  • Decision making in dissection range of temporal bone: refinements to
           enlarged translabyrinthine approach
    • Abstract: The aim of the study was to describe the refinements to the classic enlarged translabyrinthine approach (ETLA) by modifying the bony dissection range of temporal bone and to analyze the main outcomes achieved in a series of vestibular schwannoma (VS) cases submitted to microsurgery by ETLA. This was a retrospective study of 382 patients who underwent VS surgical removal via ETLA between January 2001 and December 2012. Among those cases, 332 were via classic ETLA, while 28 cases were via ETLA with blind sac technique and middle ear eradication and 22 via transotic approach. Total tumor removal was achieved in 368 cases, whereas near total removal in 11 patients and subtotal in 3 patients. In cases of large VS (>3 cm) via classic ETLA, good short-term and long-term facial nerve function (HB I–II) was gained in 27.8 % (32/115) and 42.6 % (49/115) cases, respectively, meanwhile in VS operated via blind sac technique, good short-term (p = 0.048) and long-term (p = 0.044) facial nerve function was reached in 44.0 % (22/50) and 60.0 % (30/50) cases, respectively. Postoperative facial nerve function was proved to be better in modified ETLA group. CSF leakage occurred in 16 (4.2 %) patients via classic ETLA. In 115 cases of large VS (>3 cm), postoperative CSF leakage occurred in 10 (8.7 %) patients. Whereas in 50 cases via blind sac technique, none developed CSF leakage (p = 0.03). The incidence of CSF leakage was lower in modified ETLA group. Our refinements to classic ETLA by changing the temporal bone resection range provide a wide surgical field, well prevention of CSF leakage and preservation of facial nerve function in large VS.

  • Comparison of hearing results following the use of NiTiBOND versus Nitinol
           prostheses in stapes surgery: a retrospective controlled study reporting
           short-term postoperative results
    • Abstract: The aim of this retrospective study was to compare the 3-month postoperative hearing results following laser stapedotomy with the use of NiTiBOND versus Nitinol prostheses (31 and 39 patients, respectively). The operations were performed between September 2012 and September 2014, and between March 2006 and December 2012 regarding NiTiBOND and Nitinol, respectively. Twenty of the consecutive 31 patients were female and 11 were male for NiTiBOND, while 11 were male and 28 were female for Nitinol. The mean age was 43.8 years (range 22–61) and 46.9 years (range 28–83) for NiTiBOND and Nitinol, respectively. No significant cochlear trauma was documented postoperatively. The mean air–bone gap (ABG) for the frequencies 0.5, 1, 2 and 3 kHz at the 3-month postoperative follow-up was 7.6 dB (SD 4.7), and 9.3 dB (SD 4.1) for NiTiBOND and Nitinol, respectively. The differences between the mean pre- (p = 0.179), and postoperative (p = 0.059) ABG of the two groups were not significant. ABG closure within 10 dB was achieved in 77.4 and 59 % for NiTiBOND and Nitinol, respectively, the difference was not significant (p = 0.10). Two cases of delayed facial paralysis occurred, 1 with Nitinol and 1 with the NiTiBOND. All patients attained an ABG <20 dB following surgery. Laser stapedotomy with the application of either heat-memory piston prosthesis allowed an easy and minimally invasive approach with excellent short-term hearing results when the NiTiBOND prosthesis was applied. Laser application allowed manipulation in a bloodless environment and avoided manual crimping of the incus.

  • Photocoagulation therapy for laryngeal dysplasia using angiolytic lasers
    • Abstract: In the management of laryngeal pre-cancerous lesions such as dysplasia or carcinoma in situ (CIS), it is important that lesion regression occur without any complications. As a minimally invasive treatment option, photocoagulation therapy using angiolytic lasers has been attracting attention. Therapeutic effects have been reported for this type of treatment, however, vocal function after treatment has not been well discussed. In this retrospective case series, we examined the therapeutic effects of photocoagulation therapy on laryngeal dysplasia and the impact on vocal function. Twenty-four patients with laryngeal dysplasia or CIS were treated with photocoagulation therapy using angiolytic lasers. Two patients were treated under general anesthesia, the remaining 22 patients were treated with topical anesthesia. Before and after treatment the extent of the lesion and vocal function was evaluated by endoscopic examination and acoustic and aerodynamic analyses, respectively. More than 50 % disease regression was observed in 20 of 24 patients. Acoustic and aerodynamic analyses revealed improvement in pitch perturbation quotient with no impairment in other parameters. Photocoagulation therapy using angiolytic lasers has proven to be feasible and safe for the treatment of laryngeal dysplasia.

