Lateral sinus-lifting intervention: intraoperative complications and their management

Introduction. Sinus lifting is a commonly used procedure in oral implantology, considered an effective and safe method for increasing bone volume in patients with severe atrophies in the posterior sectors of the maxilla. Despite the high efficiency and safety of maxillary sinus floor elevation, it is not free of complications, both intraoperative and postoperative. Objective. A Systematic Analysis of Scientific Research and Clinical Studies on the Influence of Schneiderian Membrane Perforations on Implant Survival. Results. Of the 1632 initially identified articles, 20 were included in the final analysis. A total of 2837 patients were analyzed, undergoing 3886 lateral access sinus lifting procedures with an average Schneiderian membrane perforation rate of 28.5%. A total of 7755 dental implants were placed, of which 2958 were placed under perforated and repaired membranes, achieving a survival rate of 97.95%, while 4894 implants were placed under intact sinus membranes, achieving a survival rate of 98.38%. Conclusions. Although no statistically significant difference in the survival rates of implants placed under repaired membranes compared to those under intact membranes was observed, there is still a tendency for an increased implant failure rate as the size of the perforations increases.
