Objectives To systematically characterize and describe voice and swallowing manifestations in patients with X‐linked dystonia parkinsonism (XDP) and correlate with quality‐of‐life (QOL) measures. Methods Thirty‐four patients with XDP with communication and swallowing difficulties underwent neurological examination, head and neck examination, nasopharyngoscopy, QOL surveys (Swallowing Quality of Life questionnaire [SWAL‐QOL] and Voice Handicap Index [VHI]), and functional endoscopic evaluation of swallowing (FEES) to assess the extent of dysfunction. Results All patients showed high rates of lingual, oromandibular, and laryngeal dysfunction, as well as severe QOL changes in swallowing and communication ability. The most common head and neck manifestations of dystonic symptoms were difficulty coordinating the mouth and tongue (79%), uncontrollable tongue thrusting (53%), and jaw opening (35%). Laryngeal symptoms including vocal strain (adductor voice breaks) or stridor (32%), as well as velopharyngeal insufficiency (20%), were also identified. Of the patients with laryngeal symptoms, 18% had respiratory dystonia. Swallowing assessments showed significant abnormalities in oral bolus control and oropharyngeal dysphagia. FEES examinations showed that 87.5% of the study group had penetration or aspiration. QOL scores showed an average VHI of 94.4 (severe dysfunction), and SWAL‐QOL showed an average of 37.7 (severe dysfunction). Conclusion Swallowing and voice impairment in XDP is not well characterized and presents a more distinctive phenomenology than other neurological disorders, with a unique set of challenges for treatment. This is the first study to systematically evaluate laryngeal and pharyngeal dysfunction in XDP patients and correlate with QOL measures. Level of Evidence 4 Laryngoscope , 130:171–177, 2020
