Benign tumors or tumor-like lesions occurring in the base of the maxilla and in the maxillary sinus are routinely extirpated through the canine fossa.<BR>However, complete extirpation may be difficult with the possible risk of recurrence when the lesion is relatively large, as this technique may not permit adequate visualization of the procedure.<BR>Hemimaxillectomy to produce complete extirpation may, on the other hand, produce considerable morphologic as well as functional disturbances. We recently experienced a case of relatively extended osteoma originating in the maxilla. Extirpation was performed by means of the modified Le Fort I osteotomy, usually utilized in the field of orthognathic surgery, with favorable results.<BR>This approach will in the future be considered the operative procedure permitting of choice, extensive lesions removal of even under direct vision and symmetric countenance post-operatively by performing bone grafting into the bone defect site.
