Retromolar Vocal Cord Visualisation
For easier insertion of the laryngoscope the head of the patient will be turned to the left site. Thereafter the blade (Miller) will be inserted into the mouth and pushed carefully as far as possible laterally to receive a direct view of the vocal cords. Then the performing anesthesiologist determine the Cormack \& Lehane score without and thereafter with a BURP (backward upward rightward pressure) maneuver.
Conventional Vocal Cord Visualisation
The head of the patient will be positioned as usual. After 2 minutes oxygen insufflation the laryngoscope will be inserted laterally to push the tongue to the left side in order to release the sight to the vocal cords. Thereafter the anesthesiologist determines the Cormack \& Lehane score without and thereafter with performance of the BURP (backward upward rightward pressure) maneuver.
