Minimally Invasive Lateral Approach through Circular Window with a Diameter of 5 to 6 mm for Maxillary Sinus Floor Elevation with Simultaneous Implant Placement: Retrospective Study

The aims of this study were to propose a minimally invasive lateral approach technique for maxillary sinus floor elevation (MSFE) with simultaneous implant placement and evaluate the surgical outcome complications technique. This reviewed 49 surgeries MSFE (n = 83) using approach. A circular shape window diameter 5 6 mm an area 20–30 mm2 was made on wall sinus. After Schneiderian membrane, xenograft used bone grafting. possible minimum-sized in 47 cases. For remaining 2 cases, failed. In one case, it expanded be more than 30 repair membrane perforation. another performed by forming two windows. Post-operative bleeding after occurred anticoagulant-treated patient. There no failed during follow-up period (mean 22 months). through small is feasible safe placement.