  • Speech understanding in noise with the Roger Pen, Naida CI Q70 processor,
           and integrated Roger 17 receiver in a multi-talker network
    • Abstract: Roger is a digital adaptive multi-channel remote microphone technology that wirelessly transmits a speaker’s voice directly to a hearing instrument or cochlear implant sound processor. Frequency hopping between channels, in combination with repeated broadcast, avoids interference issues that have limited earlier generation FM systems. This study evaluated the benefit of the Roger Pen transmitter microphone in a multiple talker network (MTN) for cochlear implant users in a simulated noisy conversation setting. Twelve post-lingually deafened adult Advanced Bionics CII/HiRes 90K recipients were recruited. Subjects used a Naida CI Q70 processor with integrated Roger 17 receiver. The test environment simulated four people having a meal in a noisy restaurant, one the CI user (listener), and three companions (talkers) talking non-simultaneously in a diffuse field of multi-talker babble. Speech reception thresholds (SRTs) were determined without the Roger Pen, with one Roger Pen, and with three Roger Pens in an MTN. Using three Roger Pens in an MTN improved the SRT by 14.8 dB over using no Roger Pen, and by 13.1 dB over using a single Roger Pen (p < 0.0001). The Roger Pen in an MTN provided statistically and clinically significant improvement in speech perception in noise for Advanced Bionics cochlear implant recipients. The integrated Roger 17 receiver made it easy for users of the Naida CI Q70 processor to take advantage of the Roger system. The listening advantage and ease of use should encourage more clinicians to recommend and fit Roger in adult cochlear implant patients.

  • Four-phase rhinomanometry: a multicentric retrospective analysis of 36,563
           clinical measurements
    • Abstract: Rhinomanometry can still be considered as the standard technique for the objective assessment of the ventilatory function of the nose. Reliable technical requirements are given by fast digital sensors and modern information technology. However, the xyimaging of the pressure-flow relation typically shows loops as a sign of hysteresis, with the need for resolution of the breath in four phases. The three pillars of 4-phase rhinomanometry (4PR) are the replacement of estimations by measurements, the introduction of parameters related to the subjective sensing of obstruction, and the graphical information regarding the disturbed function of the nasal valve. In a meta-analysis of 36,563 clinical measurements, we analyze the errors of the “classic” parameters (flow in 150 Pa) and reject the further use of these parameters as obsolete, because they correspond to an inaccurate estimation rather than proper measurement. In a pre-study of 1580 measurements, the logarithmic effective resistance (Reff) was found to have the highest correlation with values obtained from a visual analog scale. Next, we classify the inspiratory effective resistance in 20,069 measurements without treatment and 16,494 measurements after decongestion with xylometazoline 0.1 % spray in 20 % percentiles. The gradation of obstruction delivers not only “normal” values but also indications for the severity of the obstruction in adult Caucasian noses. Adoption of the distribution for the growing nose and analysis of the total nasal resistance is addressed, and typical findings of nasal valve phenomena are outlined.

  • GJB2 mutations in deaf population of Ilam (Western Iran): a different
           pattern of mutation distribution
    • Abstract: Hearing loss is the most common sensory defect caused by heterogeneous factors. Up to now, more than 60 mutations in genes have been documented for nonsyndromic hearing loss. Hence, finding the causal gene in affected families could be a laborious and time-consuming process. GJB2 mutations, here, were investigated among deaf subjects of Ilam for the first time. In this study, we studied 62 unrelated patients with non-syndromic autosomal recessive deafness from 62 families. The most common mutation of GJB2, 35delG was checked, followed by direct sequencing of the GJB2 gene for determination of other mutations. In silico analyses were also performed using available software. In nine families, mutations in the connexin 26 gene were observed. In the studied population, R32H was the most common mutation. 35delG, W24X, and R127H were other mutations found in this study. In silico analyses showed pathogenicity of 35delG, R32H, and W24X but not R127H. Low frequency of GJB2 mutations in this population is probably indicative of the fact that other genes may be involved in nonsyndromic hearing loss in Ilam populations. In the other hand, the vicinity of Ilam and Iraq suggests that GJB2 mutations have likely a low frequency in this population.

