The nose is the beginning of the respiratory tract is gas out of the portal; the same time, my sense of smell organ. Adult children of the nasal structures and somewhat different:
(1) Because facial skull hypoplasia, my son's nose and nasal cavity is relatively short. Newborns and new-born children a few months almost no inferior meatus. Later, with age, facial skull, maxillary growth, as well as a tooth, a gradual lengthening of the nasal passages widen. To 4 years old, inferior meatus was fully formed.
(2) infants did not vibrissa, nasal soft and rich in blood vessels, and therefore vulnerable. Infection, because of congestive nasal swelling, often so narrow nose is more narrow, or even occlusion, difficulty in breathing occurs. Even the common cold, may also occur in infants breathing difficulties, refusal to milk, as well as irritability.
(3), underdeveloped sinuses of infants at birth, the frontal and ethmoid sinus Although formation, but very small, frontal and sphenoid sinus is completely undeveloped. Later, with age, face the gradual development of the skull and upper jaw, sinus gradually developed to complete. However, the development of the various sinuses are not fully consistent with, such as the maxillary sinus, increases rapidly after 2 years of age to 6 years old when wide and deep; ethmoid and maxillary sinus similar to the speed of development; the first 2 years after birth, the beginning frontal sinus the emergence of six years of age, such as pea-size, 12 ~ 13 years old when the development system; sphenoid sinus and nasal cavity to the 3-year-old when interlinked, 6-year-old began to rapidly increase when the chamber. Because the Child Care sinus poorly developed, so vulnerable to upper respiratory tract infection, but rarely cause sinusitis.
(4) The nasolacrimal duct in the early childhood years, a shorter, open the valve hypoplasia Department, located in the inner eye canthus. Therefore, upper respiratory tract infection in children is often invaded and conjunctiva, the eyelids appear red and swollen gum many other symptoms.
