A laryngeal mask airway has an airway tube (3) substantially aligned with which there are provided one or two channels (6) containing fibreoptic bundles (7, 8) for emitting and receiving light which is directed into the mask aperture in order to provide a monoscopic or stereoscopic view of the laryngeal anatomy, to facilitate intubation of the trachea while maintaining ventilation of the lungs through the laryngeal mask, or to permit diagnosis or treatment of laryngeal or upper airway pathology. |
