The purpose of this study was to evaluate the effectiveness of a new water lift system used as a surgical instrument in the crestal approach of the sinus membrane lifting operation and the capability of this technique to reduce the risk of Schneiderian membrane perforation in comparison with a lateral approach using piezoelectric surgery. 50 sinus membrane-lifting operations were performed. Patients were randomized in 2 groups to receive either lateral sinus elevation with piezosurgery or crestal sinus elevation using the new surgical device. Schneiderian membrane perforation was noted in 6 patients (24%) from the group undergoing the lateral sinus floor elevation approach, but no perforation was observed in the group with the crestal infiltration technique (P=0.01). Aside from membrane perforation, haematoma was present in 3 patients (12%) from the group with lateral sinus floor elevation with no cases in the other group. No microbial infections were noted in the 50 consecutives cases. This study demonstrated that maxillary sinus floor elevation using the water lift system via the crestal approach is a predictable procedure with a low complication rate, compared with the lateral approach with piezoelectric surgery.
本研究旨在评估一种新型水提升系统作为手术器械在窦膜提升手术中的冠向入路的有效性，并比较该技术与使用压电手术的侧向入路相比降低施莱歇尔膜穿孔风险的能力。共进行了 50 例窦膜提升手术。患者随机分为两组，一组接受使用压电手术的侧向窦提升，另一组接受新型手术器械的冠向窦提升。在接受侧向窦底提升术的 6 名患者（24%）中观察到施莱歇尔膜穿孔，但在采用冠向浸润技术的组中未观察到穿孔（P=0.01）。除了膜穿孔外，在接受侧向窦底提升术的 3 名患者（12%）中存在血肿，而在另一组中没有。在 50 例连续病例中均未发生微生物感染。本研究表明，与使用压电手术的侧向入路相比，使用水提升系统通过冠向入路进行上颌窦底提升是一种具有低并发症率的可预测手术。
