AIM: To investigate the importance between several edge points repair through enophthalmos study after orbital wall fracture repair surgery.

METHODS: The date of 23 eyes of 23 cases with medial-inferior orbital wall fracture with enophthalmos were collected and analyzed retrospectively. All cases underwent orbital fracture surgery, the follow-up time was 3mo. After surgery, the degree of enophthalmos was within 2mm. The repair of bony buttress, exterior margin of inferior orbital wall, and superior margin of medial orbital wall after surgery were analyzed.

RESULTS: In these well-recoverd patients, repair rate between bony buttress(100%), exterior margin of inferior orbital wall(43%)and superior margin of medial orbital wall(83%)were different.

CONCLUSION: The repair of bony buttress was most important for surgery. Analysis between surgical efficacy and edge points repair is valuable for surgical operation and risk control.
