1, before the operation to maintain a clear understanding, and full communication with the doctor: cosmetic surgery is different from other surgical procedures, such as emergency surgery – appendicitis acute abdomen, if not emergency surgery, will lead to life-threatening; malignant tumor surgery, not as soon as possible surgery will also threaten life safety. Most cosmetic surgeries can be done or not, but once the surgery is performed, it is basically impossible to restore the original appearance, such as double eyelids, once the cut is made, it is impossible to return to the original single eyelids. The process of seeking beauty is a constant negation of the ego. Studies have found that the beauty seekers themselves pre-operative psychological barriers of varying degrees, the face, physical changes and in the social behavior of a variety of factors to the psychological shadow brought to the beauty seekers, so they want to improve their appearance through cosmetic surgery to adjust their already skewed mentality. In fact, for some of the candidates, cosmetic surgery is not able to solve their problems, but rather make them worse and worse. In addition, many beauty seekers are already beautiful, but they strive for excellence and want to become more beautiful, while sometimes the post-operative period is not as beautiful as the pre-operative period. Any surgery has surgical risks, and no surgery can achieve 100% patient satisfaction, not even 50%, so you must fully communicate with your doctor before surgery. Therefore, patients who cannot accept the risks of surgery and those who have too high expectations of surgery are not recommended to have surgery. For cosmetic surgery, patients have the right to decide, not to do surgery if they can, not to use invasive surgery if they can solve through minimally invasive, not to use radical surgery if they can conservative surgery, and doctors are more to provide advice. 2, fully understand their own appearance, correct evaluation of their own psychological needs: preoperative carefully observe their own appearance in the mirror, or take pictures of their own surgical sites carefully see, etc., especially for the parts intended for surgery, such as eye surgery patients should carefully observe their own eyes, nose surgery patients should carefully observe their own nose. Imagine or simulate whether the eyes or nose after cosmetic surgery is the result you want, or just an impulse that other people look good doing it, so I should do it too. Patients should correctly evaluate their own psychological needs rather than the clouds of people. In addition, many patients actually do not have a clear understanding of their five senses before surgery, for example, they just feel that their nose is low and flat and want to do rhinoplasty, but they do not find that their nose is crooked; for example, they feel that they have single eyelids and want to do double eyelids, but they do not find that their eyebrows are high on one side and low on the other, and their eyes are big on one side and small on the other. After rhinoplasty, you stare at your nose every day and find that your nose is suddenly crooked, but it was crooked before surgery. The surgery alone can only change your single eyelids to double eyelids, but it cannot correct the size of your eyes. Therefore, surgery is not recommended for patients who are not fully aware of their appearance. 3. Maintain a good attitude after surgery and give yourself more time to recover: There is a recovery period after surgery, usually six months to a year. After cosmetic surgery, patients will experience a process of “first becoming ugly, then becoming beautiful”, the swelling will slowly subside, the tissue will slowly repair, and the situation will become better and better. Many patients do not adapt to their new selves after surgery, or feel that something is not done well, and are eager to fix it, so they stare at their surgical parts every day, constantly obsessing and seeking medical help everywhere, causing a lot of psychological pressure. Such as after fat filling, there will be facial swelling and short-lived unevenness, etc. Patients appear anxious and hate to immediately pump out the filled fat again, post-operative recovery is a process, give yourself a little more time. Cosmetic surgery usually takes three months to see the approximate results. Many of the post-operative problems will slowly get better over time, and very few of them need to be repaired. If a repair is needed, you should wait until a year after the surgical site has recovered and operate again. Multiple surgeries in a short period of time should not be performed, as this will cause more trauma to tissues that have not yet been repaired. The recovery time may vary depending on each individual’s surgical procedure, body type, and diet. Therefore, patients who cannot accept a long post-operative recovery period and who want to recover completely after 1-2 weeks of surgery are not recommended to have surgery. 4. Regarding scars, no method can completely remove them: Any invasive cosmetic surgery will produce scars, which are unavoidable and impossible to completely remove. Double eyelid surgery with incision will leave scars, inner eye opening will also leave scars, and body surface swelling (mole) will also leave scars after excision. Plastic and cosmetic surgeons can make scars shrink and reduce inconspicuously, but they are not capable of removing them completely. Therefore, surgery is not recommended for patients who cannot accept that cosmetic surgery will leave scars, or who want to completely remove scars through cosmetic surgery. Eye surgery: swelling is more pronounced within 1 week after surgery, gradually subsides in about 2 weeks, and swelling generally disappears basically completely in 3 months. Incisional blepharoplasty (double eyelid) surgery will initially tighten and have a pulling sensation in the wound, and buried blepharoplasty (double eyelid) surgery will have pressure and tightness pulling sensation and mild pain and discomfort in the upper eyelid after surgery, etc. This is a natural course of disease that slowly recovers. There will be scars after inner eyelid surgery, which become less and less noticeable as time goes on. Prosthetic rhinoplasty: there may be a small amount of bleeding in the nasal wound within 2 days after surgery, and the swelling may cause the nose to appear high in the short term, gradually becoming lower and more natural after the swelling subsides, and the shape will be basically stable and fixed after half a year. Botulinum toxin injection (face slimming / wrinkle removal): the effect starts to appear in 2-4 weeks after injection; the effect is most obvious in about 2-3 months after injection, and is injected again at intervals of 6 months. Breast implant augmentation: prohibit strenuous hand lifting activities, such as lifting heavy objects, back expansion exercises (playing tennis, swimming), etc. for 3 months after breast augmentation. Facial fat filler: swelling is obvious 3-5 days after surgery (swelling into a “pig head”), about 10 days after surgery due to different swelling will cause the phenomenon of unevenness, facial fat filler surgery is completely swollen and basic shaping time is 3-6 months, fat absorption rate is about 50%. Post-operative precautions: 1. Avoid water in the wound for a week after surgery; 2. Take oral or static antibiotics for 3 days to prevent infection; 3. Prohibit smoking and drinking alcohol for 3 weeks before and after surgery; 4. To promote swelling, apply cold compresses for 48 hours after surgery, and warm compresses for 48 hours; 5. Generally remove the stitches for about 1 week after surgery, and extend the removal time for parts with slow healing and high tension; 6.
