Abstract

This chapter discusses direct laryngoscopy where the larynx is visualised directly with the help of a rigid direct laryngoscope. Hidden areas of larynx which are not seen with indirect laryngoscopy like anterior commissure, ventricles, and subglottis are visualized better with direct laryngoscopy. IDL gives inverted 2D image whereas D/L scopy provides 3D direct visualization of larynx. Some important indications for D/L are for biopsy; for finding the nature and extent of growth; for removal of benign lesions of vocal cords; for foreign bodies’ removal and for endotracheal intubation. Suspension laryngoscopy is used for performing therapeutic surgery on vocal cords like removal of polypi, nodules, papilloma, etc. Fibreoptic flexible laryngoscopy is an OPD procedure and is done in patients with trismus; difficulty in indirect laryngoscopy and in uncooperative children. Supine position with extension of head and flexion of the neck is called Boyce’s position.
