Comparison of small fenestra and total stapedectomy.

A biostatistical study of the results of 280 consecutive operations for clinical otospongiosis are analyzed over a seven-year period. One hundred forty-one (141) operations were done utilizing the "total stapedectomy" technique, and 139 were done utilizing the "small fenestra" technique. The auditory acuity of the two groups is compared with reference to conductive and sensorineural performance. All the surgery was performed by the authors, the data was collected by a third party and analyzed by a statistician. All audiograms were performed by the same audiologist under the same conditions. The data indicates that the preferred operation for this clinical disease is the small fenestra technique.
