The chronic otitis media with cholesteatoma (COMC) may evoluate to intracranial and extra cranial complications, including the labyrithine fístulae. In this study, we present the evolution of our patients with labyrinthine fístulae. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: Ten out 82 patients with COMC had labyrinthine fístulae and underwent surgery from January/2001 to April/2002. They were assessed by clinical exam, computed tomography scans, and pre and postoperative audiogram. RESULTS: Hearing loss, otorrhea, tinnitus and dizziness were present in 100%, 90%,80%, and 40% of the cases. In one patient the fístulae was seen only in the coronal CT-scan, in another patient the fístulae was not seen neither in coronal nor axial images. Among the patients who had tinnitus, 66% referred improvement of this complaint after surgery. DISCUSSION: in the cases without invasion of the perilymphatic space, we noticed a tendency of improvement of the postoperative audiogram pattern and clinical outcome. In the extensive fístulae, on the other hand, there were no clinical changes. CONCLUSION: The CT-scan remains the best exam to assess the COMC with 90% of sensitivity for labyrinthine fístulae. In the stage II we had a good postoperative outcome.
