Pathogenesis of Canalicular Lacerations

Abstract

Direct, indirect, or diffuse forces may injure canaliculi but direct penetrating injuries were more common than avulsive injuries. More serious injuries (orbital fractures, globe rupture, other body injuries, and head trauma) were more commonly seen when diffuse trauma was involved.

Evaluation of the anatomical and functional outcomes in patients undergoing repair of traumatic canalicular laceration

“…Jordan et al [5] found inferior laceration in 50%, superior laceration in 23%, and bicanalicular laceration in 4% of cases. In the present study, percentage of inferior canalicular injury cases was 83% (n=34), whereas superior canaliculus was site of trauma in 17% (n=7).…”

“…Jordan et al reported that direct injury was responsible for laceration in more than half (54%) of cases. [5] In 25-case review conducted by Wulc et al, they reported 84% avulsive injury and 16% direct injury. [6] In the present study, too, avulsive injury was observed in majority of the patients; however, it seems that this classification is not used in many series regarding canalicular laceration.…”

“…[7,8] In addition, pigtail probe may be used to detect distal end of cut. [5] Although high surgical success rates have been reported with pigtail probe and annular intubation, this technique has disadvantages of creating false passage and causing damage to the unaffected canaliculus. [16] Surgeon using this method must be experienced and avoid iatrogenic damage to robust nasolacrimal tissues.…”

“…[5,12,13,16,[23][24][25][26][27][28][29][30][31][32][33] Bicanalicular intubation has rate ranging from 30% to 100%. [5,13,15,26,31] Jordan et al [5] reported success rate of 94% in large series, which included 222 bicanalicular intubations. Success rate in binasal intubation series of 24 cases reported by Hawes et al was 95%.…”

Kliniğimize Başvuran Lakrimal Kanalikül Travmalı Olguların Değerlendirilmesi

“…Tek kanalikül yaralanması daha sık görülmekte ve alt kanalikül, üst kanaliküle göre daha sık yaralanmaktadır. [5][6][7] Lakrimal boşaltım sistemi künt veya kesici travmalar sonucunda yaralanabilir. Literatürde indirekt travmaların direkt kesici travmalardan daha sık olduğu ifade edilmektedir.…”
