Bronchoscopic Anatomy

Abstract

A functional understanding of normal tracheobronchial anatomy as well as its clinically relevant variations is essential to effective, safe perioperative anesthetic evaluation and management for thoracic procedures. This chapter reviews the anatomy of the airway and lung structures that are encountered during basic bronchoscopy. The larynx, trachea, and tracheobronchial tree, including right and left lung and bronchial anatomy and vascular supply to the trachea and bronchial tree, are presented in addition to key identifying features for each structure. Labeled illustrations and bronchoscopic images are provided for reference and clarity. The vascular supply is also described and depicted. This chapter includes possible anatomical and pathological variants that may be discovered during bronchoscopy.
