There are two types of cases here, one is a break in the sensory nerve and the other is a break in the motor nerve. Our skin normally feels alternating hot and cold and painful stimulation relying on sensory nerves, which are present from deep to superficial surfaces, just like tree branches. And facelift surgery will separate the face, and all the sensory nerves will be stripped off in the passing section, and only when they are stripped off, the face can be stripped off, which is the characteristic of sensory nerves. The motor nerve, which governs the movement of the face, is also the most worried area in the surgery. The motor nerve is generally divided into five branches, which govern the movements of the temporal area, eyebrows, cheekbones, eyelids, lips, corners of the mouth, neck, and eyes, and it exists in the SAMS fascial layer, so it is important to avoid damage to these nerves during the stripping surgery. For the surgeon, he or she must try to avoid damage to the motor nerve during the operation and carefully peel it off, but for some nerve variants, or nerves that are more closely connected to the skin layer, there is a possibility of damage. Motor nerves and tissues are very similar in color and also very small, some are even thinner than the clothes of the usual sutures, so during the stripping process, most doctors use blunt stripping, so disconnected injuries rarely occur, but with pulling injuries, they can usually be recovered, but it takes a little longer, usually about a year long process. There are risks associated with surgery, and with cosmetic surgery, even more caution is needed. I usually speak to candidates that cosmetic surgery is not a necessary procedure, and if the risks are not acceptable, my advice is not to do it, and that is not an empty phrase! Before surgery, you must seriously consider the risks of surgery, whether you can afford it if it fails, and have some psychological intervention before surgery, so that you can’t just feel good about the results and ignore the risks.
