title: [Our surgical treatment results in pediatric cholesteatoma].
abstract: OBJECTIVE
  This study aims to evaluate surgical techniques and obtained outcomes in pediatric cholesteatoma.
  
  
  METHODS
  A total of 62 patients (41 males, 21 females; mean age 13 years; range 3 to 17 years) diagnosed as pediatric cholesteatoma between January 1998 and December 2014 were enrolled into the study. Of the patients, canal wall down (CWD) mastoidectomy was performed in 31, canal wall up (CWU) mastoidectomy in 13, inside-out (ISO) mastoidectomy in eight, and tympanoplasty in 10. Surgical approaches, staging, hearing outcomes, relapse status, and surgical data were retrospectively analyzed.
  
  
  RESULTS
  Cholesteatoma recurred in seven patients (11%). Recurrence rates for CWU and CWD mastoidectomies were 31% and 6%, respectively. While the number of patients with good serviceable hearing (pure-tone average ≥25 dB) was 10 preoperatively, it became 16 postoperatively. Ossicular erosion was higher in CWD group. Twenty-nine patients (47%) had extensive disease and CWD mastoidectomy was performed in 86% of these. Number of patients not requiring care was 45 (72.6%).
  
  
  CONCLUSIONS
  In this study, we observed no differences in terms of good serviceable hearing between CWU and CWD mastoidectomies. The preferred method was mainly CWD in patients with extensive disease and ossicular erosion. Recurrence rates were higher in CWU group. Therefore, ISO or CWD mastoidectomy come to the forefront as appropriate treatment options in the treatment of pediatric cholesteatomas according to the extensiveness of disease.
