Versatile use of extended transconjunctival approach for orbital reconstruction.

Abstract

When exposing the orbit, the transconjunctival approach is regarded to have limited surgical exposure. The aim of this study is to demonstrate the versatile usability of extended transconjunctival approach, which can be extended medially and laterally, in reconstruction of medial orbital wall, floor, and even the lateral rim in maxillo-malar complex fracture.We reviewed 122 cases of orbital fractures treated with extended transconjunctival approach. The operative results were assessed by postoperative CT scan and reviewing postoperative complications. The extended transconjunctival approach provided sufficient surgical exposures in all cases. There was no ectropion or scleral show during follow-up period. The cutaneous scars were almost invisible in most cases.The extensile character of this approach makes continuous exposure of the orbit from frontozygomatic suture laterally to the frontonasal suture medially, while minimizing scar and eyelid complications.
