Three-dimensional wideband absorbance immittance findings in young adults with large vestibular aqueduct syndrome

Abstract

Objective: To investigate the effect of large vestibular aqueduct syndrome (LVAS) on middle ear sound transmission using wideband absorbance immittance (WAI). Methods: WAI results from young adult LVAS patients and normal adults were compared. Results: Averaged energy absorbance (EA) at ambient and peak pressure in the LVAS group showed differences to the normal group. Under ambient pressure, the average EA of the LVAS group was significantly higher than the normal group at frequencies 472–866 Hz and 6169–8000 Hz (p
