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.
