Definitive surgical treatment for tracheal stenosis, subglottic narrowing, and airway tumours — tracheal resection, cricotracheal resection, laser surgery, and structural reconstruction.
About Airway Surgery
The trachea and subglottis are among the most technically demanding structures to operate on. Narrowing at any level causes stridor, breathlessness, and tracheostomy dependence — conditions that profoundly limit quality of life.
Dr. Narayana manages the full spectrum of airway pathology — from endoscopic laser dilation of early stenosis to complex open tracheal resection with primary anastomosis and cricotracheal reconstruction. The goal in every case is the same: restore a patent, stable airway and achieve decannulation wherever possible.
Surgical Procedures
The gold standard for significant tracheal stenosis and primary tracheal tumours. The narrowed or diseased segment of the trachea is excised and the two ends rejoined directly — restoring a wide, permanent airway without prosthesis or stent.
Up to 50% of the tracheal length (approximately 6 cm) can be resected and anastomosed primarily using neck flexion and laryngeal release manoeuvres to reduce anastomotic tension. Success rates exceed 90% in experienced centres with low restenosis rates.
Used when stenosis involves the subglottis and upper trachea — the most challenging airway segment due to its proximity to the vocal cords and recurrent laryngeal nerves. The cricoid cartilage and narrowed trachea are partially or fully resected and reconstructed with end-to-end thyrotracheal anastomosis.
Cricotracheal resection (CTR) is the definitive treatment for high subglottic stenosis and offers the best long-term results for complex cases that have failed repeated endoscopic dilation. Bilateral recurrent laryngeal nerve preservation is paramount — intraoperative nerve monitoring is used throughout.
CO₂ laser delivered through a rigid bronchoscope or laryngoscope is used to incise and dilate tracheal and subglottic scar tissue. Radial incisions at the stenotic segment followed by balloon dilation provide rapid symptomatic relief without a neck incision.
Laser surgery is most effective for early or mild stenosis (Cotton-Myer Grade I–II), web-like strictures, and as a temporising measure for patients not yet fit for open resection. It is also used for debulking of tracheal papillomas, granulation tissue, and selected benign tracheal tumours. Multiple sessions may be required for recurrent stenosis.
For stenosis where resection and anastomosis is not possible — due to length of the stenotic segment, prior resection, or paediatric anatomy — the narrowed airway is widened using cartilage grafts (costal or auricular) placed anteriorly and/or posteriorly to expand the lumen. A stent or T-tube may be used temporarily to maintain the reconstructed airway during healing.
LTR is the procedure of choice for long-segment stenosis (>3 cm), complex post-radiation strictures, and cases where glottic involvement precludes resection and anastomosis.
Primary tracheal tumours — adenoid cystic carcinoma, squamous cell carcinoma, carcinoid, and others — require complete surgical excision with clear margins followed by primary anastomosis. Secondary involvement of the trachea by thyroid, oesophageal, or laryngeal cancers may also require tracheal sleeve resection as part of a larger en-bloc resection.
Tracheal oncological surgery is one of the rarest and most technically demanding procedures in thoracic and head and neck surgery — requiring both oncological and reconstructive expertise in the same surgeon or team.
Choosing the Right Procedure
Treatment selection depends on the grade, length, and location of stenosis, previous treatments, and whether malignancy is present.
Less than 50% narrowing. First-line: laser dilation ± steroid injection. Many patients achieve long-term control with 1–3 endoscopic sessions. Open surgery reserved for failures.
50–99% narrowing. Laser dilation provides temporary relief but restenosis is common. Definitive surgery — tracheal resection or CTR — discussed at first presentation in fit patients.
Tracheostomy-dependent. Open resection and reconstruction is the only curative option. Careful planning of anastomosis level and tension management is critical.
Poor tissue quality and vascular compromise make both endoscopic and open surgery more challenging. Free-flap augmentation may be needed alongside resection to ensure healing.
What to Expect
Flexible nasolaryngoscopy to assess the subglottis and proximal trachea. CT airway reconstruction to map stenosis length, location, and grade. Pulmonary function tests if indicated.
Examination under anaesthesia with rigid bronchoscope to measure the stenotic segment precisely and assess suitability for resection vs endoscopic treatment.
For resection cases: planning of anastomotic technique, release manoeuvres, ventilation strategy (jet ventilation / cross-field), and intraoperative nerve monitoring setup.
Laser cases: day care to overnight. Tracheal resection or CTR: 3–5 hours under general anaesthesia. Laryngotracheal reconstruction: 4–6 hours. Neck flexion maintained post-operatively with chin-to-chest suture for resection cases.
Chin-to-chest positioning for 7–10 days after resection and anastomosis. Voice rest, humidified oxygen, and nebulised saline. Serial endoscopy to assess anastomosis healing.
Tracheostomy downsized and removed when airway is patent and stable. Voice therapy if vocal cord function affected. Long-term endoscopic surveillance for restenosis.
