Cholesteatoma otitis media with intact ossicular chain.
Thirty-one cases of cholesteatoma with intact ossicular chain were reviewed to examine the extension of cholesteatoma, operation procedures, pre- and postoperative hearing levels, and postoperative condition of the ear drum. They were operated on at Departments of Hyogo College of Medicine and Osaka University Medical School from 1989-1996, which were 20.4% of all of the primary cholesteatoma cases (n = 152). Twelve cases located at attic were operated by atticotomy or canal wall up and scutumplasty, 17 cases located at attic/antrum were operated by canal wall down and reconstruction, and two cases located around stapes were operated through the ear canal. Preoperative hearing level was mild (34.2 +/- 18.4 dB) and postoperative one was slightly improved (28.7 +/- 11.2 dB). In ossicular reconstruction, modified Wullstein type III method showed better hearing gain than Wullstein type I method. Postoperative attic retraction and/or pocket occurred in 15 cases (48.4%), but no recurrent cholesteatoma was found during the present follow-up period. These findings suggested that cholesteatoma with intact ossicular chain showed good postoperative hearing results, but postoperative retraction of the ear drum should be followed up for a long time.
