title: Supernumerary lacrimal canaliculi.
abstract: Supernumerary extopic canaliculi in a 12-year-old white male patient are presented. Their external openings (puncti) were located on the lateral surface of the nose, 1 cm from the inner canthus, and were reaching the lacrimal sac directly. The anomaly was surgically corrected and 2 years after the operation the patient is free of symptoms.
