An Introduction to Anterior Commissure Laryngoscope

Posted on

When visiting your physician with presenting symptoms of an intense earache, swallowing difficulties, a mass or a lump in the region of the throat, a persistent cough or coughing up blood, your physician will most likely recommend performing a laryngoscopy. This procedure, which introduces an endoscope through the mouth into the larynx, is done to allow your physician to view your particular throat anatomy using an anterior commissure laryngoscope.

Throat Anatomy

The delicate region known as the larynx is also home to the thyroid gland and cartilage as well as the true and false vocal cords. The larynx is located anterior the pharynx in the throat. On opposing sides of the larynx, the vocal cords occupy the space beneath the hyoid bone and above the trachea. The anterior commissure of the larynx is the area where the vocal cords meet from the right and left at the front-most portion of the larynx.

How Is a Laryngoscope Used?

The primary purpose of this particular endoscope is to view the otherwise unseen anatomy of the larynx in its entirety. When performing a direct or indirect flexible laryngoscopy, the scope is introduced through either the nasal cavity or the throat. The specialist will instill a numbing anesthesia and perform the procedure while the patient is awake. However, when using an anterior commissure laryngoscope, like one found from the Medical Device Store, the patient will be given general anesthesia as this rigid endoscope is deemed more invasive. Once the scope is introduced through the mouth and into the larynx, the surgeon can view the laryngeal anatomy with more precision.

When Is It Used?

This particular laryngoscope, which was patented in 1991, is used by specialists in addition to a binocular operating microscope. The binocular microscope attaches to the laryngoscope for amplified viewing. By using this microscope and magnifying the area in question, a surgeon can view suspected pathology. This enhanced viewing procedure allows the surgeon to then remove any polyps in question or take biopsies of this region of the larynx when cancer is suspected.

In summary, this procedural laryngoscope is typically used for more advanced laryngeal procedures. Although a patient will need to undergo general anesthesia for procedures utilizing this endoscope, the benefits associated with this advanced procedure include precision in identifying and removing pathology of the larynx in a setting that provides for better protection of the delicate vocal cords.
