The following examinations can be done when examining the tonsils: 1. tongue depressor examination: the tonsils are located in the pharynx and can usually be effectively observed in most areas of the conductor by a simple tongue depressor examination. 2. microscopic examination: some patients may have more enlarged tonsils, which may lead to narrowing of the pharyngeal cavity, and further indirect laryngoscopy, as well as electronic laryngoscopy, is often required. 3.Pathological examination: If the tonsils are abnormally hyperplastic and elevated, further biopsy pathological examination can be done as appropriate to help clarify the nature of the pathology. 4.Blood tests: For acute inflammatory conditions of the tonsils, a biopsy can also be done to help clarify the nature of the pathology. In the case of acute inflammation, the blood test can be further improved to check the elevation of infection indicators.
