Adenoid hypertrophy is a mass of lymphoid tissue in the nasopharynx (located just above the posterior nostril, which is not easy to see), which is called adenoid hypertrophy when repeated inflammatory stimulation leads to gradual hyperplasia and blockage of the posterior nostril, causing a series of related bed symptoms. Adenoid hypertrophy is most commonly seen in children between the ages of 3 and 5, and is rare in adults. Adenoid hypertrophy without clinical symptoms is physiological hypertrophy, mostly seen in children aged 6 to 7 years old, and gradually shrinks after the age of 10 years old, and basically disappears in adults. Clinical manifestations: mainly cause ear, nasopharynx and throat symptoms. 1, ear symptoms: due to adenoid hypertrophy, pressure blocking the pharyngeal tube pharyngeal opening, causing secretory otitis media, self-conscious ear blockage, such as swimming in the ear canal into the general water; some patients shake their heads, self-conscious water flow in the ear, you can hear the flow of water people sound. At the same time, it leads to hearing loss and tinnitus, and sometimes causes purulent otitis media and tympanic membrane perforation, with the surface being ear pain and pus flowing from the external ear canal. 2, nasal symptoms mainly manifested as nasal congestion, runny nose, heavy nasal sound when speaking, snoring and open mouth breathing during sleep (the most common symptoms, according to rhinitis, sinusitis treatment for more than 10 days when the effect is not good, should consider adenoid hypertrophy can be), in serious cases caused by obstructive sleep apnea hypoventilation syndrome, causing persistent brain hypoxia, will affect the neurological development of the brain and intellectual development, manifested as the affected children This can affect the neurological development of the brain and intellectual development, which can be manifested as a decrease in academic performance, memory loss, inattention and irritability. 3. Throat and lower respiratory tract symptoms: paroxysmal cough, coughing and other symptoms of tracheitis and bronchitis, which cannot be cured for a long time. 4, abnormal development of jaw and facial bones, mainly caused by long-term open-mouth breathing, the surface of the maxilla becomes longer, the palate is high arched, the teeth are not aligned, the upper incisors protrude (commonly known as the teeth), the lips are thick, lack of expression, the so-called “adenoid face”. Once the adenoid face is formed, the facial deformity cannot be restored to normal even if the adenoids are removed surgically. 5 Systemic symptoms mainly include emaciation, weakness, slow reaction, inattentiveness, night terrors, teeth grinding, urination, etc. Diagnosis: Nasal endoscopy and CT examination can mostly confirm the diagnosis. Treatment: 1. General treatment Pay attention to nutrition, prevent colds, improve immunity, and actively treat the original disease. With the age of diagnosis, the remote body will gradually atrophy, the disease may basketball to remission or symptoms disappear. 2.Surgical treatment If conservative treatment is ineffective, adenoids should be removed through the mouth or nasal endoscopy as soon as possible. If the tonsils are not clearly indicated for surgery, adenoidectomy can be performed alone. CT image of postoperative adenoid hypertrophy. Postoperative and normal nasopharyngeal images of children
