Primary Outcome Measures :
  1. Intubation time [ Time Frame: Intraoperative ]
    Time to complete the Intubation in seconds

Secondary Outcome Measures :
  1. Intubation attempts [ Time Frame: Intraoperative ]
    The number of intubation attempts will be recorded (eg 1, 2, 3...)

  2. Esophagal Intubation attempts [ Time Frame: Intraoperative ]
    The number of esophagal intubation attempts will be recorded (eg 1, 2, 3...)

  3. Resistance measurement of the Insertion as assessed by a four point scoring system [ Time Frame: Intraoperative ]

  4. Position of the mask as assessed by the Brimacombe Score [ Time Frame: Intraoperative ]

  5. Pain after Intubation as assessed by a Numeric Rating Scale [ Time Frame: Intraoperative/2h postoperative/24h postoperative ]

  6. AE/Complications [ Time Frame: Intraoperative/postoperative until 24h ]
    Occuring AE/Complications will be recorded
