Abstract

We report a case of congenital lacrimal sac fistula located on the temporal side of the lateral canthus. A systemically healthy 1-year-old girl came to the outpatient clinic with a complaint of tearing on the temporal side of the right lateral canthus since birth. On examination, a small orifice was found in the skin on the temporal side of the lateral canthus. There was no evidence of inflammation or swelling within the opening. Surgeons carried out an operation under general anesthesia. They passed a probe through the lacrimal orifice and advanced it toward the lacrimal sac. Next, they introduced saline to the inferior punctum and found that it drained to the lateral fistula. The lower lid stretched as the dissected fistula was pulled. After the operation, the patient was free of the symptom. This paper is to report a case of congenital lacrimal sac fistula located on the temporal side of the lateral canthus.
