Abstract

Objectives/Hypothesis:

To investigate endolymphatic space images in patients with idiopathic sudden sensorineural hearing loss (ISNHL) and vertigo using three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI).

Study Design:

This is a prospective study of an analysis using the imaging technology of 3D-FLAIR MRI for patients with ISNHL and vertigo.

Methods:

3D-FLAIR MRI was performed 24 hours after intratympanic injection of gadolinium–diethylenetriamine penta-acetic acid.

Results:

In four of seven cases of ISNHL with vertigo, endolymphatic hydrops were confirmed in the cochlea and/or the vestibule of the affected ears.

Conclusions:

The results of the study imply that there may be some relationship between endolymphatic hydrops and ISNHL with vertigo. Laryngoscope, 2012
