Cholesteatoma Recidivism in Pediatric Versus Adult Patients: Disease Extent and Prognostic Factors

The Laryngoscope, EarlyView.
In this retrospective cohort of 128 primary cholesteatoma surgeries, patients younger than 20 years had a higher 5‐year cumulative recidivism risk than adults (53.9% vs. 19.1%) and more frequent sinus tympani involvement at recidivism (38.5% vs. 5.6%). Pediatric age, supratubal recess involvement, mastoid extension, and mastoidectomy omission relative ...
