Abstract
A 41-year-old female patient presented due to acute onset of unilateral hearing loss 3 months previously and persistent since then. Systemic therapy with oral glucocorticoids in decreasing doses had been performed beforehand, but did not lead to any improvement. In the course of audiological diagnostics, based on subjective and objective methods, a retrocochlear hearing disorder was suspected. A meningioma was diagnosed by diagnostic imaging. Subsequent surgical removal achieved a significant hearing improvement.

Abstract
Spiral ganglion neurons (SGNs) facilitation properties can be recorded utilizing electrically evoked compound action potential (ECAP). While intracochlear variation of the ECAP threshold in relation to its electrode channel is reported, no study investigated its impact on facilitation. In this study, we quantified intracochlear variation of the facilitation properties in cochlear implants (CI) using ECAPs. We hypothesized that the facilitation effect is dependent on the electrode channel and its ECAP threshold. Therefore, ECAPs were recorded in 23 CI subjects. For each subject, five default (channel-derived) and up to two additional (threshold-derived) stimulation sites were defined. Facilitation was quantified by the paradigm introduced by (Hey et al., 2017) with optimized parameter settings. For each channel the maximum facilitated amplitude was determined by a series of ECAP measurements. A linear mixed-effects model was used to investigate the impact of the electrode channel and ECAP threshold on the maximum facilitated amplitude. The maximum facilitated amplitude was found to be dependent on the ECAP threshold and independent on the electrode channel. We conclude that the facilitation paradigm is a useful and feasible tool to gain local information on the SGNs temporal processing patterns.

Abstract
IntroductionThe objective of this study was to determine whether postoperative additive systemic steroid administration in chronic rhinosinusitis with nasal polyps (CRSwNP) impacted selected endoscopic, subjective and objective outcome measures.MethodsThis was a prospective, randomized, double-blind, placebo-controlled, noninferiority multicenter trial of n=106 patients with CRSwNP. All patients underwent primary functional endoscopic sinus surgery (FESS) followed by topical nasal steroids. Patients were randomized to a systemic steroid or placebo for 1 month. Patients were followed up for 2 years over 9 time points. The primary outcome measures were the differences between groups with respect to the nasal polyp score (NPS) and sinonasal quality of life (SNQoL). Secondary outcome measures included interactions with respect to the Lund-Kennedy score (LKS), sinonasal symptoms, general quality of life (GQoL), 16-item odor identification test scores, recurrence rates, need for revision surgery and mucus biomarker levels.Results106 patients were randomized to either the placebo or the systemic steroid group (n=53 per group). Postoperative systemic steroids were not superior to placebo with respect to all primary (p= 0.077) and secondary outcome measures (p>0.05 for all). Reported adverse events were similar between the two groups.ConclusionIn conclusion, the addition of postoperative systemic steroids after primary FESS did not confer a benefit over topical steroid nasal spray alone with respect to NPS, SNQOL, LKS, GQOL, sinonasal symptoms, smell scores, recurrence rates, the need for revision surgery or biomarkers over a short-term follow-up of up to 9 months and a long-term follow-up of up to 24 months in CRSwNP patients. Functional endoscopic surgery did, however, show a strong effect on all outcome measures, which remained relatively stable up to the endpoint at 2 years.

Abstract
Hintergrund Ab Frühjahr 2020 kam es zur weltweiten Verbreitung von SARS-CoV‑2 mit der heute als erste Welle der Pandemie bezeichneten Phase ab März 2020. Diese resultierte an vielen Kliniken in Umstrukturierungen und Ressourcenverschiebungen. Ziel unserer Arbeit war die Erfassung der Auswirkungen der Pandemie auf die universitäre Hals-Nasen-Ohren(HNO)-Heilkunde für die Forschung, Lehre und Weiterbildung. Material und Methoden Die Direktorinnen und Direktoren der 39 Universitäts-HNO-Kliniken in Deutschland wurden mithilfe einer strukturierten Online-Befragung zu den Auswirkungen der Pandemie im Zeitraum von März bis April 2020 auf die Forschung, Lehre und die Weiterbildung befragt. Ergebnisse Alle 39 Direktorinnen und Direktoren beteiligten sich an der Umfrage. Hiervon gaben 74,4 % (29/39) an, dass es zu einer Verschlechterung ihrer Forschungstätigkeit infolge der Pandemie gekommen sei. Von 61,5 % (24/39) wurde berichtet, dass pandemiebezogene Forschungsaspekte aufgegriffen wurden. Von allen Kliniken wurde eine Einschränkung der Präsenzlehre berichtet und 97,5 % (38/39) führten neue digitale Lehrformate ein. Im Beobachtungszeitraum sahen 74,4 % der Klinikdirektoren die Weiterbildung der Assistenten nicht gefährdet. Schlussfolgerung Die Ergebnisse geben einen Einblick in die heterogenen Auswirkungen der Pandemie. Die kurzfristige Bearbeitung pandemiebezogener Forschungsthemen und die Einführung innovativer digitaler Konzepte für die studentische Lehre belegt eindrücklich das große innovative Potenzial und die schnelle Reaktionsfähigkeit der HNO-Universitätskliniken, um auch während der Pandemie ihre Aufgaben in der Forschung, Lehre und Weiterbildung bestmöglich zu erfüllen.

