Vocal Cord Movement Assessment Using Airway Ultrasound.
- Conditions
- Vocal Cord Movement Assessment by Airway Ultrasound
- Interventions
- Device: airway ultrasound for vocal cords movement assessment.
- Registration Number
- NCT02847819
- Lead Sponsor
- Rajiv Gandhi Cancer Institute & Research Center, India
- Brief Summary
Total of 100 patients are included in this is a prospective observational study to evaluate the role of airway ultrasound (USG) in assessing vocal cord mobility in patients undergoing thyroid surgery. patients will be scanned preoperatively by airway ultrasound which will be compared to post operative ultrasound scans.
- Detailed Description
All 100 patients between age groups of 15-70 years, will be scanned pre-operatively to see vocal cord mobility as a reference value. A proper acoustic window is mandatory for optimal visualization of laryngeal structures. Visibility of false vocal cords, true vocal cords and arytenoids will be given one point each for one side, maximal score will be 6. According to points the acoustic window scoring for glottis aperture will be graded as fair, when both false vocal cords are visible (score1-2), along with false cord when both arytenoids are visible scored good (score3-4) and if single or both true vocal cords are visible then scored as very good(score5-6). After the surgery the same patient will be scanned again for vocal cord mobility at 4hours of extubation . Any change in mobility will be recorded. If any change will be observed, direct laryngoscopy (DL) will be done to confirm the diagnosis. Any complication in the post-operative period will be recorded.

Group Intervention Description Vocal cords movement assessment by airway USG. airway ultrasound for vocal cords movement assessment. Preoperatively patients undergoing thyroid surgery will be scanned by airway ultrasound and graded for vocal cord movement, the same group of patients will be again scanned and graded by airway ultrasound at 4th post operative hours.
- Primary Outcome Measures
Name Time Method Objective confirmation of vocal cords movement pre operatively and at 4 hours after extubation
- Secondary Outcome Measures
Name Time Method Comparison of preoperative doppler velocity with post operative doppler velocity. At 4 hours after extubation.
