Maxillary swing approach to the orbit.

A new surgical approach to the inferior half of the orbit is described and 2 cases are presented. The approach involves releasing the roof and the anterior wall of the maxillary antrum by osteotomies, keeping their blood supply via the attached masseter muscle, and swinging the osteoplastic flap away from the orbit. With the wide exposure gained, the retrobulbar tumor or large orbital floor tumor is dealt with, and the mobilized bone is replaced and wired into position. There is no postoperative disturbance of cosmetic appearance.
