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.
良性阵发性位置性眩晕（BPPV）是一种相对罕见的病症，其特征是由头部运动或姿势改变引发旋转性头晕。BPPV的病因包括头部损伤、感染、血管疾病、手术创伤和特发性事件。本报告介绍了一例在使用骨凿进行上颌窦底提升并同时植入种植体后发生的持续性BPPV病例。一名49岁女性在使用骨凿进行上颌窦底提升手术植入种植体后立即出现强烈的眩晕和恶心，尤其是在直立时改变头部位置时。尽管使用了抗眩晕药物，但病情并未改善。在转诊给神经耳科医生后，在骨凿上颌窦底提升手术后14天诊断出手术部位对侧的BPPV。随后应用了Epley手法，逐渐地，种植体手术后3个月BPPV症状消失。在进一步的3个月随访中未观察到BPPV复发。本报告对骨凿上颌窦底提升相关BPPV的预防和管理进行了综述。