Abstract
Previous studies describe a correlation between HPV-positivity and non-smoking in TSCC; p16INK4A-expression as surrogate-marker for HPV-DNA/RNA-positivity is discussed controversially. In the present study, these parameters are assessed prospectively. HPV-status of sputum and tonsillar-swabs was analyzed to determine their validity as surrogate-marker for tissue-HPV-status. TSCC- (n = 52) and non-neoplastic tonsillar tissue (n = 163) were analyzed. HPV-DNA- and HPV-RNA-status of total sputum, cellular fraction and supernatants, tonsillar-swabs and -tissue was determined by (RT)-PCR. Immunohistochemistry determined p16INK4A-expression. 23/163 (14.2%) non-neoplastic tonsils were HPV-DNA-positive; five patients (3 HPV16, 2 HPV11) had active HPV-infections (HPV-RNA-positive), in all biomaterials. 140/163 (85.9%) patients were either HPV-DNA-positive or HPV-DNA-negative in all samples. 21/52 (40.4%) TSCC-tonsils were HPV-DNA-positive; 17 patients were HPV-RNA-positive (14 HPV16; 4 HPV18). 40/52 (76.9%) TSCC-patients were congruent in all biomaterials. p16INK4A-expression alone would have misclassified the HPV-status of 14/52 (26.2%) TSCC-patients. This prospective study confirms the discrepancy between HPV-status and p16INK4A-expression and the significant correlation between non-smoking and HPV-DNA-positivity. HPV-sputum- and/or swab-results do not consistently match tissue-results, possibly having (detrimental) consequences if those were used to assess tissue-HPV-status. In the 5 patients with active HPV infection in the non-neoplasitic tonsils, tonsillectomy likely prevented subsequent development of TSCC.

Abstract
INTRODUCTION Since December 2019, the SARS-CoV-2 virus has been rapidly spreading worldwide. In Germany, an exponential increase in the number of infections was registered at the beginning of March 2020 and led to a call of the Ministry of Health to create more capacity for intensive medical treatment in hospitals. The aim of the present study was to determine the effects of the SARS-CoV-2 pandemic on Oto-Rhino-Laryngology (ORL) university hospitals regarding patient care. MATERIALS AND METHODS An online survey was sent out to all chairmen of the 39 ORL university hospitals in Germany. The answers to the questions referred to the defined period from March 15th to April 15th 2020 and were carried out using the online survey tool "SurveyMonkey". 87 questions focused on general information, health care, and structural effects in the respective institution. RESULTS All chairmen of the 39 university hospitals in Germany participated in the survey. The collected data prove the considerable impact on organizational, structural and medical aspects of patient care. For example, the surveyed clinics reported a decrease in outpatient cases by 73.8 % to 26.2 ± 14.2 % and in surgical treatments by 65.9 % to 34.1 ± 13.9 %. In contrast, emergency treatment remained unchanged or even increased in 80 % of the facilities and surgical treatment of emergency patients remained unchanged or even increased in more than 90 %. Emergency outpatient and surgical treatment of patients was provided throughout the pandemic in all facilities. In total, about 35 000 outpatients and about 12 000 surgical cases were postponed. As a result of the acute structural changes, the potential danger of falling below current treatment standards was seen in individual areas of patient care. DISCUSSION The assessment of the impact of the SARS-CoV-2 pandemic is heterogeneous. The majority of the chairmen are critically aware of the risk of falling below current medical treatment standards or guidelines. In the phase of an exponential increase in the number of infections, significant changes in treatment processes had to be accepted for understandable reasons. However, with the currently significantly reduced number of infections, falling below treatment standards and guidelines should not be allowed to remain constant and tolerated. SUMMARY This study shows a differentiated picture with regard to the effects of the SARS-CoV-2 pandemic on outpatient, inpatient and operative patient care at the ORL university hospitals in Germany and illustrates the importance of these institutions for ensuring patient care during this critical phase.

Abstract
BACKGROUND As part of postoperative cochlear implant (CI) diagnostics, speech comprehension tests are performed to monitor audiological outcome. In recent years, a trend toward improved suprathreshold speech intelligibility in quiet and an extension of intelligibility to softer sounds has been observed. Parallel to audiometric data, analysis of the patients' acoustic environment can take place by means of data logging in modern CI systems. OBJECTIVES Which test levels reflect the individual listening environment in a relevant manner and how can these be reflected in a clinical audiometric setting? PATIENTS AND METHODS In a retrospective analysis, data logs of 263 adult CI patients were evaluated for sound level and the listening situation (quiet, speech in quiet, noise, speech in noise, music, and wind). Additionally, monosyllabic word comprehension in quiet was analyzed in experienced CI users at presentation levels of 40-80 dB. RESULTS For the sound level in the acoustic environment of postlingually deafened adult CI users, data logging shows a maximum occurrence of speech signals in the range 50-59 dB. This demonstrates the relevance of everyday speech comprehension at levels below 60 dB. CONCLUSIONS Individual optimization of speech intelligibility with a CI speech processor should not be performed in the range of 65-70 dB only, but also at lower levels. Measurements at 50 dB currently seem to be a useful addition.

Abstract
INTRODUCTION Transoral laser microsurgery (TLM) is an accepted and effective treatment strategy for supraglottic carcinomas. Early supraglottic carcinoma has excellent outcomes independently of the treatment approach. The role of TLM for the treatment of locally advanced tumors is debated. Particularly, the functional outcomes after TLM have to be proven by functional assessment of large cohorts of patients. This study analyzes the oncologic and functional outcomes after TLM for supraglottic carcinomas. PATIENTS AND METHODS Ninety-one patients with pT1-pT4a supraglottic carcinomas treated between January 2002 and December 2012 were analyzed. Distribution of tumors (UICC 2010) was 11 patients with pT1, 31 patients with pT2, 36 patients with pT3, and 13 patients with pT4a tumors. Node status was positive in 40 (43.6%) patients; 61 (67.1%) patients had stage III or IVa disease. Local control and survival were estimated using the Kaplan-Meier method. For the assessment of functional outcomes, the MD Anderson Dysphagia Inventory (MDADI), the Voice Handicap Index-10 (VHI-10), and the performance status scale for head and neck cancer [Performance Status Scale for Head and Neck (PSS-HN)] were used. RESULTS The median age was 62 years (range, 33-88 years). Fourteen (15.4%) patients developed a local or locoregional recurrence. The 5-year local control rate and 5-year ultimate local control rate were 72 and 92%, respectively. The 5-year overall survival rate was 63%. Twelve (13.2%) patients needed temporary tracheostomy. Sixty-eight (74.0%) patients had a nasogastric feeding tube post-operatively. At 1-year post-operative follow-up, only three patients were PEG dependent. The median VHI-10 score was 35, the median MDADI composite score was 80, and the median score of the domain "normalcy of diet" in the PSS-HN was 91. CONCLUSION The oncologic outcomes are comparable to the results of open surgery for early and advanced supraglottic carcinomas. Functional swallowing outcome is superior to open surgery and to concomitant chemoradiation. Patients treated with TLM perceive low levels of voice- and swallowing-related quality of life impairment.

