[Labyrinthine fistulas: surgical management].

The authors presented management rules and the results of surgical treatment in perilymphatic fistulas. Materials comprise 7 cases of cholesteatoma and 6 cases after previously performed so called conservative modified operation of the ear. In 3 cases cholesteatomas were destroying the membranous structures or were being adherent to them. In these cases labyrinthectomy was performed with partial conservation of hearing in one patient. In the remained 10 cases the fistulas were cleaned and sealed with 3 layers of tissues--fascia, cartilage and fascia. After the ossicular chain was reconstructed in one stage. Discharge, and vertigo were stabilised in all cases. It was stated that cleaning of the labyrinthine fistula during cholesteatoma removal does not influence on bone conduction thresholds.
