A laryngoplasty is a surgical procedure that involves the modification of the larynx, specifically utilizing a technique known as cricoid split. This particular approach is characterized by the splitting of the cricoid cartilage, which is a vital structure that forms a complete ring around the trachea. The primary indication for performing this procedure is to address congenital subglottic stenosis, a condition where the airway is narrowed due to an underdeveloped cricoid ring. Patients undergoing this procedure are typically already intubated as a result of the airway obstruction caused by the stenosis. The surgical technique begins with a horizontal incision made over the larynx, precisely at the level of the cricothyroid membrane, allowing the surgeon to access the underlying structures. A subplatysmal apron flap is then created and elevated to provide sufficient exposure of the cricoid cartilage. The procedure involves careful dissection to expose the cricoid cartilage and upper trachea by dividing the strap muscles along the midline and retracting them laterally. A vertical incision is made through the lower two-thirds of the thyroid cartilage, the cricoid, and the first two tracheal rings, which effectively relieves the stenosis. After the necessary incisions are made, they are meticulously closed in layers to ensure proper healing. Throughout the entire procedure, the patient remains intubated, and this intubation is typically maintained for approximately 10 days post-operatively to ensure airway stability and support during the recovery phase.
