[Rupture of the round window. Differential diagnosis in sudden deafness and acute vestibular symptoms].

Rupture of the round window has to be considered in the differential diagnosis of sudden hearing loss with or without vertigo. The symptoms of this pathology vary a lot. No clinical examination with a sufficiently high selectivity and sensibility exists. The low therapeutical risk is stressed: exploratory and therapeutic tympanoscopy with grafting of the round and/or oval window.
