A. Why do enlarged tonsils need to be surgically removed? Tonsils are lymphoid organs of the body, located at the meeting point of the digestive and respiratory tracts, i.e. the pharynx. The mucous membrane here contains a large number of lymphatic tissues, is often exposed to antigens to cause a local immune response, when our body is infected, tonsils can produce lymphocytes and antibodies, so it has anti-bacterial and anti-viral defense function. Under normal circumstances, due to the epithelial integrity of the surface of the tonsils and mucous glands continue to secrete, bacteria can be discharged along with the shedding of epithelial cells from the crypt mouth, therefore maintaining the health of the body. When the body due to excessive fatigue, cold and other reasons to make resistance decline, epithelial defense function is weakened, the gland secretion function is reduced, the tonsils will suffer from bacterial infection and inflammation. If the tonsillitis recurrence, or long have a tumor, resulting in tonsil hypertrophy, will lead to breathing problems, can consider the tonsils with surgery to remove. What causes tonsil hypertrophy? 1, due to bacteria and secretions accumulated in the tonsil nest. The causative agent is mainly streptococcus or staphylococcus. 2, secondary to some acute infectious diseases such as scarlet fever, diphtheria, influenza, measles and so on. 3.Tumor in the tonsils. Third, often involve other parts of the body! 1, ear symptoms: due to tonsil hypertrophy and nasopharyngeal inflammatory secretion accumulation, so that the Eustachian tube pharyngopharynx is blocked, can be complicated by non-purulent or purulent otitis media, resulting in hearing loss and tinnitus, ear stuffiness. 2, nasal symptoms: tonsillar hypertrophy often complicate rhinitis, sinusitis. Children with nasal congestion, runny nose, open-mouth breathing, salivation, speech with occlusive nasal sound, sleep snoring and other symptoms. 3, respiratory tract infection symptoms: due to the inflammation of the secretion stimulation of respiratory mucosa, often caused by pharyngolaryngeal, tracheal and bronchitis, so the patient may appear pharyngeal discomfort, voice changes, coughing and spitting, shortness of breath, low-grade fever and other symptoms. 4, “adenoid face”: due to long-term open-mouth breathing, affecting the development of the child’s facial bones, maxillary narrowing, hard palate high arch narrowing. Teeth protruding, irregular teeth, bad bite, sagging jaw, thick lips, upturned upper lip, hanging lower lip, lower canthus, nasolabial sulcus is shallow and flat. The so-called “adenoid face” is characterized by mental depression, dull and obtuse facial expression.