Abstract
A new member of the lysyl oxidase (LOX) family, lysyl oxidase-like 4 (LOXL4), is overexpressed in head and neck squamous cell carcinoma (HNSCC) compared to normal squamous epithelium. A monoclonal antibody (mAb) derived from fusion of Balb/c mouse splenocytes immunized with LOXL4 specific peptide was used to evaluate its therapeutic efficacy in 15 HNSCC cell lines associated with LOXL4 overexpression. For xenograft experiments 41 severe combined immunodeficient (SCID) mice were used to analyze LOXL4-mAb mediated tumor regression. Cell viability was analyzed using cytotoxicity-, and clonogenic-assays. Significant suppression of tumor cell growth was observed in 12 out of 15 (80%) tumor cell lines after 48 hr exposure to the mAb (LD50 of 15 µg/ml to 45 µg/ml). The effect induced by the antibody could be blocked by pre-incubation of the antibody with the peptide used for immunization of the mice and antibody generation, indicating that the effect of the antibody is specific. In mice inoculated with HNSCC cells, i.v. injections of the LOXL4-mAb resulted within 70 days in extensive tumor destruction in all treated animals whereas no tumor regression occurred in control animals. In mice pre-immunized i.v. with LOXL4-mAb and subsequently injected with HNSCC cells, tumor development was considerably delayed in contrast to non LOXL4-mAb pre-immunized animals. These results demonstrate that the LOXL4-mAb has potent antitumor activity and suggest its suitability as a therapeutic immune agent applicable to HNSCC exhibiting tumor specific upregulation of LOXL4.

Abstract
INTRODUCTION Besides an obvious clinical involvement of the ear, nose and throat (ENT)-region in Eosinophilic Granulomatosis with Polyangiitis (EGPA), systematic data is sparse. Only a few case series and case reports are available that particularly describe rhinological, otological or other manifestations of EGPA in the ENT-region. Therefore, the objective of this study is to systematically describe data on ENT-region involvement in a large series of EGPA patients. METHOD EGPA patients examined in the Department of Otorhinolaryngology of the Christian-Albrechts-University of Kiel between 1990 and 2010 were included in the study. Criteria for ENT-manifestation were assigned to five subgroups (history, ENT examination, audiological and rhinological diagnostic findings and cranial MRI) and documented cumulatively. EGPA patients were examined in a standardized way based on the validated Ear Nose and Throat Activity Score (ENTAS) or its precursor, including audiological and rhinological diagnostic findings. MRI scans were analysed to further evaluate ENT involvement. RESULTS A total of 95 EGPA patients were included in the study. In approximately 80% of them, ENT-involvement was documented and the assumption of a frequent rhinological manifestation in patients with EGPA was confirmed. Moreover, the data reveals remarkable evidence for an otological manifestation. A missing correlation between the rhinological and the otological manifestation indicates an independent autoimmune-inflammatory process for this manifestation. CONCLUSION The data of the largest monocentric study presented here confirms the hypothesis of a frequent ENT involvement in EGPA patients, in whom rhinological and otological manifestations are most common. Therefore, treatment should include long term follow-up and should be managed interdisciplinary.

Abstract
INTRODUCTION A survey was conducted to assess the level of knowledge on oral cancer among different medical fields, in particular about diagnostic items and risk factors. MATERIAL AND METHODS A self-administered questionnaire was mailed to physicians from various fields, such as otorhinolaryngology, general practice, internal medicine, and dermatology. RESULTS 388 of the 2,952 questionnaires were returned (13.1%), subdivided into otorhinolaryngology (n = 33), internal medicine (n = 135), dermatology (n = 28), and general practice (n = 192). The average knowledge of risk factors was similar in the specialisations, ranging from 68% for internal medicine to 76% for otorhinolaryngology and 77% for dermatology. The three main risk factors: tobacco (93%-100%), alcohol (79%-100%), and prior oral cancer lesions (91%-100%) were the most commonly known. Regarding the diagnostic items, the average percentage of correct answers ranged from 69% for internal and general medicine to 77% for dermatologists. Continuous courses of education and the year of graduation were the only two variables that significantly related to a better level of knowledge of risk factors and diagnostic items. CONCLUSIONS The average knowledge among the different medical fields was satisfying. These results demonstrated a robust base for all healthcare providers to continue working together to improve the early detection of oral cancer.

