Abstract
Ataxia is rarely attributed to lesions of the peripheral vestibular system. In 1973, the first case of ataxia and hearing loss secondary to a labyrinthine fistula was reported. Until now, this syndrome has not been reported in patients under the age of 10 years. A case is presented of a 5-year-old boy with symptoms of ataxia and hearing loss as well as vertigo and tinnitus after head trauma.
Three physical findings appear to be most characterisitic of patients with perilymphatic fistulas: a positive fistula response, positive positional testing with the involved ear down, and evidence of vestibular ataxia when testing station and gait.
The absolute diagnosis of perilymphatic fistula can only be established by exploration of the middle ear space. If a fistula is found, it may be sealed with soft tissue and, if this fails, actual stapedectomy may be required.
