The presence of septa in the region of the sinus floor can cause complications during sinus lift procedures; accordingly, it is necessary to identify the sinus septa prior to the operative procedure. Various treatment options have been described for management of septa. This study described three cases of lateral window approach for maxillary sinus bone graft in the presence of sinus septa. Panoramic radiograph and dental cone-beam computed tomographic scans were obtained preoperatively. In the first and third case, two bony windows were created after infracture, while in one case the septal bone was cut off and in the other it was left intact. In the second case, one bony window was prepared and the sharp tip of the septum was reduced. After treatment, all of the cases achieved sufficient bone height and no membrane perforation occurred. Modification of the basic sinus lateral approach is a predictable technique to increase bone volume of the edentulous posterior maxilla; therefore, it can be used for placement of dental implants.
