The curative effect of intact canal wall mastoidectomy and tympanoplasty in the treatment of cholesteatoma

Objective To explore the curative effect in patients with choleateatoma of the middle ear and the mastoid after intact canal wall mastoidectomy and tympanoplasty. Methods Seventy-eight patients with cholesteatoma underwent intact canal wall mastoidectomy and tympanoplasty from 2000 to 2005. The follow-up period ranged from 1 to 5 years. Results The closure rate of the tympanic membrane perforation was 89.74%. Recurrent perforation occurred in 3 cases postoperatively. Cholesteatoma recurred in 5 case. The postoperative hearing threshold level improved by 10 ～ 19 dB(average air conduction threshold) in 15 ears(19.23%), by 20 ～ 29 dB in 32 ears (41.03%), by more than 30 dB in 14 ears(17.95%) and 17 ears(21.79%) had no hearing gain. The cholesteatoma recurrent rate was 6.41%. Conclusion Intact canal wall technique is successful in treating chronic otitis media with cholesteatoma.
