Management outcomes of canalicular laceration in children

Pediatric Canalicular Lacerations: Epidemiology and Surgical Outcomes

BACKGROUND

The aim of this study was to report the epidemiology and surgical outcomes of canalicular lacerations in the pediatric age group.

METHODS

All pediatric patients who underwent repair of canalicular lacerations of any cause were included in this study. Age, sex, mechanism of trauma, and type of stent used were recorded.

RESULTS

The study group consisted of 47 patients with a median age of 6.4 years (22 mo-17 y). Thirty of the patients were male (63.8%). The lower canaliculus was affected in 76.6% (n=36), the upper canaliculus in 40.4% (n=19), and both canaliculi in 17% (n=8). The most common cause of canalicular laceration was sharp objects (n=33, 70.2%).

CONCLUSION

Canalicular laceration most commonly affects boys and especially involves the lower canaliculus. There was no difference in functional success between monocanalicular and bicanalicular stents. Prevention of canalicular lacerations should be the main focus.

Pediatric Eyelid and Canalicular Lacerations: Epidemiology and Outcomes

PURPOSE

To characterize the epidemiology of eyelid lacerations, identify risk factors for canalicular involvement, and describe postoperative complications following laceration repair.

METHODS

All patients undergoing eyelid laceration repair at a tertiary care, level I trauma center children's hospital from November 2010 to April 2021 were identified by a Current Procedural Terminology code search. Patient characteristics, surgical characteristics, and surgical outcomes were collected via chart review. Univariate analysis and multivariate logistic regression were performed to identify risk factors for canalicular involvement and postoperative complication.

RESULTS

A total of 165 patients were identified, of whom 136 had at least 1 week of follow-up and were further assessed for postoperative complications. The most common mechanisms of injury were dog bites (62, 38%), falls (33, 20%), and being struck by an object (22, 13%). Eyelid margin involvement was present in 108 patients (65%) and canalicular involvement in 77 patients (47%). Risk factors for canalicular involvement were hook-related injury, eyelid margin involvement, and lower eyelid injury. Thirty-three patients (24%) had postoperative complications, most commonly ptosis (7, 5%), premature stent loss (7, 5%), and eyelid margin notching (6, 4%). There was no association between postoperative complication and antibiotic use, delayed repair, or wound class.

CONCLUSIONS

Hook-related injury, eyelid margin involvement, and lower eyelid injury are risk factors for canalicular involvement. Postoperative complications of eyelid lacerations are generally minor and are not associated with perioperative factors. Close postoperative follow-up is needed to monitor for complication development. [J Pediatr Ophthalmol Strabismus. 2023;60(1):33-38.].
