Clinical Characteristics and Treatment of Blow-out Fracture Accompanied by Canalicular Laceration

Abstract

Fractures involving the medial wall with a lower canalicular laceration were the most common among concomitant blow-out fractures and canalicular lacerations. The severity of the fracture was most often classified as severe. Computed tomographic scan of the orbit and facial bones for identification of any additional injuries such as orbital wall and facial bone fractures should be performed in patients with canalicular laceration. To avoid disruption of the medial canthal area, repair of the canalicular laceration with silicone tube intubation was performed before reconstruction of the blow-out fracture through transconjunctival and transcaruncular approaches. Finally, the tube was fixed after blow-out fracture surgery, and these surgical orders yielded good surgical outcomes without complications.
