Abstract
A 22-years-old male complained of neck pain while using a lawn mower. He found a skin injury on the front of his neck. Computed tomography discovered a foreign body within the thyroid cartilage, which did not reach to the membrane of the larynx. He underwent a “thyrotomy” and a tracheostomy under general anesthesia. We found a foreign body that was burying under the thyroarytenoid muscle. It was made of metal and was 1 cm length. No functional disturbance was observed after the surgery.
