Silicone Intubation of Traumatic Canalicular Lacerations

Abstract

To assist in the repair of canalicular injuries, identification of the medial aspect of the canalicular laceration can easily be accomplished by retrograde probing and intubation of the medial canalicular remnant. A dacryocystotomy along the medial side of the nasolacrimal sac will allow direct visualization of the internal nasolacrimal sac anatomy and common internal punctum of the common canalicular system. A retrograde passage of a modified Quickert probe can then be accomplished through the dacryocystotomy incision into the common internal punctum and present in the traumatic wound, identifying the medial aspect of the canalicular laceration.
