钛网支架修复眶底缺损

目的：探讨经头皮冠状切口或睑结膜切口入路，应用钛网支架重建眶底缺损的临床疗效。方法根据CT扫描和三维成像诊断，对18例眶底缺损患者进行微型钛网内固定术重建眶底缺损，其中10例为眶底伴邻近颅面骨折，采用头皮发际内冠状切口；8例为陈旧性眶底骨折，采用睑结膜切口。结果18例患者的眼球内陷和部分合并颧骨骨折的状况得到纠正，切口均愈合良好，切口位置较隐秘或未遗留瘢痕，颜面畸形得到明显改善。术后随访3～24个月，钛网支架无1例松动或移位或者其他并发症，疗效满意。结论头皮冠状切口入路以及睑结膜入路都能为术者提供足够视野与操作空间，应用微型钛网内固定术可重建眶底缺损，防止复视，术后美观效果佳。

The application of titanium mesh in the repair of orbital floor defection

Objective To explore the clinical efficacy of reconstruction of orbital floor defect through coronal scalp approach or conjunctivas approach by using titanium mesh . Methods According to CT scans and three-dimensional imaging diagnosis , reconstructions of orbital floor defect were performed on 18 patients using titanium mesh . 10 cases of orbital floor defection complicated with adjacent craniofacial fractures , the patients were operated through coronary incision in the hairline scalp, while 8 cases of old orbital floor fractures were treated through eyelid conjunctiva incision . Results Enophthalmos were corrected in all 18 cases , so did some patients accompanied with zygomatic fractures. All incisions were covert and healed well without obvious scar, and facial deformity has been obviously improved. All patients were followed up for 3 to 24 months. An acceptable clinical efficacy was obtained, and titanium mesh loosening or other complications were not observed. Conclusions Coronal scalp or conjunctivas incision can provide adequate operating space for surgeons . Orbital floor fracture could be reconstructed by using titanium mesh , which resulted in a better aesthetic effect.
