"Map tongue" is also called exfoliative glossitis, pityriasis glossitis, wandering glossitis or spotted glossitis. Because of the erosion of tongue surface, it looks a bit like a map, so it is called "map tongue". In fact, this is the frequent "dressing change" of tongue tissue. Every baby's "map tongue" performance is different, some can see it clearly, and some can't see it at all. A small "map" on the tongue will appear two or three months after the baby is born, which is most common when he is 2-4 years old. When the "map tongue" first appeared, it peeled off in a small area, with no fixed erythema, slight protrusion and clear boundary. The peeling range will gradually expand and spread around. Sometimes it can completely return to normal, but it may also recur. Generally, when peeling is serious, people will feel uncomfortable when eating spicy and other irritating foods, and sometimes they will feel burning. According to experts, the cause of "map tongue" is still certain, which may be related to inflammation, constitution, allergic reaction, zinc deficiency, intestinal parasitic diseases and so on. Therefore, when parents find that their baby has a "map tongue", don't underestimate it. They need to go to the hospital for a doctor's diagnosis and find out the cause carefully. After examination by a doctor, if there are no special circumstances, treatment is generally not needed. Map tongue is a common disease in children, and its incidence is related to mental and neurological factors, physical factors and nutritional factors. At first, the lesion was small, and then it gradually increased. While developing, it was repaired, constantly changing and wandering, often changing positions overnight. Children with map tongues generally have no obvious symptoms. Eating irritating food can cause tongue discomfort, burning, itching, accompanied by loss of appetite, irritability and other manifestations. For children's tongue, you can take the following countermeasures at home. ◆ Pay attention to rest and diet. First of all, we should arrange our lives reasonably to ensure that children have enough sleep time and avoid excessive fatigue. Enrich all kinds of meals in time to ensure adequate nutrition intake. ◆ Eliminate infection focus, avoid stimulating some bacteria in oral cavity, and also induce map tongue. Therefore, it is necessary to carefully check whether the child's oral cavity and buccal mucosa have infected lesions, and treat them in time once found. At the same time, avoid stimulating factors that may induce the disease, such as some antibiotics. ◆ Medicate children with chronic persistent diseases, pay attention to the damage to mucosa, and give oral vitamin B or zinc sulfate preparation. Children with iron deficiency anemia should be supplemented with iron to correct anemia ◆ Symptomatic treatment should be taken to keep the sick children's oral cavity clean and hygienic. Every morning, you can gently brush 1~2 times from the back of your tongue with a soft toothbrush to remove the exfoliated epithelium. At the same time, give weak alkaline drugs to gargle, such as 2% sodium borate or 0.5% sodium bicarbonate solution, which can be dripped with a dropper. Children who are restless and unwilling to eat because of pain can be coated with non-irritating disinfectant, such as chlortetracycline solution.
