Pharyngeal airway and digestive tract is a common pathway. Adult pharynx is wide and the next one on the narrow, little flat before and after the funnel-shaped muscular pipeline. From top to bottom respectively with nose, mouth and larynx interlinked, therefore, the pharynx is divided into the nasopharynx, oropharynx, and hypopharynx, pharynx is a common digestive and respiratory passage.
The pharyngeal structures in children and adults are different:
(1) Infant nasopharynx and pharynx is relatively small, and more vertical.
(2) The rich build-up of nasopharyngeal lymphoid tissue, and whose development is also different because of their age. The largest is about two tonsils, in the neonatal period, the palatal arch hidden in between the crypt and blood vessels have developed, to one end of the year, with the development of lymphoid tissues of the body gradually grow up, 4 ~ 10 growth reached a peak at the age of 14 to 15-year-old Shi You deterioration. Due to anatomical characteristics of the decision, angina is commonly found in school-age children, and infants under 1 year of age are very rare. Around the tonsils, there is diffuse lymphoid infiltration, pharynx posterior wall of particles shaped lymphoid follicles, the most notable one year old, then gradually shrink, and therefore infancy up to retropharyngeal abscess. Tonsil has certain defense function, but when bacteria hidden deep in the crypt, when, and yet become a chronic infection of the lesions. Adenoids than the tonsils as early as the development, about 6 to 12 months that began to develop.
(3), Child Care syringes wide, short and straight, was the level of bits, therefore, after suffering from a cold complicated by otitis media.
