Laryngeal mask airway in paediatric otolaryngologic surgery.
The laryngeal mask airway (LMA) is a relatively recent development that fills the gap in airway management between endotracheal intubation and the use of a face mask. The device is inserted blindly into the pharynx, forming a low-pressure seal around the laryngeal inlet permitting gentle positive-pressure ventilation. It allows the administration of inhaled anaesthetic agents through a minimally stimulating airway. This factor, combined with its ease of insertion, suggested that the laryngeal mask airway might offer some distinct advantages in otolaryngologic paediatric surgery. Our experience in utilizing the laryngeal mask in tonsillectomy and adenoidectomy, and in myringotomies with insertion of ventilating tubes is described, and its advantages and disadvantages are discussed.
