A novel minimally invasive approach in managing high grade subglottic stenosis

Introduction

A novel minimally invasive approach in managing high grade subglottic stenosis. Discover a novel minimally invasive endoscopic approach for high-grade subglottic stenosis, involving steroid injections, balloon dilatation & stenting. Achieve airway recanalization & preserve voice.

Abstract

Laryngotracheal stenosis is a potentially life-threatening condition. High-grade (Cotton-Myer grade IV) subglottic stenosis (SGS), particularly when adherent to the vocal folds, presents significant technical challenges traditionally managed with open airway reconstructive surgery. We report a single-case technical feasibility study describing a minimally invasive staged endoscopic procedure involving serial intralesional steroid injections (SILSI) to soften mature fibrotic stenosis, followed by a superior–inferior rendezvous technique, balloon dilatation, and temporary stenting. Successful airway recanalization was achieved with preservation of phonatory function. During follow-up, the patient remained clinically stable without evidence of restenosis. This report demonstrates technical feasibility in a carefully selected patient. It is simple and minimally invasive, offering a potential solution for complicated airway stenosis.
