There is a research paper mentioning voice issues with ES, it’s ‘Management of Dysphagia Pre and Postoperatively In a Case Of Eagle’s Syndrome by Lewis, Hoffman, Spector In 2015’. Also in Fusco, Asteraki, and Spetzler’s (Eagle’s Syndrome Embryology, Anatomy, and Clinical management, 2012) study, they mention vocal changes.
Cranial nerve 10 has been suggested as a nerve which could be compressed or irritated with ES; Motor branches of CN X are responsible for phonation, so compression of this part of the nerve could explain hoarseness or vocal changes.
