Medial Canthal Tendon Avulsion
Damage to the eyelid commonly occurs secondary to blunt trauma, animal (dog) bites, motor vehicle collisions, falls, or assault with horizontal or lateral traction to the eyelid leading to shearing of the lid generally medially. This is especially common in naso-orbitoethmoidal fractures. Additionally, iatrogenic injuries can occur during oculoplastic or otolaryngology surgery, such as during dacryocystorhinostomy or after surgical resection of periocular tumors. These injuries can cause avulsion at the posterior limb of the medial canthal tendon, which is relatively weak against lateral tractional force.
