IN AN INVESTIGATION of the results obtained by the labyrinth fenestration operation for otosclerosis, an analysis may be made on the basis of the various factors commonly known to be important in determining the suitability of the patient for operation. When such factors are considered separately and the operative results studied, facts may be discovered that have a significant bearing. For instance, a comparison of the results obtained in a group of patients from 15 to 25 years of age with a group from 45 to 60 years of age may reveal certain features that have significance in the selection of patients for operation and in the prognosis.
The chief factors concerned in the selection of patients with deafness for the fenestration operation may be enumerated as follows:
Degree of deafness of the patient
Type of deafness present, as determined by the following means
air conduction audiometry
