Abstract: Following maxillary posterior tooth loss, the residual bone height and width are often compromised due to maxillary sinus pneumatization and alveolar ridge resorption. The lateral window technique for sinus floor elevation is a common procedure to address vertical bone deficiencies in this region. Intraoperative mucoperiosteal perforation is the most frequent complication encountered, posing a challenge for every implant surgeon. This article reviews the diagnosis, causes, treatment strategies, and prevention of mucoperiosteal perforation during lateral window technique for sinus floor elevation, aiming to provide clinicians with practical insights for managing this complication.
