INTRODUCTION: Our aim was to evaluate the results of surgery on @entity6515 over a ten-year period and to determine the postoperative recurrence rate and the factors responsible. MATERIALS AND METHODS: Forty-three @entity1 with 51 @entity6515 , who had been operated on in the period, 1 August 1990 to 1 August 2000, at the Department of Otolaryngology, Aarhus University Hospital, were asked to participate in a follow-up examination. Thirty-three @entity1 turned up for examination, four @entity1 were interviewed over the telephone, and for the rest the data available from the medical records were used. RESULTS: Surgical extirpation was performed on 51 @entity292 . Eight @entity292 had previously been operated on. The recurrence rate of the @entity292 primarily operated on at our department was 5%. The recurrence rate of secondary surgery was 63%. Five @entity292 were infected at the time of surgery, three recurred. Seven @entity1 developed a @entity86 , six of whom had a recurrence. All the @entity292 were blind-ended. In 94% of the histology tests, the @entity292 was lined with multilayered squamous epithelium. Sixteen @entity1 had a family history of the condition. CONCLUSION: @entity6515 is a benign disease that often stays asymptomatic, but can become troublesome if infected. The treatment is surgical extirpation. The recurrence rate rises if the @entity292 are infected at the time at surgery or if there has been an earlier attempt of extirpation. This emphasises the importance of an extended knowledge of the disease, so that @entity1 can be referred to an ENT specialist should symptoms occur.
