Slide laryngotracheopexy for idiopathic subglottic stenosis

Area of Science:

• Otolaryngology
• Thoracic Surgery
• Regenerative Medicine

Background:

• Idiopathic subglottic stenosis (iSGS) is a rare, fibroinflammatory condition causing airway obstruction.
• It is characterized by scar tissue formation in the subglottic and tracheal regions.
• Current treatments can be invasive and may require multiple interventions.

Purpose of the Study:

• To evaluate the long-term outcomes of a novel, single-step surgical technique for iSGS.
• To assess the efficacy of slide laryngotracheopexy using local tracheal grafts.
• To analyze patient-reported outcomes and objective measures post-surgery.

Main Methods:

• Retrospective review of a case series of 13 patients (2 male, 11 female) with iSGS.
• Diagnosis confirmed via endoscopy, CT scans, and autoimmune testing.
• Patients underwent slide laryngotracheopexy and completed post-operative questionnaires (VHI, QoL, MDADI) and spirometry.

Main Results:

• All patients were successfully extubated post-operatively; none required ICU admission.
• Average hospital stay was 14 days; one patient needed temporary tracheotomy due to crusting.
• Post-operative QoL, peak inspiratory flow, MDADI, and VHI scores were favorable, indicating good functional recovery.

Conclusions:

• Slide laryngotracheopexy is a safe and reliable surgical option for Cotton-Myers grade II-IV iSGS.
• The use of tracheal flaps supports optimal mucosal function and airway patency.
• This technique can be beneficial after prior interventions, with adjuvant therapies for granulation tissue considered.
