Abstract:

Objective  To evaluate the effective of transconjunctival approach in treating orbitozygomatic complex fractures. Methods  Fifty-four transconjunctival incisions were applied to correct enophthalmos and face collapse in 46 patients who suffered by orbitozygomatic complex fractures. All operative procedures were performed with an additional lateral canthotomy (5-10 mm) and 43 of them with gingivobuccal sulcus incisions simultaneously. The infraorbital rim and lateral orbital wall were stabilized with titanium plates. Titanium nets were used to reconstruct the comminuted orbit floor fractures. Results  The bilateral zygomaticas of 46 cases with orbitozygomatic complex fractures were basically symmetric, and the eyeball positions were reset anatomically. The treatment effectiveness were satisfactory. There were no obvious postoperative complications, except one corneal epithelium stripped on the right side and one overtime swelling of conjunctiva which cured after relevant treatments. Conclusion  The transconjunctival approach has good exposure to the orbital floor without visible scar and injury to facial nerve branches, it is a preferable procedure to reconstruct orbitozygomatic fractures.
