  • Malignant otitis externa in a healthy non-diabetic patient
    • Abstract: Abstract A healthy 60-year-old male was initially treated for external otitis, and subsequently received multiple surgeries including abscess drainage, temporal bone debridement, canaloplasty of the external auditory meatus, and fistula excision and was treated with numerous antibiotics at another hospital over a 1-year period. He was seen at our hospital on February 14, 2014 with a complaint of a non-healing wound behind the left ear and drainage of purulent fluid. He had no history of diabetes mellitus or compromised immune function. Computed tomography (CT) and magnetic resonance imaging (MRI) studies at our hospital showed osteomyelitis involving the left temporal, occipital, and sphenoid bones, the mandible, and an epidural abscess. Routine blood testing and tests of immune function were normal, and no evidence of other infectious processes was found. He was diagnosed with malignant otitis externa (MOE). Bone debridement and incision and drainage of the epidural abscess were performed, and vancomycin was administered because culture results revealed Corynebacterium jeikeium, Corynebacterium xerosis, and Enterococcus faecalis. MOE should be considered in healthy patients with external otitis who fail initial treatment.

  • Carotid body tumor: a 25-year experience
    • Abstract: Abstract Carotid body tumor is an uncommon hypervascular benign tumor in the head and neck region. It usually presents as a slow growing mass at the carotid bifurcation. Because of the high rate of neurovascular complications, resection of this tumor is considered challenging for otolaryngologists. Between 1988 and 2013, 40 carotid body tumors from 38 patients were diagnosed and underwent resection at Siriraj Hospital (25 female and 13 male patients). Their age ranged from 15 to 59 years. Seven patients had bilateral tumors simultaneously whereas six cases had familial history of carotid body tumor. Carotid angiography was performed in 29 cases; other additional diagnostic studies included CT scan, MRI, and MRA to detect the widening of carotid bifurcation, its extension, and multifocal tumors. All diagnosed tumors were successfully removed. However, internal carotid artery and carotid bifurcation were injured in 11 cases (27.5 %). Shamblin class III and previous biopsy history were considered risk factors for vascular injury. Postoperative cranial nerves deficit was found in 20 % of the cases and CNS complication occurred in two patients (5 %). There was no surgical mortality. Additionally, upon the mean follow-up period of 36 months, no recurrence or malignant transformation was detected in this study. Multidisciplinary approach, early tumor detection, meticulous preoperative evaluation, and modern vascular surgical technique are the key success factors for tumor removal.

  • Association of history of allergies and influenza-like infections with
           laryngeal cancer in a case–control study
    • Abstract: Abstract Prior studies suggest that history of allergy and infections early in life might be inversely associated with cancer. We explored the association between allergies, recent influenza infections and laryngeal cancer risk. We used data from a case–control study which included 229 cases of laryngeal cancer and 769 population controls matched for age and sex. History of a physician-diagnosed allergy, influenza-like infections in the past 5 years, smoking, alcohol consumption and occupational exposure to carcinogens were self-reported. Allergies were classified into two groups (Type I and Type IV), according to the underlying immunologic mechanism. Conditional logistic regression models were fitted using laryngeal cancer as the outcome, adjusting for smoking, alcohol consumption and occupational exposure and stratified for age and sex. Having any allergy was not associated significantly with laryngeal cancer. Although Type I and Type IV allergies were non-significantly associated with laryngeal cancer, Type IV allergies showed a strong inverse association after adjusting for smoking and alcohol (OR 0.50, 95 % CI 0.22–1.2). Participants who reported at least one influenza-like infection during the past 5 years were significantly less likely to have laryngeal cancer (OR 0.57, 95 % CI 0.39–0.81). After considering fever (≥38.5 °C) as a criterion for influenza infection, the association between influenza infection and laryngeal cancer was even stronger (OR 0.29, 95 % CI 0.13–0.63). We found no significant association between any allergy and laryngeal cancer, some indication of an inverse association between Type IV allergy and laryngeal cancer, whereas recent influenza infections were inversely associated with laryngeal cancer risk.

