If the tongue is pressed with tongue depressor or indirect laryngoscopy, hypertrophic lymphoid tissue can be seen at the root of the tongue, which is granular and covered with the tongue root, symmetrical on both sides or on one side. In severe cases, the lymphatic tissue is covered with the valley of the epiglottis and can also extend to the side of the pharynx to connect with the tonsils. Due to the lymphoid follicular infection in the lingual tonsils, small yellowish-white submucosal abscesses can be seen. It is distinguished from chronic tonsillitis. It is caused by the accumulation of bacteria and secretions in the tonsillar fossa. These accumulated bacteria continuously secrete toxins and spread throughout the body through the network of blood vessels surrounding the glandular fossa. Thus, the tonsils become the focus of many systemic diseases such as rheumatic fever and nephritis, which is where the danger lies. Actively treat inflammatory lesions of the respiratory tract, such as chronic pharyngitis and chronic tonsillitis, quit smoking and drinking, use less irritating food, and manage environmental pollution. Local rubbing of 5% to 10% silver nitrate or 1% iodine glycerin can often reduce symptoms.
