Abstract

Study design: Prospective Interventional study.

Objective: To evaluate the efficiency of Matrixmidface preformed Orbital plates for three-dimensional reconstruction of orbital floor and medial wall fractures.

Methods: This prospective institutional clinical study was conducted on a group of 14 patients who underwent repair of orbital floor and medial wall fracture defects using Matrixmidface Preformed Orbital plates and open reduction and internal fixation of associated fractures. The following parameters were studied preoperative and postoperative enophthalmos, hypoglobus, orbital volume; correction of diplopia, intraoperative and postoperative complications.

Results: All 14 patients were males aged between 19 and 42 years. The most common mode of injury was found to be road traffic accidents (RTAs) followed by self-fall and trauma at workplace. Orbital fractures were associated with other concomitant maxillofacial fractures in 12 patients (85.7%) while 2 patients (14.3%) had pure blowout fractures. Significant improvement of enophthalmos was noted from preoperative period to 1 week, 6 weeks, and 6 months postoperatively (P value .02, .01, and .01, respectively). Out of 11 patients with preoperative hypoglobus, 5 patients (45.45%) had persistent hypoglobus in the immediate postoperative period which reduced to 4 patients (36.36%) at 6 weeks postoperatively (p value .00). The postoperative orbital volume of fractured side ranged from 20.3 cm3 to 26.76 cm3 with a mean of 23.50 cm3 ± 1.74. The mean difference between the volumes of the repaired and uninjured sides was found to be .27 cm3 ± .39 (P value .02) denoting that the reconstruction of the orbit closely approximated that of the uninjured side.

Conclusions: The Matrixmidface Preformed Orbital plate provides exceptional reconstruction of the orbital blowout fracture defects and ensures satisfactory results clinically and radiographically. The plate ensures an approximate recreation of topographical anatomy of the orbit and adequately restores the orbital volume. It provides adequate correction of asymmetry, hypoglobus, enophthalmos and attempts to restore eye movements, without causing any significant postoperative complication.

Matrixmidface 预成型眼眶植入物用于眼眶底部和内侧壁骨折的三维重建:前瞻性临床研究
研究设计前瞻性介入研究:评估 Matrixmidface 预成型眶板用于眶底和内侧壁骨折三维重建的效率:这项前瞻性机构临床研究的对象是14名使用Matrixmidface预成型眶板修复眶底和内侧壁骨折缺损,并对相关骨折进行切开复位和内固定的患者。对以下参数进行了研究:术前和术后眼球突出、眼睑下垂、眼眶体积、复视矫正、术中和术后并发症:14 名患者均为男性,年龄在 19 至 42 岁之间。最常见的受伤方式是道路交通事故,其次是自摔和工伤。12名患者(85.7%)的眼眶骨折同时伴有其他颌面部骨折,2名患者(14.3%)为单纯的爆裂性骨折。从术前到术后 1 周、6 周和 6 个月,眼球震颤均有明显改善(P 值分别为 0.02、0.01 和 0.01)。在术前眼球突出的 11 位患者中,有 5 位患者(45.45%)在术后即刻出现持续性眼球突出,而在术后 6 周时减少到 4 位患者(36.36%)(P 值为 0.00)。骨折侧的术后眼眶体积从 20.3 cm3 到 26.76 cm3 不等,平均为 23.50 cm3 ± 1.74。修复侧和未受伤侧的平均体积差为 0.27 cm3 ± 0.39(P 值 0.02),这表明眼眶的重建与未受伤侧的重建非常接近:Matrixmidface 预成型眼眶钢板可为眼眶井喷骨折缺损提供出色的重建效果,并确保在临床和影像学上获得令人满意的结果。该钢板可确保近似再现眼眶的地形解剖结构,并充分恢复眼眶容积。它能充分矫正不对称、眼球过小、眼球凹陷,并尝试恢复眼球运动,而不会引起任何明显的术后并发症。
