I. Can there be no scars after surgery? No! Scars are a normal and inevitable physiological response to the natural healing process of biological wounds or traumas, and an inevitable result of the trauma healing process. If there is a wound, there is a scar! Second, why do patients always worry about scars before surgery? This is because the nature of scars is a kind of tissue that does not have normal skin tissue structure and physiological function. Scars not only destroy the beauty of the body surface, but also hinder the physiological functions of the relevant tissues or organs, produce uncomfortable symptoms such as itching and pain, and even lead to organ deformity. Third, post-operative scars can’t be avoided, what should I do? Prevention is better than cure! There are a series of clinical measures that can minimize the degree of scar production and thus reduce the harm of scars! Plastic surgery attaches great importance to the design of skin incisions. Incisions are placed in non-exposed locations whenever possible, for example, in the nasal cavity for rhinoplasty. Incisions are placed in hidden skin grooves whenever possible, such as in the crease of the eyelids for double eyelid surgery. The incision direction should be the same as the skin texture as far as possible, such as the excision of moles in different parts of the face, the incision direction should be the same as the skin texture. Plastic surgery attaches great importance to the suturing technique of skin incision. The wound must be thoroughly hemostatic before suturing, repeatedly rinsed until clean, and no foreign body left behind. Wound suturing is performed with adequate subcutaneous tension reduction and as much tension-free suturing as possible. Low-damage sutures are used for wound closure, and absorbable sutures are used as much as possible to avoid wound irritation. Plastic surgery attaches great importance to the postoperative care of skin incisions. Wound exudate is removed in time to keep the wound dry and clean. If the sutures are non-absorbable sutures, they should be removed completely in time. Topical scar growth inhibiting drugs should be applied early after wound healing. 4. What should I do if scar growth has already appeared? Common methods: laser treatment; drug injection treatment; radiation treatment; surgical revision, etc. Patients with scars will have different degrees of improvement after comprehensive standardized treatment.
