Laryngoscopes

The regular type of laryngoscope shown in Fig. I

(A, B, C) is made in adult's, child's, and infant's sizes. The

instruments have a removable slide on the top of the tubular

portion of the speculum to allow the removal of the laryngoscope

after the insertion of the bronchoscope through it. The infant size

is made in two forms, one with, the other without a removable slide;

with either form the larynx of an infant can be
exposed in but a few

seconds and a definite diagnosis made, without anesthesia, general or

local; a thing possible by no other method. For operative work on the

larynx of adults, such as the removal of benign growths, particularly

when these are situated in the anterior portion of the larynx, a

special tubular laryngoscope having a heart-shaped lumen and a

beveled tip is used. With this instrument the anterior commissure is

readily exposed, and because of this it is named the anterior

commissure laryngoscope (Fig. 1, D). The tip of the anterior

commissure laryngoscope can be used to expose either ventricle of the

larynx by lifting the ventricular band, or it may be passed through

the adult glottis for work in the subglottic region. This instrument

may also be used as an esophageal speculum and as a pleuroscope. A

side-slide laryngoscope, used with or without the slide, is

occasionally useful.
