Transtympanic administration of aminoglycosides in patients with Menière's disease
1ENT Department, Hospital of Mestre, Venice, Italy.
Abstract:
Transtympanic administration of gentamicin was used to treat patients with unilateral Menière's disease and was stopped at the first signs of damage to cochlear and/or vestibular function. Twenty-eight patients were treated between 1974 and 1981 and 34 patients were managed between 1981 and 1987. In the two groups of patients, objective vertigo disappeared in 85%, hearing improved in 26%, aural fullness disappeared in 78%, while tinnitus ceased altogether in 51% and became less intense in 24%. Our findings show that this kind of treatment can be used after unsuccessful medical therapy and prior to any labyrinthine or endolymphatic sac surgery.
