[Evaluation of tympanoplasty with reconstruction of the external canal after mastoidectomy for cholesteatoma].
OBJECTIVE
To investigate the method to repair the deletion of external canal and opened mastoid space after mastoidectomy.


METHODS
One stage tympanoplasty with reconstruction of the external canal with temporal cortex was completed in 58 cases (58 ears) with cholesteatoma.


RESULTS
During the follow-up ranging from one to three years, there was only one relapse. The configuration of external canal was almost normal and pneumatic mastoid space was maintained. Hearing was improved over 30dB in five ears, 20 to 29 dB in 11 ears, 10 to 19 dB in 30 ears, less 10 dB in eight ears and hearing wasn't improved in four ears.


CONCLUSIONS
One stage tympanoplasty with reconstruction of the external canal after mastoidectomy for cholesteatoma is a practical way to improve hearing and decrease recurrence.
