In fact, the canthus is a vertical fold of skin in front of the inner corner of the eye, mostly seen in Oriental peoples, the existence of the canthus will be the inner corner of the eye and the tear mound partially or completely covered, the existence of the canthus makes the spacing between the two sides of the inner canthus widen, appearing flat nose, narrowing the horizontal diameter of the eye, so that the vivid rhyme of the eyes also looks dull. The redundant skin not only makes the eyes lose their beauty; but also blocks part of the line of sight and hinders the function of seeing things, so let’s follow the experts of the Plastic Surgery Center of Zhejiang Provincial People’s Hospital to learn more about the inner canthus correction surgery. What is medial canthus: “Medial canthus” is a half-moon skin fold that covers the vertical aspect of the medial canthus, often formed by the continuation of the upper lid to the medial canthus, all bilateral. The canthus is closely related to ethnic differences. It is most commonly found in the Mongolian population in Central, North, and East Asia, and is therefore also known as the “Mongolian fold. The medial canthus is a vertical skin fold that naturally creates skin tension in the vertical direction, whereas the fold formed by the eyelid is horizontal, and when the eyelid furrow is opened, it is also a vertical pull. The canthus can be divided into two categories: primary and secondary. Secondary canthus is mostly caused by traumatic injuries that result in thick scarring of the medial canthus; webbed scarring caused by infection of the medial canthus can cause significant widening of the medial canthus and shortening of the lid fissure, often combined with adhesions of the lid bulb and lid margin and tear duct injury. Primary canthus can be divided into upper, inner, and lower canthus according to its location. The skin folds can be divided according to the starting site of the bifurcation into: brow canthus, preorbital canthus, lid canthus, and inverted canthus. In primary canthus, if it is accompanied by ptosis, narrowing of the lid fissure and a significant widening of the medial canthus, it is called eyelid syndrome. The canthus correction procedure: A minimally invasive incision is made within the eyelid line and operated subcutaneously. No direct skin incision is made to avoid local scar formation. Water, no painful stitch removal, and very natural and smooth results after inner canthus correction.
