Answer

Answer

Techniques for assessing vocal fold mobility include indirect and fiberoptic laryngoscopy

Documentation of vocal fold mobility should be a routine part of the preoperative workup

Postoperative visualization should also be performed, as patients may be asymptomatic at first

Laryngeal electromyography (EMG) may be useful to distinguish vocal fold paralysis from injury to the cricoarytenoid joint secondary to intubation, and it may yield prognostic information
