[Minor abnormalities of the internal ear. Radioclinical correlations].

Moderately severe cochleovestibular disorders of often late onset may arise from minor dysplasias of the internal ear. Diagnosis of these bone dysplasias is radiologic. The problem that arises is that of the indications for radiotomography of the internal ear, insofar as on the one hand no certain radioclinical equivalence exists, and on the other hand this radiologic examination is of greater diagnostic than therapeutic value.
