Supracricoid laryngectomy

Supracricoid laryngectomy includes removal of the entire supraglottis, the false and true vocal cords, and the thyroid cartilage including the paraglottic and preepiglottic spaces. In addition, one arytenoid may be resected. The cricoid cartilage, hyoid bone, and at least one arytenoid are saved. Phonatory and swallowing function is maintained by the movement of the spared arytenoid against the tongue base. Respiratory function is dependent on the preservation of the cricoid cartilage. Preservation of these laryngeal functions form the basis of conservation(organ-preserving) surgery.Click here to read more
