“…There are different anesthesia induction techniques described in the literature for severe stenosis. 12 , 16 Our intraoperative complications were not linked to anesthetic induction, which supports the observation of the previous cohort reported by Krecmerova et al 9 Although our principal anesthetic induction was intravenous (79.07%) with no adverse events reported, it is unclear which technique is best suited for severe stenosis. Another study performed spirometry before and after anesthetic induction in patients undergoing TRR for laryngotracheal stenosis and found that intravenous induction with neuromuscular relaxation, LMA, and positive pressure volume ventilation have better air flows through severe extra thoracic stenosis compared to the spontaneous breathing efforts of the awake patient.…”
