RESUMEN
BACKGROUND: The active transcutaneous, partially implantable osseointegrated bone conduction system Cochlear™ Osia® (Cochlear, Sydney, Australia) has been approved for use in German-speaking countries since April 2021. The Osia is indicated for patients either having conductive (CHL) or mixed hearing loss (MHL) with an average bone conduction (BC) hearing loss of 55â¯dB HL or less, or having single-sided deafness (SSD). OBJECTIVES: The aim of this retrospective study was to investigate the prediction of postoperative speech recognition with Osia® and to evaluate the speech recognition of patients with MHL and in particular an aided dynamic range of less than 30â¯dB with Osia®. MATERIALS AND METHODS: Between 2017 and 2022, 29 adult patients were fitted with the Osia®, 10 patients (11 ears) with CHL and 19 patients (25 ears) with MHL. MHL was subdivided into two groups: MHLI with four-frequency pure-tone average in BC (BC-4PTA) ≥â¯20â¯dB HL and <â¯40â¯dB HL (nâ¯= 15 patients; 20 ears) vs. MHL-II with BC-4PTA ≥â¯40â¯dB HL (nâ¯= 4 patients; 5 ears). All patients tested a bone conduction hearing device on a softband preoperatively. Speech intelligibility in quiet was assessed preoperatively using the Freiburg monosyllabic test in unaided condition, with the trial BCHD preoperatively and with Osia® postoperatively with Osia®. The maximum word recognition score (mWRS) unaided and the word recognition score (WRS) with the test system at 65â¯dB SPL were correlated with the postoperative WRS with Osia® at 65â¯dB SPL. RESULTS: Preoperative prediction of postoperative outcome with Osia® was better using the mWRS than by the WRS at 65â¯dB SPL with the test device on the softband. Postoperative WRS was most predictive for patients with CHL and less predictable for patients with mixed hearing loss with BC-4PTA ≥â¯40â¯dB HL. For the test device on a softband, the achievable outcome tended to a minimum, with the mWRS tending to predict the realistically achievable outcome. CONCLUSION: Osia® can be used for the treatment of CHL and MHL within the indication limits. The average preoperative bone conduction hearing threshold also provides an approximate estimate of the postoperative WRS with Osia®, for which the most accurate prediction is obtained using the preoperative mWRS. Prediction accuracy decreases from a BC-4PTA of ≥â¯40â¯dB HL.

MHL was subdivided into two groups: MHLI with four-frequency pure-tone average in BC (BC-4PTA) ≥â¯20â¯dB HL and <â¯40â¯dB HL (nâ¯= 15 patients; 20 ears) vs. MHL-II with BC-4PTA ≥â¯40â¯dB HL (nâ¯= 4 patients; 5 ears). All patients tested a bone conduction hearing device on a softband preoperatively. Speech intelligibility in quiet was assessed preoperatively using the Freiburg monosyllabic test unaided and with the test system and postoperatively with Osia. The maximum monosyllabic score (mEV) unaided and the monosyllabic score with the test system at 65â¯dB SPL were correlated with the postoperative monosyllabic score with Osia at 65â¯dB SPL. RESULTS: Preoperative prediction of postoperative outcome with Osia was better using the mEV than the EV at 65â¯dB SPL with the test device on the softband. Postoperative EV was most predictive for patients with CHL and least predictive for patients with mixed hearing loss with 4PTA BC ≥â¯40â¯dB HL. For the test device at softband, results tended to show the minimum achievable outcome and the mEV tended to predict the realistically achievable outcome. CONCLUSION: Osia can be used for the treatment of CHL and MHL within the indication limits. The average preoperative bone conduction hearing threshold also provides an approximate estimate of the postoperative EV with Osia, for which the most accurate prediction is obtained using the preoperative mEV. Prediction accuracy decreases from a BC-4PTA of ≥â¯40â¯dB.
RESUMEN
PURPOSE: We investigated the long-term results of cochlear implant (CI) recipients with asymmetric hearing loss (AHL) or single-sided deafness (SSD). We focused on wearing behavior, audiometric hearing rehabilitation, and subjective benefits of the CI. CI is expected to improve audiological results, subjective hearing perception, and tinnitus burden. METHODS: Speech recognition in background noise and sound localization were assessed preoperatively and after at least six years of CI experience. Validated questionnaires determined the subjective benefit of CI use and the subjective evaluation of tinnitus. RESULTS: Over 80% of the included AHL and SSD CI recipients used their CI between 6 and 10 h daily; four subjects with SSD were non-users. Speech recognition in background noise and sound localization improved significantly compared with the unaided preoperative situation. Additionally, CI improved subjective speech intelligibility and spatial hearing impression while reducing tinnitus burden. CONCLUSION: Subjects with AHL and SSD benefit from CI, subjectively and audiologically. Cochlear implant is a successful long-term treatment for AHL and SSD.

