The white granular material in the patient’s throat is often caused by chronic inflammation of the tonsils. The white granular material is a pus-like secretion trapped in the crypt on the surface of the tonsils, which is often a product of chronic inflammation of the tonsils and is often mixed with food residues. The tonsils of patients often have a certain degree of enlargement due to chronic inflammation, and the crypt opening on the surface of the tonsils may also be enlarged, making it easy to embed some food residues and secretions and mixtures, which may lead to a certain degree of throat blockage and foreign body sensation, as well as a sense of odor or foul odor in the oral cavity, and appropriate cleaning can be taken when there are more secretions. The patient may also experience a sense of odor or foul taste in the throat.
