Are you intubated during vocal cord surgery?

Vocal cord polypectomy requires rigid direct laryngoscopy for intubation of the patient and for the procedure itself. The stimulation from direct laryngoscopy often elevates the heart rate and blood pressure of the patient and increases the oxygen demand (MVO2) of the heart.
