方法：回顾性分析46例眼眶内壁、下壁骨折患者经结膜入路行眶壁骨折整复的手术方法和效果。

结果：术后所有患者视力无明显下降； 在31例复视患者中，术后12mo，3例存在向上方及颞侧极度转动时复视； 23例眼球内陷患者中，术后3～12mo，15例患者双眼眼突度相差≤2.0mm，8例患者术眼低于健眼2.0mm以上； 所有患者外观均无可见的手术瘢痕及外眦畸形。

结论：经结膜入路行眼眶爆裂性骨折整复手术，方法安全可靠，入路简单，操作方便，并发症少，患者面部没有瘢痕。

METHODS: Totally, 46 cases(46 eyes)with fracture on inner and lower orbit wall were treated with transconjunctival approach operation, and the methods and effects were retrospectively analyzed.

RESULTS: All patients had no significant vision loss postoperatively. Among 31 diplopic cases, 12 months after operation, 3 cases existed diplopia with extreme upward and temporal rotation. Among 23 patients with enophthalmos, 3-12 months after operation, 15 patients showed protrusion difference between two eyes less than 2.0mm, and the vision of the operative eye was more than 2.0mm lower than that of the healthy eye in 8 patients. All patients had no visible operative scar and lateral canthus deformity.

CONCLUSION: Transconjunctival operation for treating orbital blowout fracture is safe, reliable and simple, with few complications and no facial scar.
