摘　　要：目的:评估在保留上颌窦假性囊肿的条件下,进行穿牙槽嵴顶入路的上颌窦底提升的临床效果。方法:14例患者接受保留上颌窦假性囊肿的穿牙槽嵴顶入路上颌窦底提升术,同期植入种植体,共植入15枚种植体。分别在术前、术后即刻和术后1年拍摄CBCT,测量植骨区骨量变化及上颌窦假性囊肿变化。结果:全部手术中无囊肿破裂和上颌窦黏膜穿孔,愈合期种植体骨结合良好,随访期无种植体脱落。术前上颌窦底剩余骨高度为(6.85±1.07)mm.术中提升高度为(6.93±2.07)mm。术后窦底提升高度(GBH)为(13.88±1.87)mm、1年后骨愈合后窦嵴距(GSH-1)(12.76±2.03)mm。随访期内,囊肿增大3例,基本不变3例,减小5例,消失3例。结论:上颌窦底提升术的同时保留上颌窦假性囊肿可获得较满意疗效。Objective：To evaluate the clinical outcome of transcrestal maxillary sinus floor elevation（TMSFE）in the presence of pseudocyst.Methods：14 cases with pseudocyst were treated by TMSFE.In the operation following osteotome,pseudocyst was not ex-cised and sinus floor membrane was elevated,15 implants were placed for the 14 cases.Definite prosthesis was delivered about 6 months after implant placement.CBCT examination was done before,immediately after and 1-year after surgery,the cyst condition, the gain of vertical bone height and implant stability over time were observed.Results：Pre-operation residual ridge height of the alveo-lar crest was （6.85 ＆#177;1.07）mm.The sinus membrane was successfully elevated in all sites without perforation （mean elevation height,6.93 ＆#177;2.07）mm.All 15 implants were ossteointegrated.At 1-year revisit the gained bone height was （12.76 ＆#177;2.03）mm. Cyst grew bigger in 3 cases,not changed in 3 cases,became smaller in 5 cases and disappeared in 3 cases.Conclusion：Pseudocyst excision is not necessary in TMSFE.
