| Popis: | Five cases of von Recklinghausen's disease were found in one family. In three of them, bilateral acoustic neurinoma were observed. The pure tone audiometry was performed repeatedly in two of them and the changes of audiograms were studied.Clinical signs and symptoms of these cases seem quite different from those in unilateral acoustic neurinoma.The changes in audiograms revealed the two periods in the progress of hearing loss. They were rapidly increasing periods and slowly increasing periods.These results suggest the etiology of the bilateral acoustic neurinoma in von Recklinghausen's disease is different from other acoustic neurinoma. |
