title: [Labyrinthine fistulae].
abstract: The study is based on 44 cases of labyrinthic fistulas which were almost always discovered per-operatively. The authors describe the different stages of evolution, grouped under the term of "fistula". Having summed up the main therapeutic guidelines published since 1950 and following the study of the different cases presented, a therapeutic approach is proposed which takes into account the condition of the opposite ear and the open or closed technique selected. As far as audiometry is concerned, the cochlear reserve must be safeguarded. Technically speaking, the best attitude is to carry out the ablation of the matrix in one or two phases depending on the size, to prefer a closed technique and to drain the fistula at the end of the operation.
