AIM: To investigate the clinical effect of reconstruction of orbital blowout fracture by conjunctival incision combined with Medpor Titan implantation under nasal endoscopy.

METHODS: Sixteen patients(16 eyes)diagnosed with orbital blowout fracture, include medial fractures, floor fractures and extended fractures, were performed reconstruction by transconjunctival approach with implant material- Medpor Titan under nasal endoscopic-assisted; observation of postoperative visual acuity, eyeball protrusion, extraocular movement limitations, diplopia, orbital CT, occurrence of implanted material rejection was taken.

RESULTS: A 3-month follow-up was performed and the therapeutic efficacies of anatomic and functional recovery were evaluated. No further vision loss or infection occurred postoperatively. In the 16 patients, the average postoperative observation was 3mo, enophthalmos were fully corrected, diplopia disappeared. Orbital(CT)did not reveal implant displacement and rejection postoperatively.

CONCLUSION: Endoscopic-assisted reconstruction of orbital blowout fracture by conjunctival incision combined with Medpor Titan implantation is a safe and effective surgical method with the characteristics of with direct operation, clear range of fracture exposure and safe and reliable operation, not only restores the patient's visual function and appearance, but also reduces the incidence of complications, avoiding postoperative facial scar.
