A laryngotomy, also known as a thyrotomy or laryngofissure, is a surgical procedure that involves making an incision in the larynx to access and remove pathological structures such as tumors, laryngoceles, or vocal cords. This procedure is indicated when there is a need to excise a tumor that may be obstructing the airway or affecting vocal function, or to remove a laryngocele, which is a cystic dilation of the laryngeal saccule that can cause respiratory distress or other complications. The surgery begins with an incision over the thyroid cartilage, which is then split in the midline using an oscillating saw to expose the larynx. Once the larynx is accessible, the surgeon identifies the tumor or laryngocele and excises it, ensuring to remove a margin of healthy tissue to minimize the risk of recurrence. In cases where the vocal cord is involved, a cordectomy is performed, which entails the complete removal of the affected vocal cord along with surrounding healthy tissue. After the necessary excisions are completed, the surgical wound in the larynx is meticulously closed with sutures to promote healing and restore the integrity of the airway.