Abstract
BACKGROUND AND STUDY AIMS Insertion of a percutaneous endoscopic gastrostomy (PEG) is standard care for many patients with oropharyngeal (ENT) and esophageal malignancies in order to ensure enteral feeding. The current pull-through insertion technique involves direct contact with the tumor and case reports have demonstrated the presence of metastases at insertion sites. The aim of the current study was to prospectively evaluate the risk of malignant cell seeding and the development of abdominal wall metastases after PEG placement. PATIENTS AND METHODS A total of 50 consecutive patients with ENT/esophageal tumors were included. After PEG placement (40 pull-through technique, 10 direct insertion), brush cytology was taken from the PEG tubing and the transcutaneous incision site. A second cytological assessment was performed after a follow-up period of 3 - 6 months. RESULTS In total, 26 patients with ENT cancer, 13 with esophageal cancer, and one with esophageal infiltration of lung cancer underwent pull-through PEG placement with no immediate complications. Cytology following brushing of tubing and incision sites demonstrated malignant cells in 9 /40 cases (22.5 %). Correlation analyses revealed a higher rate of malignant seeding in older patients and in those with higher tumor stages. At follow-up, cytology was undertaken in 32 /40 patients who had undergone pull-through PEG placement. Malignant cells were present in three on cytology, resulting in a metastatic seeding rate of 9.4 %. CONCLUSION This study showed that malignant cells were present in 22.5 % of patients immediately after pull-through PEG placement; local metastases were verified at follow-up in 9.4 %, all of which were from esophageal squamous cell carcinoma. This risk is particularly high in the older age group and in patients with higher tumor stages. Therefore, pull-through PEG placement should be avoided in these patients and direct access PEG favored instead.

Abstract
Objectives Palytoxin (PTX), a marine toxin isolated from the Cnidaria (zooanthid) Palythoa caribaeorum is one of the most potent non-protein substances known. It is a very complex molecule that presents both lipophilic and hydrophilic areas. The effect of PTX was investigated in a series of experiments conducted in head and neck squamous cell carcinoma (HNSCC) cell lines and xenografts. Materials and methods Cell viability, and gene expression of the sodium/potassium-transporting ATPase subumit alpha1 (ATP1AL1) and GAPDH were analyzed in HNSCC cells and normal epithelial cells after treatment with PTX using cytotoxicity-, clonogenic-, and enzyme inhibitor assays as well as RT-PCR and Northern Blotting. For xenograft experiments severe combined immunodeficient (SCID) mice were used to analyze tumor regression. The data were statistically analyzed using One-Way Annova (SPSS vs20). Results Significant toxic effects were observed in tumor cells treated with PTX (LD50 of 1.5 to 3.5 ng/ml) in contrast to normal cells. In tumor cells PTX affected both the release of LDH and the expression of the sodium/potassium-transporting ATPase subunit alpha1 gene suggesting loss of cellular integrity, primarily of the plasma membrane. Furthermore, strong repression of the c-Jun N-terminal kinase 3 (JNK3) mRNA expression was found in carcinoma cells which correlated with enhanced toxicity of PTX suggesting an essential role of the mitogen activated protein kinase (MAPK)/JNK signalling cascades pathway in the mechanisms of HNSCC cell resistance to PTX. In mice inoculated with carcinoma cells, injections of PTX into the xenografted tumors resulted within 24 days in extensive tumor destruction in 75% of the treated animals (LD50 of 68 ng/kg to 83 ng/kg) while no tumor regression occurred in control animals. Conclusions These results clearly provide evidence that PTX possesses preferential toxicity for head and neck carcinoma cells and therefore it is worth further studying its impact which may extend our knowledge of the biology of head and neck cancer.

Abstract
Introduction In granulomatosis with polyangiitis (GPA), a complex autoimmune small-vessel vasculitis frequently associated with chronic necrotizing inflammation of the nasal mucosa, elevated nasal Staphylococcus (S.) aureus carrier rates are a risk factor for relapse. As cytokines are primarily involved in the regulation of defense against potentially pathogenic microorganisms, the aim of this study was to compare healthy individuals and GPA patients with respect to their baseline cytokine expression of nasal epithelial cells (NEC), which form the first barrier against such triggers. The ability of S. aureus to influence the nasal microenvironment's cytokine secretion was assessed by exemplary stimulation experiments. Methods Baseline expression of 19 cytokines of primary NEC of GPA patients and normal controls (NC) was quantified by a multiplex cytokine assay. Stimulation experiments were performed with supernatants of S. aureus and expression of interleukin-8 was determined by ELISA. Results In GPA, an altered pattern of baseline cytokine expression with significantly up-regulated G-CSF and reduced interleukin (IL)-8 concentrations was observed. Both NEC of GPA patients and NC responded to stimulation with S. aureus, but GPA patients displayed a significantly lower IL-8 secretion and a diminished dynamic range of response towards the stimulus. Conclusions The data presented underline the hypothesis of a disturbed epithelial nasal barrier function in GPA. The dysregulated baseline expression of G-CSF and IL-8 and the reduced response to microbial stimulation may facilitate changes in the composition of the nasal flora and favour an imbalanced inflammatory response, which might be relevant for the disease course.

Abstract
The principles of open versus laser microsurgical approaches for partial resections of the larynx are described, oncologic as well as functional results discussed and corresponding outcomes following primary radiotherapy are opposed. Over the last decade, the endoscopic partial resection of the larynx has developed to an accepted approach in the treatment of early glottic and supraglottic carcinomas thus leading to a remarkable decline in the use of open surgery. Comparing the various surgical approaches of laryngeal partial resections, the oncological outcome of the patients, as far as survival and organ preservation are concerned, are comparable, whereas functional results of the endoscopic procedures are superior with less morbidity. The surgical procedures put together, are all superior to radiotherapy concerning organ preservation. Transoral laser microsurgery has been used successfully for vocal cord carcinomas with impaired mobility or fixation of the vocal cord, supraglottic carcinomas with infiltration of the pre- and/or paraglottic space as well as for selected hypopharyngeal carcinomas. It has been well documented that laser microsurgery achieves good oncological as well as functional results with reasonable morbidity. However, patients with those tumours have been successfully treated by open partial resections of the larynx at medical centres with appropriate expertise. The initially enthusiastic assessment of study results concerning the efficacy of various protocols of chemoradiation with the intent of organ preservation for laryngeal and hypopharyngeal carcinomas are judged more cautious, today, due to recent reports of rather high rates of late toxicity complications.