  • Quality of life assessment in facial palsy: validation of the Dutch Facial
           Clinimetric Evaluation Scale
    • Abstract: Abstract This study aimed at validating an existing health-related quality of life questionnaire for patients with facial palsy for implementation in the Dutch language and culture. The Facial Clinimetric Evaluation Scale was translated into the Dutch language using a forward–backward translation method. A pilot test with the translated questionnaire was performed in 10 patients with facial palsy and 10 normal subjects. Finally, cross-cultural adaption was accomplished at our outpatient clinic for facial palsy. Analyses for internal consistency, test–retest reliability, construct validity and responsiveness were performed. Ninety-three patients completed the Dutch Facial Clinimetric Evaluation Scale, the Dutch Facial Disability Index, and the Dutch Short Form (36) Health Survey. Cronbach’s α, representing internal consistency, was 0.800. Test–retest reliability was shown by an intraclass correlation coefficient of 0.737. Correlations with the House–Brackmann score, Sunnybrook score, Facial Disability Index physical function, and social/well-being function were −0.292, 0.570, 0.713, and 0.575, respectively. The SF-36 domains correlate best with the FaCE social function domain, with the strongest correlation between the both social function domains (r = 0.576). The FaCE score did statistically significantly increase in 35 patients receiving botulinum toxin type A (P = 0.042, Student t test). The domains ‘facial comfort’ and ‘social function’ improved statistically significantly as well (P = 0.022 and P = 0.046, respectively, Student t-test). The Dutch Facial Clinimetric Evaluation Scale shows good psychometric values and can be implemented in the management of Dutch-speaking patients with facial palsy in the Netherlands. Translation of the instrument into other languages may lead to widespread use, making evaluation and comparison possible among different providers.

  • Glottic and supraglottic pT3 squamous cell carcinoma: outcomes with
           transoral laser microsurgery
    • Abstract: Abstract Patients diagnosed with T3 squamous cell laryngeal carcinomas are nowadays offered either organ-preserving surgical or non-surgical treatment, with the optimum approach remaining undefined. No direct comparison of organ-preserving therapeutical options, stratified by anatomical subsites is available in the literature. The aim of this study is to present institutional treatment outcomes for laser-assisted microsurgery (TLM) of laryngeal T3 squamous cell carcinomas and review the relevant literature. Sixty-four consecutive, previously untreated patients were evaluated. Twenty-four supraglottic and 19 glottic patients were treated with TLM and neck dissection, tumor exposure and postoperative upstaging of the tumors through pathology evaluation of the specimens being the only exclusion criteria. Five-year disease-specific survival and organ preservation rates for supraglottic carcinomas were both 91.7 %. The respective values for glottic carcinomas were 63.2 and 73.3 %. TLM-treated T3 supraglottic tumors seem to attribute better outcomes than T3 glottic tumors in terms of recurrence-free survival, organ preservation and local control (p = 0.01, <0.0001 and 0.01, respectively). The results of this study suggest that TLM-treated T3 supraglottic tumors have a good prognosis, substantially better than that of glottic tumors. A literature review, on the other hand, attributes to chemo-radiation-treated T3 supraglottic tumors a considerably poorer prognosis. Further studies of homogenous populations in terms of anatomical subsites are needed in order to reach a consensus regarding treatment of T3 laryngeal tumors.

  • An algorithm for treating extracranial head and neck schwannomas
    • Abstract: Abstract Surgical resection of extracranial head and neck schwannomas (ECHNS) may be associated with major morbidity, but some ECHNSs can be safely treated expectantly. The aim of this study is to present a large case series and an algorithm for therapeutic decision-making in the management of ECHNS. The clinical records of patients diagnosed and treated for ECHNS between 1999 and 2012 at The Tel Aviv Sourasky Medical Center were reviewed retrospectively. All relevant demographic and medical data were extracted, among them presenting symptoms, surgical approaches, nerve of origin, complications and follow-up. A total of 53 patients with ECHNS were included in this clinical study. There were 29 males and 24 females whose mean age was 49.2 years, and all were treated surgically. The schwannomas originated from the brachial plexus, sympathetic chain, vagus nerve, trigeminal nerve, lip, hypoglossal nerve and larynx. Intracapsular enucleation was performed in 32 (60 %) patients, and the remaining 21 (40 %) patients underwent complete excision of the tumor with the involved nerve segment. Thirty-two patients (60 %) had postoperative neurological deficits. This study provides an algorithm to serve as a guideline in the decision-making process for this patient population. Although there is abundant evidence regarding the efficacy of radiotherapy for acoustic schwannoma, the value of radiotherapy as a treatment alternative for patients with ECNHS, especially those unsuitable for surgery, has not been established and further studies are warranted.

