CPT® Code 31380

A partial laryngectomy, commonly known as a hemilaryngectomy, is a surgical procedure that involves the removal of a portion of the larynx, which is the voice box located in the throat. This procedure is typically indicated for patients with laryngeal cancer, particularly when the cancer is localized to one side of the larynx. The term "hemilaryngectomy" refers to the fact that only a part of the larynx is excised, as opposed to a total laryngectomy, which involves the complete removal of the larynx. The procedure can be performed in different planes, specifically horizontal or vertical, depending on the location and extent of the cancer. In the case of an antero-vertical hemilaryngectomy, which is represented by CPT® Code 31380, the surgical approach involves excising tissue from the anterior aspect of the larynx, including the anterior commissure, which is the area where the vocal cords meet. This type of hemilaryngectomy may also involve the removal of part of the contralateral vocal cord, thereby affecting the patient's voice and swallowing function. Prior to the surgery, a tracheostomy may be performed to facilitate anesthesia and ensure the patient's airway is secure during the procedure. The surgical technique requires careful dissection and resection to minimize damage to surrounding structures while effectively removing the cancerous tissue.
