RESUMO
PURPOSE: The incidence of salivary duct carcinoma (SDC) seems to be underestimated due to inaccurate classification. Further, the frequency of SDC patients with targeted therapy options according to current guidelines is unclear. Therefore, this study aimed at (a) describing the proportion of SDC among salivary gland carcinoma (SGC) before and after reclassification of cases initially classified as adenocarcinoma, not otherwise specified (ANOS); and (b) quantifying the frequency of SDC patients with targeted therapy options. METHODS: All patients with SDC or ANOS treated in a tertiary care center between 1996 and 2023 were identified. Histopathological diagnosis was verified for patients primarily diagnosed with SDC and reviewed for patients initially diagnosed with ANOS. Clinical data for SDC patients were retrieved from clinical charts. Immunohistochemical (IHC) androgen receptor (AR) and HER2 staining was performed. RESULTS: Among 46 SDC, 34 were primarily diagnosed as SDC and 12 had initially been classified as ANOS. The proportion of SDC among SGC was 12.1% and was rising when comparing the time periods 2000-2015 (7.1-11.5%) versus 2016-2023 (15.4-18.1%). Nuclear AR staining in > 70% of tumor cells was found in 56.8% and HER2 positivity (IHC 3 +) in 36.4% of cases. 70.5% of patients showed AR staining in > 70% of tumor cells and/or HER2 positivity and therefore at least one molecular target. 5-year overall and disease-free survival (DFS) were 62.8% and 41.0%. Multivariate Cox regression revealed positive resection margins (HR = 4.0, p = 0.03) as independent negative predictor for DFS. CONCLUSIONS: The results suggest a rising SDC incidence and show that the extent of the AR and HER2 expression allows for targeted therapy in most SDC cases.

PURPOSE: We hypothesized that using a 3D-exoscope (3Dex) in microlaryngoscopic phonosurgery is non-inferior to using a standard operating microscope (OM). To compare the above, we utilized a 3Dex and an OM for microlaryngoscopic vocal fold augmentation with autologous fat in patients with glottic insufficiency and compared the procedure itself and the long-term impact of vocal fold augmentation on subjective and objective voice parameters in both groups. METHODS: 36 patients with glottic insufficiency received microlaryngoscopic laryngeal augmentation with autologous fat. A 3Dex was utilized in 24 cases for visualization and compared to twelve cases in which an OM was used. Voice parameters were evaluated over a period of twelve months. RESULTS: Comparison of operation time and voice parameters between the 3Dex and OM groups did not reveal significant differences. Significant improvement of mean voice quality in all parameters excluding roughness was observed at 3 and 6 months followed then by a slight decrease of voice quality parameters between the 6 and 12 months interval in both groups. CONCLUSION: Our findings indicate no difference concerning operation time and outcome between the use of a 3Dex and an OM in phonosurgery. Our results highlight a significant voice improvement after vocal fold augmentation with autologous fat in glottic insufficiency mediated dysphonia. The smaller viewing system, better ergonomics for the primary surgeon and the assistant and a direct view for the entire surgical team make a 3Dex an interesting alternative for visualization in microlaryngoscopic phonosurgery.

OBJECTIVE: The COVID-19 pandemic has had a profound impact on the healthcare system and medical education. In this publication, the influence of the pandemic on the education of physicians active in Head and Neck oncology was examined using a survey. METHODS: A survey comprising 53 questions was conducted to gather data on work settings, daily activities, team events, and educational aspects during the pandemic. A total of 497 oncologists participated, including 131 individuals working in the field of Head and Neck oncology. This subgroup consisted of 99 (75.6%) radiation oncologists, 10 (7.6%) maxillofacial specialists, and 22 (16.8%) otolaryngologists. RESULTS: Nearly half of the participants reported experiencing increased clinical burden, which resulted in reduced engagement in scientific activities. Digital platforms became the predominant mode of continuing education, albeit with reduced accessibility. The pandemic significantly impacted clinical training that involved direct patient interaction. On the other hand, positive effects were observed in terms of cost and availability for external educational events such as conferences. CONCLUSION: The findings highlight the detrimental effects of the COVID-19 pandemic on various aspects of medical education. While digitalization has accelerated in response, many physicians expressed a lack of professional interaction. Developing alternative digital learning platforms can provide a means to better cope with similar situations in the future. However, the importance of personal contact with colleagues and supervisors should not be overlooked when considering the quality of teaching.

