Objective.本研究的目的是介绍存在上颌窦假性囊肿的鼻窦提升患者的手术过程、并发症和结果。研究设计。从2002年到2005年，109例患者因牙槽骨高度不足以放置种植体而计划进行一期或二期上颌窦底提升（n = 129）。影像学上显示一个明显的胃窦假性囊肿。在8例（7.3%）患者中，诊断为窦假性囊肿，2例术前发现有非活动性鼻窦炎病史。在上颌窦下缘发现一个微弱的圆顶形不透射线性。平均病变尺寸为5.09厘米（2）。所有种植体在随访时（平均20个月）功能良好。上颌窦假性囊肿不是上颌窦提升术的禁忌症。鼻窦黏膜穿孔及术后鼻窦炎发生率低，手术安全。对于较大的病变和诊断不明确的病例，在窦提升之前需要进一步评估。
Objective. The objective of this study is to present patients with sinus augmentation in the presence of an antral pseudocyst and the surgical procedure, complications, and outcome.Study design. From 2002 to 2005, 109 patients were scheduled for 1- or 2-stage maxillary sinus floor augmentation (n = 129) because of inadequate alveolar bone height for implant placement. Radiographically, a significant antral pseudocyst was shown.Results. In 8 (7.3%) patients, an antral pseudocyst was diagnosed, and in 2 a history of inactive sinusitis was found preoperatively. A faint dome-shaped radiopacity was found at the lower border of the maxillary sinus. Average lesion size was 5.09 cm(2). All implants functioned well at follow-up (mean 20 months).Conclusion. A pseudocyst of the maxillary sinus is not a contraindication for sinus augmentation. The low frequency of sinus membrane perforation and postsurgery sinusitis make the operation safe. In large lesions and in cases with an unclear diagnosis, further evaluation is needed before sinus augmentation.
