Assessment of vocal cord visibility and function between Video laryngoscope vs Nasal Endoscopy in patients undergoing thyroid surgery

Thyroid surgeries are often associated with potential complications involving the recurrent laryngeal nerve RLN injury making the assessment of vocal cord function an essential component of perioperative care  Accurate and timely identification of vocal cord mobility can significantly influence postoperative management particularly in patients at high risk of nerve injury Recurrent laryngeal nerve  integrity is checked immediately after completion of surgery and after extubation of trachea Most commonly used technique is using Macintosh laryngoscope which is known to cause patient discomfort and hemodynamic instability Other new technique like VL USG LMA C Trach Fiberoptic visualization are supported to be less stressful and reduces patient discomfort The VL provides a magnified view of the glottic structures   and is often easier to use  for practitioners with less fiberoptic experience  On the other hand the FOB remains a gold standard for airway inspection due to its flexibility and close range visualization capabilities although it requires greater expertise and may be more technically challenging when used through an SAD The use of Nasal Endoscopy to visualize the glottic structures immediately after extubation is a novel noninvasive technique of assessing vocal cord function Nasal Endoscopy provides accurate assessment of vocal fold mobility with reasonable patient comfort in the immediate post operative period Comparative studies between these modalities VL vs Nasal Endoscopy are limited particularly in the context of thyroid surgeries where precise assessment of vocal cord function is crucial This study aims Nasal to evaluate and compare the efficacy is of use and diagnostic accuracy of video laryngoscope versus Endoscopy in assessing vocal cords in patients undergoing thyroid surgery
