The Round Window Diameter in Congenital Aural Atresia and Comparison With Sensorineural Hearing Loss and Control Group

Abstract

We found that both the RW diameter and RW membrane width in CAA were smaller than those in the control group. If this finding is supported in future studies, the production of floating mass transducer with different sizes may be useful. We suggest that RW diameter should be measured in each patient before operation and thus a floating mass transducer with the appropriate caliber should be chosen.
