Rosen Mobilization and Stapedectomy: Long-Term Results With Special Reference to High Frequencies

FOR THE PAST few years I have been most interested in high frequency hearing research and have thus chosen to discuss a sample in which I was able to analyze 12,000 cycles per second (CPS) in addition to the lower frequencies. The sample chosen was selected with two requirements in mind: (1) a preoperative high frequency response at 12,000 CPS and (2) a postoperative high frequency test. These two requirements place one additional limitation on the sample—that of time, as we have only been doing high frequency testing in my office since late in 1962. All operations meeting the above criteria are included in this report. Only two types of operations were performed in this series in the following order: (1) Rosen mobilization (Figure), and (2) stapedectomy. The latter was employed only after mobilization failed. The following description of the Rosen mobilization operation appeared in the October 1966, issue of
