Analysis for prolonged postoperative diplopia in orbital floor fracture

Objective To analysis the failure reasons for surgical treatment in orbital floor fracture.Methods The retrospective analysis comprised 12 cases of prolonged diplopia after repair for orbital floor fracture.Results 12 patients with orbital floor fracture showed vertical diplopia and enophthalmos and underwent surgery.Postoperatively,exacerbation and prolonged diplopia showed in all cases.9 cases suffered from incomplete dissection of herniated sofe tissue into posterior fracture site,even surgical incarceration ; 2 cases suffered from upward dystopia,for the reason of failure to place implantment posterior to the equator of the globe,and 1 pediatric patient,whose failure caused possibly by muscle' s adhesion and shift of orbital fracture.Conclusion Adquate fracture reduction,correct implant placement,and preventment for adhesion are important for surgical repairment of orbital fracture.
