Endoscopic transcanal approach to the middle ear for management of pediatric cholesteatoma

Outcomes for endoscopic ear surgery (EES) for pediatric cholesteatoma at a tertiary pediatric hospital.

Methods: Retrospective case series of 65 pediatric cholesteatoma cases in 38 ears. Subgrouping based on cholesteatoma type and EES type. Surgical findings, outcomes, and demographic data were evaluated.

Results: Endoscopes were used in 65 pediatric cholesteatoma cases in 38 primary ears (34 patients), followed for an average of 2.6 years (9 months to 4.6 years). The endoscope was used as the primary visualization tool in 31 (81.6%) ears (EES 2 or 3), and as an adjunct to the microscope in seven ears (EES 1). Twenty-two (57.9%) ears and 35 (53.4%) cases were transcanal endoscopic ear surgery (EES 3 or TEES). Overall, there was recurrence in five (13.2%) ears and residual in four (10.5%) ears. Cholesteatoma was acquired in 27 ears, with average age 10.9 years; and congenital in 11 ears, with average age 3.8 years. Surgical time was longer for acquired cases (226 vs. 154 minutes). Hearing outcomes were comparable for both cholesteatoma types. Residual disease was seen in three (11.1%) acquired ears and one (9.1%) congenital ear. Overall, the lowest rates of recurrent and residual disease were seen in EES 3 cases, and relatively low rates in EES 2 and 3 ears, including four (12.9%) recurrences and two (6.5%) ears with residual disease.

Conclusion: The endoscopes are a viable tool for resection of pediatric cholesteatoma and provide excellent visualization of the middle ear and associated recesses.
