What is the relationship between the medial and lateral canthus?

The lateral canthus is generally positioned superior to the medial canthus by approximately 4mm. This anatomical relationship is important to consider during facial evaluations, reconstructive procedures, and aesthetic surgeries. Understanding the positional differences between these two landmarks assists in achieving balance and symmetry in facial aesthetics. The lateral canthus being higher than the medial canthus is consistent with typical human anatomy and contributes to the natural appearance of the eye region.

This spatial relationship can also play a crucial role in surgical planning, particularly in procedures involving the eyelids or the periocular area, where precise alignment is necessary for both functional and cosmetic outcomes. Proper awareness of the positioning of the canthi can help avoid complications and ensure optimal results in surgical interventions.
