Hello, the resident expert said: There are several common traditional methods to open the corner of the eye: (1)V-type or L-type skin excision method: the method is simple, but some skin needs to be removed. Suitable for patients with slack eye skin. (2) Transverse canthotomy: it is simple to operate and is mostly used by doctors. But to cut off the insufficient skin, the incision is neat and V-shaped, which is easy to shrink. (3)Z-shaped canthus opening method: simple operation. But the release is not thorough enough, suitable for a little epicanthus. (4)Y-V method of pushing away the corner of eyes: relatively simple and effective. I hope it helps you! !
