A laryngoplasty, as defined by CPT® Code 31588, is a surgical procedure aimed at repairing or reconstructing the larynx, specifically for conditions that do not include laryngeal web, laryngeal stenosis, or the reduction of a fracture. This procedure is utilized in cases where other techniques, such as a cricoid split, are not applicable. Common scenarios for performing a laryngoplasty include addressing burn injuries to the larynx, reconstructing the larynx following a partial laryngectomy, or performing medialization laryngoplasty to treat laryngeal paralysis. The procedure begins with a horizontal incision made over the larynx, typically at the level of the cricothyroid membrane, allowing for adequate exposure of the laryngeal structures. The surgical approach involves creating a subplatysmal apron flap, which is elevated to provide a clear view of the larynx. The strap muscles are then divided and retracted to facilitate access. Depending on the specific needs of the patient, laryngeal tissue may be excised, and various flaps or grafts can be employed to repair any defects. After the repair is completed, a drain is placed in the neck, and the overlying soft tissue and skin are meticulously closed in layers to promote healing.
