Indirect vs. direct laryngoscopy

Direct laryngoscopy refers to viewing the larynx directly, in a straight line, through a hollow, lighted tube, with the patient typically under general anesthesia. Indirect laryngoscopy refers to visualization of the larynx with the patient sitting in a chair, by using a mirror, fiberscope, videoendoscope, or laryngeal telescope more in the manner of a perisocope that “looks around the corner” – in this case, the base of the tongue.
