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 cm2. 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.
目的
本研究的目的是介绍存在上颌窦假性囊肿时进行上颌窦提升的患者情况、手术过程、并发症及结果。
研究设计
2002年至2005年，109例患者因牙槽骨高度不足无法进行种植体植入而计划接受一期或二期上颌窦底提升术（n = 129）。影像学检查显示存在明显的上颌窦假性囊肿。
结果
8例（7.3%）患者被诊断为上颌窦假性囊肿，2例术前有静止性鼻窦炎病史。在上颌窦下缘发现一个模糊的穹顶状不透光区。平均病变大小为5.09平方厘米。所有种植体在随访时（平均20个月）功能良好。
结论
上颌窦假性囊肿并非上颌窦提升的禁忌证。上颌窦黏膜穿孔和术后鼻窦炎的发生率较低，使手术安全。对于较大病变及诊断不明确的病例，在上颌窦提升术前需要进一步评估。
