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 The new active transcutaneous partially implantable osseointegrated system Cochlear™ Osia® System is indicated in case of conductive or mixed hearing loss (CHL/MHL) with a maximum average bone conduction hearing loss of 55 dB, or in single-sided deafness (SSD). The implant directly stimulates the bone via a piezoelectric transducer and is directed by an external sound processor. We conducted a monocentric retrospective longitudinal within-subject clinical study at our tertiary academic referral center. The aim was to investigate long-term data (2017–2021) on audiological outcomes and hearing-related quality of life for the Osia system. Methods Between 2017 and 2020, 22 adults (18: CHL/MHL; 3: SSD) were implanted with the Osia100 implant; seven received bilateral implants. As of 10/2020, the sound processor was upgraded to Osia 2. Results Mean Osia system use by 04/2021 was 30.9 ± 8.6 months (range 17–40 months). Unaided bone conduction thresholds were unchanged postoperatively. One patient had to be explanted because of prolonged wound infection. Aided hearing thresholds were significantly lower compared to the unaided thresholds preoperatively, along with a marked increase in speech recognition in quiet. Speech processor upgrade resulted in a stable benefit. Patients with CHL/MHL and SSD showed a similar improvement in self-rated hearing performance revealed by SSQ, APHAB, and HUI questionnaires. Conclusion The Osia system is a safe, effective and sustainable option for treatment of conductive and mixed hearing loss or single-sided deafness.
Zusammenfassung Hintergrund Die Corona-Krise beeinflusst nicht nur das professionelle Handeln, sondern auch die Lehre an den Universitäten. Schlagworte wie „E-Learning“ und „Digitalisierung“ suggerieren die Möglichkeit innovativer, ad hoc verfügbarer Lösungsansätze für die Lehre in der aktuellen COVID-19-Situation. Die aktuelle Umstellung auf digitale Lehre ist aber nicht primär durch eine didaktische Sinnhaftigkeit oder institutionelle Strategie, sondern durch äußere Notwendigkeit geprägt. Ziel der Arbeit Ziel der Arbeit war die Erfassung der Lehrsituation an nationalen Universitäts-HNO-Kliniken und akademischen Lehrkrankenhäusern zu Beginn des virtuellen Corona-Sommersemesters 2020. Material und Methode Ein eigens erstellter Fragebogen zur jeweiligen lokalen Situation, den örtlichen Rahmenbedingungen sowie zu bundesweiten Szenarien wurde an alle 39 nationalen Universitäts-HNO-Kliniken und 20 akademischen Lehrkrankenhäuser mit HNO-Hauptabteilung versandt. Ergebnisse Die ausgefüllten Fragebögen von 31 Universitätskliniken (UK) und 10 akademische Lehrkrankenhäuser (ALK) gingen in die Auswertung ein. Es zeigten sich offensichtliche Diskrepanzen zwischen verfügbaren Ressourcen und tatsächlich verfügbaren digitalisierten Lehrinhalten. Weitere Kritikpunkte offenbarten sich in Bezug auf die Kommunikation mit der Medizinischen Fakultät, die digitale Infrastruktur und insbesondere in der oftmals mangelnden Kollaboration mit den zentralen Supportstrukturen, wie Medien‑, Didaktik- und Rechenzentren. Schlussfolgerung Es gibt durchaus positive Beispiele für eine gelungene Überführung der Präsenzlehre in das ausschließlich virtuelle Sommersemester 2020 innerhalb der Universitäts-HNO-Kliniken. Mehrheitlich aber überwiegen kritische Einschätzungen der Lehrbeauftragten bzw. Ärztlichen Direktoren gegenüber der aktuellen Lehrsituation. Eine zeitkritische strategische Weiterentwicklung ist dringend erforderlich.
