Comparison of congenital and acquired cholesteatomas in pediatric patients

Abstract

Objectives: This study aims to present clinical data and surgical results of patients with congenital cholesteatoma (CC) and acquiredcholesteatoma (AC).Patients and Methods: Pediatric cholesteatoma patients who underwent tympanomastoid surgery between January 2008and June 2015 were evaluated retrospectively. Demographic data, clinical symptoms, surgical and post-surgical findings wererecorded. Mastoid development was evaluated with preoperative temporal bone computed tomography. Areas with cholesteatomawere mapped intraoperatively and cholesteatoma was staged. Intraoperative stapes superstructure deformation was assessed.Postoperative hearing results were compared according to air bone gap (ABG) values. Statistical analysis was made by MannWhitney U and Kruskal Wallis test.Results: We analyzed 60 patients (9 CC and 51 AC) under 16 years of age and followed at least six months. In the CC and AC groups,mean age was 6.1 and 10.4 years, and mean follow-up was 28 and 32 months, respectively. While CC group patients were generallyasymptomatic, AC group patients were diagnosed with complaints of otorrhea, otalgia and hearing loss. Mastoid development wasbetter in CC group patients (p
