Abstract

The aim of this study was to evaluate the effectiveness and acceptance especially in the long-term with the active middle ear implant system Vibrant Soundbridge (VSB, MED-EL, Austria) in patients with aural atresia. With 51 subjects and a maximum follow-up period of 155 months (x̅=52.9 ± 33.2 months) this study presents the currently largest collection of patients with aural atresia and audiometric long-term results. The personal data and the audiometric results of the regular follow-up visits were evaluated in 51 patients who received a VSB implant between 2009 and 2019 in the Department of Otolaryngology at Ludwig-Maximilans-Universitätsklinikum Großhadern. The mean age of the study population at implantation was 13.9 years (SD=11.3), 42 patients (79.2 %) were children and adolescents and 11 patients (20.8 %) had reached adulthood. The follow-up period ranged from 1 to 155 months with a mean of 52.9 months or 4.0 years. The benefit of the VSB was evaluated by hearing tests (AC threshold, wobble tones), speech-tests (Freiburger Einsilbertest and Oldenburger Satztest) and by questionnaire (Speech, Spatial and Qualities of Hearing Scale). The results showed a significant improvement in hearing and speech comprehension after implantation in all test methods used. The values also remained largely constant over the long term, indicating a sustained functional gain of the VSB. The results of the questionnaire affirm the positive influence on the hearing and speech comprehension with the VSB. These results affirm the claim for using the active middle ear implant VSB as early as possible for patients with aural atresia.
