抄録

Forty-three patients (19 males, 24 females) with acoustic neurinoma who were treated in our clinic between 1984 and 1994, were analyzed clinically. Their ages ranged from 20 to 89 years (mean, 48.7 years). Comparisons were made of clinical data before and after April, 1989, when MRI was introduced into our hospital. Intracanalicular tumors or small tumors were diagnosed only after MRI was introduced. A case of normal ABR was also seen after the introduction of MRI. The incidence of head-shaking nystagmus and the average pure tone threshold were lower after April 1989. Furthermore, intracanalicular tumors showed low positive findings in function tests. In conclusion, MRI study is essential for the early diagnosis of acoustic tumors, but function tests are also informative in determining the extent of functional involvement.
