From March 1997 to August 2001, Titanium mesh screen 1.0 (SYNTHES(R)) were applied to the repair of 29 medial orbital fractures; 18 patients with orbital inferior wall fracture, 16 patients with nasal bone fracture and 6 patients with pure medial wall fracture. Clinically, the periorbital ecchymosis and subconjunctival hemorrage were sensitive indications of orbital wall fracture. Even though there are no sign of diplopia or enophthalmos, in cases of simple nasal bone fracture with periorbital ecchymosis and subconjunctival hemorage, the evaluations of medial orbital wall fracture were strongly recommended because the medial orbital wall fractures occurred frequently combined with simple nasal bone fractures. Titanium mesh screen 1.0 was used as onlay implant to fit the anatomical shape on the fracture portion needed to be reconstructed and 1.3mm microscrews (SYNTHES(R)) were used to fix titanium mesh screen. The patients were followed up for 18 months with no significant enophthalmos or diplopia.
