The intricate and delicate structure of the periorbital region, particularly in pediatric patients, presents challenges to eyelid reconstruction. Much like the more common lower eyelid ectropion, upper eyelid ectropion can result from lack of tissue, scar contracture, or over-resection as in blepharoplasty. In burns and trauma, the cause of cicatricial ectropion is typically direct scar contracture from injuries to the eyelid. However, in some cases, extrinsic wounds involving contracture to the forehead or eyebrow can result in upper eyelid cicatricial ectropion. Direct reconstruction and skin grafting of the eyelid present complex challenges, especially in the acute inflammatory phase of traumatic injury and burn care. Furthermore, in many of these cases the periorbital and lamellae anatomy is preserved, but rather severely displaced due to scar contracture forces. The authors discuss our experience with treatment of extrinsic upper eyelid cicatricial ectropion in a series of 4 pediatric patients with burns or trauma to the forehead and periorbital regions. In all 4 cases, the antegrade foreheadplasty procedure helped to provide globe coverage, while avoiding skin matching difficulties and the intrinsic risks of operating on the eyelid during the acute phase of recovery. There is currently very limited data for the use of this technique to correct such defects. With this study, the authors hope to establish the antegrade foreheadplasty as a reconstructive option for a select patient population.
眼眶区域的结构复杂而精细,尤其是在儿科患者中,这给眼睑重建带来了挑战。与更常见的下眼睑外翻类似,上眼睑外翻也可能是由于组织缺失、瘢痕挛缩或如眼睑成形术那样的过度切除引起的。在烧伤和创伤中,瘢痕性外翻的原因通常是眼睑受伤直接导致的瘢痕挛缩。然而,在某些情况下,涉及额部或眉毛的外在伤口会导致上眼睑瘢痕性外翻。眼睑的直接重建和植皮术带来了复杂的挑战,尤其是在创伤性损伤和烧伤护理的急性炎症阶段。此外,在许多这些情况下,眼眶和睑板的解剖结构得以保留,但由于瘢痕挛缩的力量,位置严重移位。作者讨论了我们在 4 例因额部和眼眶区域烧伤或创伤的儿科患者中治疗外在性上眼睑瘢痕性外翻的经验。在所有 4 例中,额部前向成形术有助于提供眼球覆盖,同时避免了皮肤匹配困难以及在恢复的急性期对眼睑进行内在操作的内在风险。目前,这种技术用于矫正此类缺陷的相关数据非常有限。通过这项研究,作者希望将额部前向成形术确立为一种适合特定患者群体的重建选择。
