Abstract
Three Patients, from 11 to 30 years old, with congenital meatal atresia accompanied by microtia were successfully treated by the authors. One of them had bilateral atresia. By plastic formation of new auricles and myringostapediopexy the authors obtained following results.
1. Hearing gains after operations were as follows:
a gain of 48 decibels to a 37 decibel level,
a gain of 63 decibels to a 27 decibel level,
a gain of 25 decibels to a 25 decibel level and
a gain of 33 decibels to a 38 decibel level in speech range.
2. The new auricles were constructed by means of rib cartilage implant that had been buried in the subcutaneous tissue at which the new auricles are to be constructed.
Although the new auricles thus constructed are by no means satisfactory ones for the authors, they seem to have better appearance than those which are constructed by means of tube graft.
