[Long-term results following cholesteatoma surgery].

A long-term review of 140 ears in 133 patients was carried out. All ears had first been operated on in 1971 and 1972 for cholesteatoma in the E.N.T. clinic. A closed technique was used in 110 ears and in the remaining 30 ears an open technique, depending on the pneumatisation of the mastoid, the extent of the cholesteatoma, tubal function and the age and social circumstances of the patient. At that time, second-look operations were carried out on relatively few patients after a closed operation. While the short-term results were favourable, recurrent cholesteatomas still developed 8 to 10 years later; 9 were discovered at this review alone. The long-term incidence of recurrence was 25%. Recurrent cholesteatomas were found in 57% of patients who were first operated on for a cholesteatoma before the age of 21, 24% of those between 21 and 40, and 11% of those between 41 and 60. These results reaffirm the necessity for a planned second-look operation in all young patients and also the importance of outpatient follow-up over many years.
