Canal wall-down mastoidectomy with mastoid obliteration for pediatric cholesteatoma.

Conclusions: As cholesteatoma is widespread and erosive, it should be cleared away thoroughly, to keep a dry ear and conserve maximum hearing ability in children. Canal wall-down mastoidectomy with mastoid and epitympanum obliteration is a good choice for treatment of cholesteatoma in children.

Objective: To investigate canal wall-down mastoidectomy with mastoid and epitympanum obliteration for the treatment of cholesteatoma in children.