BACKGROUND: The ORL-App, a smartphone app for further education and training for ORL doctors and those interested in ORL, complements existing offers in medical education and training. The principle of game-based e-learning can open up new perspectives in times of digitalisation and pandemic. The heart of the app is a large ORL quiz, in which app users compete against each other. This paper analyses the performance of app users in the quiz module, taking into account the questions' categories and the users' level of education. MATERIAL AND METHODS: Retrospectively, an evaluation of the quiz questions was carried out for the first 24 months after the introduction of the app. There were 3593 different questions to choose from in 16 different categories. Based on the level of training, a distinction was made between doctors in further training, specialists, senior physicians, chief physicians and professors in the field of ORL. In addition, data on students and non-medical staff were available. RESULTS: There was a significant difference in the level of knowledge of the users considering the level of training. The group of doctors in further training (n = 1013) represented the largest group, with an average of 244 questions per user and 65.1% of the questions answered correctly. They thus achieved a significantly better answer rate than the group of specialists (n = 566), who were able to answer 61.0 % of the questions correctly. CONCLUSION: The game-based form of training through the quiz-part of the ORL-App seems to be particularly attractive for doctors in further training. In addition, this user group achieved better answer rates than the specialists.

BACKGROUND: Residents of ENT were asked about their situation in residency. A good and well structured training is the key for an attractive residency. METHODS: Between April 25-August 1, 2019, 691 residents registered with the German Society of Otorhinolaryngology, Head- and Neck Surgery ENT society were invited to anonymously participate in an online survey using SurveyMonkey® on the situation of the education in ENT and their working conditions. 25 of 80 questions were asked on the topics of structure and quality of the education in residency. RESULTS: The response rate was 36â% (nâ=â249). The participants attested their further training an average result. Mainly they see deficits in the further education and training structure and culture with a desire for improved feedback and improved surgical training. Participants were more dissatisfied with advanced further training time, regardless of ownership of the institution and level of care. CONCLUSIONS: The survey proposes concrete advice for improvement of ENT medical training in Germany. Suggestions for improvement are further development of the associated training and continuing education programs in cooperation with professional associations, structured feedback and supervision as well as transparent rotation plans and reliable working conditions.

INTRODUCTION: An increased psychosocial workload can have an negative impact on health. An effective way to record this is the effort reward imbalance model postulated by Siegrist. Values on this topic from ENT residents are missing, which is why the concept and corresponding questions were included in the survey on the current situation in further education. MATERIAL AND METHODS: An online survey on the current situation of the ENT residency including the recording of psychosocial workload was developed by ENT physicians on the basis of a well-known questionnaire of colleagues of the Alliance of Young Physicians. The short version of the validated questionnaire on the effort reward imbalance model according to Siegrist with 16 items was used. An online survey was carried out addressing all ENT residents in Germany known to the German society of Oto-Rhino-Laryngology, Head and Neck surgery. The survey was sent by e-mail and was available from April 1st to July 31st in 2019. RESULTS: 92,3â% of the participants had an effort-reward imbalance. The mean value of effort reward imbalance was 1.57â± 0.43, adjusted 2.16â±â1.36. The effort scale was 10.71â±â1.40 (3-12), adjusted 85.72â±â15.52, reward scale 16.58â±â2.86 (7-28), adjusted 45.61â±â13.63, over commitment 17â±â3.37, adjusted 61.14â±â18.73. A high effort reward imbalance had positive significant correlations with regard to the duration of residency, the number of working hours per week and the number of duty hours per month. CONCLUSION: The effort and reward imbalance is comparable to other specialty physicians in residency. It is related to working hours, services and the progress of training. It can be improved through personal initiative and could be supplemented with the support of the hospital's internal stakeholders.

