Sinus Cholesteatomas. Recurrencies and Observation Time

Abstract

271 ears operated for sinus cholesteatoma are evaluated according to residual and recurrent cholesteatoma. 90% are reevaluated with a median observation time of 9,75 years. All residual cholesteatomas are seen within the first four postoperative years. Recurrent cholesteatoma can be seen at any time. Because of only few and early seen residual cholesteatomas one-stage procedures are recommended. The paper gives some guidelines for the treatment of the sinus cholesteatoma, i.a. a cholesteatoma originating from a posterio-superior retraction (perforation) of the pars tensa.