Abstract
Cortical attention and habituation parameters are altered in patients suffering from tinnitus. The aim of the study was to quantify cortical attention and habituation parameters in tinnitus patients by recording the contingent negative variation (CNV) response and to correlate amplitudes of different CNV parameters with duration of disease. Twenty patients suffering from tinnitus (median: 44 years) and twenty age- and sex-matched healthy controls (median: 41 years) were tested by a CNV paradigm. We recorded overall CNV, initial CNV, and terminal CNV and calculated habituation slopes. All CNV parameters were Spearman-correlated with individual duration of disease. Highly significant between groups differences emerged in total (tinnitus: -8.4 uV vs. controls: -3.8 uV), initial (-11.2 vs. -6.0 uV), and terminal CNV (-11.9 vs. -6.5 uV) demonstrating higher negative amplitudes in tinnitus patients. Habituation differed in total and terminal CNV, indicating missing habituation in tinnitus patients. Overall CNV (ϱ = -.365) and initial CNV (ϱ = -.529) showed a medium Spearman correlation with duration of disease. We conclude that the correlation between duration of tinnitus and the initial CNV amplitudes indicates an altered state of cortical excitability that can also be observed in more negative CNV-amplitudes in tinnitus patients. We assume that this state indicates a chronicity process in tinnitus disease.

Abstract
OBJECTIVE Nasal carriage of Staphylococcus aureus in patients with chronic rhinosinusitis with nasal polyps (NP) is hypothesized to have pathophysiological impact on the disease. Antimicrobial peptides (AMP), especially human beta-defensin-3 (hBD-3) and LL-37, are an important part of the multifactorial defence against microorganisms in barrier organs like the nasal mucosa. The interaction of S. aureus colonization and AMP in nasal secretions and mucosa of NP were investigated in this study. PATIENTS AND METHODS AMP were quantified in nasal secretions of 13 normal controls (NC) and 12 NP patients, each with and without S. aureus colonization, by ELISA. Immunohistochemistry was used to investigate the cellular sources of AMP in the nasal mucosa. To explore the AMP response of primary nasal epithelial cell cultures (NEC) towards S. aureus stimulation, a functional assay was established. RESULTS AMP could be demonstrated in nasal secretions of all groups without differences in hBD-3 concentrations comparing S. aureus carriers vs. non-carriers. In NC, higher LL-37 concentrations were observed in S. aureus colonized as compared to non-colonized patients. This effect was not detectable in NP patients. Epithelial cells, submucosal glands and cells of the connective tissue could be identified as sources of AMP by immunohistochemistry. An AMP response of NEC towards S. aureus stimulation was detected in all groups. CONCLUSION In NP patients, LL-37 response towards S. aureus colonization is disturbed while the ability of NEC to respond on S. aureus challenge is preserved. This deregulation of the nasal barrier could be involved in the multifactorial pathophysiology of NP.

Abstract
CONCLUSION The Harmony processor was found to be reliable, comfortable and offered a substantially increased battery life compared with the previous generation processor. No significant improvement in speech understanding with HiRes was demonstrated from objective measures, but the majority of subjects showed a clear subjective preference for the combination HiRes 120/Harmony processor. OBJECTIVES To evaluate experience with the Harmony™ sound processor, together with the HiRes 120 strategy. METHODS Postlingually deafened adults implanted with a CII or HiRes 90K were included and divided into three groups: (1) experienced users using the Platinum body-worn processor; (2) experienced users who had been using other processors; (3) new users with the Harmony processor from first fitting. The latter group entered a randomized crossover protocol where half were initially fitted with HiRes and half with HiRes 120. The initial strategy was used for 3 months and the alternative for a further 3 months. Speech perception tests and questionnaires were performed. RESULTS The study included 65 subjects. Implementing HiRes 120 was straightforward. The speech test group results did not show significant differences between HiRes and HiRes 120. However, the questionnaires showed significantly higher ratings for HiRes 120 in some instances. Subjects were highly satisfied with the Harmony processor.

Abstract
OBJECTIVES Granulomatosis with polyangiitis (GPA) frequently starts with an affection of the nasal and paranasal mucosa. Localised GPA of the nasal mucosa or persistent disease activity ('grumbling disease') is often encountered even under immunosuppressive therapy. Necessity for reconstructive surgery is common and careful scheduling to prevent failure and minimise revision rates is crucial. Therefore, reliable estimation of GPA activity in the upper airways using a score is mandatory for diagnosis, follow-up and scheduling reconstructive surgery. METHODS Fifty endoscopic, endonasal images of 45 patients with GPA were used. Twelve (4 German, 8 Mexican) experienced (n=7) and inexperienced (n=5) physicians assessed GPA-activity at two times (T1/T2) in dichotomy and in a grading approach (none, mild, moderate and high activity) using the novel ENT Activity Score (ENTAS). All documents were written in English. RESULTS Estimation of activity in dichotomy (none vs. mild/moderate/high): Cohen's Kappa (κ) for intra-rater reliability T1/T2 in inexperienced and experienced physicians was κ=0.58 (agreement 85%) and κ=0.72 (agreement 91%). The inter-rater reliability (Fleiss's κ) T1/T2 for inexperienced and experienced physicians was κ=0.62/κ=0.59 and κ=0.50/κ=0.58 respectively. Estimation of activity in grading approach (none, mild, moderate, high): for inexperienced physicians the intra-rater reliability T1/T2 was κ=0.67 (agreement 56%) and the inter-rater reliability at T1/T2 was κ=0.29 (intraclass correlation coefficient, ICC=0.69) and κ=0.27 (ICC=0.59). For experienced physicians the intra-rater reliability T1/T2 was κ=0.80 (agreement 67%) and the inter-rater reliability at T1 and T2 was κ=0.41 (ICC=0.77) and κ=0.39 (ICC=0.75) respectively. CONCLUSIONS Intra-rater reliability is high in decision in dichotomy and even in grading activity. There is no difference for experienced or inexperienced physicians. Inter-rater reliability is high in dichotomy, but low for activity grading. Thus, the ENTAS provides a reliable instrument for assessing, documenting and following GPA-related disease activity in the upper respiratory tract. The relationship of activity and following damage needs to be investigated in further studies.

