title: Management of the labyrinthine fistula in cholesteatoma surgery.
abstract: The presence of a labyrinthine fistula has remained one of the major problems in cholesteatoma surgery. Confronted with this problem, the surgeon may ultimately base his choice of procedure on four basic conditions: the size of the fistula, its location in the ear, the condition of the other ear, and the cochlear function. Our attitude has been changing, and currently we prefer to perform a staged closed tympanoplasty. When a closed technique is performed, we either remove the cholesteatoma matrix and then cover the fistula immediately or we leave the matrix in situ and re-explore the mastoid process 5 or 6 months later. The series consists of 88 cases out of a total of 701 patients with cholesteatoma operated on between January 1971 and June 1982. In 20 patients the matrix was left over the fistula at the first stage. The results suggest that a staged operation, i.e. closed tympanoplasty, is to be preferred even in cases with an extensive labyrinthine fistula.
