Abstract

Perforation of the Schneiderian membrane during lateral sinus floor elevation is a frequent intraoperative complication that can compromise graft stability and peri-implant health. This technical note describes a modified membrane application technique utilizing an ergonomic “handle” design and fibrin glue for perforation repair and demonstrates its clinical application. A 71-year-old woman with a history of osteoporosis and denosumab therapy experienced membrane perforation during lateral sinus augmentation and simultaneous implant placement at site #26. During the procedure, the sinus membrane was further elevated to reduce the functional defect size. A resorbable collagen membrane was custom-trimmed to include a protruding “handle”, enabling precise, guided insertion over the defect using surgical forceps to prevent inward displacement. A cohesive mass of the synthetic bone graft material, rhBMP-2, and fibrin glue was safely packed into the subantral space, followed by tack-free repositioning and initial stabilization of the lateral bony window using additional fibrin glue. This technique successfully secured the repair site and prevented particle scattering. Compared with conventional approaches, this modified approach may provide superior mechanical stability and simplifies the overall procedure. However, long-term follow-up and histological evaluation are required to confirm the stability and quality of the newly formed bone at the perforated site.
