Maxillary sinus floor elevation in cases of reduced vertical bone height in the posterior maxilla allows predictable implant placement. The osteotome sinus floor elevation (OSFE) technique has shorter healing and waiting times because the fixture can be placed in the implant recipient site simultaneously with the ridge augmentation. Implant site preparation is more comfortable for the patient when performed with spiral drills than with continuous malleting of the osteotomes. Membrane perforation is the most frequent complication with the OSFE technique; postoperative infection is rare. Benign paroxysmal positional vertigo (BPPV) may be a complication of OSFE and may cause stress if not identified correctly and managed properly. The available treatment options, diagnostic strategies and the pathophysiology of this unusual complication are discussed. The authors present a case in which intense BPPV developed during OSFE, focusing on dental and maxillofacial surgery as risk factors for this pathology.
在上颌后牙区牙槽嵴骨量不足时，行上颌窦底提升术可实现种植体的精准植入。骨凿上颌窦底提升术（osteotome sinus floor elevation，OSFE）具有较短的愈合和等待时间，因为在进行牙槽嵴增高的同时可以将种植体固定在种植体植入部位。与连续敲击骨凿相比，使用螺旋钻头进行种植体预备时，患者的舒适度更高。OSFE 技术最常见的并发症是黏膜穿孔；术后感染较为罕见。良性阵发性位置性眩晕（benign paroxysmal positional vertigo，BPPV）可能是 OSFE 的一种并发症，如果不能正确识别和妥善处理，可能会给患者带来压力。本文讨论了这种不常见并发症的治疗选择、诊断策略和病理生理学。作者报告了 1 例 OSFE 术后发生剧烈 BPPV 的病例，重点讨论了牙科和颌面外科手术作为这种疾病的危险因素。
