A case of barotrauma-induced pneumolabyrinth secondary to perilymphatic fistula.

We report the case of a 62-year-old woman who experienced pneumolabyrinth associated with a perilymphatic fistula. Her condition was diagnosed with the help of computed tomography, which detected the presence of an air bubble in the labyrinth, and middle ear exploration, which revealed that clear fluid was emanating from the round window niche in a manner consistent with the presence of a perilymphatic fistula. The niche was repaired with tragal perichondrium and bolstered with Gelfoam.
