CALIBRATED WEBER TEST IN FENESTRATION SURGERY: Evaluation of Postoperative Serous Labyrinthitis

POSTOPERATIVE serous labyrinthitis is one of the great problems in fenestration surgery today. To reduce or eliminate postoperative serous labyrinthitis, there must be a calibrated method of measuring its type, degree, and duration. To obtain this goal, we have calibrated the Weber test. By adapting the long-proved Weber test to the bone-conduction oscillator of the audiometer, it has been possible to demonstrate the variations in threshold and, with increasing intensity, variations in lateralization of sound. As presented, the calibrated Weber test may be described as a new hearing test; in actuality, it is only an audiometric adaptation of one of the oldest hearing tests. This test has been of value to us in determining the status and prognosis in our recent cases of fenestration. In summary, this article is the report of a study on the behavior of bone conduction in the recently fenestrated ear. As stated, the calibrated Weber
