Although the subcilliary or conventional transconjunctival approach has been widely used, it often fails to get acceptable visual fields or scars. This study directly compared the extended transconjunctival approach accompanied by lateral paracanthal incision with other traditional approaches in terms of surgical fields, the outcomes and complications. This retrospective chart review included 113 patients (82 males and 31 females; mean age: 38.7 years; range: 11-87 years), who underwent orbital reduction from November 2009 to September 2013. In extended transconjunctival approach, the external skin of the inferolateral canthal tendon was demarcated in a natural skin crease approximately 5 mm from the lateral canthus. The surgical approach was based on anteroseptal transconjunctival dissection. Paracanthal incision about 5 mm in length was performed. Esthetic and functional complications were evaluated, including the presence of a visible scar, lid retraction, or hypertrophic scar; epiphora, diplopia, global hematoma, persistent enophthamos, or exophthamos; and presence of entropion/ectropion. The extended transconjunctival approach resulted in a significant increase in the area of the surgical field statistically significant (P = 0.002). Complication rates are similar with other approach techniques. Postoperative scarring was confirmed by pictures taken in the outpatient clinic. The physicians' average Vancouver scar scale (VSS) of first physician was 1.26 and second physician was 1.2. Compared with the conventional transconjunctival approach, the extended transconjunctival approach with paracanthal incision had similar complication and scarring rates, as well as a lower scarring rate than the subciliary approach while providing much wider surgical fields.
尽管睑缘下或传统的经结膜入路已被广泛应用,但它常常无法获得可接受的视野或导致瘢痕形成。本研究将伴有外眦旁切口的扩大经结膜入路与其他传统入路在手术视野、手术效果及并发症方面进行了直接比较。这项回顾性图表研究纳入了113例患者(82例男性和31例女性;平均年龄:38.7岁;范围:11 - 87岁),这些患者在2009年11月至2013年9月期间接受了眼眶缩小手术。在扩大经结膜入路中,下外侧眦腱的外部皮肤在距外眦约5毫米的自然皮肤皱褶处进行标记。手术入路基于前隔经结膜分离。进行了约5毫米长的眦旁切口。评估了美学和功能并发症,包括可见瘢痕、眼睑退缩或肥厚性瘢痕的存在;溢泪、复视、眶内血肿、持续性眼球内陷或眼球突出;以及睑内翻/睑外翻的存在。扩大经结膜入路导致手术视野面积显著增加,具有统计学意义(P = 0.002)。并发症发生率与其他手术技术相似。通过门诊拍摄的照片确认了术后瘢痕情况。第一位医生评估的患者温哥华瘢痕量表(VSS)平均分为1.26,第二位医生评估的平均分为1.2。与传统经结膜入路相比,伴有眦旁切口的扩大经结膜入路具有相似的并发症和瘢痕形成率,并且瘢痕形成率低于睑缘下入路,同时提供了更广阔的手术视野。
