ABSTRACT
The term of blow-out fracture refers to a fracture of an orbital wall, typically the orbital floor or medial wall. Especially the medial blow-out fracture is difficulty to approach. Transcutaneous approaches could remain postoperative scars and transconjunctival approaches could give bad visual field and technically difficulties in approaching the medial orbital wall. But the medial transconjunctival incision could avoid an external scar, save the operating time, and decrease injuries of surrounding tissue. Authors operated the medial blow-out fractures through the medial transconjunctival approach and porous high-density polyethylene sheet was placed on fracture site for the prevention of relapse of the orbital contents. 30 cases of medial blow-out fractures were treated using the medial transconjunctival incision. All patients were corrected satisfactorily without leaving any visible scar. Thus the medial transconjunctival approach was an effective way to repair medial blow-out fracture.
