 After World War I, further advances were made in the field of intratracheal anesthesia.Among these were those made by Sir Ivan Whiteside Magill (1888–1986).Working at the Queen's Hospital for Facial and Jaw Injuries in Sidcup with plastic surgeon Sir Harold Gillies (1882–1960) and anesthetist E. Stanley Rowbotham (1890–1979), Magill developed the technique of awake blind nasotracheal intubation.
