Summary
Sudden vestibular loss after head trauma can cause vertigo, mimicking vestibular neuronitis. Recovery varies, with some patients regaining partial function while others experience persistent vestibular areflexia.
Area of Science:
- Neurology
- Otolaryngology
Background:
- Vestibular neuronitis, a common cause of vertigo, is typically idiopathic or linked to viral infections.
- The etiology of vestibular neuronitis remains largely unknown, with viral origins frequently suspected.
Observation:
- This study presents 5 cases of unilateral vestibular loss following head trauma.
- Patients experienced vertigo but no hearing loss, with symptoms resolving over weeks.
Findings:
- Clinical presentation and course were comparable to idiopathic vestibular neuronitis.
- Partial vestibular function recovery occurred in 2 patients; 3 showed persistent vestibular areflexia.
Implications:
- Head trauma is a potential, previously unrecognized cause of vestibular neuronitis.
- Understanding trauma-induced vestibular dysfunction can refine differential diagnoses for vertigo.
