Intratracheal Dilation-injection Technique in the Treatment of Granulomatosis with Polyangiitis Patients with Subglottic Stenosis

Abstract

SGS often occurs independently of other features of active GPA. IDIT is a safe and effective technique in the treatment of GPA-related SGS. It should be performed in all patients with GPA who develop significant SGS and in those with multiorgan disease concomitantly with IST. In patients with isolated SGS, IDIT also makes IST and tracheostomy unnecessary.