Abstract
OBJECTIVE First, to investigate the overall efficacy and safety of rituximab (RTX) in refractory granulomatosis with polyangiitis (GPA) in a tertiary referral centre. Second, to compare the efficacy of RTX in granulomatous and vasculitic manifestations in GPA. PATIENTS AND METHODS This study comprised a retrospective, standardised data collection from all patients who received RTX for refractory Wegener's granulomatosis from 2002 to 2010. Patients were assessed by a standardised interdisciplinary diagnostic procedure (including ear, nose and throat and ophthalmology assessment, MRI, immunodiagnostics, B-cell levels and Birmingham Vasculitis Activity Score) and were treated by standardised therapeutic regimens according to available evidence. RESULTS 59 patients received 75 cycles of RTX. 9.3% achieved complete remission. A response was documented in 61.3% (improvement in 52%, unchanged disease activity in 9.3%), 26.7% had refractory disease. Birmingham Vasculitis Activity Score, disease extent index, erythrocyte sedimentation rate, C-reactive protein and prednisolone demand decreased significantly. All patients achieved B-cell depletion. Granulomatous manifestations such as orbital granuloma and pachymeningitis were more frequently refractory to RTX than vasculitis or other granulomatous manifestations. Thus, for example, complete remission/improvement was found in 89.2% of patients with renal disease and in only 44.4% of those with orbital masses (p=0.003). The relapse rate was 44.4% after a median period of 13.5 months. Adverse events occurred in 29%, pneumonia in 15% and death in 3%. CONCLUSION The overall response rate of refractory GPA to RTX was high (61.3% complete remission or improvement). Response rates of vasculitic manifestations were excellent; failure of response/progress was mostly due to granulomatous manifestations, especially orbital masses. Relapse rates were high (40%) despite maintenance treatment.

Abstract
This study investigates the incidence of clinically relevant asymmetry in bispectral index readings from different sides of the skull (using two monitors) during ear-nose-throat surgery in 42 adults and 46 children. A unilateral increase or decrease > 10% from baseline was defined as an 'asymmetry'. Asymmetry followed by movement after stimulation was defined as a 'clinically relevant asymmetry'. Asymmetry occurred in 39 out of 42 adults (93%) and in 20 out of 46 children (44%) during surgery and in 24 out of 42 adults (57%) and in 17 out of 46 children (37%) during recovery. Clinically relevant asymmetry was observed in 5 out of 42 adults (12%) and 6 out of 46 children (13%). The incidence of asymmetry was higher in adults during surgery (p = 0.0002). In conclusion, clinically relevant bispectral index asymmetry has been observed in > 10% of paediatric and adult anaesthesia and may have clinical implications.

Abstract
Several different methods can be applied for repairing total nasal defects. Most of them are based on some common principles and techniques widely accepted and adopted by experienced surgeons. We have been using most of these techniques during the past two decades, however modifying and refining them several times. Our observations and sometimes disappointing experiences led to a concept that has remained unchanged for the past 6 years. It comprises three regular operative steps and sometimes a fourth surgical intervention for repair and refinement. First stage: Reconstruction of the septum using a bipedicled composite septal pivot flap (SPF), of the intranasal lining (INL), and the cover being established by elevating a full-thickness paramedian forehead flap (PMFF). Second stage: Re-elevation of the PMFF, thinning of its layers, and reconstruction of the subsurface framework using autogenous rib cartilage. Third stage: Division of the pedicle and minor corrections. We have been using this technique presented here since 2004 in nine consecutive patients with subtotal to supratotal nasal defects. Seven cases have been repaired completely by now and can be evaluated carefully. With this technique, results have significantly improved and have been stable to date.

Abstract
Head and neck squamous cell carcinomas (HNSCC) represent the sixth largest group among all human malignancies. However, the exact molecular mechanisms inducing the genesis and the progression of metastasis in these tumors are poorly understood. The identification of molecular alterations involved in metastasis of HNSCC might influence the value of clinical diagnostics, impact therapy strategies and finally improve the prognosis of the patients. The purpose of this study was to identify clinically relevant alterations at the transcriptional and translational levels, when comparing metastatic (N+) and non-metastatic (N0) primary HNSCC. Three transcripts HERPUD1, SLPI and RAD51 were selected for further validation based on their association with carcinogenesis and metastasis. Quantitative real-time-PCR was performed to determine the mRNA expression levels. For subsequent confirmation of the results, immunohistochemistry was performed applying a monoclonal anti-SLPI antibody on 121 HNSCC tumor specimens (N0, n=40; N+, n=81). In metastatic primary cancer, SLPI mRNA showed 5.9-fold lower expression in comparison with non-metastatic primary cancer (p=0.0092). Immunohistochemical staining revealed a fold change of -1.79 between the N+ and the N0 group (p=0.0002). The results presented here clearly indicate the repression of SLPI, measurable on both, mRNA and protein levels in metastatic primary HNSCC as compared to non-metastatic HNSCC. Therefore, it can be assumed that SLPI might have a substantial protective effect on the metastasis process of HNSCC.

