There can be some confusion with regards to the terminology surrounding laryngoscopy.  The term "video laryngoscopy" can be used imprecisely without specific attention paid to the geometry of the blade containing the video camera.  The geometry of the blade, however, is crucially important as the biomechanics of laryngoscopy differ substantially depending on whether a standard geometry (Macintosh or Miller) blade or a hyperangulated blade is used.  Below you will find specific definition of terms with regards to laryngoscopy and a video demonstrating the differences between direct laryngoscopy, standard geometry video laryngoscopy, and hyperangulated video laryngoscopy.
