Summary
Benign paroxysmal positional vertigo (BPPV) resolved after laser treatment targeting the utricle and singular nerve. This case highlights a potential treatment for intractable vertigo, even with uncertain nerve identification.
Area of Science:
- Otolaryngology
- Neurosurgery
- Vestibular System
Background:
- A patient presented with persistent benign paroxysmal positional vertigo (BPPV) three years after surgical closure of a perilymph fistula.
- The vertigo symptoms were long-lasting and refractory to conventional treatments.
Observation:
- The patient underwent laser treatment targeting the macula utriculi and utriculoampullary nerve via the oval window.
- A singular neurectomy was attempted using an Argon laser, though the singular nerve was not definitively identified.
Findings:
- Post-operatively, the patient's vertigo symptoms completely resolved.
- Pure tone average remained stable at 50 dB, suggesting no significant hearing loss.
- Ocular counter-rolling indicated reduced function of the irradiated utricle, and the singular nerve sectioning status remained uncertain.
Implications:
- This case suggests that laser treatment, potentially involving destruction of the macula utriculi and/or singular neurectomy, can effectively resolve intractable BPPV.
- The findings imply that successful treatment may occur even when surgical targets, like the singular nerve, are not clearly visualized.
- Further research is warranted to elucidate the precise mechanisms and optimize this therapeutic approach for vestibular disorders.