  • Childhood sensorineural hearing loss: effects of combined exposure with
           aging or noise exposure later in life
    • Abstract: The aim of the study was to examine childhood high-frequency sensorineural hearing loss (HF-SNHL) and the effects of combined exposure with aging or noise exposure on HF hearing thresholds in adulthood. Population-based cohort study of 30,003 adults (mean age 40 years) underwent an audiometry and completed a hearing questionnaire. At age 7–13 years, the same people had participated in a longitudinal school hearing investigation, in which 283 participants were diagnosed with HF-SNHL [PTA 3–8 kHz ≥ 25 dB HL (mean 45 dB HL), worse hearing ear], and 29,720 participants had normal hearing thresholds. The effect of childhood HF-SNHL on adult hearing threshold was significantly moderated by age. Age stratified analyses showed that the difference in HF hearing thresholds between adults with and without childhood HF-SNHL was 33 dB (95 % CI 31–34) in young adults (n = 173, aged 20–39 years) and 37 dB (95 % CI 34–39) in middle-aged adults (n = 110, aged 40–56 years). The combined exposure of childhood HF-SNHL and noise exposure showed a simple additive effect. It appears to be a super-additive effect of childhood-onset HF-SNHL and aging on adult hearing thresholds. An explanation might be that already damaged hair cells are more susceptible to age-related degeneration. To exclude possible birth cohort effects, the finding should be confirmed by a study with several audiometries in adulthood.

  • Evaluation of nasal mucociliary activity in patients with chronic renal
    • Abstract: The ability of respiratory mucosal surfaces to eliminate foreign particles and pathogens and to keep mucosal surfaces moist and fresh depends on mucociliary activity. Chronic renal failure (CRF) is an irreversible medical condition that may result in important extrarenal systemic consequences, such as cardiovascular, metabolic, and respiratory system abnormalities. Although there are studies describing nasal manifestations of CRF, data are lacking concerning the effects of the condition on nasal mucosa. The goal of the current study was to evaluate nasal mucociliary clearance (NMC) time in patients with CRF. This prospective cohort study conducted in a tertiary referral center included 32 non-diabetic end-stage CRF patients and 30 control individuals. The control group consisted of voluntary participants who had been referred to our clinic for symptoms other than rhinological diseases. The mean NMC times in CRF patients and control individuals were 12.51 ± 3.74 min (range 7–22 min) and 8.97 ± 1.83 min (range 6–13 min), respectively. The mean NMC time in patients with CRF was significantly longer than that in control individuals (p < 0.001). Clinicians must keep in mind that NMC time in CRF patients is prolonged and must follow-up these patients more closely for sinonasal and middle ear infections.

  • Impact of nasoseptal flap elevation on sinonasal quality of life in
           endoscopic endonasal approach to pituitary adenomas
    • Abstract: To evaluate the impact of nasoseptal flap (NSF) elevation on sinonasal quality of life (QOL) in patients with pituitary adenomas who underwent endoscopic endonasal trans-sphenoidal approach (EETSA), the data of 106 eligible patients were included from February 2011 to December 2014. The scores of Sinonasal Outcome Test (SNOT-22) Questionnaire were assessed in case (that received reconstruction with NSF) and control groups preoperatively as well as 1, 3, 6, and more than 12 months postoperatively. Nine most related sinonasal questions were evaluated separately (9Q). There were no significant inter-group differences in the mean SNOT-22, 9Q, and sense of taste/smell scores in preoperative and all postoperative assessments. Within each group, a significant improvement of SNOT-22 and 9Q scores were noted after 12 months of surgery compared to preoperative data. In the NSF group, comparison of the pre- and first postoperative evaluation revealed a significant deterioration in 9Q score (p = 0.007) and “sense of taste/smell” (p < 0.001) which both returned to baseline in the 3rd month. Patients who used nasal paper mask for more than 100 “hour-days” showed a better SNOT-22 scores at 1st (p = 0.04) and 3rd (p < 0.001) months after surgery. Patients with adrenocorticotropic hormone (ACTH) secretory adenomas showed significantly higher scores of SNOT-22 in all postoperative assessments compared to the others. Although nasal symptoms deteriorated at first postoperative month (compare to preoperative data) in the NSF group, no negative impacts on the sinonasal QOL was showed comparing to the control group. ACTH-secreting adenomas could be assumed as a risk factor for poorer sinonasal QOL in EETSA.

