Pseudohypertelorism and its implications in the treatment of facial fractures.

The traumatic displacement of the medial canthal ligament results in telecanthus which produces the clinical appearance of pseudohypertelorism. Early recognition of this injury is imperative so that repair is carried out in the acute stage. Because of close anatomical relationships medial canthal injuries are associated with disruptions of the lacrimal system which must be recognized and repaired at the same time.
