Comparative Treatment Outcomes for Idiopathic Subglottic Stenosis: 5-Year Update

William S Tierney et al. Otolaryngol Head Neck Surg. 2023 Jun.

Abstract

The North American Airway Collaborative (NoAAC) previously published a 3-year multi-institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating treatment effectiveness. Patients in the NoAAC cohort were re-enrolled for 2 additional years and followed using the prespecified published protocol. Consistent with prior data, prospective observation of 487 iSGS patients for 5 years showed treatment effectiveness differed by modality. Cricotracheal resection maintained the lowest rate of recurrent operation (5%), followed by endoscopic resection with adjuvant medical therapy (30%) and endoscopic dilation (50%). These data support the initial observations and continue to provide value to providers and patients navigating longitudinal decision-making. Level of evidence: 2-prospective cohort study.

Keywords: cricotracheal; dilation; dyspnea; endoscopic resection; iSGS; idiopathic; laryngology; subglottic stenosis; tracheal resection.
