  • Abstract
  • Look Inside

Clinical and statistical observation was per-formed in 66 surgical cases (77 ears) of con-genital aural fistula.

The reults were as follows :

1. The opening of the fistulas was mostly detected in the marginal helicine type (48%) and the crural type (35%).

2. There were the cartilage-adhesion type (48%) in the marginal helicine type, and the cartilage-perforated type (63%) in the crural type.

3. Two cases of recurrence after operation were found in the branched cartilage-perforated type.

4. Recurrence can be avoided by excision of the cartilage around the fistula in the cases of the cartilage-perforated type.
