Glandular hypertrophy
Introduction
Introduction Proliferating lymphoid tissue hyperplasia occurs in children and can be physiological, or secondary to infection or allergic. The adenoid is a special gland located in the nasopharynx and does not have much practical effect. And now many children have a swollen gland that can block the respiratory tract. Surgery can be eradicated, proliferative gland hypertrophy can only occur in children before puberty, a disease that proliferates glandular hypertrophy, which is a disease that occurs above the tonsils and close to the back of the pharynx.

Nasal endoscopy
The diagnosis of adenoid enlargement is mainly to take the X-ray nasopharynx lateral radiograph, because it is difficult to obtain the cooperation of children in the examination of nasopharyngoscopy and nasopharynx, and the width of the nasopharyngeal cavity cannot be accurately measured. The degree of blockage. To do a good measurement of adenoids, you need to take a high-quality X-ray film. The following is the method of taking the lateral sinus of the nasopharynx.
The method of projecting the lateral lobes of the nasopharynx: the patient takes the sitting position or the standing side position, the head is slightly raised, so that the ear line is parallel to the ground, the sagittal plane is parallel to the cassette, and the center line passes through the front and the bottom of the outer ear hole. At the centimeter, the film distance is around 120CM.
Diagnosis
Differential diagnosis
Need to identify whether it is physiological or pathologically enlarged.
A disease that proliferates glandular hypertrophy occurs only in children before puberty, a disease that occurs above the tonsils and close to the back of the pharynx. Proliferating glands have the effect of assisting the body's defense system against respiratory infections, and only when they grow too fat will cause disease. Under normal circumstances, the adenoid begins to expand when the child is three years old. At this time, when the child is most susceptible to infection, the adenoid begins to expand at this time, perhaps to give the child more protection of the lungs and chest. When the child reached the age of five, the adenoid began to shrink, and by the time of youthful development, the adenoid had completely disappeared. But in a few cases, they continue to grow long, eventually blocking the airway from the nose to the pharynx, the tracheal opening from the middle ear to the nasal cavity, or both blocking it.
Hypertrophic adenoids block the eustachian tube and/or posterior nostrils, and obstruction of the eustachian tube often causes recurrent acute, chronic or secretory (slurry) otitis media (middle ear effusion); after obstruction, the nostrils can cause mouth breathing, obstructive Sleep apnea, occlusive nasal sounds and purulent discharge from the nostrils. Chronic paranasal sinusitis, clinically common chronic adenitis.
