The operative findings of traumatic vertigo were studied in 65 patients who had surgery for middle ear trauma. A complaint of vertigo was present in 23 patients and absent in 42. A perilymphatic fistula was found in 19 patients with vertigo and 2 patients without vertigo. The incidence of perilymphatic fistula was correlated with the accompanying symptoms. There was no positive correlation with loss of consciousness, or temporal bone fracture or ossicular dislocation, but there was a positive correlation with the way the traumatic force acted on the inner ear windows. Vestibular function tests in the 19 fistula patients with vertigo showed positional nystagmus in 12 cases and a fistula sign in 10 cases. These two tests are considered to be important in the diagnosis of perilymphatic fistula.
