Atticotomy with canaloplasty and tympanoplasty for limited epitympanic cholesteatoma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To observe the surgical results of atticotomy with canalopalsty and tympanoplasty for limited cholesteatoma.@*METHOD@#Thirty-one cases of limited epitympanic cholesteatoma and retraction pocket received atticotomy. The surgical procedure consisted of eliminating cholesteatoma and pocket, reconstructing lateral epitympanic wall and tympanoplasty with cartilage/perichondrium island flap.@*RESULT@#The anatomic pattern of external ear canal appeared near normal, and the hearing level improved or remained normal during 2-year follow up except for 2 cases with tympanosclerosis. No epitympanic retraction pocket or cholesteatoma relapsed. 1 case appeared tympanic perforation.@*CONCLUSION@#Atticotomy, contemporaneous reconstruction of lateral epitympanic wall and tympanoplasty with cartilage/perichondrium, indicated to be a reliable treatment and prevention technique for epitympanic cholesteatoma. It can achieve good morphological and functional results.
