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。
目的：評估在保留上頜竇假性囊腫的條件下，進行穿牙槽嵴頂入路的上頜竇底提升的臨床效果。方法：14例患者接受保留上頜竇假性囊腫的穿牙槽嵴頂入路上頜竇底提升術，同期植入種植體，共植入15枚種植體。分彆在術前、術後即刻和術後1年拍攝 CBCT，測量植骨區骨量變化及上頜竇假性囊腫變化。結果：全部手術中無囊腫破裂和上頜竇黏膜穿孔，愈閤期種植體骨結閤良好，隨訪期無種植體脫落。術前上頜竇底剩餘骨高度為（6．85±1．07）mm．術中提升高度為（6．93±2．07） mm。術後竇底提升高度（GBH）為（13．88±1．87）mm、1年後骨愈閤後竇嵴距（GSH-1）（12．76±2．03）mm。隨訪期內，囊腫增大3例，基本不變3例，減小5例，消失3例。結論：上頜竇底提升術的同時保留上頜竇假性囊腫可穫得較滿意療效。

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 ±1.07)mm.The sinus membrane was successfully elevated in all sites without perforation (mean elevation height,6.93 ±2.07)mm.All 15 implants were ossteointegrated.At 1-year revisit the gained bone height was (12.76 ±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.
