Abstract
We classified cases of pars tensa cholesteatoma who underwent initial surgery at our institute based on the Classification and Staging of Cholesteatoma proposed by the Japan Ontological Society in 2010.
Between 2008 and 2012, 34 cases of pars tensa cholesteatoma were treated by surgery in Jikei University. The patients ranged in age from 11 to 68 (average 42.0) years and included 17 males and 17 females. The postoperative observation period was more than a year, with a mean follow-up period of 35 months. In regard to the stages, 14 ears (41.2%) were classified as stage I, 16 ears (47.1%) as stage II and 4 ears (11.8%) as stage III cholesteatoma. Ossiculoplasty was performed for 5.9% cases of Type I, 58.8% of Type II and 35.3% of Type III cases. Successful postoperative hearing outcomes were obtained in 50% of the cases. The recurrence rate of cholesteatoma was 5.9%, which was relatively good in comparison to previous reports. These results suggest that cartilage tympanoplasty and application of endoscopy for ear surgery is useful for minimizing the recurrence rate after surgery.
