Proliferative gland hypertrophy is the enlargement or inflammation of the proliferative gland. The gland is a normal tissue located at the back of the nasal cavity and is a lymphatic tissue in the pharynx, like the palatine tonsils at the back of the mouth. Hyperplasia occurs only in children before puberty, and is a condition in which the enlargement occurs above the tonsils, near the back of the pharynx. So, how to diagnose whether a child has hyperplasia of the acromegaly gland? 1, pediatric snoring: children with enlarged proliferative glands block the posterior nostril and pharyngeal pharyngeal opening, and symptoms such as otorhinopharyngeal can occur. The symptoms are open-mouth breathing during sleep, snoring at the back of the tongue root, restless sleep at night, nasal secretions, occlusive nasal sounds when speaking, and slurred speech. Because of long-term open-mouth breathing, the facial bone development is impaired, the maxilla becomes longer, the hard palate is high arched, the teeth are uneven, the upper incisors are exposed, the lips are thick, the face lacks expression, and there is dementia, forming an “adenoid face”. The ataxic movement between swallowing and breathing is dysfunctional, and choking and coughing often occur. The downward flow of secretions irritates the mucous membrane of the respiratory tract and makes it easy to suffer from bronchitis. Non-suppurative otitis media caused by obstruction of the eustachian tube leads to hearing loss, tympanic membrane invagination or middle ear effusion. Due to long-term hypoxia, it can even lead to pulmonary heart disease. 2. Local symptoms: (1) Ear symptoms: obstruction of the pharyngeal opening of the eustachian tube will be complicated by secretory otitis media, leading to hearing loss and tinnitus, and sometimes purulent otitis media; (2) Nasal symptoms: often complicated by rhinitis and sinusitis, with symptoms such as nasal congestion and runny nose; (3) Throat and lower respiratory tract symptoms: secretions irritate the respiratory tract mucosa, often causing paroxysmal cough.
