title: Orotracheal intubation through the laryngeal mask airway in paediatric patients with Treacher-Collins syndrome.
abstract: The laryngeal mask airway (LMA) is useful as an airway intubator (conduit) for an intubating tracheal bougie or fibreoptic bronchoscope, over which a tracheal tube is passed. However, in our paediatric patients with Treacher-Collins syndrome, only the latter technique was successful. This was attributed to the fact that a posteriorly protruded tongue displaced the LMA, made the glottis move considerably anterior and interfered with the attempts to enter the trachea with a bougie. Downward displacement of the epiglottis, which can sometimes impair the intubation technique through the LMA, was not observed in our patients. Partial obstruction of a tracheal tube within the LMA occurred in one of the patients.
