Abstract: Background. Airway management during repair of laryngotracheal stenosis is demanding, and there is currently no accepted standard of care. Recently an increasing number of airway centers have started to use a laryngeal mask until the airway is surgically exposed and cross-table ventilation can be initiated. However detailed data on this approach are missing in the literature. Methods. Patients receiving laryngotracheal surgery from November 2011 until October 2018 were retrospectively included in this single-center study, except for patients who presented with a preexisting tracheostomy at time of surgery. Airway management uniformly consisted of laryngeal mask ventilation until cross-table ventilation was established. Clinical variables, perioperative complications, and airway complications were analyzed. Results. One hundred eight patients (65 women, 43 men) receiving tracheal resection (n = 50), cricotracheal resection (n = 49), or single-stage laryngotracheal reconstruction (n = 9) were included in the analysis. Of the included patients 23 (21.3%) had malignant disease and 85 (78.7%) a benign pathology. In the subgroup of patients with subglottic disease 85.1% had high-grade stenosis (Myer-Cotton III degrees). Airway management with a laryngeal mask was successful in all except 1 patient (99.1%). Mean pulse oximetry and mean end-tidal CO2 during laryngeal mask ventilation was 98.7% +/- 2.4% and 34.8 +/- 7.6 mm Hg, respectively. At the end of surgery 95 patients (88%) were successfully weaned from the respirator using the laryngeal mask. Conclusions. The laryngeal mask as the primary airway device is feasible and safe in patients undergoing laryngotracheal surgery even in cases with high-grade stenosis.
