Here we know about adenoids: Under normal physiological conditions, the adenoids are located in the nasopharynx, which is behind the nasal cavity. The adenoids develop the most when children are 6 – 7 years old, and gradually shrink after puberty, and basically disappear in adults. Adults are rare. The pathological hyperplasia of adenoids occurs as a result of repeated inflammation in the nasopharynx and adjacent areas or in the adenoids themselves. Adenoid hypertrophy can cause symptoms in the ear, nose, pharynx and throat. Ear: The eustachian tube is obstructed, and the resulting secretory otitis media can lead to hearing loss and tinnitus in children. Sometimes it can also cause purulent otitis media. Nasal symptoms: Often complicated by rhinitis and sinusitis. An occlusive nasal sound occurs when speaking and snoring during sleep. When you see this, you will know why the outpatient child’s nose is not ventilated and why he snores at night. In fact, the child’s long-term open-mouth breathing affects the development of facial bones, the maxilla becomes longer, the jaw bone is high arched, the teeth are not aligned, the upper incisors protrude, the lips are thick, lack of expression, and the so-called “adenoid face” appears. A nasopharyngeal x-ray, or CT scan, can help us make a diagnosis. Then the appropriate treatment or removal of the adenoids can cure the child’s disease. So I would like to tell ENT doctors that when you see a child with a blocked nose and hearing loss, you might want to check the adenoids in the nasopharynx. The diagnosis is clear and the patient is able to be diagnosed and treated.
