Basic Info

This video highlights the key points of successful open posterior costochondral laryngoplasty.




posterior costochondral graft laryngoplasty


posterior glottic stenosis;
severe subglottic stenosis;
bilateral vocal cord paralysis


severe active airway inflammation or infection



endoscopic microlaryngoscopy equipment; 90 degree table turn; intraoperative tracheotomy airway

Preoperative Workup

direct laryngoscopy and bronchscopy; rule out severe reflux or eosinophilic esophagitis; rule out active pulmonary disease

Anatomy and Landmarks

anterior larynx split from lower third of thyroid cartilage through the first/second tracheal ring in the midline. The anterior commissure is not divided. The cricothyroid muscles are left intact.
The graft is carved to fit the posterior split with a precise match. The width of the luminal face of the graft can vary from 3-6 mm. It is not necessary to suture the graft into place. After positioning the graft, patients are nasotracheally intubated for 7-10 days in cases of a single-stage approach or a suprastomal stent is positioned for 10-21 days in cases of a double-stage approach.


Advantages: precise positioning of graft. Tracheotomy can be avoided.
Disadvantages: Open approach. Must be careful to not violate the anterior commissure.


Short-term: Graft displacement/migration
Long-term: Arytenoid prolapse/subluxation
