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

NCT07277985 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 102

No results posted yet for this study

Summary

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.

Conditions

  • Postoperative Vocal Cord Mobility
  • Recurrent Laryngeal Nerve Injury

Interventions

DEVICE

Videolaryngoscope (C-MAC D-Blade)

The C-MAC D-Blade videolaryngoscope was used to perform endotracheal intubation and to obtain a video-assisted view of the glottis. Its angulated blade design allows indirect visualization, providing improved glottic exposure during intubation and postoperative vocal cord mobility assessment

DEVICE

Direct Laryngoscope (Macintosh)

The Macintosh direct laryngoscope was used for endotracheal intubation with conventional direct visualization of the glottis. This standard laryngoscopic technique was also used for postoperative assessment of vocal cord mobility.
