To determine the surgical efficacy of a simplified retrosigmoid approach for vestibular nerve sectioning. ⋯ With excellent efficacy, short operative time, and a low incidence of postoperative hearing loss or headache, this simplified retrosigmoid technique should be considered for vestibular nerve sectioning in patients with intractable peripheral vestibular disorders.

We compared the treatment outcome of patients with benign paroxysmal positional vertigo unassociated with additional objective evidence of vestibular pathology (BPPV) with that in patients who did demonstrate additional vestibular pathology on standard neurotologic testing (BPPV+). ⋯ Our study demonstrates that patients with BPPV+ do not have a worse prognosis with respect to resolution of positional nystagmus, on performing the particle repositioning procedure, compared with patients with uncomplicated BPPV. However, they do suffer incomplete resolution of symptoms because of a coincidental anterior or horizontal canal dysfunction and otolithic or central vestibular dysfunction. It appears that the majority of patients with BPPV+ need further vestibular rehabilitation after the particle repositioning maneuver.
