Abstract：
We evaluated the efficacy and clinical outcomes of bicanalicular-nasal silicone stents for deep canalicular lacerations and their anatomical restoration advantages. This retrospective case series study included patients with deep canalicular lacerations who underwent bicanalicular-nasal silicone stent intubation between January 2010 and June 2021 at a Chinese tertiary hospital and two primary hospitals. Intra- and post-operative complications were recorded. Anatomical, functional, and cosmetic outcomes were evaluated as anatomical restoration assessments at the last follow-up. We defined anatomical success as a free passage with no reflux during irrigation. Functional success was evaluated using the Munk epiphora scale and fluorescein dye disappearance test. Cosmetic outcomes were evaluated by examining the eyelid, lacrimal punctum, and medial canthus for any structural abnormalities and recorded objectively using a grading scale. We evaluated 92 eyes of 92 patients (63 men and 29 women); the mean distance from the lateral lacerated end to the punctum was 7.74 mm (range 7-10 mm). Bicanalicular-nasal silicone stents were successfully used in all 92 eyes with no severe intra- or post-operative complications noted. The stent placement duration ranged from 12 to 16 weeks (mean, 13.18 weeks). The follow-up period after stent removal ranged from 3 to 12 months (mean, 6.04 months). The anatomical and functional restoration success rates were 96.74% (89/92) and 100% (92/92), respectively. Satisfactory eyelid position realignment was achieved in all patients. Bicanalicular-nasal silicone stent placement sufficiently relieved orbicularis muscle tension during deep canalicular laceration repair, providing good functional results and excellent cosmetic realignment and anatomical restoration of the eyelid.
摘要：
我们评估了双管-鼻硅胶支架治疗深小管撕裂的疗效和临床效果及其解剖修复优势。这项回顾性病例系列研究包括2010年1月至2021年6月在中国一家三级医院和两家基层医院接受双管-鼻硅胶支架插管的深小管撕裂患者。记录术中和术后并发症。解剖学,功能，和美容结果在最后一次随访时评估为解剖恢复评估。我们将解剖学成功定义为在冲洗过程中没有反流的自由通道。使用Munk顿唇量表和荧光素染料消失测试评估功能成功。通过检查眼睑来评估美容结果，泪点,和内侧眼角的任何结构异常，并使用分级量表客观记录。我们评估了92例患者的92只眼（63例男性和29例女性）；从外侧撕裂端到泪点的平均距离为7.74mm（范围为7-10mm）。双管鼻硅胶支架成功用于所有92只眼，未发现严重的术中或术后并发症。支架放置时间为12~16周(平均13.18周）。支架取出后随访3~12个月(平均6.04个月）。解剖和功能恢复成功率分别为96.74%(89/92)和100%(92/92),分别。所有患者均获得了满意的眼睑位置重新对齐。双管-鼻硅胶支架放置可充分缓解深泪小管裂伤修复期间的眼轮匝肌张力,提供良好的功能效果和出色的美容重新排列和眼睑的解剖恢复。
