The transconjunctival, subciliary, subtarsal, and subpalpebral approaches for accessing the infraorbital rim and orbital floor have both advantages and disadvantages. The most common complications include rounding of the lateral canthal angle, lower eyelid retraction with inferior scleral show, and frank ectropion.
From 2000 to 2007, we treated 29 patients with lower eyelid malposition after surgery to manage the floor and infraorbital trauma (22 subciliary approaches, five transconjunctival approaches and lateral canthotomies, and two transconjunctival approaches). To correct lower eyelid malposition, we applied the tarsal strip technique in all patients.
Twenty-five patients had scleral show and four patients had ectropion: three were previous treated using transconjunctival access and one using subciliary access. Twenty-six patients obtained satisfactory correction of eyelid malposition in a single-step surgical procedure, while three patients required a second surgical step to correct the remaining scleral show. Good aesthetic and functional results were achieved in all cases.
All approaches to the infraorbital rim or orbital floor have the potential for postoperative sequelae. The tarsal strip technique is a relatively simple technique that oral and maxillofacial surgeons can use to manage lower lid malposition, such as scleral show and ectropion.
经结膜、睑缘下、睑板下及睑皮下入路用于显露眶下缘和眶底均有其优缺点。最常见的并发症包括外眦角变圆、下睑退缩伴下方巩膜外露以及明显的睑外翻。
2000年至2007年,我们治疗了29例因眶底和眶下缘外伤手术后出现下睑位置异常的患者(22例采用睑缘下入路,5例采用经结膜入路联合外眦切开术,2例采用经结膜入路)。为矫正下睑位置异常,我们对所有患者均应用了睑板条技术。
25例患者有巩膜外露,4例患者有睑外翻:3例曾采用经结膜入路治疗,1例采用睑缘下入路治疗。26例患者在单次手术中获得了满意的睑位置异常矫正效果,而3例患者需要进行第二步手术以矫正残留的巩膜外露。所有病例均取得了良好的美学和功能效果。
所有显露眶下缘或眶底的入路均有术后出现后遗症的可能。睑板条技术是一种相对简单的技术,口腔颌面外科医生可用于处理下睑位置异常,如巩膜外露和睑外翻。
