S. Marti, N. Iob, D. Bächinger, C. Schlegel, A. Huber, J. Dlugaiczyk, A. Dalbert
TL;DR
A 54-year-old woman with cochlear implants experienced repeated pneumolabyrinth after barotrauma, leading to implant dysfunction and vestibular issues.
Contribution
This is the first reported case of recurrent pneumolabyrinth after cochlear implantation caused by barotrauma.
Findings
Pneumolabyrinth occurred three times within six years after barotrauma in a cochlear implant patient.
Each event caused acute peripheral vestibular hypofunction and cochlear implant dysfunction.
A perilymphatic fistula was surgically repaired each time, and preventive tubal dilation was performed.
Abstract
Bei einer 54-jährigen Patientin mit beidseitigen Cochleaimplantaten kam es links wiederholt zu einem Pneumolabyrinth nach Barotrauma. Dies resultierte jeweils in einer akuten peripher-vestibulären Unterfunktion und Cochleaimplantatdysfunktion. Eine als Ursache vermutete Perilymphfistel wurde bei 3 Ereignissen innerhalb von 6 Jahren jeweils operativ abgedeckt. Vorbeugend wurde schließlich eine Tubendilatation durchgeführt. Es handelt sich um die Erstbeschreibung eines durch Barotrauma induzierten, rezidivierenden Pneumolabyrinths nach Cochleaimplantation.
