This report is to explore the long-term outcomes of surgical repair of bicanalicular lacerations in Chinese preschool patients. In this report, 12 patients with bicanalicular lacerations were studied between September 2010 and September 2015. The distance from the punctum to the distal canalicular lacerated end was recorded before surgery to classify different types of trauma. All patients underwent surgical repair of the lacerated canaliculi by 1 surgeon within 48 hours after the trauma occurred. After treatment, the lesions were divided into 3 types according to the distance from the punctum to the distal lacerated canalicular end as follows: lateral, medial, and the central. Based on this classification, each lacerated canaliculus was successfully repaired. Nearly half of the lesions (46%) were lateral, 42% were central, and 12% were medial. The average time for locating the proximal lacerated end of the canaliculus was 3.33 ± 1.52 minutes (range, 1.0–7.0 minutes). The follow-up time ranged from 6.0 months to 4.5 year (median, 25 months). Our study showed that 96% (23) of the canaliculi were completely patent. One lateral lesion presented with residual outdoor epiphora in cold weather secondary to left lower canalicular stenosis. All 12 patients had excellent cosmetic results. Our study displayed a surgical management based on the 3 types of lesions helped to find the proximal lacerated end of the canaliculus, and provided excellent long-term outcomes of drainage function.
