[Surgery of cancer of the larynx. The patient in the pre-, per-, and postoperative period].

Surgery of tumours of the larynx requires two main types of operation: -Extensive laryngeal surgery including: -the full pre-operative assessment and preparation of the patient's general condition which is always poor, e.g. due to alcoholism or respiratory failure. -variable techniques, adapted to the lesion, for the control of the patency of the upper airway. -operative risks, such as: reventilation shock, reflex cardiac arrest, disorders of cardiac rythm and gas embolism. -Its complications: -may be immediate and poorly specific, especially respiratory, neurological and infective. -secondary and more specific e.g. Pharyngostoma, and tracheal stenosis. -late complications due to spread of a malignant process. -Laryngeal surgery limited to one vocal cord for which local anaesthetic, improved by neuroleptanalgesia, such as Diethazine-Diparcol, best meets the surgeon and the interest of the patient.
