目的：分析先天性泪腺皮肤瘘伴异位泪腺的临床表现，总结其治疗方案。方法：采用病例研究与文献回顾方法，记录1例确诊为先天性泪腺皮肤瘘伴异位泪腺患儿的外观照片、泪道探查冲洗情况、泪腺瘘管数字减影检查、泪腺瘘管CT造影检查等结果。予患者行泪腺瘘管下段及异位泪腺切除+泪腺瘘管上段转位结膜囊吻合代泪腺导管术，术中切除的病变组织行病理检查，术后随访。以“泪腺瘘”、“异位泪腺”为检索词，在 PubMed、CNKI 数据库中进行文献检索，检索到相关文献共 25 篇。结果：患儿为男性，5岁，眼科检查于左眼上睑中外1/3处见直径约1 mm瘘口，瘘口皮肤凹陷并有簇状毛发生长，有透明液体从瘘口阵发性流出。泪器检查示左上睑皮肤瘘管开口朝外上方，瘘管探查从瘘口进针，瘘管先是内下方走行再向外下走行，在距皮面3.5 mm处有一软性抵抗，加压不能突破，冲洗液原路反流，无脓液或血性液体反流。左眼泪腺瘘管数字减影检查示左眼泪腺瘘管造影剂存留，瘘管深部存在扇形腔隙。泪腺瘘管CT造影结果显示左眼外侧泪腺高密度影。术后随访6个月，患儿左眼上睑切口愈合好，未见瘘管复发，转位的泪腺瘘管成功将泪液引流入上穹隆结膜囊内。结论：先天性泪腺瘘同时合并先天性泪腺异位和毛发异位者临床上罕见，术前详细检查和精确诊断对指导治疗很有帮助；在明确主泪腺是正常的情况下，完整切除异位的泪腺组织，并行泪腺瘘管转位吻合于上穹隆结膜囊代泪腺导管术，是一种较好的治疗选择。

Objective: To demonstrate the clinical characteristics and surgical effects of congenital lacrimal gland cutaneous fistula with ectopic lacrimal gland. Methods: Observational case study and literature review. The results of appearance photographs, lacrimal duct probing and irrigation, digital subtraction imaging of the lacrimal fistula, and CT scanning of lacrimal fistula in a patient diagnosed with lacrimal gland cutaneous fistula with ectopic lacrimal gland were recorded. The surgical treatment for the patient was explored. The surgical strategy entailed resecting the lower segment of the lacrimal gland fistula and ectopic lacrimal gland, combined with transposing the upper segment of lacrimal gland fistula for conjunctival sac anastomosis, instead of using lacrimal gland catheter. Pathological examination and postoperative follow-up were conducted. Results: Ophthalmic examination revealed a fistula with a diameter of approximatedly 1 mm in medial-temporal 1/3 of the upper eyelid of the left eye. The skin surrounding the fistula was sunken and covered with tufts of hair. There was a paroxysmal discharge of clear fluid from the fistula. Lacrimal examination showed that the opening of the fistula on the skin of the left upper eyelid was directed outward and upward. Fistula exploration was conducted through the opening. The fistula tract initially coursed medially and caudally, then laterally and caudally. At a depth of 3.5mm from the dermal surface, a soft resistance was encountered that could not be overcome with forced pressure. The irrigation fluid refluxed along its original pathway, with no pus or bloody fluid regurgination. Digital subtraction imaging of the lacrimal fistula in the left eye demonstrated that contrast media remained and formed fanshaped spaces in the depth of the fistula. CT results of lacrimal fistula revealed a high density of lacrimal gland in left eye. During outpatient follow-up six months after surgery, the incision on the left upper eyelid was observed to have healed well, with no recurrence of the fistula The transposed lacrimal fistula successfully diverted tears into the conjunctival sac of the upper fornix. Conclusions: Congenital lacrimal gland cutaneous fistula combined with congenital ectopic lacrimal gland and ectopic hair is rare in clinical practice. Detailed preoperative examination and accurate diagnosis are extremely beneficial for guiding treatment. When the main lacrimal gland is normal, a better treatment choice involves completely removing the ectopic lacrimal gland tissue and transferring the lacrimal gland fistula to the conjunctival sac of the upper fornix to replace the lacrimal gland catheter.
