Cricotracheal resection is open airway surgery used to remove a severely narrowed segment involving the subglottis and upper trachea. The operation commonly removes diseased upper trachea together with part of the cricoid cartilage. The remaining healthy airway is then reconnected with a primary anastomosis. The goal is to create a wider, durable airway when less invasive treatments have not provided lasting relief.
read more about cricotracheal resection ...The procedure is used for selected patients with severe or recurrent subglottic or upper tracheal stenosis. Causes can include prior prolonged intubation, tracheostomy, trauma, inflammatory disease, or idiopathic subglottic stenosis. Cricotracheal resection is generally considered when dilation, laser treatment, or other endoscopic procedures fail or are unlikely to provide durable control. The stenosis must be suitable for removal while still permitting a tension-free airway reconstruction.
The surgeon exposes the larynx, cricoid, and upper trachea through a neck incision and precisely identifies the stenotic segment. The diseased airway and selected cricoid tissue are removed while protecting the recurrent laryngeal nerves, esophagus, and lateral blood supply. The healthy distal trachea is brought upward and sutured to the remaining subglottic or laryngeal airway. Release maneuvers and postoperative neck flexion can be used to reduce tension on the new airway connection.
Patients require close airway monitoring after surgery because swelling, bleeding, or problems at the anastomosis can affect breathing. The neck is commonly kept flexed for a period to reduce tension on the repair, and some surgeons use a temporary chin-to-chest reminder suture. Swallowing, voice, breathing, wound healing, and oxygen levels are assessed during recovery. Bronchoscopy or other airway evaluation can be used during follow-up to check healing and detect restenosis.
Possible complications include bleeding, infection, pneumonia, wound problems, airway swelling, and complications related to anesthesia. Anastomotic separation is a serious complication and can cause air leakage, airway instability, or the need for urgent treatment. Injury to the recurrent laryngeal nerves can cause voice or swallowing problems, while scar formation can lead to recurrent stenosis. Some patients require additional airway procedures or a tracheostomy when the reconstruction does not provide a stable airway.
Yes. It is an established open surgical treatment for selected severe or recurrent subglottic stenosis involving the cricoid and upper trachea.
It commonly includes partial resection of the cricoid cartilage together with the stenotic upper tracheal segment. The exact extent depends on the stenosis.
Neck flexion reduces tension on the newly created airway anastomosis. Excessive extension can place stress on the sutured connection during early healing.
Yes. Restenosis can occur from scar formation or healing problems, although the operation is intended to provide durable airway enlargement.
