Comparison of Ear-Canal Reflectance and Umbo Velocity in Patients With Conductive Hearing Loss: A Preliminary Study

Abstract

The combination of |ECR| with audiometry showed clinical utility in the differential diagnosis of conductive hearing loss in the presence of an intact tympanic membrane and an aerated middle ear and seems to be of similar sensitivity and specificity to measurements of VU plus audiometry. Additional research is needed to expand upon these promising preliminary results.
