Annular intubation with pigtail probe for canalicular lacerations

Pigtail probe as a procedure of choice for canalicular laceration.

Retrospective, consecutive interventional case series of patients with eyelid laceration involving the canaliculus undergoing repair. All patients were subjected to repair with pigtail probe as first choice and only if this was not possible, they were repaired by other method. Outcome was analyzed in terms of cosmetic, functional, and anatomic success.

A total of 35 patients (mean age, 10.88 years) underwent eyelid and canaliculus repair by a single surgeon (RM). In all, 32 (91.42%) canalicular lacerations were repaired by annular intubation using a pigtail probe, while the remaining 3 (8.58%) lacerations in which pigtail probe intubation was not possible, were repaired by an alternative method. Upper canaliculus was involved in 6 (17.14%) and lower canaliculus in 29 (82.86%) eyes. Mean follow-up was 8.2 months (range 3-13 months). Intubation tubes were removed after at least 3 months (range 12-20 weeks). None of the patients had complaints of epiphora. All the patients had good cosmesis, anatomic alignment and functional success as assessed by dye disappearance test in younger children and lacrimal irrigation in older children and adults.

Bicanalicular annular repair with pigtail probe achieved excellent functional and cosmetic results. The loop minimizes the chances of extrusion of the tube, maintains natural anatomic alignment of the cut ends of the canaliculus and thus retains the integrity of the delicate canalicular system. Pigtail probe intubation can be considered as the first choice in canalicular lacerations.
