Many people know that the tonsils in the mouth will often increase in size and affect the throat, making children inflamed tonsils and thus colds and fevers, recently experts have discovered a second gland that often makes children sick – “adenoids”, the onset of which can cause children to change their temperament and The adenoids hidden in the back of the nasal cavity are actually a lymphatic tissue similar to the tonsils, which is unknown even to many doctors in other departments, except for ENT doctors, and the general public knows very little about it. With the changes in children’s nutritional status and dietary habits, the number of children with various diseases caused by adenoids is on the rise. Once adenoid hyperplasia is enlarged, it is likely to induce secretory otitis media, leading to hearing loss, inattention, coughing, chronic sinusitis, etc. In serious cases, snoring during sleep can also occur, affecting the normal development of the child’s teeth, facial bones and other appearance, presenting an “adenoidal appearance”. When your child has a cough, chronic sinusitis, snoring and other symptoms that are not cured in the relevant departments, you may want to pay attention to whether the adenoids in the back of your child’s nasal cavity are inflamed and hyperplastic, and you should promptly go to the ENT department of a regular hospital for professional examination and treatment.
