Abstract:
The authors report the diagnosis and treatment of a patient who developed a conjunctival fistula after undergoing cosmetic lateral canthoplasty. A 34-year-old female patient continued to shed tears in the canthus skin of the left eye for 3 years after undergoing cosmetic lateral canthoplasty. She underwent preoperative fluorescein sodium staining and tear duct probing, which led to a diagnosis of conjunctival fistula. Methylene blue was used as a diagnostic marker and the tear duct probe was positioned for conjunctival fistula resection intraoperatively. Postoperative recovery was good. The causes of tearing of the canthal skin after cosmetic canthal surgery are divided into the following 3 types: lacrimal gland fistula, lacrimal ductal fistula, and conjunctival fistula. The authors further developed its preoperative identification method and treatment.
