Laryngoscopy

 

an instrumental method of examining the larynx through the oral cavity.

There are two types of laryngoscopy: indirect (mirror) and direct. Indirect laryngoscopy is performed with a round laryngeal mirror (16 to 27 mm in diameter) in a metal rim attached to a metal rod at an angle of 120°. A frontal reflector is used to direct a light beam to the laryngeal mirror from an artificial source. Direct laryngoscopy is performed with special medical instruments, or laryngoscopes, which allow one to examine the larynx directly. The method is used in cases where the indirect approach proves inadequate or where the site of examination or surgical intervention proves inaccessible. Direct laryngoscopy is performed under narcosis where indicated.