OBJECTIVE: Interactive e-learning-platforms may replace the classical textbook in the future. Such media have the possible advantage of including video and audio files in a more comprehensive way, but ENT-specific platforms do not currently exist. So far, the actual needs and wishes of ENT residents are unclear and may be affected by the so called digital revolution. MATERIAL AND METHODS: An online survey was carried out addressing all ENT residents in Germany known to the German society of oto-rhino-laryngology, head and neck surgery. A 17-items survey was developed by ENT doctors receiving and providing training and distributed by e-mail. The survey was available to answer in April and May 2019. RESULTS: A total of 150 out of 671 ENT specialists and residents took part in the study. Of these, 80â% were residents and 20â% were ENT specialists. 63-80â% of the respondents already use online media in general at work, in preparation for the ENT specialist examination, for training purposes and for support as a clinician. 92-95â% of the participants indicated the willingness to use an interactive platform for their ENT specialist examination preparation and further training. On average, e-learning media are used by the responders to prepare for the ENT specialist examination or in clinical everyday life and for further training 108 or 130âmin/week. The desire for surgical instruction videos is also very high. CONCLUSION: There is a high demand for a structured e-learning-platform especially for ENT. An interactive e-learning-platform would ensure, supplement and support qualified education and training.

BACKGROUND: A parotid abscess (PA) is a complication of an acute bacterial parotitis with a potentially life-threatening course. To date, data on the diagnosis and therapy of PA is sparse and mostly consists of case reports or case series. Therefore, this study aimed at comprehensively analyzing the microbiological spectrum and the therapeutic management in a bi-institutional setting. METHODS: A retrospective clinical chart review was performed to identify all patients surgically treated for PA at two tertiary care centers in Germany. Data on demographics, clinical management and microbiological data including species identification, pathogenicity, type of antibiotic therapy, adjustment of antibiotics, antibiotic sensitivity testing, and smear test results were extracted. Intervention-related variables and etiology were analyzed for their statistical association with outcome variables. RESULTS: Overall, 85 patients were included. Most patients (92.9%) underwent surgical incision. Around half of the patients (45.9%) were treated under local anesthesia. No facial nerve palsy was observed. The most frequently detected pathogens were Streptococci (n = 23), followed by Staphylococcus aureus (n = 6) including one case of methicillin-resistant Staphylococcus aureus. Most patients (68.2%) received an aminopenicillin ± beta-lactamase inhibitor as empiric antibiotic therapy. In 6 cases the antibiotic therapy was modified after receiving the antibiogram. Four patients (5.2%) presented with recurrent PA. Etiology was idiopathic (42.4%), followed by tumorous (12.9%), obstructive, and immunosuppressive (each 11.8%). Patients with a dental focus (p = 0.007) had a longer duration of hospitalization. CONCLUSION: The results show that the surgical therapy of PA under local anesthesia is safe. A dental examination should routinely be performed to rule out a dental focus. Obtaining a microbiological specimen in order to modify antibiotic therapy if necessary and a histopathological specimen to rule out a tumorous etiology is obligate.

