Three-Dimensionally Preformed Titanium Mesh Plates For Posttraumatic Complex Orbital Bone Fracture Reconstruction 1. Xiaoping Bi Department of Ophthalmology, Shanghai Ninth People's Hospital affiliated to Shanghai Jiaotong University, School of Medicine, Shanghai, PR China Purpose To evaluate the outcomes of the clinical application of three-dimensionally preformed titanium mesh plates for posttraumatic complex orbital bone fracture reconstruction. Methods Total of 13 patients (13 eyes) manifested with complex orbital fracture underwent the reconstructive surgery by using three-dimensionally preformed titanium mesh plates, including orbital-zygomatic- maxillary bone fracture in 6 patients, nasal-orbital-ethmoid bone fracture in 5 cases and the other 2 patients with complex multiple peri orbital bone fracture. 8 cases underwent high density porous polyethylene implantation simultaneously. Evaluation of enophthalmos , eyeball movement and orbit CT scan were taken pre operation. Results The average enophthalmos was（3.9±1.73）mm and the position of affected eyeball was average（3.1±2.56）mm bellow the contralateral side pre operation. There were 12 patients suffered from eyeball movement restriction, including gradeⅠin 4 cased, grade Ⅱ in 7 cases and grade Ⅲ in 2 patients. During 3 to 6 months follow up post operation enopthehalmos were completely corrected in 10 patients while other 3 patients had residual 1mm enopthehalmos. The affected eyeball was repositioned in 8 cases while 3 patients had residual 1mm lower position and 2 patients with 1mm higher positioned eyeball. Totally 8 patients had no restriction of movement of their eyeballs while 3 patients had grade Ⅰmovement restriction and 2 patients had grade Ⅱ restriction. There were no exclusion，infection and other complications during follow up. Conclusions Three-dimensionally preformed titanium mesh plates can be used to reconstrcut posttraumatic complex orbital bone fracture, to improve the orbital volume and to correct enopthehalmos effectively. |
