[The reasons and treatments of recurrent or residual cholesteatoma in middle ears].
OBJECTIVE
To explore the reasons and treatments of recurrent or residual cholesteatoma in middle ears after operations.


METHODS
The clinical data of 102 cases (105 ears) with recurrent or residual cholesteatoma was retrospectively analyzed.


RESULTS
The main reason of recurrent or residual cholesteatoma is incomplete removal of cholesteatoma in the former operations or obstructive drainage of middle ears after operations. Twenty ears healed through cleaning with otoendoscope. Eighty-five ears underwent the second operations of radical mastoidectomy including 23 tympanoplasty meanwhile. The air-conductive auditory threshold of them all decreased more than 15 dBHL.


CONCLUSIONS
For the ears with low facial ridges and non-obstructive drainage of mastoid, tympanic antrum and tympanic cavity, its possible to be cured through cleaning with otoendoscope. For those with high facial ridges and obstructive drainage , it's essential to perform the second operations of radical mastoidectomy and some of them are suitable for tympanoplasty meanwhile.
