Background:
Videolaryngoscopy is commonly used by anesthesiologists to manage difficult airways. Recently otolaryngologists have reported use in select procedures; to date there is limited evaluation in head and neck surgery.
Materials And Methods:
Patients who underwent direct laryngoscopy (DL) with use of GlideScope videolaryngoscopy (GVL) were retrospectively identified from a tertiary care Veterans Affairs hospital. GVL was used to assist or replace traditional laryngoscopes for diagnostic and therapeutic procedures.
Results:
Nineteen patients (48-83 years old) underwent 21 procedures. Difficult endotracheal intubation was reported in 53% of patients. GVL replaced traditional DL in 76% of cases, assisted evaluation prior to traditional DL in 10%, and rescued failed traditional DL in 14%. No complications occurred. Three indications for GVL were identified.
Discussion:
GVL was safe in our experience and provides unique benefits in selected scenarios in head and neck surgery. Otolaryngologists can consider videolaryngoscopy as a complement to traditional DL.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
