: To evaluate outcomes of primary eyelid and canalicular laceration repair using a self-retaining bicanalicular hydrophilic nasolacrimal stent.: This study is a retrospective review of seven patients with canalicular laceration primarily repaired with a self-retaining bicanalicular nasolacrimal stent within 72 hours of initial injury. After lacrimal intubation, repair was performed by reapproximation of the lacerated tissues. Data collection included ophthalmic examination, mechanism of injury, involvement of upper/lower/common canaliculi, symptoms of epiphora, operative time, stent extrusion and canalicular irrigation.: Seven patients with monocanalicular laceration were repaired using the self-retaining bicanalicular nasolacrimal stent. The stent was left in place an average of 5 months. The average operative time was 29.3 minutes. None of the stents extruded prior to removal. After 5 months, the stent was removed successfully without difficulty. All patients reported subjective improvement in epiphora, with complete resolution of symptoms. Anatomic success was confirmed with irrigation in all cases. There were no complications associated with usage of the self-retaining bicanalicular nasolacrimal stent.: Primary repair of canalicular lacerations can be successfully performed with a self-retaining bicanalicular nasolacrimal stent. This stent has several advantages, including potentially faster operative times, no need for intranasal fixation or retrieval, easier intubation in the lacrimal system, and improved anatomic reapproximation of lacerated tissues.
: 采用自维持双腔亲水型鼻泪管支架治疗原发性眼睑和泪小管裂伤的效果评估。: 本研究回顾性分析了 7 例在初次受伤后 72 小时内通过自维持双腔鼻泪管支架修复的泪小管裂伤患者。泪道插管后,通过重新接近撕裂组织进行修复。收集的数据包括眼科检查、损伤机制、上/下/总泪小管受累情况、溢泪症状、手术时间、支架脱出和泪道冲洗情况。: 7 例单泪小管裂伤患者采用自维持双腔鼻泪管支架修复。支架平均留置 5 个月。平均手术时间为 29.3 分钟。在取出前,没有支架脱出。5 个月后,支架成功取出,无困难。所有患者均报告溢泪症状主观改善,症状完全缓解。所有病例均通过冲洗确认解剖学成功。使用自维持双腔鼻泪管支架无相关并发症。: 采用自维持双腔鼻泪管支架可成功修复泪小管裂伤。这种支架有几个优点,包括可能缩短手术时间、无需鼻腔内固定或取出、更容易在泪道系统中插管,以及改善撕裂组织的解剖复位。