  • Endonasal modification of the frontal sinus drainage type IIb according to
           Draf
    • Abstract: Abstract The description of different endonasal drainage options (type I, II and III according to Draf) and their successful use in numerous patients has reached a milestone in frontal sinus surgery. We herein describe a modification of an endonasal frontal sinus drainage type IIb with the additional removal of the lower part of the frontal sinus septum without opening the frontal recess of the other side and without resection of the nasal septum. The modified endonasal endoscopic frontal sinus drainage type IIb was performed on 9 patients at the Department of Otorhinolaryngology, University Medical Center, Homburg/Saar between 02/2011 and 6/2013 after having gained patients’ consent. Follow-ups with endoscopic examination were performed after 6, 12 and 24 months (median follow-up: 14 months). Endonasal endoscopic opening of the frontal sinus was achieved in all patients. Endoscopic examination 6, 12 and 24 months after surgery revealed patent frontal sinus drainage in 8 patients. The frontal sinus drainage could not be visualized endoscopically in one patient who was free of symptoms for 24 months and where a ventilated frontal sinus was proven radiologically by computed tomography. The study demonstrates the option to additionally remove the lower part of the inter-frontal septum with a frontal sinus drainage type IIb. As the number of patients treated by this modified frontal sinus type IIb drainage is limited, further investigations are needed to define the value of a modified frontal sinus drainage type IIb.

  • Hyaluronic acid fat graft myringoplasty vs fat patch fat graft
           myringoplasty
    • Abstract: Abstract We aim to compare the hyaluronic acid to fat graft myringoplasty (HAFGM) technique to a recently described modified-FGM (M-FGM) in the repair of tympanic membrane perforation (TMP). We also aim to evaluate the hearing level improvement postoperatively. We conducted a prospective study in an adult tertiary care center between 2012 and 2013. Adult patients presenting with simple TMP were operated on randomly using either HAFGM or M-FGM under local anesthesia in outpatients’ settings. Success was considered when complete closure is achieved. Audiometric parameters were evaluated pre and postoperatively. Twenty-four patients were included in the study (HAFGM: 10 patients and M-FGM: 14 patients). Complete closure was achieved in 80 % in HAFGM vs 42.8 % in the M-FGM (p = 0.03). The study was abandoned due to the low success rate in first 14 patients of the M-FGM group. The pure tone audiometry was improved postoperatively in the HAFGM only. The study was aborted because of the unsatisfactory obtained results using the MFGM. It also shows the beneficial effect of hyaluronic acid application to FGM for a successful TMP repair.

  • Correlation analysis of STAT3 and VEGF expression and eosinophil
           infiltration in nasal polyps
    • Abstract: Abstract The expression and distribution of signal transducer and activator of transcription 3 (STAT3), phosphorylated STAT3 (p-STAT3), and vascular endothelial growth factor (VEGF), as well as eosinophil infiltration in nasal polyps was detected to examine their roles and correlations in the nasal polyp pathogenesis. Using the streptavidin-biotin-peroxidase (SP) method, immunohistochemistry was performed on conventional paraffin sections of 30 surgery-resected polypous specimens and 10 inferior turbinate tissues that were resected during nasal septum deflection correction to detect the expression of STAT3, p-STAT3, and VEGF, as well as eosinophil infiltration. The rates of STAT3-, p-STAT3-, and VEGF-positive expression in the mucosal epithelium and glands of nasal polyps were 66.67, 56.67, and 76.67 %, respectively, values that were significantly higher than those in the inferior turbinate group. The number of eosinophils in the nasal polyps was significantly higher than in the inferior turbinate group. Expression of p-STAT3 and VEGF in nasal polyps and eosinophil infiltration was increased significantly and positively correlated, indicating that VEGF and eosinophil infiltration might be regulated by p-STAT3. Therefore, the expression of STAT3, p-STAT3, and VEGF, and eosinophil infiltration might be important factors in nasal polyp pathogenesis.

