The easiest way to treat children with nasal mucosa erosion is to apply edible sesame oil to the child’s nasal mucosa to lubricate it and promote healing of the nasal mucosa. If the child’s nasal mucosa does not improve after symptomatic treatment, consider applying erythromycin ointment to the surface of the broken mucosa for anti-inflammatory treatment and to reduce the child’s painful symptoms to avoid the formation of dry scabs. It is also important to warn your child not to reach inside the nostril with his hand and snap the nasal clip, as this will aggravate the nasal mucosa erosion and may even lead to nosebleeds. The active treatment for about 1 week will improve the situation of nasal mucosa erosion in children, and the child should be allowed to eat more fresh vegetables and fruits.
