Lymphatic follicular hyperplasia in the pharynx can be treated medically or surgically. Lymphatic follicles in the pharynx are an important part of the pharyngeal lymphatic ring and are widely distributed in the posterior pharyngeal wall, lateral pharyngeal cord, tongue root and mucous membrane of the pharynx. When chronic inflammation, prolonged intake of spicy and stimulating diet, or gastrointestinal dysfunction such as acid reflux, acidic water and acid gas stimulation are encountered, the lymphatic follicles will significantly proliferate and produce edema. On examination, there are small, soft, smooth surface, painless to touch, light red, uneven particles on the posterior pharyngeal wall, lateral pharyngeal cord, tongue root, and epiglottis. If the foreign body sensation is not too obvious, the patient can be treated by eliminating the causes, such as a light diet, no spicy and stimulating food, adjusting the gastrointestinal function, taking oral loxacillin and morpholine, as well as oral lorazepam and dibutyl pellets. If the patient is very sensitive to foreign body sensation in the throat, surgical treatment is required, which can be performed by microwave or laser to remove the lymphatic follicles.
