After dermatologic surgery, certain treatments are required to smoothly pass the recovery period and obtain the desired results. 2.Postoperative pain: it often occurs after surgery, and the pain at the wound can appear after the anesthetic effect disappears, and it gradually decreases 1-2 days after surgery. Postoperative pain is generally tolerable, and pain can be relieved by appropriate application of painkillers or sedatives. If the pain is severe or progressively worsens, prompt medical attention is required. 3. Prevent infection: postoperative antibiotics can be applied for 1-3 days as appropriate, and cephalosporin antibiotics can be chosen orally for those who are not allergic to cephalosporins, and roxithromycin can be chosen orally for those who are allergic. 4. Post-operative medication change: start medication change on the second day after surgery, preferably every day, or you can decide the number of medication changes according to the doctor’s arrangement. Try to go to regular hospitals or outpatient clinics for medication changes. If you change the medicine by yourself, you need to purchase 75% alcohol, cotton swabs, gauze, etc. in a formal way. First, use tweezers to hold one end of the excipient to uncover the excipient, and when the excipient is closely adhered to the wound, use saline to soak it and then uncover it. Then use alcohol to start wiping the wound 2-3 times to try to remove the blood crust on the surface, and when the blood crust is difficult to remove, use alcohol or saline to soak wet for 3-5 minutes before removing. After disinfection, apply a thin layer of anti-infection ointment on the wound surface, and then use sterile gauze or band-aid to fix it. If the wound is found to be red, swollen, pus-flowing and in severe pain, prompt medical attention is required. 5. For patients with high nasal, perinasal and oil secretion, it is not necessary to continue to use gauze or band-aid to dress the wound after 3 days postoperatively to expose the wound to avoid local accumulation of oil causing wound infection. 6. Post-operative suture removal: According to the surgeon’s request to remove the front line at the regular hospital or clinic at the specified time. Internal sutures can generally be absorbed in 3-6 months, and some cannot be absorbed with possible discharge from the wound periphery. 7. One week after stitch removal, you can start to use anti-scar medication, and it is recommended to use it continuously for 3 months.
