Indirect laryngoscopy or fiberoptic laryngoscopy is usually used for laryngeal examination, which can find out the lesions of the vocal cords, epiglottis and the pyriform fossa. 2. Direct vision examination: this examination is to utilize the frontal mirror reflection, press the tongue with tongue depressor to fully expose the pharynx, which can observe whether the pharyngeal mucosa is congested and swollen, whether the tonsils are enlarged, and whether there is herpes in the oral cavity. 3.

If you find a foreign body sensation in the pharynx or pain in the pharynx, you need to go to the hospital for further consultation and examination and treatment under the guidance of a physician to avoid delaying your condition.
