OBJECTIVE: To present the hearing results of a 5-year longitudinal study in a pediatric population undergoing surgery for extensive cholesteatoma using a canal wall up (CWU) approach with bony obliteration of the mastoid and epitympanic space, with a standard residual rate of 5.8%, a recurrence rate of 2.9%, and all ears waterproof, free of otorrhea and all external ear canals patent and self-cleaning. STUDY DESIGN: Retrospective consecutive study. PATIENTS: Thirty-three children (≤18 yr) undergoing surgery for cholesteatoma (34 ears) between 1997 and 2009. INTERVENTIONS: Therapeutic. SETTING: Tertiary referral center. MAIN OUTCOME MEASURES: Hearing and gain in hearing at 1- and 5-year postsurgery: (1) pure-tone average (PTA), (2) pure-tone average high frequency, (3) pure-tone average including 3 kHz, (4) bone conduction at corresponding frequency averages, (5) gain at corresponding air conduction and bone conduction (gain at corresponding air conduction) frequency averages. (6) The Amsterdam Hearing Evaluation Plots were used to study the individual cases. RESULTS: The Amsterdam Hearing Evaluation Plots at 5-year showed in 58.8% of patients a positive gain air conduction. In 23.5% a successful functional result was achieved, defined as an air-bone gap closure to 20 dBHL or less. In 6 patients (17.6%) a limited bone conduction deterioration was shown all limited to maximum 20 dBHL. CONCLUSION: The CWU bony obliteration tympanoplasty in a consecutive series of pediatric extensive cholesteatoma shows a similar to slightly improved hearing outcome as compared with CWU surgery without BOT. Although the series shows a clearly reduced reoperation rate and a significantly improved safety and hygienic outcome as compared with CWU without BOT, better hearing outcomes remain desirable in this group of children.
