For the lymphoid follicular hyperplasia caused by chronic pharyngolaryngitis mostly choose surgical treatment and physical therapy to eliminate. Chronic hypertrophic pharyngolaryngitis is often manifested as mucosal congestion and thickening, with extensive submucosal connective and lymphatic tissue hyperplasia, and lymphatic tissue hyperplasia around the mucous glands, forming multiple granular elevations in the posterior pharyngeal wall. Hyperplasia and hypertrophy of lymphoid tissues in the lateral pharyngeal cords are common and appear as striated cords. For hyperplastic lymphoid follicles, laser and low temperature plasma can be used, and if the lymphoid follicle hyperplasia is extensive, the treatment should be carried out in stages. Drugs (silver nitrate), freezing or electrocoagulation can also be used, but the treatment should not be too extensive. When the follicular hyperplasia caused by chronic laryngitis needs to be treated, a specialist should recommend a suitable method according to the degree of the disease.
