Follow Up Study of the Zygoma Complex Fracture Patients along the Inclusion of Coronary Incision as the Approaches

ABSTRACT

Zygoma complex has important roles as the contour, and buttreses in the bony skeleton of the midface. Many surgical approaches to the zygoma complex fractures have been discovered, such as the coronal approach, Gillies' approach and the intraoral approach. 387 patients of zygoma complex fracture from March 1990 to March 2001 in Department of Plastic & Reconstructive Surgery, Dong-A University Hospital were studied retrospectively about deformity of facial contour, enophthalmos, scar etc., divided into two groups, operated with and without coronary approach. The postoperative complications were researched through the charts, X-ray findings and clinical photographs. The coronary approach was used mostly in the case of the severe displacement of fractured bony fragments or neurosurgical emergency(traumatic subdural hematoma, ect.). The group with the coronary approach had higher rate of scar, hypoesthesia and anesthesia than the group without the coronary approach but the coronary approach was thought to be useful considering mostly used in severe zygoma bone fractures and its lower rate of deformity than the group without one, nevertheless there was no statistical significance about the facial deformity between the former(2.6%) and the latter(7.3%). We supposed that these outcome help us to choose more suitable approach in zygoma complex fracture operation.
