Management of Dysphagia Post-Botulinum Toxin for Cervical Dystonia

Immediate Assessment and Referral

• Refer patients with dysphagia following botulinum toxin injections for cervical dystonia to an experienced speech-language pathologist for instrumental evaluation of swallowing function, specifically videofluoroscopy, to assess the severity and guide targeted dysphagia therapy, as recommended by the American Cancer Society 1, 2, 3
• Assess for warning signs requiring urgent evaluation, such as postprandial cough, unexplained weight loss, or signs of aspiration pneumonia, which mandate immediate speech-language pathology referral, according to the American Cancer Society 1, 2, 3
• Refer to speech-language pathology for videofluoroscopic swallowing study (VFSS) as the first-line diagnostic test, which provides objective assessment of swallowing physiology and identifies specific impairments, as recommended by the American Cancer Society and the Journal of Clinical Oncology 1, 2, 3

Specific Therapeutic Interventions

Swallowing Rehabilitation

• Implement chin tuck against resistance exercises in addition to conventional dysphagia therapy, which targets suprahyoid musculature critical for hyoid/laryngeal movement and has been shown to reduce aspiration, as recommended by the American College of Physicians 4
• Consider respiratory muscle strength training for patients without tracheostomy, as this may decrease aspiration risk by strengthening muscles involved in airway protection, according to the American College of Physicians 4
• Recognize potential psychosocial barriers to swallowing recovery and refer to appropriate clinicians if barriers are identified, as these can impede rehabilitation progress, as recommended by the American Cancer Society and the Journal of Clinical Oncology 1, 2, 3

Monitoring and Follow-Up

• Continue monitoring for GERD, as gastroesophageal reflux can worsen dysphagia and prevent healing of affected tissues, as recommended by the American Cancer Society 5
• Do not delay speech-language pathology referral, as early instrumental evaluation allows for timely intervention to prevent aspiration, malnutrition, and pneumonia, according to the American Cancer Society and the Journal of Clinical Oncology 1, 2, 3
