“…The medial canthus is a complex structure that consists of an anterior and posterior reflection of the medial canthal tendon which envelops the lacrimal sac. 18,20 Literature in the fields of plastic and reconstructive surgery has provided more detailed descriptions of the arterial distribution to prevent complications. 15 The branches of the ophthalmic artery -dorsal nasal artery, supratrochlear artery, and the terminal branch of the angular artery -are responsible for the nutrition of the inner canthus region.…”

The medial canthus represents a fixed-point fulcrum that is necessary for eyelid function. The aim of the study was to investigate the arterial distribution of the inner canthus. The origin, calibration, and branches of the inner canthus arteries and their topographical relations were examined by dissecting 19 cadavers, injecting red latex to their corresponding 38 nasal sections before the dissection. The distance from the dorsal nasal artery to the inner canthus was found to be 7.2 +/- 0.3 mm. In this study, the average diameter of the dorsal nasal artery was 0.74 mm on the right side and 0.88 mm on the left. Concerning the course of dorsal nasal artery on the lateral side of the nose, 4 types were observed. In most of the examples (44.7%), dorsal nasal artery anastomosed with angular artery via thick branch and gave off supplying branches to the medial canthus and to the lateral side of the nose. Dorsal nasal artery is a vessel of satisfactory size and is potentially a good vascular source for a thin free flap. It may be an ideal flap to reconstruct the eyelid defect for texture and color similarity of the inner canthus skin. A better understanding of the inner canthus vascularity should allow modification of reconstructive techniques and reduce postoperative complications.
