Conventional techniques of laryngoscopy for vocal cord palsy can sometimes be difficult or impossible to perform, and B-mode real-time ultrasonography has been previously reported by the authors to be helpful in these situations. In some cases, however, B-mode ultrasonography can be inconclusive. We investigated whether color Doppler imaging can significantly improve vocal cord examination in these cases. ⋯ Color Doppler imaging for vocal cord examination is more sensitive than B-mode real-time ultrasonography, and seems to be as accurate as laryngoscopy in determining vocal cord palsy or paresis.
