Cordectomy is a surgical procedure primarily used for the removal of early-stage (Stage 1-2) cancers that affect limited sections of the vocal cords or larynx. Laryngeal cancer, a common type of head and neck cancer, can originate in any part of the larynx. Early detection significantly improves the chances of cure, often through the complete removal of only the cancerous area. A key objective of treatment, especially in early stages, is to preserve the larynx's essential functions of voice and swallowing.
For early-stage tumors, surgery (such as cordectomy) or radiotherapy alone may be sufficient for treatment. However, larger or more advanced tumors may necessitate more extensive treatments, including total laryngectomy, chemotherapy, and radiotherapy.
The larynx, commonly known as the voice box, houses the vocal cords responsible for speech. It is anatomically divided into three main regions:
* Glottis: The middle section containing the vocal cords.
* Supraglottis: The region above the vocal cords.
* Subglottis: The area below the vocal cords, connecting the larynx to the trachea (windpipe).
Cordectomy is a frequently chosen treatment option for tumors located in the glottis due to the excellent surgical visualization it typically allows. It can also be applied to appropriate, limited early-stage supraglottic tumors.
Laser cordectomy is often reserved for patients with early-stage tumors classified as T1 or T2.
* T1: Refers to a tumor confined to the vocal cords without impairing their movement. A tumor on one vocal cord is designated T1a, while a tumor affecting both vocal cords is T1b.
* T2: Indicates a tumor that has spread to an adjacent area near the vocal cord. Under specific conditions, laser cordectomy may still be a viable treatment option for T2 tumors.
