Causes Due to bacterial and viral infections, with bacterial infections being more common. The pathogenic bacteria are mostly Streptococcus hemolyticus, Staphylococcus, and Pneumococcus. Symptoms 1. Ear symptoms: Due to the accumulation of tonsillar hypertrophy and inflammatory secretions in the nasopharynx, the pharyngeal orifice of the eustachian tube is obstructed, which can be complicated by non-suppurative or suppurative otitis media, resulting in hearing loss and ear stuffiness. 2. Nasal symptoms: tonsillar hypertrophy is often complicated by rhinitis and sinusitis. Children have symptoms such as nasal congestion, runny nose, open-mouth breathing, salivation, speech with occlusive nasal sound, and sleep snoring. 3. “Adenoid face”: Due to long-term open-mouth breathing, the child’s facial bone development is affected, the upper jaw is narrow and the hard palate is high and narrow. The teeth are protruding, the teeth are uneven, the bite is bad, the lower jaw is drooping, the lips are thick, the upper lip is upturned, the lower lip is hanging, the outer canthus is pulled down, and the nasolabial fissure is shallow and flat. In addition, there is mental depression, dull and dull facial expression, which becomes the so-called “adenoid face”. The main clinical symptoms: 1, cause children to snore: tonsillar enlargement is an important cause of snoring in children. The enlarged tonsils cause obstruction of the upper airway, resulting in severe snoring, poor swallowing and slurred pronunciation. In severe cases of snoring in children, the airway can be completely obstructed, resulting in apnea and even sudden death! Therefore, parents should not take it lightly! 2, tonsil enlargement can easily cause systemic diseases, become focal tonsils, triggering conditions such as nephritis. 3, recurrent attacks of enlarged tonsils can cause recurrent attacks of rhinitis, otitis media, bronchitis, etc. or long-lasting treatment. 4, excessive enlargement of the tonsils, resulting in poor breathing, thus long-term rest and chronic lack of oxygen, will affect the child’s physical development. 5, causing the child “adenoid face”: due to long-term open-mouth breathing, affecting the child’s facial bone development, the upper jaw is narrow, the hard palate high arch narrowing. The teeth protrude, the teeth do not line up, the bite is bad, the lower jaw droops, the lips are thick, the upper lip is upturned, the lower lip hangs, the outer canthus is pulled down, and the nasolabial fissure is shallow and flat. In addition, there is mental depression, dull and dull facial expression, which is called “adenoid face”. The shortcomings of this local treatment are that it is only anti-inflammatory and does not remove the bacteria in the tonsillar sockets, once the body’s resistance decreases it is easy to have recurrent attacks and form chronic lesions over time. 2, surgery: tonsil adenoid hypertrophy, and affect the breathing, and tonsils often inflammation, etc., can be considered surgical treatment, can use low-temperature plasma ablation, efficient, high safety factor.
