Official Description

Laryngoplasty, not otherwise specified (eg, for burns, reconstruction after partial laryngectomy)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The procedure of laryngoplasty, as described by CPT® Code 31588, is indicated for various conditions that necessitate surgical intervention on the larynx. These indications include:

  • Burn Injury to the Larynx - This condition may arise from thermal or chemical burns, leading to damage that requires surgical repair to restore function and structure.
  • Reconstruction Following Partial Laryngectomy - Patients who have undergone a partial laryngectomy due to cancer or other diseases may require laryngoplasty to reconstruct the laryngeal anatomy and improve voice quality.
  • Medialization Laryngoplasty for Laryngeal Paralysis - This procedure is performed to treat laryngeal paralysis, where the larynx does not function properly, affecting voice and airway management.

2. Procedure

The laryngoplasty procedure involves several critical steps to ensure effective repair and reconstruction of the larynx. The steps are as follows:

  • Step 1: Incision - A horizontal skin incision is made over the larynx at the level of the cricothyroid membrane. This initial incision is crucial for accessing the laryngeal structures.
  • Step 2: Creation of Flap - A subplatysmal apron flap is created, extending to the level of the thyroid notch. This flap is elevated to provide adequate exposure of the larynx, allowing the surgeon to visualize the area that requires repair.
  • Step 3: Division of Strap Muscles - The strap muscles are divided in the midline and retracted laterally. This step is essential for fully exposing the larynx and facilitating the surgical procedure.
  • Step 4: Laryngeal Tissue Excision - Depending on the specific condition being treated, laryngeal tissue may be excised as needed to remove damaged or diseased tissue.
  • Step 5: Repair of Defect - After excision, a variety of flaps or grafts may be utilized to repair the defect in the laryngeal structure, restoring its integrity and function.
  • Step 6: Drain Placement and Closure - Once the repair is completed, a drain is placed in the neck to prevent fluid accumulation. The overlying soft tissue and skin are then closed in layers to ensure proper healing and minimize scarring.

3. Post-Procedure

Post-procedure care following a laryngoplasty involves monitoring the patient for any complications and ensuring proper healing of the surgical site. Patients may require follow-up visits to assess the integrity of the repair and the functionality of the larynx. It is important to manage any pain and provide instructions for care at the incision site. Additionally, patients may need to avoid certain activities that could strain the larynx during the initial recovery period. The healthcare team will provide specific guidelines tailored to the individual patient's needs to support optimal recovery.
