CSF fistulas into the middle ear due to labyrinthine or tegmental anomalies are well known. They predispose to recurrent meningitis if they do not receive appropriate surgical treatment. CSF fistulas due to facial canal anomalies are extremely rare and predispose to the same risk of meningitis. The case reported enables a comparison to be made with the three other cases of the same form of anomaly found in the literature, and the diagnostic and therapeutic difficulties are also discussed.
