In recent years, the number of cosmetic surgery cases among plastic surgery outpatients has increased year by year, and many patients have rebuilt their self-confidence through cosmetic surgery, but the success of each case of cosmetic surgery depends not only on the patient’s own conditions, the aesthetics of the surgeon and the meticulousness of the surgical operation, but also on the patient’s own care after the surgery is an important part of the success of the surgery. In the course of daily treatment, I found that individual patients did not listen carefully to the doctor’s post-operative instructions, resulting in some unexpected situations or even surgical failure, leaving lifelong regrets. Therefore, it is necessary to explain here some of the post-operative precautions that patients need to take after cosmetic surgery. The following list is just some of the common post-operative cosmetic surgery needs to pay attention to: 1, after surgery to the removal of stitches before to prohibit smoking and alcohol, prohibit spicy and stimulating food, prohibit seafood, beef and mutton, etc., prohibit large tonic drugs or food: such as ginseng tonic, etc., prohibit smoking and alcohol, especially within 3 days after surgery, smoking is strictly prohibited, otherwise the incision is prone to infection or cracking. A light diet is available, and the daily diet of eggs, chicken, milk, etc. can be consumed normally. 2, the wound should not be wet before the removal of the stitches, after the removal of the stitches cleaning time please follow the doctor’s instructions. Facial surgery should reduce facial and oral activities, such as laughing, chewing hard food. Wound healing local should avoid chronic stimulation such as friction, etc. Oral surgery should be gargled with mouthwash or gargled with other disinfectant solution every day. 3.Follow the doctor’s instructions to take postoperative drugs to prevent infection in a timely manner after surgery, do not apply other drugs on your own. 4, the second day after surgery, you can remove the gauze covering the wound by yourself. After that, apply erythromycin ophthalmic ointment on the wound with a clean cotton swab 3~5 times a day until the stitches are removed at the follow-up. Tip: You must also apply erythromycin eye ointment before leaving home on the morning of stitch removal! 5, 6 days after surgery wound removal, or follow the doctor’s instructions, without the physician’s permission can not be privately to remove the stitches outside the hospital. 6.After eye and nose cosmetic surgery (blepharoplasty, eyebag removal, rhinoplasty, hump nose correction, etc.), apply pressure or cold compresses for 1 to 2 hours to reduce blood oozing and swelling, and rest on a slightly elevated pillow at night. 7.Avoid collision and vigorous rubbing within 1 month after nose and chin cosmetic surgery. 8, post-operative wound swelling, bruising, hardness, itching is a normal surgical reaction, no need to review.
