Introduction: Maxillary sinus augmentation is a technique widely used to address insufficient bone height in the maxillary posterior region caused by bone resorption and sinus pneumatization. We aimed to reviews the lateral sinus augmentation procedure and identify key factors for success. Materials and Methods: This study included 31 patients who underwent lateral sinus augmentation achieve successful bone graft outcomes without resorption or failure between January 2024 and March 2025. Preoperative and postoperative radiographs and intraoperative photographs were analyzed, and the procedures were compared with those in the existing literature. Results: The incision line and lateral window designs used in this study were consistent with those reported previously. Although this study used the removal and repositioning method for lateral window management, other studies have used grinding and infracture techniques. The use of specialized kits for sinus membrane elevation have been highlighted in some studies for safety and convenience; however, this study demonstrated that a the use of a 45° Freer elevator alone was sufficient. Fibrin glue has been used to improve graft handling and barrier effects during bone grafting and window repositioning, whereas other studies have reported similar success using barrier membranes. Conclusion: Lateral sinus augmentation is essential for implant placement in the posterior maxillary region. The key factors for success include proper incision and window design, careful membrane elevation, appropriate graft selection, and tension-free suturing. When performed correctly, this approach ensures predictable outcomes with results comparable to those achieved using advanced equipment or alternative techniques. KCI Citation Count: 0
