Comparative StudyThe relationship between the diameters of the adult cricoid ring and main tracheobronchial tree: a cadaver study to investigate the basis for double-lumen tube selection.
Previous investigation of the adult cadaver larynx has shown that the cricoid diameter never exceeds that of the glottis. This further analysis looks at the anatomic relationships between the diameter of the cricoid ring and those of the main tracheobronchial tree to discover how they relate to double-lumen tube selection. ⋯ The dimensions of the cricoid ring best define those of the main bronchi. Knowing its diameter should assist anesthesiologists with double-lumen tube selection.
