Eyelid and tear duct lacerations
Eyelid lacerations may occur following blunt or penetrating injuries (aggravated assault, sports-related, falls, motor vehicle accidents, bites, and scratches). When lacerations do not involve the eyelid margin, suture repair of the skin and occasionally the underlying orbicularis muscle may be all that is indicated. When the eyelid margin is involved, meticulous realignment of the marginal structures is necessary. Trauma to the medial (inside corner) or lateral (outside corner) eyelid may occur if signficant horizontal traction (dog bites) occurred during the injury.
Canthal repair requires specialized reconstructive techniques. Medical canthal injuries frequently are associated with canalicular (tear duct) lacerations. Canalicular repair with lacrimal stent placement may be indicated to minimize the risk of canalicular scarring and tearing following injuries to the medial aspect of the upper or lower eyelid(s). Lacerations of the eyebrow, cheek, lip, and other areas of the face may also require repair following trauma.
