We have described what appears to us a most satisfactory anaesthetic technique for microlaryngoscopy and definitive surgery of the larynx. The method of ventilation employed was basically an extension of Sanders' injector technique, using the Venturi principle. Blood gas determinations in aseries of 16 patients showed oxygenation and ventilation to be satisfactory. From the endoscopist's point of view, this technique offered sevral advantages:

1. The endoscopic procedure need not be interrupted to ventilate the patient.

2. Since the patient is adequately oxygenated and ventilated the time for the procedure is not limited.

3. There is no endotracheal tube to interfere with the free access and visualisation of the larynx.
