Suggestion: We must pay attention to the sequela of silicone pad chin. You mentioned the problem of sequela of silicone pad chin, and I will answer it for you as follows. Hello, it is worth parents' attention that some babies' salivation is pathological, indicating that the baby has some diseases. If the child drools more, accompanied by oral ulcers and inflammation, it belongs to salivation caused by angular stomatitis; If accompanied by oral mucosal congestion or ulceration, refusal to eat, irritability, it is called salivation caused by stomatitis; If accompanied by atrophy of facial muscles on one or both sides and weakness in chewing, it is indigestion and salivation caused by intestinal ascaris; If accompanied by mental retardation and dementia, it is caused by the hypoplasia of the cranial nerve system. The above pathological salivation needs to be examined and treated in the hospital. Generally speaking, if the primary cause is eliminated, the child's salivation will be improved or recovered. Because saliva contains digestive enzymes and other substances, it has a certain stimulating effect on the skin. Children who often drool, because saliva often wets the skin of chin and other parts, will also cause local skin redness and even erosion and peeling. Therefore, local care is very important: (1) A soft and loose dressing can be put on the neck to receive and absorb drooling, and it should be changed frequently; (2) Wash the face, jaw and neck with warm water frequently, and apply grease to protect the skin in cold season.
