ABSTRACT

A perilymphatic fistula is defined as an abnormal communication between the inner ear and middle ear. The auditory and vestibular systems can be affected in different degrees, the main symptoms are progressive sensorineural hearing loss and vertigo. The term «pneumolabyrinth» refers to the presence of air inside the labyrinth, it is an infrequent finding that confirms the diagnosis of a perilymphatic fistula. The most frequent cause is traumatic, other causes are: barotrauma, iatrogenic, erosive and idiopathic. In the context of cholesteatoma, labyrinthine fistula secondary to bone erosion is common. In this, unlike the perilymphatic fistula, the endosteum remains intact. Perilymphatic fistula is not frequently reported as a complication of chronic cholesteatomatous otitis media. The management of perilymphatic fistula is not standardized since it depends on the etiology and clinical evolution of each patient. In most cases, conservative management is recommended, reserving surgical treatment in cases of severe vestibular symptoms, progression of hearing loss or suspicion of active perilymphatic fistula. We present a clinical case of a 73-year-old patient with a history of chronic cholesteatomatous otitis media, who after cleaning and aspiration of otorrhea in the clinic presented symptoms compatible with perilymphatic fistula corroborated by pneumolabyrinth, with erosion of the oval window. pneumolabyrinth is a rare complication of chronic cholesteatomatous otitis media. In this case we consider surgical management was necessary to eradicate the disease and closure of the fistula, to prevent complications to the central nervous system.
