When coughing up granular substances, it is necessary to consider the common cases of acute attacks of chronic tonsillitis, acute tonsillitis, etc. After the inflammatory reaction of the tonsils, especially when infected by purulent bacteria, there is an exudation of inflammatory secretions. Pus from the tonsils causes the pus to be relatively viscous, and lacking moisture, it coagulates into a solid. The surface of the tonsils has a very large number of crypts, and the viscous solids become embedded in the crypts. When the object in the crypt is coughed out with violent coughing, granules are coughed up. It is usually treated with nebulized inhalation and antibiotics, and if necessary, the granules can be removed directly with forceps under the direction of the doctor.