  • Proposal for a descriptive guideline of vascular changes in lesions of the
           vocal folds by the committee on endoscopic laryngeal imaging of the
           European Laryngological Society
    • Abstract: In the last decades new endoscopic tools have been developed to improve the diagnostic work-up of vocal fold lesions in addition to normal laryngoscopy, i.e., contact endoscopy, autofluorescence, narrow band imaging and others. Better contrasted and high definition images offer more details of the epithelial and superficial vascular structure of the vocal folds. Following these developments, particular vascular patterns come into focus during laryngoscopy. The present work aims at a systematic pathogenic description of superficial vascular changes of the vocal folds. Additionally, new nomenclature on vascular lesions of the vocal folds will be presented to harmonize the different terms in the literature. Superficial vascular changes can be divided into longitudinal and perpendicular. Unlike longitudinal vascular lesions, e.g., ectasia, meander and change of direction, perpendicular vascular lesions are characterized by different types of vascular loops. They are primarily observed in recurrent respiratory papillomatosis, and in pre-cancerous and cancerous lesions of the vocal folds. These vascular characteristics play a significant role in the differential diagnosis. Among different parameters, e.g., epithelial changes, increase of volume, stiffness of the vocal fold, vascular lesions play an increasing role in the diagnosis of pre- and cancerous lesions.

           modulated radiotherapy
    • Abstract: Introduction Esthesioneuroblastoma is a rare tumour of the sino-nasal tract. One-third cases present with intracranial extension. However, treatment options are limited for such cases. Methodology We herein report a case with large intracranial extension treated with Induction chemotherapy, de-bulking surgery, and image guided intensity modulated radiotherapy. Results The patient was treated with IGIMRT technique to a dose of 64 Gy in 32 fractions. Cone bean CT verification was done twice a week to eliminate set up error. The patient achieved complete resolution of the disease and was disease free 6 months after completion of treatment. Conclusion IGIMRT even after a de-bulking surgery may help to achieve long-term disease control for patients with large intracranial extension with minimal morbidity.

  • Antibiotic efficacy in patients with a moderate probability of acute
           rhinosinusitis: a systematic review
    • Abstract: The aim of this systematic review was to synthesize the results of original studies assessing antibiotic efficacy at different time points after initiating treatment in patients with a moderate probability of acute bacterial rhinosinusitis. We searched the Cochrane library for systematic reviews on the efficacy of antibiotic treatment in patients with acute rhinosinusitis (ARS). Only randomized controlled trials (RCTs) that compared treatment of any antibiotic with placebo were included. The synthesis of the results of six RCTs showed a benefit of antibiotic treatment compared to placebo for the rate of improvement after 3 [pooled odds ratio (OR) 2.78 (95 % confidence interval (CI) 1.39–5.58)] and 7 [OR 2.29 (95 % CI 1.19–4.41)] days after initiation in patients with symptoms and signs of ARS lasting for 7 or more days. After 10 days [pooled OR 1.36 (95 % CI 0.66–2.90)], improvement rates did not differ significantly between patients treated with or without antibiotics. Compared to placebo, antibiotic treatment relieves symptoms in a significantly higher proportion of patients within the first days of treatment. Reporting an overall average treatment efficacy may underestimate treatment benefits in patients with a self-limiting illness.

