Background: Lower eyelid rejuvenation can, unfortunately, induce scleral show even if the lower eyelid procedure is limited. This study was designed to assess the effectiveness and reliability of the concentric malar lift technique in two scenarios: the first, in rejuvenation of the mid-face and, the second, in reconstructive surgery for correction of congenital or acquired eyelids malposition.

Methods: The concentric malar lift technique was first published by Le Louarn (Aesthet Plast Surg 28(6):359–372, 2004). This retrospective study was carried out by analyzing data on patients operated on between January 2010 and January 2016. Patients operated on before 2010 were excluded because barbed thread sutures were not used in the first version of the technique. Patients after January 2016 were excluded to ensure adequate follow-up, and so 342 patients are included in the study. A total of 256 cases (75%) were for aesthetic mid-face lifting, and 86 cases (25%) were reconstructive surgeries for lower eyelid retraction. A spacer graft was used in 30 of these reconstructive cases (35%). The mean follow-up time was 13.6 months. All the concentric malar lifting procedures included strengthening the lateral canthus, which is a key element of the procedure.

Results: None of the patients developed secondary eyelid malposition, and all the cases of lower eyelid retraction displayed marked improvement both functionally and aesthetically. Two patients experienced loss of sensitivity of part in the infra-orbital nerve distribution for 4 months after the procedure.

Conclusion: The concentric malar lift procedure enables the recruitment of a significant amount of skin into the lower eyelid: between 10 and 30 mm. It ensures better rejuvenation of the mid-face with minimal risk of lower eyelid malposition. In reconstruction of the lower eyelid lid, the concentric malar lift is able to reduce the need for skin grafting and a skin flap reducing the risks of visible scarring.

背景：不幸的是，即使下眼睑手术有限，下睑年轻化也会导致巩膜露出。本研究旨在评估同心颧骨提升术在两种情况下的有效性和可靠性：第一种是面中部年轻化，第二种是先天性或获得性眼睑错位的整形手术。

方法：同心颧骨提升术最早由Le Louarn发表(Aesthet Plast Surg 28(6)：359-372,2004)。这项回顾性研究是通过分析2010年1月至2016年1月期间接受手术的患者的数据进行的。2010年前手术的患者被排除在外，因为该技术的第一个版本中没有使用带刺线缝合法。2016年1月之后的患者被排除在外，以确保有足够的随访，因此342名患者被纳入研究。美容正中提升术256例(75%)，下睑退缩重建术86例(25%)。在这些重建病例中有30例(35%)使用了间隔移植物。平均随访时间13.6个月。所有同心式颧骨提升手术都包括加强外侧眼角，这是手术的一个关键因素。

结果：无一例发生继发性眼睑错位，所有下睑退缩病例在功能和美观上均有明显改善。2例患者术后4个月眼眶下神经分布部分失去敏感度。

结论：同心颧骨提升术能使大量皮肤重新进入下睑：10-30 mm。它可以确保面部中部更好地恢复活力，同时将下眼睑错位的风险降至最低。在下睑重建术中，同心颧部提升术可以减少植皮和皮瓣的需要，降低可见疤痕的风险。
