Abstract:   (3936 Views)
Various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. Both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution CT scan. It was found that in approximately one third of the patient group (with idiopathic SNHL), the vestibular aqueduct was 1.5 mm or larger. Also, the midpoint diameter of the distal limb was larger than in the control group (p<0.01). But there was no relation between the various dimensions of the vestibular aqueduct and mastoid pneumatization.
Keywords: Large vestibular aqueduct, Congenital SNHL, Temporal bone CT scan.
