Abstract: Objective: To discuss and compare the effects of piezosurgery and endoscopic assistance in the treatment of large jaw cysts involving the maxillary sinus. Methods:  72 patients of large jaw cyst with infringement of maxillary sinus from July 2007 to March 2015 were divided into two groups and retrospectively reviewed. Group A（n=36）, the piezosurgery and nasal endoscopic measures were collectively used. The jaw cysts were completely removed with preservation of the normal mucosa of maxillary sinus and contour of maxillary bone. Group B（n=36） a part  of maxillary bone was cleaned by osteotome and bone forceps. The cyst wall was curetted, then the patients were underwent Caldwell-Luc operation. After a follow-up of 3-72 months, the postoperative complications were recorded for assessment. Chi-square test and SPSS 13.0 software package were used for statistical analysis. Results: The incidence of postoperative complications such as maxillary sinus fistula, facial deformity, and nasal obstruction in group A were significantly lower than that in group B（P＜0.05）. The recovery of facial contour and masticatory function were better in group A patients. Conclusion: Piezosurgery and nasal endoscopic assistance in the treatment of large jaw cysts involving the maxillary sinus can effectively decrease the postoperative complications.

摘要： 目的：探讨侵犯上颌窦的大型颌骨囊肿的治疗和临床效果。方法：回顾2007-07—2015-03期间，在本院治疗的72例侵犯上颌窦的颌骨囊肿患者。A组（n=36）术中联合用超声骨刀和鼻内镜，彻底清除病变组织，保存正常窦内黏膜及骨骼外形；B组（n=36）术中用骨凿、咬骨钳去除骨壁，摘除囊壁组织后用刮匙搔刮囊腔及行上颌窦根治术。术后随访观察3～72个月，对术后并发症进行对比观察和统计学分析。采用SPSS13.0软件包对数据进行χ2检验。结果：A组患者在上颌窦瘘、面部畸形、鼻通气功能方面，术后并发症发生率显著低于B组（P＜0.05）；颌面部的美观和功能恢复良好。结论：术中用超声骨刀和鼻内镜治疗侵犯上颌窦的大型颌骨囊肿，保存正常窦内黏膜及骨骼外形，可明显降低上颌窦瘘和鼻通气下降的发生，颌面部的美观和功能恢复较满意。
