Vestibular findings were studied in 27 patients with acoustic neurinoma. Four of them had experienced vertigo and/or dizziness at the onset of the disease, and 14 other patients had these complaints during the course. Vestibular symptoms were more prominent with middle-sized tumors which extended to the posterior cranial fossa than with those in the internal auditory canal. Although most acoustic neurinomas originate from the vestibular nerve, the incidence of vestibular symptoms is rather infrequent. This is probably due to a compensating mechanism of the central nervous system while the tumor grows slowly. Therefore, the growth rate of the tumor is considered to be most important for the concomitance of vestibular symptoms. The origin of the tumor was identified in 13 cases; in 3 it was from the inferior vestibular nerve and in 10 from the superior vestibular nerve. No significant difference in caloric test results could be seen between the tumors of different origins. The incidence of vestibular symptoms was more frequent when the tumor originated from the superior vestibular nerve than from the inferior vestibular nerve. The recover time required from the dysequilibrium after extirpation of the tumor depended on the degree of preoperative vestibular function.

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.

The authors investigated the clinical course of 49 patients with peritonsillar abscesses treated at Uwajima City Hospital between January 1983 and December 1995. The cohort consisted of 36 males and 13 females, aged 15 to 68 (mean age, 37.2 years old). Along with administration of antibiotics, removal of the abscess was performed by needle aspiration in 25 cases, and incision for drainage in 24 cases, respectively. There were no statistical differences in clinical stage and course between the group under 40 years old and the group over 40 years old. There was also no difference between the group treated with needle aspiration and the group treated with incision, except for the length of hospital stay healing time. Interval tonsillectomy was carried out in 10 cases. Recurrence of the peritonsillar abscess occurred in only one case. Therefore, we recommend needle aspiration as the first choice for treatment of peritonsillar abscesses. In cases of peritonsillar abscess with no past history of habitual angina, tonsillectomy is not indicated because recurrence of peritonsillar abscesses is rare.
