Analysis of the Improvement of Post-Traumatic Enophthalmos after Surgery

ABSTRACT

From 1996 to 2003, we reviewed 16 enophthalmos cases including 7 males(age 25 to 72 years) and 9 females (age 24 to 32 years) who have been treated in the Department of Plastic and Reconstructive Surgery, Guri and Seoul Hospital Hanyang Medical Center. We categorized the pattern of the facial bone fracture corresponding intra-orbital lesions and the operative methods(approaches and implant positioning) according to each lesions in the orbit. In preoperative and postoperative axial CT view, we measured the amount of exophthalmos at the orbital apex level. The most severe enophthalmos was observed in inferior and lateral wall defect and the differences between both globes was 5mm in CT measurement. In CT measurement, the most improved lesion was medial wall(3mm protrusion) and secondary most improved lesion was 4-wall-combined orbital lesion(2.7mm protrusion). In the other cases showed less 2mm differences in CT measurement except inferior and lateral wall lesion which showed 2.5mm difference. When the implant was located posterior to the mid-coronal line of globe, the mean improvement (2.16mm) was higher than other cases(1.7 mm).
