[Congenital ossicular malformation: a study of 27 ears].
Despite otological surgical progress improving clinical congenital ossicular malformation management, some cases remain inadequately treated. We report 27 cases of congenital ossicular malformation, focusing on reasons for remaining or delayed postoperative hearing loss evaluated in 27 congenital ossicular malformation cases in Kyoto Prefecture from 2002 to 2008. Overall success was 93% (25/27) 6 months postoperatively. Two ears had no hearing improvement and three delayed hearing loss 8 to 48 months postoperatively. The first two ears underwent small fenestration stapedotomy with malleus attachment piston, and the other three tympanoplasty type III using an autologous ossicle or total ossicular replacement prosthesis (TORP) as a columella. We discuss problems and solutions using a malleus attachment piston or prosthesis, preoperative audio-and radiological findings, and operative findings including facial nerve anomaly and congenital cholesteatoma.
