Abstract: This article introduces a surgical approach for the simultaneous management of maxillary sinus cysts and sinus floor elevation using the double-window technique. The first lateral window is created to elevate the Schneiderian membrane and establish space for bone augmentation. Once the membrane is fully elevated and remains intact, a second small lateral window is created above the first to remove the cyst. The two windows are separated to prevent contamination of the graft material by the cystic contents. Additionally, a conservative surgical approach for the palliative treatment of sinus cysts is presented. Three representative cases are described to demonstrate specific techniques and surgical methods.
