Asymmetry of the infraorbital rim can be caused by trauma, congenital or acquired disease, or insufficient reduction during a previous operation. Such asymmetry needs to be corrected because the shape of the infraorbital rim or midfacial skeleton defines the overall midfacial contour.
The study included 5 cases of retruded infraorbital rim. All of the patient underwent restoration of the deficient volume using polyethylene implants between June 2005 and June 2011. The infraorbital rim was accessed through a subciliary approach, and the implants were placed in subperiosteal space. Surgical outcomes were evaluated using preoperative and postoperative computed tomography studies.
Implant based augmentation was associated with a mean projection of 4.6 mm enhancement. No postoperative complications were noted during the 30-month follow-up period.
Because of the safeness, short recovery time, effectiveness, reliability, and potential application to a wide range of facial disproportion problems, this surgical technique can be applied to midfacial retrusion from a variety of etiologies, such as fracture involving infraorbital rim, congenital midfacial hypoplasia, lid malposition after blepharoplasty, and skeletal changes due to aging.
眶下缘不对称可由外伤、先天性或后天性疾病引起，或因先前手术中复位不充分所致。由于眶下缘或面中部骨骼的形状决定了整个面中部轮廓，因此这种不对称需要矫正。
该研究纳入了5例眶下缘后缩患者。2005年6月至2011年6月期间，所有患者均使用聚乙烯植入物修复了缺损容积。通过睫毛下切口进入眶下缘，将植入物置于骨膜下间隙。使用术前和术后计算机断层扫描研究评估手术效果。
基于植入物的隆突平均增强投影为4.6毫米。在30个月的随访期内未发现术后并发症。
由于该手术技术具有安全性、恢复时间短、有效性、可靠性以及可应用于广泛的面部不对称问题，因此可应用于多种病因导致的面中部后缩，如涉及眶下缘的骨折、先天性面中部发育不全、眼睑成形术后眼睑位置异常以及衰老引起的骨骼变化。
