During the emergence phase, patients should be extubated either in a deep plane of anaesthesia or fully awake but not in-between. The motor response is via the three main intrinsic laryngeal muscles, the lateral cricoaretenoids, thyroaretenoids (the glottic adductors), and cricoaretenoids (the vocal cord tensors). The need for prolonged or postoperative ventilation must be judged on an individual basis.
