Abstract:
We report the case of a 54-year-old female patient with bilateral cochlear implants suffering from recurrent left-sided pneumolabyrinth due to barotrauma. These episodes caused acute peripheral vestibular disorder and cochlear implant malfunction. Over a 6-year period, the suspected causative perilymphatic fistula was surgically sealed on three occasions. A preventative balloon dilation of the Eustachian tube was finally performed. This case report is the first to describe barotrauma-induced recurrent pneumolabyrinth in a patient with cochlear implants.
