The authors present six cases of difficult intubation and review the literature on this subject; The circumstances during which difficult intubation may be feared are recalled; some are due to the morphology of the subject, the others to his previous pathology which may be rheumatological or dermatological. The authors then discuss the method of anaesthesia for this unusual intubation and the various technical means proposed to carry out safely the intubation itself.