           Otorhinolaryngology-Head and Neck Surgery Examination (EBEORL-HNS)
    • Abstract: The UEMS Otorhinolaryngology-Head and Neck Surgery section is a dedicated body formed to promote the standardisation and harmonisation of European Otorhinolaryngology (ORL). The European Examination Board of Otorhinolaryngology and Head and Neck Surgery was created to establish a supranational final exam and accreditation for ORL Surgeons. It is open to candidates both from the European Union and outside the EU. The exam is composed of a written examination to assess mainly the theoretical knowledge of Otorhinolaryngological diseases. The second part, a viva voce examination, is designed to test the clinical application of knowledge based on case scenarios and clinical conditions presented to the candidates. The inaugural examination written component took place in Mannheim/Germany in 2009 and the inaugural Viva Voce examination in Vienna/Austria in 2010. Up to and including the year 2013, 858 participants have attempted one of the two exam components. Of the 858 participants, 305 were successful in both examinations and obtained the accreditation of the European Diploma (European Board Certification). The historical origins, development of the examination, its formal arrangements and the format of the examination are presented in this article.

  • A single-item screening question for fear of recurrence in head and neck
    • Abstract: Fear of recurrence (FoR) is the most frequent concern patients wish to discuss in head and neck review clinics. The aim of the study was to design a simple screening question on fear of recurrence to be incorporated into the University of Washington Quality of Life Questionnaire (UW-QOLv4), for use in clinical practice. A cross-sectional survey comprising 528 patients was conducted. 11 % selected the two most severe FoR categories. FoR responses correlated strongly (Spearman r s = −0.82) with the mean score of the seven items of the Fear of Recurrence Questionnaire. There was also a strong association with anxiety and mood dysfunction as measured from the UW-QOL, and with overall QOL. Patients more affected by FoR tended to be younger and post-radiotherapy or chemotherapy. The FoR screening question may be a useful addition to the UW-QOLv4 to help identify patients with significant FoR to receive extra support.

  • Long-term results of one staged multilevel surgery with tongue suspension
           surgery or one level palatal surgery for treatment of moderate and severe
           obstructive sleep apnea
    • Abstract: The objective of this study is to evaluate and compare the long-term efficacy of the one staged multilevel surgery (MLS) with tongue suspension (TBS) surgery or one level palatal surgery for treatment of moderate and severe obstructive sleep apnea (OSA). This is a prospective cross-sectional study. Setting: University hospital. Thirty-three patients diagnosed as moderate to severe OSA. Patients, with ≥50 % retropalopharyngeal obstruction on the Müller maneuver, were treated with palatal surgeries (PS) and patients, with ≥50 % retropalopharyngeal obstruction on the Müller maneuver with ≥50 % base of the tongue collapse, were treated with palatal surgeries and tongue suspension surgery (TBS). Patients were evaluated with one night polysomnography before the surgery and 24 months after the surgery. Patients completed Epworth sleepiness scale (ESS), snoring VAS (visual analog scale) before and 24 months after the surgery. Nine-teen patients with a mean age of 46.1 ± 8.3 underwent palatal surgeries (PS) and 14 patients with a mean age of 41.4 ± 8.9 underwent PS plus TBS. Success rate in TBS+PS group was 57.1 % and in PS group was 42.1 %. In both groups total apnea–hypopnea index (AHI) values significantly decreased after 2 years (p < 0.025) but there was no statistically significant difference between TBS+PS and PS groups. Supine AHI levels were reduced statistically significant in both groups postoperatively (p < 0.025). There was not any significant difference postoperatively in non-supine AHI levels in both groups (p > 0.025). There were significant postoperative changes in ODI, AVO2, MOS, ESS, Snoring VAS values in PS group (p < 0.025). In TBS+PS group there was a significant difference postoperatively only in ODI values. Treatment of OSA patients with retropalatal or retropalatal and retroglossal obstruction, in a one staged surgery, is a safe and easy procedure. We have achieved favorable long-term outcomes in moderate–severe OSA patients undergoing both palatal surgery and tongue suspension surgery.

