What Is the Larynx?

The larynx, or voice box, is divided into three areas:

  • Glottis — the vocal cords
  • Supraglottis — the area above the vocal cords, including the epiglottis, which closes off when you swallow
  • Subglottis — the area below the vocal cords

The larynx sits above the trachea at the entrance to the lungs. The larynx makes sound for speaking and protects the airway during swallowing. The vocal cords change the sound and pitch of the voice. They close tightly when you swallow and open up to let you breathe.

U.S. News & World Report ranks The Mount Sinai Health System among the top 20 hospitals in the United States for the treatment of ear, nose, and throat disease, including larynx cancer. Mount Sinai's larynx cancer specialists function as part of The Tisch Cancer Institute — a multi-disciplinary research and clinical care institution whose membership encompasses all Mount Sinai physicians and researchers whose work involves cancer.
