Abstract Background To report a case of conjunctival sac fistula after cosmetic lateral canthoplasty which is rare. Case presentation 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. Conclusions 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.
