It has been reported by many investigators that there is a correlation between the degree of the ossicular malformation and the auricular deformity in cases with the atresia or the narrow external meatus. This correlation, however, has not established in the middle ear malformation with the normal external meatus. The purpose of this paper is to study this correlation. The subjects are 60 ears (49 patients) of the middle ear malformation with the normal external meatus. Their occicular findings are confirmed operatively. Ossicular anomalies were classified into two groups according to the retrospectively estimated numbers of the maldeveloped foci. One is monofocal type with only one maldeveloped process, and the other is multifocal type with more than two maldeveloped processes. <br>As the result, the monofocal type was more frequently observed than the multifocal type in cases with the normal auricule, the jaw and the face or in unilaterally affected cases. In contrast, the multifocal type was more frequently observed in cases with some anomalies of the auricle, the jaw and the face or in bilaterally affected cases. This difference has been proved to be significant by the Chi-square test. <br>It is concluded that checking of the items above mentioned is important in middle ear malformations with the normal external meatus, because the multifocal type is more frequently observed in cases with some anomalies of the auricle, the jaw and the face or in bilaterally affected cases, and because surgical correction is also more difficult in these multifocal type anomalies.