  • Impact of indication-shift of primary and adjuvant chemo radiation in
           advanced laryngeal and hypopharyngeal squamous cell carcinoma
    • Abstract: Abstract Based on level I evidence, postoperative platinum-based radiochemotherapy (PORCT) is the recommended standard of care in defined risk situations after resection of squamous cell carcinomas of the larynx and hypopharynx (LHSCC). The value of the addition of chemotherapy to adjuvant radiation in intermediate and high risk situations other than extracapsular spread or R1-/R2 resection is still debated. From 1993 to 2009, 555 patients (median follow-up: 24.4 months) with advanced LHSCC (UICC stages III–IVB) were treated in a curative intent. Patient data were continuously documented in the county of Leipzig cancer registry and were retrospectively analyzed as mono institutional survey. PORCT was introduced into the standard procedures in 2004, but also applied before in selected cases. Based on this paradigm shift, the patient population was divided into two comparative groups treated before and after 2004. 361 patients were treated before 2004. 43.8 % received primary surgery (OP) + postoperative radiotherapy (PORT) and 20.2 % OP + PORCT. 194 patients were treated after 2004: 21.1 % received OP + PORT and 35.6 % OP + PORCT. Regarding the PORCT groups, 20.6 % received cisplatin plus 5FU before 2004 which shifted to 59.4 % after 2004. The 3-year tumor-specific-survival rate of the whole cohort was improved from 47 to 60 % (p = 0.006). The subgroup treated with OP + PORT or PORCT improved from 56.1 to 68.5 % (p = 0.028). Localization proved to be a significant and independent factor. Only patients with advanced laryngeal cancer had significant improved survival (p < 0.01), while the improvement for hypopharyngeal cancer patients was not significant (p < 0.2). After 2004, there was a slight increase (+10.2 %) of primary radiochemotherapy (pRCT) due to stronger selection if R0 > 5 mm-resectability is unlikely. Standardised use of PORCT and pRCT considering clear indications showed to be significantly involved in improved survival in advanced LHSCC.

  • Perilymphatic fistulas: can we predict the diagnosis'
    • Abstract: Abstract This study intends to identify factors that could better predict the diagnosis of perilymphatic fistula (PLF) since exploration surgery is currently the only confirmatory method. This retrospective chart review in a tertiary care center is based on all 71 available patient files operated for a suspicion of PLF between 1983 and 2012. History of predisposing factors, clinical findings and investigations were documented pre- and postoperatively. Patients were divided according to intraoperative findings into two groups: group I (fistula negative) and group II (fistula positive). In addition, group II was divided into two subgroups: patients with or without a history of stapedectomy. Both groups were demographically similar. With the exception of history of previous partial stapedectomy (p = 0.04), no statistical difference could be identified in predisposing factors and in clinical findings between the two groups. The evolution of symptoms showed an overall improvement of vestibular symptoms (91 %) and cochlear symptoms (53 %) postoperatively. Audiograms showed a significant improvement postoperatively in the pure tone audiometry and bone conduction threshold of group II while the air-bone gap and speech discrimination score did not improve. Group I did not show any significant improvement postoperatively in any audiogram parameter. This study failed to identify factors that could better predict the diagnosis of PLF. However, it shows that middle ear exploration with oval and round window obliteration is effective in PLF especially to decrease vestibular symptoms even when fistula is unidentified intraoperatively.

