Abstract
[ABSTRACT]OBJECTIVETo investigate the treatment choice and curative effect of stage III external auditory canal cholesteatoma (EACC) with different degrees of damage to the posterior wall of external auditory canal and mastoid.METHODS44 patients (45 ears) diagnosed with III type external auditory canal cholesteatoma and treated with different surgeries were collected: 27 ears with damages of mastoid which did not involve tympanic antrum (group A) underwent simple mastoid repair+external auditory canal plasty+conchoplasty (in necessity). 18 ears with damages of mastoid which involve the tympanic antrum (group B) underwent mastoidectomy+mastoid filling+external auditory canal plasty+conchoplasty. RESULTSAll patients were followed up for 1 to 2 years postoperatively. There was no recurrence of cholesteatoma, no external auditory canal collapse, stricture or atresia,and hearing improved to different degrees. The postoperative dry ear rate of group A and group B was 100% and 94.4% respectively. The mean duration of dry ear in group A and B was (12.1±2.3) and (28.1±3.5) days respectively. The cases with smooth external auditory canal and good self-purification in group Aand B accounted for 100% and 88.9%respectively.CONCLUSIONType III external auditory canal cholesteatoma can be treated with different surgical methods according to different damages of mastoid. The cases in which damages of mastoid did not involve tympanic antrum can be treated with simple mastoid repair+external auditory canal plasty+conchoplasty (in necessity). The cases in which damages of mastoid involved tympanic antrum can be treated with mastoidectomy+mastoid filling+external auditory canal plasty+conchoplasty.关键词
