Efficacy of laser occlusion of posterior semicircular canal for benign paroxysmal positional vertigo: case report.

ABSTRACT

OBJECTIVE: To observe the long-term effect of laser occlusion of the posterior semicircular canal for benign paroxysmal positional vertigo. METHOD: Case report and review of the relevant world literature. RESULTS: We treated a patient with refractory benign paroxysmal positional vertigo using laser occlusion of the posterior semicircular canal, and achieved satisfactory results. Three months after the operation, the patient was able to lead a normal life. There was no recurrence over five years of follow up. CONCLUSION: To our knowledge, this is the first report in the world literature of a patient with refractory benign paroxysmal positional vertigo being treated with laser occlusion of the posterior semicircular canal. This method had long-term effectiveness, and may be one of the most effective methods of treating patients with refractory benign paroxysmal positional vertigo.
