Eye opening generally refers to opening the inner corner of the eye, with the aim of solving the problem of covering the inner canthus in order to achieve the effect of making the inner canthus visible. There are many clinical methods, such as the incision method, flap method, and one-line method, all of which can achieve the effect of opening the inner canthus, as follows: 1. The flap method, with a Z-shaped reshaping, cuts the skin along the longitudinal axis of the inner canthus to form two small triangular flaps, and then performs misaligned suturing, which can effectively solve the inner canthus, but the flap method, due to problems such as excessive tension and misalignment of the skin lines, can easily form a local scar in the inner corner of the eye, resulting in the inner corner of the eye The eyelid line is displaced; 2. The incision method, which directly cuts the inner canthus horizontally, fixes the end on the nasal tendon membrane, and performs simple trimming on the top and bottom respectively to achieve a perfect fit with the heavy eyelid, and can loosen the inner canthal ligament if necessary; 3. Other methods, such as the one-line method, can be adopted.
