Objectives: We hypothesize that the laryngeal mask airway (LMA) is a safe technique for airway management in pediatric adenotonsillectomy (T&A). Methods: After institutional review board (I.R.B.) approval, we conducted a retrospective review of 1199 medical records of children who underwent T&A from 2002 to 2006 at Doernbecher Children's Hospital, a teaching institution in Portland, OR. There were no significant demographic differences between the LMA (n=451), endotracheal tube (ETT) (n=715), and failed LMA groups (n=33). Outcome variables were LMA failure (LMA replaced with endotracheal tube), and any complication. We collected demographic and medical data to determine the incidence and predictors of LMA failure, and to characterize the failed LMA group. Results: The incidence of LMA failure was 6.8%. Patients who underwent adenoidectomy had significantly lower odds of LMA failure compared to patients who had a tonsillectomy or adenotonsillectomy (OR 0.28, 95% CI 0.15-0.52, P
