Laryngoscopy is mainly used to check whether lesions occur in the pharynx and larynx of the organism. It is recommended for patients who are older than 60 years old and who have smoked and drunk alcohol for a long time in their daily lives and have repeated hoarseness of voice, as the examination is generally quick and does not cause intolerable discomfort. At present, laryngoscopy is clinically divided into two types of hose and rigid tube scopes. The hose-scope can be examined in a sitting position or lying down. The hose-scope is very slim and the examination is very comfortable and can be completed successfully without anesthesia, usually in about three minutes, and is less painful. Dural tube scope is also known clinically as dynamic laryngoscopy, which is mainly used to diagnose diseases of the organism’s voice, such as the detection of subtle lesions of the vocal cords, and is very painless. Usually, local anesthesia is administered to the body before the laryngoscopy, and the nostrils and throat are sprayed with anesthetics in turn, and the patient usually does not experience discomfort during the procedure. In the current clinical electronic laryngoscopy is more widely used, convenient and easy, the operation time is very short, the irritation to the body is very small, can do early detection of disease, early diagnosis, to provide a reliable basis for treatment, but also to eliminate everyone’s fear of laryngoscopy. In short, laryngoscopy is not painful, and it is recommended that patients with laryngeal discomfort go to the hospital for examination.
