To determine whether, in patients with benign paroxysmal positional vertigo (BPPV), the canalith repositioning procedure performed with vibration applied over the mastoid bone of the affected ear is more effective in resolving the symptoms and preventing recurrence of BPPV than the procedure performed without vibration. ⋯ Our results suggest that, while the canalith repositioning procedure is effective in the treatment of BPPV, vibration applied during the maneuver does not significantly affect short-term or long-term outcomes.

Lingual nerve injury is an uncommon complication of laryngoscopy. We report a case of isolated unilateral lingual nerve injury that occurred during suspension microlaryngoscopy. ⋯ The precise mechanism of injury in this case was not obvious, but stretching of the lingual nerve caused by pressure of the suspended laryngoscope on the tongue or retrolingual region was likely. The transient nature of the injury and the rapid return of the nerve to baseline function in this case are consistent with a neurapraxic injury.