Abstract
OBJECTIVES Nasal S. aureus carrier rates are significantly higher in patients with Wegener's granulomatosis (WG) compared to healthy controls (HC), and nasal colonisation is a risk-factor for relapse. Antimicrobial peptides (AMP) are important defence molecules maintaining an intact barrier function. It is the aim of this study to see if there is a possible link between the nasal AMP pattern and S. aureus colonisation, a link which has not been investigated so far. METHODS ELISA was applied to quantify LL-37 and hBD-3 concentrations in nasal secretions (14 WG patients, 13 HC) with and without nasal S. aureus colonisation. Immunohistochemistry was used to detect the cellular sources of AMP in the nasal mucosa. Functional analyses of primary nasal epithelial cell cultures (NEC) of these groups stimulated with S. aureus were performed. RESULTS LL-37 was found in significantly higher concentrations in colonised individuals (WG: p=0.001; HC: p=0.014).Using immunohistochemistry, local cellular sources for AMP could be demonstrated. After stimulation with S. aureus, significantly higher concentrations of LL-37 and hBD-3 could be detected in the supernatant of NEC of WG patients (LL-37: p=0.001; hBD-3: p=0.001) and HC (LL-37: p=0.019; hBD-3: p=0.001). HBD-3 concentrations were significantly lower in the supernatant of stimulated NEC of WG patients compared to the NEC of HC (p=0.032), and the dynamic range of the hBD-3 answer was significantly smaller in WG compared to HC (p=0.016). CONCLUSIONS The dynamic response towards challenges with microbes is dysregulated in WG, and this might be one reason for higher S. aureus colonisation rates in WG.

Abstract
We report on a patient suffering from a mesenchymal tumour located at the antihelix. Histopathology of the tissue specimens derived from this lesion reported a myofibroblastic sarcoma, a rare tumour entity with a slight predominance of occurrence in the area of the head and neck. Grading of these tumours can be challenging since benign as well as malign phenotypes have been described. Therefore, beside complete resection of the lesion additional radiotherapy should be discussed individually.

Abstract
BACKGROUND There is a clear correlation between proliferative activity and the biological behavior of cancer, which might have an impact on the patients' prognosis and consequences for the individual therapy concept. REPP86 (restrictedly expressed proliferation-associated protein 86) is a proliferation-associated protein expressed in S-, G(2)- and M-phases of the cell cycle, regarded as a promising proliferation marker and has not yet been examined in squamous cell carcinoma of the larynx (SCCL). MATERIALS AND METHODS REPP86 was analyzed retrospectively in 104 SCCL using the monoclonal antibody Ki-S2. Proliferative activity was correlated with tumor stage, histopathological grading, patients' survival and the results we recently published on Ki-67 staining in SCCL. Median follow-up time was 47 months. RESULTS A significant correlation (p<0.05) between histopathological grading, N-status and proliferation activity was observed. The patient group consisting of low proliferating laryngeal cancer showed a statistically longer absolute (p<0.05) and relapse-free (p=0.001) 5-year survival time than the group with a high proliferating tumor. Compared to the Ki-67 staining results, the REPP86 antibody better predicts the relapse-free 5-year-survival. CONCLUSION Our results indicate that REPP86 staining of SCCL with Ki-S2 is a helpful prognostic indicator for SCCL and better predicts the relapse-free survival than Ki-67 staining in SCCL.

Abstract
ObjectiveTo identify patients with localised Wegener's granulomatosis (locWG) to assess whether it occurs as a long-term disease stage or phenotype and to characterise its outcome.MethodsPatients in a ‘localised stage’ with histological criteria compatible with WG and a follow-up period of ≥1 year were included. They were prospectively followed at the Vasculitis Center Schleswig-Holstein from 1989 to 2009 and the clinical manifestations, antineutrophil cytoplasmic autoantibodies (ANCA) status and damage were evaluated. Immunosuppression was adapted to disease activity and severity in a step-up regimen.ResultsOf 1024 patients with suspected WG, 99 were clinically diagnosed with locWG and 50 fulfilled the inclusion criteria (72% women, median age 43 years, 46% ANCA-positive). The median follow-up was 48 months. All achieved a response to treatment, 34% achieved complete remission, 1–4 relapses occurred in 46%, 5 (10%) had generalised disease (median 6 years after onset). ANCA status was not associated with relapse (p=0.98), transition to generalised disease (p=0.51) or refractory manifestations (p=0.60). 47% required cyclophosphamide for localised manifestations, 36% of them for pulmonary masses and 24% for orbital masses. 66% developed organ damage, mostly due to bony destruction or space obturation (28% saddle nose, 24% septal perforation, 10% orbital wall destruction). There were two deaths that were not related to WG.ConclusionThere is evidence that locWG is a long-term disease stage or phenotype (5% of all patients with WG), 46% of whom are ANCA-positive. LocWG is characterised by destructive and/or space-consuming lesions associated with high relapse rates (46%) and local damage.

Abstract
OBJECTIVES Nasal colonisation with Staphylococcus aureus (S. aureus) has been implicated in Wegener's granulomatosis (WG) disease activity. In this study, the frequency of nasal colonisation with S. aureus in WG was compared to healthy and disease control groups for the first time. Moreover, endonasal activity was correlated to colonisation. PATIENTS AND METHODS Nasal carriage of S. aureus of a well-defined group of 89 patients with WG was compared to 40 patients with chronic rhinosinusitis with nasal polyps (CRS), 35 patients with rheumatoid arthritis (RA), 50 hospital staff members and 25 subjects without regular hospital contact and correlation analysis of nasal carriage and endonasal activity of WG was performed. RESULTS WG patients showed significantly higher rates (72%) of nasal colonisation with S. aureus compared to CRS patients (28%) and healthy subjects without regular hospital contact (25%, 95%-CI), but not to RA patients (46%) and hospital staff members (58%). WG patients with nasal carriage of S. aureus had significantly higher endoscopically proven endonasal activity (p=0.01), significantly more often first manifestation of WG in the upper respiratory tract (p=0.02) and higher relapse-rates (p=0.052) than WG patients without such carriage. CONCLUSIONS Endonasal activity in WG is associated with higher nasal S. aureus colonisation rates and subsequent higher relapse rates. The higher frequency of S. aureus colonisation could be a consequence of a recently shown mucosal barrier defect in WG and facilitate chronic inflammation and granuloma formation in the upper respiratory tract.