PURPOSE: The purpose of this retrospective study was to investigate the outcome and critical age of cochlear implantation in congenital single-sided deafness (SSD). METHODS: 11 children with congenital SSD were implanted with a cochlear implant (CI). Auditory performance was measured through the results of speech discrimination, subjective assessment by the Categories of auditory performance (CAP) score, the Speech, Spatial and Qualities scale questionnaire (SSQ) and the German version of the IOI-HA [Internationales Inventar zur Evaluation von Hörgeräten (IIEH, version for CI)]. RESULTS: Long-term follow-up [median: 3 years and 5 months (3;5 years)] revealed that nine children use their CI (> 8 h/day) and two became nonusers. In children aged below 3;2 years at surgery, there was a substantial long-term increase in speech discrimination and subjective benefit. Children over 4;4 years of age at CI surgery improved partially in audiological/subjective measurements. Among children above 5 years, the SSQ score did not improve despite further slight improvement in speech discrimination long-term. CONCLUSION: Our data suggest a critical age for CI surgery below 3 years in children with congenital SSD for successful hearing rehabilitation. It is mandatory to identify children with SSD as early as bilaterally deaf children.

PURPOSE: This study analyses data logs in order to investigate the usage pattern of cochlear implant (CI) recipients with single-sided deafness (SSD-CI) and bilaterally deaf, uni- or bilaterally implanted CI recipients (Uni-CI and Bil-CI). Data logging is available from SCAN, an automated auditory scene classifier which categorizes auditory input into 6 listening environments. METHODS: CI usage data were retrospectively available from data logs of 206 CI recipients using the Nucleus 6 system obtained between January 2013 and June 2015. For all recipients, we analysed time on air and time spent in the listening environments. For statistical analysis, we matched the CI recipients according to age and duration of CI experience and classified them into 4 age groups. RESULTS: SSD-CI showed a similar time on air compared to Uni- and Bil-CI. Usage behaviour of SSD-CI was comparable to Uni- and Bil-CI regarding exposure to music, speech in quiet and speech in noise. With increasing age, exposure to quiet increased and exposure to music decreased across all CI recipient groups in relation to time on air. CONCLUSION: In total, the CI usage pattern of SSD-CI is comparable for the majority of listening environments and age groups to that of Uni- and Bil-CI. The results of our study show that SSD-CI benefit equally from CI implantation.

PURPOSE: Surgical management, including the extent of surgery, for patients with parotid malignant tumors has been challenging. The aims of the present study were to identify the factors associated with survival, estimate the incidence of occult nodal and intraglandular metastases, and determine the predictive influence on overall and disease-free survival, with consideration of the surgical extent. PATIENTS AND METHODS: We implemented a retrospective cohort study and identified incident cases with parotid malignant tumors from 2003 to 2016 at a single quaternary medical care and cancer center. A medical record analysis was performed retrospectively of the patient and histopathologic data. The predictor variables were age; tumor grade; T stage; N stage; facial nerve palsy; perineural, vascular, and lymphovascular invasion; completion parotidectomy; elective neck dissection; and pN0 versus pN+. Overall and disease-free survival were evaluated as primary and secondary outcome variables. Data analysis was performed as a time-to-event analysis (Kaplan-Meier method). RESULTS: A total of 102 patients with parotid carcinoma had undergone surgery from 2003 to 2016 at the University Hospital Freiburg, Germany; 69 patients had undergone completion parotidectomy (total, 36; radical, 33). A total of 13 patients had occult intraparotideal lymph node metastases after elective completion parotidectomy. All the patients who had undergone elective neck dissection and clinically had had no nodal involvement (cN0) had had no pathologic lymph node metastases found (pN0). However, the predictive factors for cervical nodal involvement were high-grade tumors, locally advanced tumors (cT3-cT4), and the presence of intraparotideal nodal metastases. CONCLUSIONS: The rate of occult cervical metastases in the present study was surprisingly low (0%). However, owing to the various predictive factors, elective neck dissection should be performed for high-grade or locally advanced (stage T3-T4) parotid malignoma. Moreover, we highly recommend performing completion parotidectomy for all high-grade tumors and also for locally advanced (stage T3-T4) low-grade tumors, owing to the >12% of occult intraparotideal metastases found in the present study.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a mainly type-2-driven inflammatory disease that is often refractory to medical and surgical treatment and characterized by a high rate of recurrence. Monoclonal antibodies have been approved for severe refractory CRSwNP. Randomized controlled trials (RCT) have shown significant improvement in objective and subjective parameters. The results of these RCTs cannot necessarily be transferred to daily routine. The purpose of this retrospective study is to evaluate the treatment effects of biologics in patients with CRSwNP in a real-life setting. Patients treated with one of the approved biologics since July 2020 with at least 6 months follow-up were included in the study. Changes in SNOT-22 and nasal polyp score (NPS), as well as subjective change in sense of smell, number of sinus surgeries prior to and during treatment, comorbidities, discontinuation or change of monoclonal antibody and adverse events were evaluated. Thirty-three patients were included in this study. The mean SNOT-22 score and NPS improved significantly. The subjective assessment of sense of smell showed an improvement in 81.8% of patients. The monoclonal antibody had to be changed in seven patients. No severe adverse events occurred during the initiation of the treatment and follow-up. Biologics can be a treatment option in patients with severe refractory CRSwNP, showing significant improvements in quality of life, symptoms and polyp scores in randomized controlled trials and clinical routine with rare complications. Further research is needed to evaluate possible biomarkers, interdose interval prolongation and long-term safety.
