Nase-endoscopic Airway Evaluation for anesthesiologists on anesthesiologists by anesthesiologists 

Nasendoscopy (NES) is an advanced method of airway assessment for patients with known or suspected distortions of airway anatomy.
This technique may be useful before airway management is undertaken. Awake Preoperative Airway Nasendoscopy, which has been used by otolaryngologists for many years to diagnose airway pathology, can also be used for preoperative airway assessment. Endoscopy provides visualization of internal airway anatomy that cannot be viewed with external tests.
