Simultaneous Transconjunctival and Transantral Approach for Repair of Blowout Fracture by using Medpor Orbital Implant

ABSTRACT

Surgical approaches to blowout fracture have been made through a skin inci-sion in the lower eyelid placed just below the eyelashes[a subciliary pproach], a conjunctival approach, a transantral approach, or a combined approach. Authors repaired the orbital floor fracture through the transconjunctival and transantral approaches simultaneously in 4 patients confirmed orbital floor fracture on CT scan from April to September 1998. Transconjunctival approach could avoid ectropion, lower eyelid retraction and transantral endoscopic orbital floor exploration could allow precise determination of fracture size, location, and replacement of prolapsed tissue and placement of implant over the bony defect. So it was possible to repair with a minimal size of implant and could avoid the complications caused by a too large implant in the posteriorly located orbital floor fracture.
