Abstract: Objective: To compare the clinical effects of two types of operation for patients who had insufficient bone mass in the maxillary posterior region accompanied with maxillary sinus pseudocyst. Methods: Patients were divided into experimental group and control group. In the experimental group, cyst decompression combined with crestal-approach maxillary sinus lifting and implantation was performed simultaneously, while in the control group, cyst decompression combined with lateral-approach maxillary sinus lifting was performed simultaneously. The operation time, postoperative pain and swelling, success rate of implantation, and recurrence rate of cyst were compared between two methods. Results: A total of 34 patients were enrolled in the experiment. The operation time of the experimental group [(27.88±3.02) min] was significantly shorter than that of the control group [(34.94±3.50) min, P<0.001], and the postoperative reaction, including pain (P<0.05) and swelling (P<0.001) was significantly better than that of the control group. The success rate of early implantation was 100%. No cyst recurred in each group. Conclusion: Decompression of cyst in maxillary sinus combined with simultaneous implantation and crestal-approach sinus lifting can significantly shorten the operation time, and the postoperative reaction of patients is significantly reduced with a high success rate of implantation. This method is worthy of clinical promotion.
