Introduction

Labyrinthitis is self-limiting inner ear disorder, often secondary to viral infection. The infection of vestibular neuron and labyrinth primary affects balance and hearing. The condition is commonly called as vestibular neuritis/ vestibular neuronitis.

Pathophysiology

The major cause for labyrinthitis is known to be viral infection or post-viral inflammatory disorder that mainly affects the vestibular portion of eighth cranial nerve. The exact cause of labyrinthitis or vestibular neuronitis is still not clear. MRI with contrast had shown enhancement of the vestibular nerve fibers within the internal auditory canal, suggesting inflammatory process.
