Details and patient eligibility

About

Suspension laryngoscopy is realised during apnea. In effect, surgeons are in the mouth of the patient and we can't have access at the aiways.

So investigators like to use a Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) to increase time of apnea and decrease the impact of oxygen desaturation.
