(A) Transnasal fiberoptic laryngoscopy conducted 2 months prior to surgery shows right vocal cord palsy. (B) No abnormal adduction of the vocal fold occurred during inspiration on transnasal fiberoptic laryngoscopy after removing continuous positive airway pressure.

Transnasal fiberoptic laryngoscopy taken 2 months prior to the surgery showed right vocal cord palsy (Fig. 1A). No left vocal fold adduction movement was detected on inspiration during transnasal fiberoptic laryngoscopy (Fig. 1B).
Continuous positive airway pressure of 5 cmH2O was applied to the patient via face mask in the post-anesthesia care unit.