  • Real-world cost-effectiveness of cetuximab in locally advanced squamous
           cell carcinoma of the head and neck
    • Abstract: Abstract Clinical trial EMR 62202-006 demonstrates prolonged median locoregional control (24.4 vs. 14.9 months), progression-free survival (17.1 vs. 12.4 months) and overall survival (49.0 vs. 29.3 months) for patients who receive cetuximab added to the comparator radiotherapy for locally advanced squamous cell carcinoma of the head and neck (LA SCCHN). In the Netherlands, hospitals receive reimbursement for cetuximab conditional on cost-effectiveness in daily practice. To estimate the real-world incremental cost per quality adjusted life-year (QALY) gained for radiotherapy + cetuximab over radiotherapy alone in first line treatment of LA SCCHN, a Markov model is constructed with health states “alive without progression”, “alive following progression” and “death”. Transition probabilities per month are estimated from clinical trial data and retrospectively collected real-world data from two Dutch head and neck cancer treatment centres (2007–2010, n = 141). 5-year, 10-year and lifetime horizons are used, without and with discounting (4 % costs, 1.5 % effects) to calculate incremental cost-effectiveness ratios. Two scenarios explore different assumptions on prognosis of real-world versus trial patients. Adding cetuximab to radiotherapy results in increased costs and health gains in both scenarios and across each of the time horizons. Incremental costs per QALY gained range between €14,624 and €38,543 in the base-case. For a willingness to pay of €80,000 per QALY, the acceptability curves for the different scenarios show probabilities between 0.76 and 0.87 of radiotherapy + cetuximab being cost-effective compared to radiotherapy alone. Current results show the combined treatment of radiotherapy + cetuximab to be a cost-effective treatment option for patients with LA SCCHN.

  • Adenocarcinomas of the sinonasal tract: a case series from an Oncology
           Centre in Northern Portugal
    • Abstract: Abstract Sinonasal malignant neoplasms are rare and adenocarcinomas account for 10–20 % of these cancers. Our aim is to characterise the clinical presentation, risk factors and outcomes of patients with adenocarcinoma treated at our institution. Retrospective review of medical records of patients with sinonasal adenocarcinomas, treated at IPO-Porto from January 2008 until December 2012. Twenty-eight patients with adenocarcinomas were selected from a total of 53 patients with sinonasal cancers. There was a male predominance (93 %), a mean age at diagnosis of 56 years and a rate of occupational wood dust exposure of 71 %. The most common treatment option was surgery followed by adjuvant radiotherapy. The 5 year disease-free and cancer-specific survival was 58 and 60 %, respectively. The following factors had negative impact on disease-free survival: advanced AJCC stage (p = 0.014); skull base invasion (p = 0.002); poorly differentiated or mucinous subtypes histology (p = 0.034) and imaging findings of residual tumour before adjuvant radiotherapy (p < 0.001). Endoscopic tumour resection was not associated with adverse outcomes. The role of volume-modulated arch therapy in the treatment of sinonasal tumours has to be clarified. The higher rate of adenocarcinomas among sinonasal cancers in this series comparing with previous reports, even from our institution, suggests that this pathology is rising in Northern Portugal. Despite substantial local failure, sinonasal adenocarcinomas have a relatively favourable prognosis in terms of cancer-specific survival.

  • Evaluation of a minimally invasive surgical fixation technique for young
           children with the Concerto Pin cochlear implant system
    • Abstract: Abstract In 2011, Med-El (Innsbruck, Austria) introduced a new cochlear implant system, designed to require a minimally invasive surgical technique and allow greater positional flexibility for its fixation on the skull. The Concerto Pin implant system is a good option for patients with thinner bone, such as children and elderly. The aim of this study was to investigate the implant’s stability in children using our minimally invasive surgical technique. This was a prospective, longitudinal study with a single-subject, repeated-examination design. Six children, implanted with a Concerto Pin using our minimally invasive surgical technique between October 2011 and September 2012, were assessed 1, 3 and 6 months after surgery. In each case, the implant remained in a stable position and no adverse events or problems with healing were observed at any time during the investigation. The minimally invasive technique and the method of implant fixation that bypass drilling a deep implant bed constitute a good option for patients with thinner bone, such as children. This clinical study shows the safety and stability of the Concerto Pin implant system using a minimally invasive surgical technique.

