To report the epidemiological data, clinical profile, management, and outcomes of canalicular lacerations in the pediatric age group in a tertiary eye care hospital in Saudi Arabia.
This retrospective study evaluated pediatric patients who underwent canalicular laceration repair in the last 15 years at King Khalid Eye Specialist Hospital (KKESH), Saudi Arabia. Demographics, causes of injury, type of trauma, surgical approach, and outcomes were analyzed. The success of repair was defined as the absence of epiphora after canaliculus repair with negative dye disappearance test (DDT). Success within subgroups was compared. < 0.05 was considered statistically significant.
The study sample was comprised of 43 patients, with a median age of 6.35 years (range, 1.77-17.96 years). Most of the patients were males (69.8%). Sharp objects were the most common cause of canalicular laceration (46.5%), being 9 (20.9 %) caused by a metallic clothing hanger. Lower canaliculus was involved in 65.1%, upper canaliculus in 32.6%, and both canaliculi in 2.3% of patients. Canaliculus repair was performed with a bicanalicular stent in 58.1 % and monocanalicular stent in 41.9 % of patients.The success rate and risk of complications using bicanalicular or monocanalicular stent did not differ ( = 0.065). Functional success was achieved in 87.5% of patients.
Canalicular laceration is common in male children, mainly affecting the lower canaliculus. There was no difference in success rate between monocanalicular and bicanalicular stent. As canalicular laceration could be related to social determinants, the main causes should be highlighted in community health education initiatives.
报告沙特阿拉伯一家三级眼科护理医院儿科年龄组泪小管撕裂伤的流行病学数据、临床特征、治疗及预后。
这项回顾性研究评估了过去15年在沙特阿拉伯国王哈立德眼科专科医院（KKESH）接受泪小管撕裂伤修复术的儿科患者。分析了人口统计学、受伤原因、创伤类型、手术方式及预后。修复成功定义为泪小管修复后无溢泪且染料消失试验（DDT）为阴性。比较亚组内的成功率。P<0.05被认为具有统计学意义。
研究样本包括43例患者，中位年龄为6.35岁（范围1.77 - 17.96岁）。大多数患者为男性（69.8%）。锐器是泪小管撕裂伤最常见的原因（46.5%），其中9例（20.9%）由金属晾衣架导致。65.1%的患者下泪小管受累，32.6%的患者上泪小管受累，2.3%的患者上下泪小管均受累。58.1%的患者采用双泪小管支架进行泪小管修复，41.9%的患者采用单泪小管支架。使用双泪小管或单泪小管支架的成功率和并发症风险无差异（P = 0.065）。87.5%的患者获得功能成功。
泪小管撕裂伤在男童中常见，主要影响下泪小管。单泪小管支架和双泪小管支架的成功率无差异。由于泪小管撕裂伤可能与社会决定因素有关，社区健康教育活动应突出主要原因。
