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.
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.
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.
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.
