Pneumolabyrinth following eustachian tube insufflation.

P neumolabyrinth is a condition in which the vestibule and/or cochlea is filled with air. Eustachian tube insufflation (ETI) is a type of treatment for recurrent serous otitis media that is still popular in Europe. It exploits the anti-inflammatory and mucolytic effects of thermal waters containing sulfur and bromo-iodine gas. To our knowledge, no case of a pneumolabyrinth due to barotrauma provoked by ETI has been described previously. The aim of this article is to present a patient who developed a pneumolabyrinth following ETI.
