Is there consensus in perilymph fistula management?
A perilymph fistula is an abnormal communication between the inner ear fluids and the middle ear space. This article identifies areas of agreement in perilymph fistula management based upon 167 questionnaire responses from active surgeons of the American Otological Society and the American Neurotological Society. The average respondent performed 4.6 fistula explorations among 197 otologic surgeries (some of these were myringotomies) per year. The following statements represent areas of general agreement. The single most important feature of the history is previous trauma or barotrauma. At present no test can replace clinical judgment; however, despite sound judgment and sophisticated testing, it is very difficult to document the presence or absence of a fistula preoperatively. Most often the diagnosis is based on the total clinical picture: history, physical examination, and laboratory testing.
