We present the case of an adult patient with a malignant goiter, treated in our center, where airway management is performed by an awake intubation technique with sedation. The patient, with great compromise and deviation from the midline of the airway, was managed with a High-Flow Nasal Cannula (CNAF) during its manipulation, helping to avoid desaturation events during the intubation procedure, associated with the administration of monitored sedation.
