Partial Laryngectomy for T3 Glottic Cancer

Abstract

In a partial laryngectomy for T3 glottic cancer, a new method was developed for reconstructing the defects of the arytenoid region and the cricoid arch using parts of the thyroid cartilage and hyoid bone. After removal of the arytenoid region including the arytenoid cartilage and a periarticular region of the cricoid cartilage, a lateral half of the thyroid cartilage on the affected side, attached to the thyropharyngeal and sternothyroid muscles was utilized in the construction of a posterior-lateral wall of the larynx by way of suturing it with the incised end of the cricoid cartilage. After resecting the subglottis with an arch of the cricoid cartilage, a segmental defect of the cricoid cartilage was bridged by using half of the hyoid bone connecting to the sternohyoid muscle. Raw surfaces of the thyroid cartilage and the hyoid bone were covered with skin flaps of the anterior neck. This surgery was performed for a patient with T3 glottic cancer. Two months after surgery, the stoma was closed without respiratory disturbance. Normal food intake was possible. A hoarse voice remained, but phonatory function was fairly good.