  • Preoperative localization of hyperfunctioning parathyroid glands with
    • Abstract: Primary hyperparathyroidism (pHPT) is almost exclusively the result of a solitary parathyroid adenoma. In most cases, the affected gland can be surgically removed, but precise preoperative imaging is essential for adenoma localization prior to surgical intervention. In this study, we evaluated the diagnostic value of four-dimensional computed tomography (4D-CT) as a preoperative imaging tool in relation to the localization of pathologic parathyroid glands in patients with pHPT and negative sestamibi scans. This study included 43 consecutive patients with pHPT referred for parathyroidectomy at the Department of Head and Neck Surgery of Copenhagen University Hospital Rigshospitalet in 2011 and 2012. All patients had a 4D-CT performed prior to parathyroidectomy. CT localization of the suspected adenoma was correlated to the actual surgical findings and subsequent histological diagnosis was also available as references for the accuracy of this imaging tool. Hyperfunctioning parathyroid glands were found in 40 patients. 4D-CT identified 32 solitary hyperfunctioning parathyroid glands located on the correct side of the neck (PPV 76 %) and 21 located within the correct quadrant (PPV 49 %). Unilateral resection was performed in 72 % of patients due to the localization findings of preoperative imaging. 4D-CT can, therefore, be considered an effective method for the preoperative localization of parathyroid adenomas and is an important tool in surgical intervention for patients referred to parathyroidectomy.

  • TMPRSS3 mutations in autosomal recessive nonsyndromic hearing loss
    • Abstract: Nonsyndromic genetic deafness is highly heterogeneous in its clinical presentation, pattern of inheritance and underlying genetic causes. Mutations in TMPRSS3 gene encoding transmembrane serine protease account for <1 % of autosomal recessive nonsyndromic hearing loss (ARNSHL) in Caucasians. Targeted next generation sequencing in the index family with profound deaf parents and a son, and Sanger sequencing of selected TMPRSS3 gene regions in a cohort of thirty-five patients with suspected ARNSHL was adopted. A son and his mother in the index family were homozygous for TMPRSS3 c.208delC (p.His70Thrfs*19) variant. Father was digenic compound heterozygote for the same variant and common GJB2 c.35delG variant. Three additional patients from the ARNSHL cohort were homozygous for TMPRSS3 c.208delC. TMPRSS3 defects seem to be an important cause of ARNSHL in Slovenia resulting in uniform phenotype with profound congenital hearing loss, and satisfactory hearing and speech recognition outcome after cochlear implantation. Consequently, TMPRSS3 gene analysis should be included in the first tier of genetic investigations of ARNSHL along with GJB2 and GJB6 genes.

  • A novel nasopharyngeal stent for the treatment of obstructive sleep apnea:
           a case series of nasopharyngeal stenting versus continuous positive airway
    • Abstract: The objective of the study was to investigate the first-night treatment success of a nasopharyngeal stent compared to standard nCPAP-titration. This is a case series and a single-center study. Eight participants (n = 8) were selected with untreated obstructive sleep apnea with a prestudy AHI ≥10. A newly developed nasopharyngeal stent was tested individually versus standard nCPAP-titration. Cardiorespiratory polysomnography was performed on two consecutive nights (random order: stent, nCPAP). The AHI, the number of obstructive apneas and hypopneas, the mean oxygen saturation, and the minimum oxygen saturation were compared before and after using the nasopharyngeal stent or standard nCPAP. The AHI value before treatment (AHIpre) was 31.1 ± 12.0 (mean ± standard deviation). After inserting the AlaxoStent, the mean AHIstent was 19 ± 12.0 compared to mean AHInCPAP 8.2 ± 11.9 with standard nCPAP-titration. Both nasopharyngeal stenting and nCPAP-titration could reduce the mean number of obstructive apneas by >94 %. Compared to responder rates of classic surgical interventions like uvulopalatopharyngoplasty or multi-level surgery, the nasopharyngeal stent seems to give a comparable responder rate of 50 %. There were no complications associated with the use of the stent and it was well tolerated by all subjects. Nasopharyngeal stenting widens the range of non-invasive mechanical treatment and seems to be an effective mechanical therapeutic alternative to surgery in nCPAP non-compliant patients with OSA. Careful selection of the patient population is a prerequisite of treatment and therefore it should be reserved for individual cases only.
