Background and Objectives: The incidence of recurrence after surgery of congenital cholesteatoma is increasing due to the widespread use of otoendoscopy as well as an increased awareness of these lesions among primary care physicians. There is no general consensus on the risk factors affecting recurrence. In this study, analyzing clinical characteristics of recurred cases from a tertiary hospital, we investigated risk factors for the recurrence of congenital cholesteatoma after surgery.
Subjects and Method: From 1999 to 2016, data were collected from retrospective chart reviews of patients who have undergone surgeries for congenital cholesteatoma at Hospital. We analyzed data about clinical characteristics and recurrence according to the age at diagnosis, location, stage and type of disease, pneumatization of mastoid, ossicular erosion, and surgical techniques.
Results: Sixty-eight patients underwent surgery for congenital cholesteatoma. The average age at operation was 4.8 years. Recurrence was detected in 7 cases of the 68 patients, with the recurrence rate of 10.3%. Sex, age, cholesteatoma type, location, stage, mastoid pneumatization, and operation method did not show significant differences between the recurred group and the non-recurred group in the univariated analysis.
Conclusion: The recurrence rate of congenital cholesteatoma after primary operation was 10.3%. In this study, there was no statistically significant risk factor for postoperative recurrence of congenital cholesteatoma.