OBJECTIVE: The aim of this study was to evaluate the quality and the educational content of YouTube videos showing parotidectomy. METHODS: We searched for videos displaying parotidectomy on YouTube. To rate parotidectomy videos, we introduced the "Instructional Videos in Otorhinolaryngology by YO-IFOS (IVORY)-grading-system (GS)" derived from the IVORY Guidelines, which pose established consensus recommendations for the production of educational surgical videos in otolaryngology. The videos were rated using the IVORY-GS, and the total score was tested for statistical association with views, likes, likes/dislikes-ratio, age, and length of the videos for validation of the IVORY-GS. RESULTS: Overall, 50 parotidectomy videos were identified. Sixty-eight (68%) of the videos showed a superficial parotidectomy. The mean IVORY-GS total score was 24.9 (out of a maximum of 44 points). Video education quality was rated as moderate in 22% and high in 4%. There was a statistically significant correlation between the total score and the number of views (p = 0.03), the total score and the number of likes (p < 0.01), and the total score and the likes/dislikes ratio (p < 0.01). A higher total score was a significant predictor of more likes (p = 0.01) and a higher likes/dislikes ratio (p < 0.01). CONCLUSION: Our modification of the IVORY Guidelines is otolaryngology-specific, suitable, and recommended to evaluate parotidectomy videos. To date, most videos are of poor educational quality. Future efforts in otolaryngology surgical video education could focus on the establishment of an online video platform. LEVEL OF EVIDENCE: NA Laryngoscope, 133:2631-2637, 2023.

Many locally advanced and metastatic salivary gland carcinomas (SGC) lack therapeutic targets. Enfortumab vedotin, an antibody-drug conjugate binding to Nectin-4, recently gained FDA approval for third-line urothelial carcinoma. Therefore, the aim of this study was to assess the expression of Nectin-4 in primary SGC and corresponding lymph node metastases and to correlate it with clinicopathological data. Immunohistochemical staining for Nectin-4 was performed for patients who had undergone surgery with curative intent for primary SGC of the parotid or submandibular gland in a tertiary referral center between 1990 and 2019. One hundred twenty-two primary SGC and twenty corresponding lymph node metastases were included. Nectin-4 was expressed in 80.3% of primary SGC with a mean Histo(H-)score of 61.2 and in 90.0% of lymph node metastases with a mean H-score of 75.6. A moderate or high Nectin-4 expression was found in 25.9% of salivary duct carcinomas (SaDu) and in 30.7% of adenoid cystic carcinomas (ACC). SaDu patients with a lower T-stage (p = 0.04), no loco-regional lymph node metastases (p = 0.049), no vascular invasion (p = 0.04), and no perineural spread (p = 0.03) showed a significantly higher mean Nectin-4 H-score. There was a statistical tendency towards a more favorable disease-free survival among SaDu patients with a higher Nectin-4 expression (p = 0.09). Nectin-4 is expressed in SGC and therefore represents a potential therapeutic target, especially in entities with a high rate of local recurrence and metastatic spread such as SaDu and ACC.

INTRODUCTION: Obstructive sleep apnea syndrome (OSAS) is the most common sleep disorder in humans. Although OSAS is clearly related to arterial hypertension, coronary artery disease, and heart failure, it remains unknown through which pathomechanisms OSAS influences cardiovascular health. Recent research has pinpointed long non-coding RNAs (lncRNA) as important molecular mediators of various cardiovascular pathologies. In this study, we have identified the lncRNA MRPL20-AS1 to be affected by OSAS in patients as well as by hypoxia in vitro. METHODS AND RESULTS: A transcriptomic analysis was performed on peripheral blood from four patients with severe OSAS taken after one night of polygraphic assessment. We found that three lncRNAs were significantly dysregulated, of which MRPL20-AS1 was the most significant. In a larger cohort of 22 OSAS patients, MRPL20-AS1 was inversely correlated with the apnea-hypopnea index (AHI). This indicates that OSAS patients with higher AHI levels and therefore more severe OSAS had lower levels of MRPL20-AS1 in the blood. The results were recapitulated in vitro by subjecting endothelial cells to hypoxia. In these experiments, hypoxia led to a significant downregulation of MRPL20-AS1 in endothelial cells. CONCLUSION: MRPL20-AS1 may serve as a useful tool to identify patients suffering from severe OSAS and further research should be done to evaluate the therapeutic potential of MRPL20-AS1 as a target to counteract the cardiovascular effects of OSAS.