Abstract
Necrotizing granulomatous inflammation of the upper respiratory tract is one of the hallmarks of Wegener's granulomatosis (WG), which may explain the reason for olfactory dysfunction in WG. However, a systematic analysis using modem olfactory testing tools has not been performed and potential causes of dysfunction at different levels of olfactory information processing remain obscure so far. In this study a group of 76 WG-patients was examined with sniffin'sticks screening 12, odour threshold (T)/discrimination (D)/identification (I) TDI-score, active anterior rhinomanometry and a standardized questionnaire for olfactory function. WG-patients were aware of their olfactory dysfunction, as proven by psychophysiological test results. An altered olfactory function was significantly correlated to local administration of mupirocin and to the time interval between first diagnosis and study entry. None of the other variables had a statistical significant effect on the olfactory dysfunction.

Abstract
Granuloma formation is a key pathologic finding in two of the anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitides: Wegener's granulomatosis (WG) and Churg-Strauss syndrome (CSS). So far, no animal models have been established convincingly reproducing both vasculitic and granulomatous features typical of WG and CSS. In biopsies, granulomatous lesions are found both at distant extravascular sites and in the vicinity of inflamed vessels, e.g. in the lung. Intriguingly, WG-granulomata appear to display features of tertiary lymphoid tissue. Cartilaginous and osseous destruction is caused by granulomatous inflammation invading adjacent tissues. Rhinosinusitis is regularly encountered in WG and CSS. Septal perforation, saddle nose deformity, middle and inner ear symptoms, and granulomatous invasion of the palate, orbita, meninges, or the pituitary gland may complicate WG. Both common (e.g. FCGR3B copy number) and distinct (e.g. HLA-DP, IL-10.2) genetic factors have been identified in AAV potentially favouring inflammation and autoimmunity. The HLA-DPB1/RING1/RXRB region constitutes a quantitative trait locus for ANCA-positive WG with the strongest association to be reported up to now. A profound alteration of the T-cell response including Th1 and Th17 responses, anomalously NK-receptor-expressing 'NK-like' T cells, and dysfunctional regulatory T cells could facilitate and sustain granuloma formation and autoimmunity.

Abstract
Wegener's granulomatosis, Churg-Strauss syndrome and analgesics intolerance syndrome with polyps demonstrate non-specific manifestations in the head and neck region. These symptoms can often lead to early diagnosis and initiation of the correct therapy. However, symptoms are often ambiguous and many rare differential diagnoses must be borne in mind. This clinical picture presents a challenge for the otorhinolaryngologist, who is commonly the first contacted physician. Diagnostics and therapy have to be carried out in an interdisciplinary approach between rheumatologist, pulmonologist, pathologist, radiologist, ophthalmologist, infection specialist and nephrologist. Despite significant scientific and therapeutic advances, these diseases remain incurable. In recent decades they have lost their life-threatening character (Wegener's granulomatosis) and are now chronically relapsing diseases. Their aetiology, however, is still unclear and treatment leads to a wide spectrum of undesirable effects. Research work is needed to advance diagnostics and therapy in this field. Recent research aspects are presented in this article.

Abstract
OBJECTIVE The pathogenesis of granulomatous inflammation in the respiratory tract and autoimmunity in Wegener granulomatosis (WG) are poorly understood. Since mucociliar clearance represents the first major line of defence in the respiratory tract and its breakdown facilitates chronic inflammation, we investigated ciliary beat frequency (CBF) in WG. METHODS Nasal epithelial cells were obtained from 30 patients with WG with involvement of the upper respiratory tract, 12 patients with other inflammatory rheumatic disease and 10 healthy controls. CBF was measured at 5 and 24 h after collection. RESULTS were correlated with clinical data. Results: CBF was significantly reduced in WG compared to disease and healthy controls after 5 and 24 h. In WG, CBF almost stagnated after 24 h. Reduction of CBF correlated with the cumulative number of immunosuppressive agents in WG, but not in disease controls. No correlation was found between CBF impairment and cyclophosphamide levels, disease extent, disease activity, disease duration, serological and microbiological findings, or inflammation markers. CONCLUSION CBF is severely impaired in WG, potentially influenced by immunosuppressive treatment. To what extent CBF impairment and subsequent barrier dysfunction are caused by other factors still has to be elucidated. Supportive measures to improve mucociliary clearance should be discussed in patients with WG.

Abstract
Lysyl oxidases are a family of five copper-dependent amine oxidases including LOX, LOXL, LOXL2, LOXL3 and LOXL4. LOX and LOXL are essential for the assembly and maintenance of extracellular matrixes. LOXL2, LOXL3 and LOXL4, secreted and active enzymes, were also noted in association with diverse tumor types. We have recently reported overexpression of the LOXL4 mRNA and protein and a close relation of LOXL4 with the pathogenesis of head and neck squamous cell carcinomas (HNSCC). In this study, we analyzed the organization of the LOXL4 gene and addressed the regulatory mechanisms responsible for the overexpression. We demonstrated de novo transcription of the LOXL4 gene in HNSCC, but not in normal squamous epithelial cells. Analysis of the consecutive promoter region spanning positions -960 to -1 identified binding sites for several transcription factors. Promoter constructs containing selected specific promoter regions and consensus binding sites exhibited significantly increased reporter gene activity in HNSCC cells, but not in normal epithelial cells in transient coexpression experiments. The activity profiles of some of these constructs were similar in both cell types indicating that elements of the basic transcriptional regulatory mechanisms remained intact in HNSCC cells. DNA-binding experiments demonstrated that nuclear extracts from HNSCC cells have increased binding activity to the TATA (-25) and the SP1 (-181) sites compared to normal epithelial cells, suggesting that these transcription factors are involved in the upregulation of LOXL4 gene expression in HNSCC.
