Prognostic factors of recidivism in pediatric cholesteatoma surgery.
OBJECTIVE
To analyze the results on a series of pediatric cholesteatomas, using various preoperative factors, including some of the proposed classification systems, to identify those factors that influence the postoperative result.


METHODS
Retrospective review of 118 children with acquired cholesteatoma who underwent surgery from January 1978 to October 1999. The median observation period was 5 years, range 1-20 years. The rate of recidivism calculated using the Kaplan-Meier method and relative risk by the Cox regression model.


RESULTS
Cholesteatoma in patients less than 8 years old with mastoid involvement had significantly higher risk of recidivism than the other groups examined.


CONCLUSIONS
In this study, cholesteatoma recurred up to 5 years after operation, and long-term close follow-up is important especially in cases involving higher risk such as younger child with mastoid extension of cholesteatoma.
