| The lateral and medial canthal ligaments hold the lid to the surface of the anterior eye. |
| However, forward movement is limited by the medial and lateral canthal tendons that attach the eyelids to the bony orbital rim. |
| Initially, cantholysis should be performed, including both a lateral canthotomy and canthal tendon disinsertion. |
| Medially, the canthal ligament splits and surrounds the lacrimal apparatus. |
| At this point, a medial canthal incision was made, and vessels extending over the nasal bridge were clipped, as was the anterior ethmoidal artery. |
| The patient underwent a right lateral rhinotomy with wide local excision and primary closure of the right medial canthal soft tissues. |
