C-MAC D-Blade vs Macintosh for Postoperative Vocal Cord Evaluation

This study compares two different laryngoscopes-the C-MAC D-Blade videolaryngoscope and the Macintosh direct laryngoscope-for evaluating vocal cord mobility after thyroidectomy. Patients undergo standard anesthesia and intubation with one of the two devices. After surgery, vocal cord function is assessed to identify early postoperative vocal cord impairment. The study aims to determine whether videolaryngoscopy provides a more reliable and less traumatic method for postoperative vocal cord evaluation compared with the traditional Macintosh laryngoscope.
