摘　　要：目的 探讨伴上颌窦内软组织良性病变的经牙槽嵴顶上颌窦底提升术的可行性。方法 回顾40例伴上颌窦内软组织良性病变且上颌后牙区骨高度不足的病例,经牙槽嵴顶上颌窦底提升术同期种植(未植骨)。术前、术后6个月内及修复后12个月影像学检查,记录上颌窦内情况,整个治疗过程术中、术后并发症及转归。结果 在40例伴上颌窦内软组织良性病变的病例中,根据影像学检查病变形态学特征分为3类,A类:窦底黏膜均匀增厚型14例,未发生术中及术后并发症。B类:囊肿型7例,术中发生上颌窦黏膜穿孔1例。C类:混合型(慢性炎症结合囊肿)19例,术中发生上颌窦黏膜穿孔4例,术后种植体松动脱落2例。结论 尚不可证明上颌窦内软组织良性病变的存在是愈合期内种植体脱落的原因,且病变的存在对修复后1年的种植体无显著影响。通过术前完善的检查与风险预判,术中同期不植骨与术后的感染控制可有效对相关并发症进行风险防控。Objective To evaluate the effect of osteotome sinus floor elevation with maxillary sinus mucosal disease.Methods A total of 40 patients who had maxillary sinus mucosal diseases,with upper posterior teeth loss and bone deficiency were treated by osteotome sinus floor elevation and implant placement.X-ray examination was performed before surgery,6 months after surgery and 12 months after restorations.All the complications and changes in maxillary sinus were recorded.Results According to the X-ray examination,the 40 cases were divided into three categories,A:mucosal thickening(14),no complication,B:cyst(7),1 cystic fluid leakage,C:A+B(19),4 sinus membrane perforations,and 2 implants failure.Conclusions There is no direct evidence that shows maxillary sinus mucosal disease is the reason for implant failure during the healing period,and the presence of the lesion seems no significant impact on the implant after 1-year restoration.
