess (PTA) is a common infection of the oropharynx resulting in painful swallowing, sometimes associated with fever, trismus and a typical voice alteration. Several draining methods have been suggested, including needle aspiration (NA), incision and drainage (ID), or abscesstonsillectomy. However, a gold standard of surgical therapy still does not exist. The aim of this study was to evaluate the outcome in patients who had undergone ID supplemented by cranial tonsillotomy (IDTT) as first-line treatment. A retrospective chart review of all patients who had undergone IDTT at our department in 2015 was performed. Demographic data, clinical findings, pain intensity on a 10-point visual analog scale, operation time and routine bloods before and after IDTT were collected. In addition, a 10-point visual analog scale (VAS) was utilized to measure personal satisfaction 2 weeks and 2 months after surgery. A total of 104 procedures were performed in 65 male and 38 female patients (median age 35 years), including one patient with a contralateral PTA 2 weeks after IDTT. Three patients had experienced abscess formation after admittance for antibiotic treatment of acute tonsillitis. 57.7 % of all patients denied intake of antibiotic therapy in their history at initial presentation. Patients were hospitalized for 3 days (median). The median pain intensity (VAS) within the first three postoperative days was 2, 1 and 1, respectively. Two weeks and 2 months after surgery patients were highly satisfied with the procedure (median value 10). Bleeding complications did not occur. IDTT is a novel surgical concept and associated with great patient comfort. It is safe, easy to learn and associated with an early return to normal diet and physical activity. These findings are supported by a rapid normalization of white blood cell count and C-reactive protein. IDTT eliminates the necessity of painful re-draining of the wound cavity and is free of bleeding complications. In contrast to ID and NA, histological examination of tonsillar tissue is feasible to disclose a previously undetected malign disease. Further analysis is warranted to verify the success rate in the long-term.

  • Gender-specific risk factors in post-tonsillectomy hemorrhage
    • Authors: Annekatrin Coordes; Janina Soudry; Veit Maria Hofmann; Minoo Lenarz
      Pages: 4535 - 4541
      Abstract: Abstract There are gender-specific differences in the frequency and course of different diseases. Specifically, some studies have shown an increased risk of post-tonsillectomy hemorrhage (PTH). The aim of the study was to investigate gender-specific risk factors for hemorrhage after tonsillectomy (TE)/abscess-TE. We anonymously reviewed and recorded the relevant data of all patients (≥14 years) who underwent a TE/abscess-TE between 2011 and 2013 in the ENT Clinic of the Charité Universitätsmedizin Berlin, Campus Benjamin Franklin. A patient survey was used to complete missing data. We analyzed gender-specific risk factors for PTH. During the study period, 460 operations were performed and the data of 250 patients were analyzed (213 TE and 37 abscess-TE). The median patient age was 27 years (ranging from 14 to 83 years). The rate of primary PTH (<24 h after TE/abscess-TE) was 3 %, and the rate of secondary PTH (>24 h) was 23 %. A significantly higher PTH rate was associated with males (p = 0.037), which was still apparent in ages 21–30 after sub-classification. Multivariate analysis calculated diagnosis, regular alcohol consumption and administration of glucocorticoids to be independent risk factors associated with gender. In conclusion, the PTH rate is gender-specific, and male patients are at higher risk, especially in young adulthood. Therefore, doctors should advise male patients of the increased risk of bleeding and stress the importance of compliance. Also, close postoperative follow-up is desirable.

      Abstract: Abstract The endoscopic transnasal route for the surgical removal of tumors in the sellar region is frequently associated with nasal complications such as synechiae or impaired nasal breathing. In this study, we investigated the impact of septal splints on avoiding surgery-related co-morbidities. 49 patients in whom endoscopic transnasal, transsphenoidal surgery for sellar tumors was performed between 2012 and 2014 were studied. In 30 of these, nasal septal splints were applied at the end of surgery to both sides of the septum and left in situ for 10 days (group 1), 19 patients received no splints (group 2). A standardized postsurgical follow-up investigation with endoscopic nasal examination, rhinomanometry and olfactory testing was performed on average 2 months postoperatively. Patients’ subjective nose-related discomfort at follow-up was assessed descriptively using a set of standardized self-rating statements on nasal problems. Synechias occurred less likely with nasal septal splints (n = 15; 50 %) than without (n = 16; 84.2 %). Moreover, multiple synechiae were predominantly observed in the group without septal splints (n = 10 vs. n = 2). Rhinomanometry showed improved flow-V150-inspiration scores when splints were used (with significant differences between groups for the left nostril: p = 0.039 and p = 0.022, resp.). In accordance, impaired nasal breathing after surgery was reported more frequently by 76.9 % of patients without splints, but only 56 % of patients with splints. Our results provide support for the application of nasal septal splints when operating endoscopically on tumors in the sellar region to reduce postoperative synechias and to improve nasal breathing.

