Which scope is better for checking vocal cords after thyroidectomy?

This study compared two devices—a video laryngoscope (C-MAC D-Blade) and a standard direct laryngoscope (Macintosh)—for checking vocal cord movement after thyroid surgery. 102 patients were randomly assigned to one device during intubation, and their vocal cords were assessed afterward. The goal was to see if the video scope gives a better, less traumatic view of the vocal cords than the traditional method.
