Surgical repair of medial orbital wall combined with orbital floor fracture via lower lid subciliary approach / 眼科

ABSTRACT

Objective To assess the effect of surgical repair of medial orbital wall combined with orbital floor fracture via lower lid subciliary approach. Design Retrospective case series. Participants 18 cases of medial orbital wall combined with orbital floor fracture. Methods All patients underwent the reconstruction of orbital wall via lower lid subciliary approach. The composite hydroxyapatite was implanted into the surface of medial orbital wall and orbital floor after lacriminal cyst was completely dissected and protected during the operation. Orbital axial and coronal CT, three-dimension CT scan have been used in all the cases preoperalively and postoperatively. Preoperative CT was compared with postoperative CT. Main Outcome Measures Clinical symptoms and complications. Results All patients were followed up for 3 to 18 months. The postoperative scar of infracillary skin was not obvious. The composite hydroxyapatite was not rejected and dislocated in all cases postoperatively. No postoperative epiphora was found in either case. Preoperative diplopia and enophthalmos were corrected. Conclusion The treatment of medial orbital wall combined with orbital floor fracture via an isolated lower lid subciliary approach was feasible. But the incision was only used in the treatment of inferior medial orbital wall combined with orbital floor fracture, especially the transition area fracture between the orbital floor and medial orbital wall.
