Validity of staged surgery for congenital cholesteatoma based on the verification of residual recurrence risk

Abstract

Staged surgery is often selected for congenital cholesteatoma because of frequent residual recurrence. However, because it often occurs in children, it is desirable to select staged surgery according to the residual recurrence risk.

We examined the residual recurrence risk and validity of selecting staged surgery in 27 ears of 27 patients who underwent congenital cholesteatoma surgery in our hospital between January 2008 and April 2018.

Residual recurrence occurred in 26% of the 27 ears. The rate of residual recurrence was significantly higher in patients with advanced cholesteatoma and ossicular defects. Staged surgeries were more frequently performed in patients with stage Ic cholesteatoma and ossicular defects, as well as in those with stage II or higher cholesteatoma. Among these patients, the residual rate was found to be high.

The extent of cholesteatoma progression and ossicular defects may be an indicator for staged surgery. We must select staged surgery for patients with stage Ic cholesteatoma and ossicular defects and for those with stage II or higher cholesteatoma.
