What do you know about superior semi-circular canal fistula? What is the best way to cure this disease? A friend of mine suddenly experienced hearing loss after blowing his nose. Several days after, he experienced dizziness/vertigo. He consulted a doctor and this doctor requested for CT Scan- the result was normal. But another doctor (specialist) who examined his ct scan plates, found out that he has a fistula in his inner ear.  MRI was also requested but again, results were normal. Is it possible that both examinations done to him can't reveal that he has a fistula? Until now my friend cannot work because of his condition. What are the chances that my friend would be able to hear again normally? Are there medications or if not, surgical procedure which can be performed to restore his hearing? Please help my friend...
