To report a case of conjunctival sac fistula after cosmetic lateral canthoplasty which is rare.
A young women who underwent bilateral canthoplasty appeared with lacrimation of the right eye. We found there was a skin fistula with transparent tears at 2 mm lateral to the right canthus ligament and the liquid containing fluorescein was seen to overflow at the fistula after using fluorescein sodium eye drops. The number 7 lacrimal duct probe was visible under the temporal conjunctiva when exploring the fistula, and the fistula was about 4 mm. The patient was diagnosed with conjunctival sac fistula and fistula excision was performed. The patient did not tear abnormally after observation 3 months later and the incision healed well.
The case report illustrates an uncommon post-lateral canthoplasty complication. We suggested that surgeons who perform this kind of surgery should ask about epiphora and look for conjunctival sac fistula at follow-up assessment.
报告一例美容性外眦成形术后发生的结膜囊瘘，较为罕见。
一位年轻女性接受了双侧外眦成形术，出现右眼流泪。我们发现右侧外眦韧带外侧 2mm 处有一个皮肤瘘，滴入荧光素钠滴眼液后可见含有荧光素的液体从瘘口溢出。探查瘘口时，在颞侧结膜下可见 7 号泪道探针，瘘口约 4mm。患者被诊断为结膜囊瘘，并进行了瘘管切除术。术后 3 个月观察未见异常流泪，切口愈合良好。
本病例报告说明了一种不常见的外眦成形术后并发症。我们建议行此类手术的外科医生应在随访评估时询问患者是否流泪，并寻找结膜囊瘘。
