Predictors of residual-recurrent cholesteatoma in children.

The aggressive nature of childhood cholesteatoma has generated much controversy regarding the optimal management of this challenging disorder. To identify potential predictors of residual-recurrent disease, we studied 232 children (244 ears) treated with 427 surgical procedures between 1973 and 1990. Cause of the primary cholesteatoma was congenital in 43 patients (18%), acquired in 83 (36%), and unknown in 106 (46%). Of 90 patients with residual-recurrent disease, 21 (23%) instances were detected during a second-look surgical exploration. The 3- and 5-year residual-recurrence rates were 48% and 57%, respectively. Development of residual-recurrent disease was associated with ossicular erosion (Cox regression) but not with status of the canal wall (up vs down) during tympanomastoidectomy. This study suggests a need for intense and prolonged postoperative follow-up of children with cholesteatoma, especially those with ossicular erosion.
