At the meeting of the Southern Section of The Triological Society in Naples, Fla, George Lesinski, MD, and Cynthia S. Whitehurst, MS, Cincinnati, Ohio, presented a study of 25 patients with traumatic intermittent perilymph fistula. Of 44 patients (48 ears) who underwent exploratory tympanotomy during the period 1983 through 1988, 25 experienced the onset of auditory and vestibular symptoms immediately following blunt trauma or barotrauma. Abnormalities were found in 27 of 28 oval windows, and surgical repair was performed in all 28 oval windows. The predictive value of positive or negative pressure coupled with findings from an electronystagmogram in predicting the presence of a fistula was low, in that several false-negative findings were discovered. Dr Lesinski presented an interesting videotape that documented anterior lateral rotation of the footplate, which separated from the annular ligament anteriorly and inferiorly. The fistula was repaired by first lysing the mucosal adhesions surrounding the stapes
