    Abstract:
    OBJECTIVE: To investigate the clinical outcomes following early repair for orbital fracture and soft tissue simultaneously for open orbital fractures. METHODS: Retrospective clinical study. This study comprised of 19 patients(20 eyes) with open orbital fracture who underwent surgery within 48 hours in the Second Hospital of Dalian Medical University between August 2011 and August 2014. The wounds were evaluated at the same time and the surgical debridement was done. The surgical exposure was achieved through direct approach and auxiliary cosmetic incisions. Titanium mesh and plate was used for orbital reconstruction. Local flaps or island flaps were used for soft tissue repair. With the post-operative CT scan, the condition of the soft tissue which was herniated, the orbital rim and orbital wall were observed. The measurement of the exophthalmos of both eyes was performed using Hertel exophthalmometer. Compared with the intact eye, the globe displacement (upward or downward) of the reconstructed eye was measured. The follow up duration was 12-24 months. The eye movement, diplopia, restriction of mouth opening, depression of midface, the condition of soft tissue and scar as well as post-operative complications were recorded. Comparison of the reconstructed eye's globe displacement before and after operation were analyzed with wilcoxon signed ranks test. Comparison of the exophthalmos of the reconstructed eye relative to the intact eye were analyzed with t-paired test. RESULTS: In all 19 cases (20 eyes), fractures were anatomically reconstructed, and no cases of infection, titanium mesh and plate migration and rejection occured during the follow-up. Seven cases had eyeball hypoglobus with median 3.0 mm (min 2.0 mm, max 4.0 mm) pre-operatively. The Reconstructed eye globe were corrected in 6 cases and 1 case had residual hypoglobus of 1.0 mm ,median 0.0 mm (min 0.0 mm, max 1.0 mm). The amount of the eye globe displacement between pre-and post-operation was statistically significant(z=-2.40, P<0.05). Enophthalmos was corrected in 16 cases (the mean of posterior globe displacement in reconstructed orbit relative to intact orbit was less than or equal to 2.0mm), but in 2 patients the residual enophthalmos was 3.0 mm. The difference of the exophthalmos of both eyes was not obvious (t=-0.46,P>0.05). Among 20 eyes, 16 patients had restrictive eye movement. After 12 months follow-up, 13 eyes with restrictive eye movement were corrected while the other 3 showed improvement. Eight patients of restriction of mouth opening or midface depression were corrected and no infection complications were noted. There was no flap necrosis in 13 patients of soft tissue defect. CONCLUSION: Surgical treatment of open orbital fractures with simultaneous repair of orbital fracture and soft tissue within 48 hours after trauma could correct enophthalmos, hypoglobus and eye movement function effectively and improve periorbital aesthetics.
