Abstract

Objective:The aim of this study is to explore the correlation between radiological classification on HRCT and effects on surgery with hearing improvement in otosclerosis. Method:Thirty three patients (66 ears) with otosclerosis were enrolled to this study, who would be done operation using Fischs stapes surgery technique. All patients were classified according to axial HRCT preoperatively. All patients were evaluated by pure tone test preoperatively and 6 months postoperatively. Correlation between radiological classification and hearing effects were studied. Result:Six months after the surgeries, both of air conduction thresholds and bone conduction thresholds in 33 patients were significantly improved than those before the surgeries (P<0.01). Compared with mixed type otosclerosis, window type otosclerosis had significantly lower bone conduction threshold preoperatively and postoperatively. Conclusion:Fischs stapes surgery technique have perfect effects on improving otosclerosis air conduction threshold, as well as bone conduction threshold.

Auditory Perception

Auditory perception is the ability to receive and interpret information attained by the ears. Here is the latest research on factors and underlying mechanisms that influence auditory perception.
