lateral cricoarytenoid การใช้
- Physiologically, the glottis is closed by intrinsic laryngeal muscles such as the lateral cricoarytenoid, thyroarytenoid, and interarytenoid muscles.
- A suture is used to emulate the action of the lateral cricoarytenoid muscle and position the paralyzed vocal cord closer to the midline.
- The phonatory muscles are divided into adductors ( lateral cricoarytenoid muscles, arytenoid muscles ) and tensors ( cricothyroid muscles, thyroarytenoid muscles ).
- The suture placed in the arytenoid adduction procedure mimics the action of the lateral cricoarytenoid muscle and pulls the vocal process of the arytenoid cartilage medially and inferiorly.
