    Abstract:
    To evaluate the rates of residual and recurrent cholesteatoma following canal wall reconstruction (CWR) tympano-mastoidectomy with mastoid obliteration, for the treatment of chronic otitis with cholesteatoma. Consecutive cohort study. We included patients following surgical cholesteatoma removal by CWR tympano-mastoidectomy with hydroxyapatite mastoid obliteration from 2008 to 2012. We analyzed audiometric and postoperative radiologic data. We determined the rates of residual disease and recurrence, and evaluated postoperative complications. Thirty-six ears were included in this study. The mean follow-up after surgery was 24 months (range 12.3-51.4 months). The recurrence rate was 3.1% (one case) and the rate of residual disease was 6.2% (two cases including one of iatrogenic cholesteatoma). No canal-wall-down tympanoplasty was required. Local infection was detected in 33% of cases and was successfully treated with appropriate antibiotics. Postoperative audiometry showed no impairment of the cochlear reserve. No postoperative facial palsy or deafness was observed. CWR permits well exposure of the lesion, making complete excision of the cholesteatoma possible. This study showed a decreasing of the rate of residual cholesteatoma and must be confirmed with further studies. CWR makes it possible to use hearing aids for auditory rehabilitation.
