Perforation of the maxillary sinus membrane is a common complication during maxillary sinus elevation. Intraoperative perforation of the maxillary sinus membrane may complicate the procedure and indirectly lead to implant failure. Timely repair of the perforated maxillary sinus membrane can effectively improve the implant survival rate. This case describes a method of repairing a maxillary sinus membrane perforation with a suture-attached collagen membrane and shows stable repair results at a 31-month follow-up.
