Dissection of anterior and lateral regions of neck
Larynx; thyroarytenoid and lateral cricoarytenoid muscles; anastomosis of superior and inferior laryngeal nerves, left anterolateral view
The left lamina of the thyroid cartilage has been cut and reflected posteriorly. The left cricothyroid joint (23) has been opened.
