  • 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.

  • Relationship between the affected ear in benign paroxysmal positional vertigo and habitual head-lying side during bedrest

  • Objective: To assess the association between the habitual head position during bedrest and the affected ear in benign paroxysmal positional vertigo (BPPV).

    Study design: Prospective trial of patients with active BPPV of the posterior semicircular canal, confirmed on physical examination.

    Methods: Seventy-five patients were asked to explain the head position and lying side they were accustomed to before falling asleep in bed.

    Results: Fifty patients (67 per cent) habitually adopted a lateral head position during bedrest. The ear affected by BPPV was found to be consistent with the head-lying side during bedrest in 43 cases (86 per cent) (29 cases for the right ear and 14 cases for the left ear).

    Conclusion: Habitual lateral head-positioning during bedrest can be a major factor leading to the development of BPPV in the ipsilateral ear.
