Malignancy
NO
To compare oropharyngeal leak pressure (OPLP) and ventilatory performance (peak inspiratory pressure, tidal volume, ventilation score) between conventional i-gel and new i-gel PLUS in anesthetized adults, accounting for differences in neck flexion angle.

| Maneuver |
Assign and insert either the supraglottic airway device i-gel or i-gel PLUS.
Set the head and neck angle in the following three stages: neutral position, mild flexion (15 degrees), mild extension (15 degrees)
Measure the angle using a goniometer
