Pharyngitis refers to the inflammation of the mucous membrane of the throat, which can be acute or chronic. Clinically, it mainly presents symptoms such as throat pain and a foreign body sensation in the throat, along with other symptoms. Pharyngitis can generally be diagnosed through a local examination or laryngoscopy, which fulfills clinical requirements. For recurrent pharyngitis or clinically severe cases, an electronic laryngoscopy may be necessary to check for any growths in the pharynx or on the vocal cords, as this examination can clearly determine the condition and guide clinical treatment. Therefore, it is necessary to perform a laryngoscopy for pharyngitis.