  • Adverse histopathological findings in glottic cancer with anterior
           commissure involvement
    • Abstract: Abstract Open partial horizontal laryngectomy (OPHL) specimens include cartilage and lymph nodes. Pathological adverse findings (PAF): perichondrium, cartilage, perineural invasion, microvessel spread and prelaryngeal metastases can be detected histologically. We aimed at examining PAF in OPHL specimens and examining the interdependence with oncological outcomes. Prospective analysis of 254 glottis cancers: 87-T2a, 77-T2b and 90-T3 with anterior commissure (AC) involvement treated by OPHL at tertiary referral centre between 2001 and 2008. In 38/254 patients (15 %) PAF were found (16 prelaryngeal metastases, 22 other); more often in stage T2b/T3 versus T2a (p = 0.008). PAF other than prelaryngeal metastases were found more often in T2b than T2a tumours (p = 0.005). Outcomes revealed that out of 36 patients with local recurrence, 19 had PAF. Comparison of 216 patients with no PAF and 16 patients with prelaryngeal metastases revealed, respectively: 7.9 versus 81.3 % local recurrences (p = 0.034), 3.2 versus 68.8 % nodal recurrences (p = 0.011), 90.7 versus 43.8 % of 5-year organ preservation (p = 0.021) and 92.6 versus 75 % 5-year overall survival (p = 0.022). Out of 10 patients with close margins, 1 developed the local recurrence; impact for organ preservation and overall survival was not significant. In 22/254 cases including the cartilage into the operating specimen were therapeutically meaningful; in 16/254 with prelaryngeal metastases, the impact for larynx preservation and overall survival was significant. T2b patients had higher probability of PAF than T2a. PAF significantly influenced higher local recurrence rate. This finding ensures the authors, that OPHL type II is not the “overtreatment” compared to the TLM.

  • The effectiveness topical amphotericin B in the management of chronic
           rhinosinusitis: a meta-analysis
    • Abstract: Abstract Chronic rhinosinusitis (CRS) is believed to be the result of an exaggerated reaction to fungi in the nasal mucosa, and topical amphotericin B (AMB) is a commonly used treatment. The purpose of this study was to perform a meta-analysis of high-quality comparative studies to examine the efficacy of topical AMB for the treatment of CRS. A search was conducted of Medline, Cochrane, EMBASE, and ISI Web of Knowledge until December 31, 2013 using combinations of the search terms chronic rhinosinusitis, human, treatment, antibiotics, nasal irrigation, nebulized, nasal lavage, sinonasal rinses, and antimicrobials. Inclusion criteria were (1) comparative studies, (2) a diagnosis of CRS or chronic sinusitis, and (3) the intervention was a topical antifungal. The primary outcome measure was quality of life (QOL), and the secondary was nasal endoscopy score. Of 235 article initially identified, five randomized controlled trials were included in the meta-analysis. Analysis of four studies with complete QOL data found no difference between treatment and placebo groups [standard difference in means 0.78, 95 % confidence interval (CI) −0.25 to 1.81, P = 0.138]. Analysis of four studies with complete nasal endoscopy score data found no difference between the treatment and placebo groups (standard difference in means 0.34, 95 % CI −0.08 to 0.76, P = 0.117). AMB is not more effective than placebo in improving QOL or nasal endoscopy scores in patients with CRS.

  • A genotype–phenotype correlation in Sicilian patients with GJB2
           biallelic mutations
    • Abstract: Abstract The aim of this work was to study the genotype distribution of Sicilian patients with biallelic GJB2 mutations; to correlate genotype classes and/or specific mutations of GJB2 gene (35delG–non-35delG) with audiologic profiles. A total of 10 different mutations and 11 different genotypes were evidenced in 73 SNHL subjects; 35delG (90.36 % of cases) and IVS1+1 (13.69 %) were the most common mutations found in the cohort with a significant difference in the distribution between North and South Sicily. Audiological evaluation revealed a severe (16/73) to profound (47/73) hearing loss (HL) in 86.13 % of cases without significant difference between the degree of HL and the province of origin of the subjects (P = 0.727). The homozygous truncating (T/T) genotype was the most widespread (89.04 % of cases), with a severe-to-profound hearing impairment in 90.36 % of T/T class with respect to truncating/non-truncating (T/NT) and non-truncating/non-truncating (NT/NT) genotypes (P = 0.012). From the comparison of homozygous 35delG and 35delG/non-35delG genotypes, a more profound HL in the homozygous 35delG than in compound heterozygous 35delG/non-35delG (p < 0.0001) resulted. This study confirms that 35delG is the most common mutation in the Mediterranean area with a heterogeneous distribution of the genotypes between North and South Sicily; probands homozygotes for 35delG or presenting a T/T genotype are more apt to have a severe-to-profound HL.
