Laryngoscopy: due to the deep location of the larynx, physiological structure of the complex, can not be directly peeped, laryngeal examination requires the use of some special inspection methods, such as indirect laryngoscopy, direct laryngoscopy, fiber laryngoscopy, electronic laryngoscopy, stroboscopic laryngoscopy, ultra-high-speed cinematography, sonogram or phonocardiogram.
Laryngoscopy (laryngoscopy, laryngoscopy, laryngoscopy, laryngoscopy) is an endoscopic examination of a part of the throat. Laryngoscopy is a medical procedure that is used to obtain a visual map of the internal tissues of the body. For example, the vocal cords and vocal folds are visualized. Laryngoscopy is performed to assist in tracheal intubation during general anaesthesia or cardiopulmonary resuscitation, or to perform surgical procedures on the larynx or other parts of the upper trachea and bronchi.
Extended information:
Direct laryngoscopy of the larynx involves picking up the base of the tongue and epiglottis with a direct laryngoscope, and is not considered to be a routine laryngeal examination because it is an invasive part of laryngeal examination. It is not a routine examination of the larynx because it is an invasive examination of the larynx and is usually difficult for the patient to tolerate under mucosal anesthesia, and usually requires hospitalization under general anesthesia. Direct laryngoscopy provides a detailed understanding of the structural abnormalities of the larynx, clarifies the location and extent of the lesion, and performs a biopsy of the diseased tissue if necessary. Direct laryngoscopy does not provide a functional picture of the larynx. Since the development of fiberoptic laryngoscopy and electronic laryngoscopy, direct laryngoscopy as a means of examination of its application is becoming smaller, but as a means of surgical operation is widely used in clinical practice.
