When operating in and around the orbit, the key to a successful operative result is precise, anatomic localization. This study was constructed to give pertinent anatomic measurements to which the maxillofacial surgeon may refer. The safe distances noted from this study are: 1) medially 30 mm from the anterior lacrimal crest; 2) inferiorly 25 mm from the infraorbital foramen; 3) superiorly 30 mm from the supraorbital notch; and 4) laterally 25 mm from the frontozygomatic suture.
