title: Protracted benign paroxysmal positional vertigo following osteotome sinus floor elevation: a case report.
abstract: Benign paroxysmal positional vertigo (BPPV) is a relatively rare condition characterized by onset of rotation dizziness triggered by head movements or change in posture. BPPV etiology includes head injury, infection, vascular disorders, surgical trauma, and idiopathic events. This report presents a case of protracted BPPV following osteotome sinus floor elevation and simultaneous implant placement. A 49-year-old female suffered intense vertigo and nausea immediately after implant placement using an osteotome sinus floor elevation procedure, especially when changing head position while sitting upright. Despite antivertigo medications, the condition did not improve. Following referral to a neurotologist, BPPV contralateral to the operation site was diagnosed 14 days after the osteotome sinus floor elevation procedure. The Epley's maneuver was then applied and, gradually, symptoms of BPPV disappeared 3 months after the implant surgery. No recurrence of BPPV was observed during further 3-month follow-up. Prevention and management of osteotome sinus floor elevation-related BPPV are reviewed in this report.
