Adenoids are glands located in the posterior pharyngeal wall. Normal adenoids will develop to the maximum at the age of 7, and then gradually degenerate and shrink. If the adenoids proliferate pathologically due to repeated stimulation of inflammation, it will affect children's breathing, maxillofacial development and children's growth and development.
Because children's nasopharynx is relatively narrow, adenoids will cause upper respiratory tract stenosis and hinder nasal breathing, mainly manifested as nasal congestion, and children will gradually form the habit of oral breathing. However, the mouth-opening breathing airflow impacts the hard palate, which affects the normal decline of the hard palate and forms a high arch of the hard palate. At the same time, the position of the tongue body decreases, which leads to the loss of support of the upper dental arch. The strength of buccal muscle will make the lateral arch of upper teeth underdeveloped, the posterior segment of maxilla narrow, the posterior teeth lock and the upper incisors float forward. In order to keep breathing unobstructed, some children often stretch their tongues forward and drive their mandibles forward, resulting in malocclusion of their front teeth and protrusion of their mandibles.
Therefore, when children have problems such as oral dyspnea and uneven teeth, they should first go to the otolaryngology department to check whether there is upper respiratory tract obstruction caused by adenoid hypertrophy. After adenoidectomy, correcting teeth can have obvious effect.
