Glottis Visualization in Different Lifting Methods

Among the various types of video laryngoscopes, the McGrath MAC video laryngoscopy (VL) has become popular because it is lightweight and can be quickly and hygienically prepared by changing the blade. The aim of this study was to compare the efficacy of two different methods (direct and indirect) for epiglottis removal during visualization of the glottis using the McGrath MAC VL.
