Successful Assessment of Vocal Cord Palsy Before Tracheal Extubation by Laryngeal Ultrasonography in a Patient After Esophageal Surgery: A Case Report.

Laryngeal ultrasonography has mainly been performed after tracheal extubation. However, improvements in ultrasound technology now allow assessment of vocal cord function even under conditions of endotracheal intubation. We report herein the use of laryngeal ultrasonography in an endotracheally intubated patient after esophagectomy, which allowed us to make the presumptive diagnosis of bilateral recurrent nerve palsy before tracheal extubation. Our experience suggests that laryngeal ultrasonography may be useful in assessing vocal cord function even in endotracheally intubated patients, although the indications and efficacy remain to be determined.