      Abstract: Abstract Life expectancy in Israel has risen by almost 6 years during the last 25 years, and the proportion of people 65 years of age or older is expected to reach 12 % of the total population by 2020. A substantial increase in the workload for Otolaryngologists and Head and Neck surgeons is anticipated. Our goal was to characterize the admissions of patients 80 years of age and older to the Department of Otolaryngology, Head and Neck Surgery in a tertiary medical center. The study group included all patients 80 years of age and older who were admitted to the Department of OTOHNS in our institute between 2009 and 2013. There were two control groups for comparison divided by age; one group 40–59 years old and the other group 60–79 years old. There were 385 admissions of 317 patients aged 80–103 years (4.2 % of overall admissions). Over the study period, admissions of patients over 80 years increased on average by 3 % per annum (p = 0.4), and those patients over 90 years old by 52 % per annum (p < 0.001). The most common indication was HN malignancy (28.8 %) followed by otologic disorders (22.0 %). Of the overall 158 operations conducted, 131 patients (82.9 %) underwent elective procedures (mainly oncology) and 27 patients (17.1 %) underwent emergent procedures. The distribution of the reasons for admission of the patients older than 80 years is surprisingly different from that of the “younger” patients. With life expectancy rising, our study predicts a workload increase mainly in the HN oncologic and otologic services.

  • Mandibular melanotic neuroectodermal tumor of infancy: a role for
           neoadjuvant chemotherapy
    • Authors: Christopher Maroun; Ibrahim Khalifeh; Elie Alam; Pierre Abi Akl; Raya Saab; Roger V. Moukarbel
      Pages: 4629 - 4635
      Abstract: Abstract Melanotic Neuroectodermal Tumor of Infancy (MNTI) is a rare, locally aggressive neoplasm with a predilection for the head and neck area, most commonly occurring in the maxilla. The vast majority of treatment modalities for all cases of MNTI to date have involved surgical intervention only, with just 9.6 % involving some sort of chemotherapy, radiotherapy, or a combination of the prior mentioned modalities. There is very limited information available regarding the use of neoadjuvant chemotherapy, due to its rare nature. In this report, a 4 month old girl presented to our clinic with a chief complaint of a large oral mass of about 2.5 months in duration. Intraoral examination showed an oral mass arising from the lingual aspect of inferior alveolar ridge with extensive mandibular invasion. The patient received three cycles of vincristine, Adriamycin, and cyclophosphamide as neodajuvant therapy. Upon completion, the tumor had decreased significantly in size. The patient was then scheduled for surgery and underwent surgical resection of the tumor. We were able to obtain adequate shrinkage of the tumor to allow better resectability, easier surgical access and a more minimally invasive approach with no lip split and a smaller neck incision. In conclusion, we have reported an extremely rare case of MNTI of the mandible that was successfully treated with neoadjuvant chemotherapy and surgical resection. This approach was advantageous to minimize the chance of recurrence and improve resectability in particularly large tumors, while maximizing functional outcomes and minimizing deformity.

      Abstract: Abstract Retrospective analysis on 312 patients, operated for thyroid nodules between 2014 and 2015, was conducted to evaluate the impact of frozen section analysis on the strategy of thyroid nodule surgery. One hundred and ninety-three patients were included. They all underwent preoperative US, fine needle aspiration cytology (FNAC), per operative frozen section (FS) and post operative definitive pathological analysis. Se, Sp, VPP and VPN of FNAC and FS were calculated and compared (McNemar’s test). Multivariate analysis was performed to identify independent factor of good results. Se of FS and FNAC were, respectively, 86.1 and 81% with significant superiority of FS (p = .0352). Sp of FS and FNAC were, respectively, 100 and 72% with significant superiority of FS (p = .0156). A strategy based only on FNAC would have led to a 3.6% rate of unnecessary total thyroidectomy vs. 0% using FS. Overall rate of second procedure after lobectomy would have been significantly greater 28.9% without (28.9%) than with (10.3%) FS (p = .018). Overall rate of undone one-stage central neck dissection concurrent to total thyroidectomy for MNG would not have been significantly different without (9.4%) and with (2.1%) FS (.058). FNAC alone is unable to determine the extent of thyroid nodule surgery whatever the Bethesda subtype may be. FS significantly decreases the risk of two-stage procedure. For one-stage total thyroidectomy for MNG, the gain with FS is scarce.

      Abstract: Abstract The objective is to investigate whether there is a correlation between the severity of typical brain lesions in congenital cytomegalovirus (cCMV) infection and cochlear implant (CI) outcome. The design of the study is a retrospective single-institutional chart review (2005–2015), performed in a tertiary academic referral center. 23 children with typical signs of cCMV infection on cerebral magnetic resonance imaging (MRI) and bilateral severe-to-profound sensorineural hearing loss were retrospectively evaluated. They were graded in three groups according to the severity of brain involvement. The average implantation age of the first CI is 1.8 years (range 0.6–5.8). Five patients were implanted unilaterally, 18 bilaterally. The average follow-up time after implantation was 3.3 years (range 0.6–6.9). Hearing performance was assessed using the Categories of Auditory Performance (CAP), and speech development was assessed using Speech Intelligibility Rating (SIR). The outcome in each group showed great variation. The majority of children achieved moderate-to-good auditory and speech rehabilitation. The children with severe MRI changes had comparatively better auditory than speech scores. There were children with good auditory performance (CAP ≥6) both in grades II and III, while poor performers (CAP ≤3) were encountered in each group. The severity of brain lesions on its own does not directly correlate with the outcome of cochlear implantation. Despite good retrospective diagnostic evidence of cCMV infection through MRI patterns, this has no predictive role for future hearing and speech rehabilitation.
