The white lip area, due to movements such as talking and chewing, is a location on the face that is prone to significant scarring. The incision is easily widened in the early stages due to the presence of tension, and small red or lavender slightly concave marks can be observed with the naked eye. Good postoperative care is especially important. I have summarized a set of simple and easy ways to control scarring and have achieved good results. I share it with you to improve it together. Treatment of suture scar: Many incisions of cleft lip are performed with interrupted sutures, usually mostly 6-0 thick and thin sutures, and some use 5-0 silk or absorbable sutures. In the early stage, we must first prevent the cutting injury of sutures, which are most likely to produce cutting line marks when the tissue is swollen. 1-3 days after surgery, which is the most swollen period of the lip, diet is fluid, spoon feeding, avoiding talking and expression movement. The dressing must be applied with moderate pressure and iced. Pressurized ice packs are good for eliminating swelling. When removing the sutures 1. remove clean sutures to avoid residue. 2. avoid bleeding from the eye of the line and draw the sutures slowly. 3. avoid oral and lip activities throughout the removal of the sutures, inform the patient or the child in advance under basic anesthesia. 4. fix the incision Immediately after removal of the sutures use medical glue for incision fixation to reduce tension on both sides. 5. the absorbable sutures in the white lip area should also be removed in 7 days, do not wait to fall off on your own. Post-operative scar care: The purpose is to prevent the incision from widening, and we know that as long as the incision does not widen, no proliferative scar will be produced. The fixation of medical glue is particularly important and is equivalent to re-suturing. However, with the recovery of skin function, it is easy for the glue to fall off in 2-3 days later. Each time you replace the medical glue to follow the incision to remove the glue skin, saline alcohol clean up and continue glue fixation, fixed 2-3 months when the effect is very obvious. If there is no obvious widening please continue to use until six months or skin allergy termination. If the widening of the self-conscious without hyperplasia or economic conditions do not allow the use of silicone gel type such as Beyshu trace, Barker, etc.. The general treatment cycle is six months. During this period, diet should avoid spicy and stimulating food, avoid greasy food, avoid perioral movement and limit expression movement. Matters needing attention: avoid using glue if the incision is infected, oozing and under excessive tension. Dressings should be used to shield the eyes from entry when glue is applied. For infants and children who cannot cooperate with the child: also 2-3 times glue fixation, and then in the use of silicone gel products. About massage: 2 fingers placed on both sides of the incision, fix the incision, 2 fingers should not be shifted, clockwise movement can reduce the upward movement of the lip crest and soften the scar. If your scar is already hyperplastic and red and tough: fractional laser, plasma, microneedling can be performed. If your scar is slightly depressed: fractional laser, plasma, or microneedling can be performed. If your scar is white and reflective: Fractional laser, plasma, or microneedling can be performed. We believe that if you follow the above mentioned procedures strictly, you will achieve good results.
