Abstract

Blow-out fractures usually occur at the weakest point of orbital wall such as medial wall or orbital floor. The operative treatment of blow-out fracture involve restoration of intra-orbital soft tissue and bony structural integrity. The surgical reduction of medial blow-out fracture are mainly transcutaneous, transnasal and transconjunctival approaches. The conventional methods has several disadvantages, such as external scar, narrow operative field and injury of neurovascular bundle. But medial transconjunctival approach has advantages such as minimal scar, short operative time and relative safety. We experinced 26 cases of medial blow-out fracture using medial transconjunctival approach from June 2001 to May 2003. Preoperatively 21 cases showed diplopia and 14 cases showed enophthalmos. In postoperative complications, diplopia were 2 cases, enophthalmos was 1 case, anterior displacement of implant were 2 cases, conjunctival scar were 2 cases and injury of caruncle was 1 case. We report the medial transconjunctival approach that was effective treatment for medial blow-out fracture without specific complications.
