The examination of chronic lingual tonsillitis reveals hypertrophic lymphoid tissue at the root of the tongue, which is granular and covered with the root of the tongue, symmetrical on both sides or on one side. As a result of lymphoid follicular infection in the lingual tonsils, small yellowish-white punctate abscesses can be seen under the mucosa. Chronic lingual tonsillitis: If the tongue is pressed with a tongue depressor or indirect laryngoscopy, hypertrophic lymphoid tissue can be seen at the root of the tongue, granularly covering the root of the tongue, symmetrical on both sides or on one side. In heavy cases, the lymphatic tissue is covered with the valley of the epiglottis and can also extend to the pharynx and connect with the tonsils. As the lymphatic follicles in the lingual tonsils are infected, small yellowish-white punctate abscesses can be seen under the mucosa. Chronic tonsillitis: Examination reveals chronic congestion of the linguopalatine arch and tonsils with dark red mucosa. The tonsils are mostly inflammatory adhesions to the anterior and posterior arches; the surface is either flat, uneven, or lobulated. Sometimes linear scarring, enlarged crypt openings and cheese-like plugs or submucosal yellowish-white spots are seen. When the tonsils are squeezed with a tongue depressor on the lateral side of the lingual-palatal arch, secretions may spill from the crypt opening. Enlarged lymph nodes can often be palpated under the angle of the mandible.
