Background: The aim of this study was to evaluate the clinical outcomes of implants that were placed within themaxillary sinus that has a perforated sinus membrane by the lateral window approach. Methods: We examined the medical records of the patients who had implants placed within the maxillary sinusthat has a perforated sinus membrane by the lateral approach at the Department of Oral and Maxillofacial Surgeryof Chonnam National University Dental Hospital from January 2009 to December 2015. There were 41 patients(male:female = 28:13). The mean age of patients was 57.2 ± 7.2 years at the time of operation (range, 20?76 years). The mean follow-up duration was 2.1 years (range, 0.5?5 years) after implant placement. Regarding the method ofsinus elevation, only the lateral approach was included in this study. Results: Ninety-nine implants were placed in 41 patients whose sinus membranes were perforated during lateralapproach. The perforated sinus membranes were repaired with a resorbable collagen membrane. Simultaneousimplant placements with sinus bone grafting were performed in 37 patients, whereas delayed placements weredone in four patients. The average residual bone height was 3.4 ± 2.0 mm in cases of simultaneous implantplacement and 0.6 ± 0.9 mm in cases of delayed placement. Maxillary bone graft with implant placement,performed on the patients with a perforated maxillary sinus membrane did not fail, and the cumulative implantsurvival rate was 100%. Conclusions: In patients with perforations of the sinus mucosa, sinus elevation and implant placement are possibleregardless of the location and size of membrane perforation. Repair using resorbable collagen membrane is apredictable and reliable technique.
