Eine Cochlea-Implantat-Versorgung reduziert langfristig die Tinnitusbelastung bei älteren Patienten

Zusammenfassung

Hintergrund Tinnitus gehört bei hochgradig schwerhörigen bzw. ertaubten Patienten zu den häufigsten otologischen Komorbiditäten. Das Cochlea-Implantat (CI) kommt vermehrt auch bei älteren Patienten zur Hörrehabilitation erfolgreich zum Einsatz. Ziel dieser Nachuntersuchung war die Beurteilung der Tinnitusbelastung im Langzeitverlauf bei älteren Patienten nach Hörrehabilitation mittels CI.

Material und Methode In diese prospektive longitudinale Untersuchung konnten 15 Patienten zwischen dem 72. und 92. Lebensjahr mit einem präoperativen unstillbaren Tinnitus eingeschlossen werden, die vor etwa 6 Jahren erstmalig unilateral mit einem CI versorgt wurden. Es erfolgte die Erhebung des Einsilbersprachverstehens sowie der Tinnitusbelastung mithilfe des Mini-Tinnitus-Fragebogens. Die Ergebnisse wurden mit unserer vorangegangenen Untersuchung [24], in der wir die ersten 6 Monate nach CI-Versorgung betrachteten, verglichen.

Ergebnisse Sechs Jahre postoperativ kam es zu einer nicht signifikanten Zunahme des Einsilbersprachverstehens auf 61,7±26,3%, verglichen mit den Ergebnissen 6 Monate postoperativ (p=0,069). Die Belastung durch den Tinnitus zeigte sich 6 Jahre postoperativ mit 3,9±3,6 Punkten im Mittel, verglichen mit der 6-Monats-Kontrolle, stabil niedrig (p=0,689) und deutlich reduziert zum präoperativen Status mit 6,9±6,5 Punkten (p=0,016).

Schlussfolgerung Die Hörrehabilitation mit CI führt bei älteren Menschen zu einer anhaltenden Verbesserung der Einsilberdiskrimination und zu einer langfristigen Reduktion der Tinnitusbelastung.

Abstract

Background Tinnitus is one of the most common otologic comorbidities, particularly in older patients with severe hearing loss or deafness. Cochlear implants (CI) have been used for hearing rehabilitation more and more successfully in elderly patients and CI treatment is performed in Germany without an age limit. The aim of this follow-up study was to assess the tinnitus burden in the long-term follow-up of elderly patients with hearing rehabilitation using CI.

Material and Methods This prospective longitudinal study included 15 patients between 72 and 92 years of age with preoperative tinnitus who had been treated unilaterally with a CI for the first time about six years ago. Monosyllabic speech understanding and tinnitus burden were assessed using the Mini-Tinnitus Questionnaire. The results were compared with our previous study [24], focusing on the first six months.

Results Six years postoperatively, there was a nonsignificant increase in monosyllabic understanding to 61.7 ± 26.3%, compared with the results six months postoperatively (p = 0.069). The burden of tinnitus showed a stable low mean of 3.9 ± 3.6 points six years postoperatively, compared with the six-month control (p = 0.689) and significantly reduced compared to the preoperative status with 6.9 ± 6.5 points (p = 0.016).

Conclusion Hearing rehabilitation by using CI leads to a stable improvement of monosyllabic discrimination in elderly people as well as to a stable reduction of tinnitus burden over years.
