If a neck cancer affects the thyroid cartilage or the thyrohyoid membrane, it may result in a spreading of the tumor from the laryngeal area into the soft neck tissues. If a cancer deeply invades the area known as the paraglottic space after passing through the thyrohyoid membrane, it will not face any more barriers…