BACKGROUND: Delayed complications after cochlear implant (CI) surgery can result in the need for revision surgery. Temporal bone computed tomography (tCT) is frequently used in the diagnostic work-up for these patients. AIMS/OBJECTIVES: We aimed to test for the value of tCT in delayed complications after CI surgery. MATERIAL AND METHODS: Retrospective chart review including all patients with CI who were consecutively enrolled in our academic tertiary care centre and received a tCT due to delayed complications between January 2008 and December 2017. RESULTS: A total of 85 patients with a mean age of 28 years at CI surgery were identified. Mean time between CI and tCT was 4.3 years. Reasons for performance of tCT were device malfunction (20%), cephalgia (20%), scalp hematoma/seroma (15.3%), device failure (11.8%), vertigo (10.6%), local infection (7.1%), trauma (5.9%), meningism (3.5%), tinnitus (3.5%) and facial palsy (2.4%). No abnormalities in tCT were detected in 82.4%. However, an abnormal tCT was a predictor for surgical therapy (p < .001). CONCLUSIONS AND SIGNIFICANCE: We recommend the performance of tCT in CI patients with delayed complications to identify or rule out pathology in order to choose the most ideal and relevant individual treatment.

OBJECTIVE: The involvement of the dura is a rare yet potentially life-threatening complication during cholesteatoma surgery. Thus, the knowledge about treatment and consequences of this issue is of great importance to every ear surgeon. METHODS: This retrospective study analyzed the dura involvement with regard to the type of defect, reconstruction method used, and the post-operative complications of 1291 pediatric and adult cholesteatoma surgeries performed at an academic tertiary care center over a twelve-year period. RESULTS: From a total of 1291 cholesteatoma surgeries, we identified 84 patients (6.5%) with dura involvement intraoperatively, most of them adult patients. The majority of the reported cases were bony defects and exposed dura without CSF leakage (79.73%, 67 out of 84). In 14.28% of the cases (12 out of 84) a meningo(encephalo)cele or dura defect with liquorrhea were detected. In 30 surgeries (35.7%, 30 out of 84) no reconstruction of the lateral skull base was considered necessary. The most common material used for reconstruction was conchal cartilage (25.0%, 21 out of 84), followed by polydioxanone (PDS)-foil (11.9%, 10 out of 84), bone pâté (9.5%, 8 out of 84) and a combination of materials (17.9%, 15 out of 84). Revision surgery of the reconstruction was necessary in 16.7% (14 out of 84) of the cases. Long-term evaluation (mean of 19.3 months) showed no complication related to the skull base defect. CONCLUSION: During cholesteatoma surgery, bony and dura defects can be managed effectively, with good long-term reliability. No intracranial or mastoidal complications are expected.

BACKGROUND: The purpose of this study was to evaluate the occurrence of hypoesthesia after superficial parotidectomy depending on preservation of posterior branch of the great auricular nerve (GAN). METHODS: This prospective, controlled, double blind, multicenter trial included 130 patients. The posterior branch was preserved in 93 patients (GAN group), and ligated in 33 patients (non-GAN group). In 4 patients, GAN status was unknown. Included patients underwent sensory testing (TouchTest) and subjective evaluation at 6, 12, and 24 months after surgery. RESULTS: Better improvement of sensation was present in the GAN group. After 12 months, 59% of the patients in the GAN-group showed positive test results in the lobule, versus 24% of the non-GAN group (p = .013). Additionally, after 24 months, 71% of the patients in the GAN-group showed a positive test in the antitragus, versus 31% in the non-GAN group (p = .045). Hypoesthesia equally limited quality of life in both groups (all p > .05). CONCLUSION: Preservation of the posterior branch of the GAN led to significantly better improvement of sensation in the lobule and antitragus, and should be recommended during parotidectomy. © 2017 Wiley Periodicals, Inc.
