The best way to recover from a cleft lip is to avoid licking, which may lead to aggravation of the cleft in the mouth and lips. At the same time, topical application of recombinant human epidermal growth factor gel can be given topically to promote rapid healing of the skin. It is best not to use toothpaste containing fluoride to avoid irritating the skin mucosa of the mouth and lips, and not to make food soup stick to the mucosa of the mouth and lips to avoid irritation. You can use a spoon to eat food, and pay attention to balanced nutrition and no partial diet, so as not to lead to the lack of trace elements or vitamins, thus making the mouth and lips prone to cleft. After the mouth and lip cleft is recovered, if the skin mucous membrane of the mouth and lip area is dry, you can give vitamin E pellets and apply them to the mouth and lip area after tying, and you can also supplement vitamin B complex and vitamin E appropriately in general.
