 A 56-year-old male with Kennedy-Alter-Sung syndrome(KAS)was referred to our outpatient clinic because of progressive breathy hoarseness and dysphagia for two years. Laryngoscopic finding demonstrated hemi-lateral vocal fold palsy on the right side without movement disorder of the vocal fold on the left side. There were no abnormal findings to cause vocal fold palsy on the right side on brain MRI,neck and chest CT. However,electrographic study revealed that bilateral crico-arytenoid and crico-thyroid muscles showed neurogenic change during phonatory movement. And the degree of the neurogenic change of these muscles on the right side was stronger than that on the left side. From these findings,we diagnosed that hemi-lateral vocal fold palsy on the right side of this patient was induced by KAS.
