Vocal Cord Dysfunction - Article
ABSTRACT: Vocal cord dysfunction involves inappropriate vocal cord motion that produces partial airway obstruction. Patients may present with respiratory distress that is often mistakenly diagnosed as asthma. Exercise, psychological conditions, airborne irritants, rhinosinusitis, gastroesophageal reflux disease, or use of certain medications may trigger vocal cord dysfunction. The differential diagnosis includes asthma, angioedema, vocal cord tumors, and vocal cord paralysis. Pulmonary function testing with a flow-volume loop and flexible laryngoscopy are valuable diagnostic tests for confirming vocal cord dysfunction. Treatment of acute episodes includes reassurance, breathing instruction, and use of a helium and oxygen mixture (heliox). Long-term management strategies include treatment for symptom triggers and speech therapy.
ABSTRACT: Swallowing disorders are common, especially in the elderly, and may cause dehydration, weight loss, aspiration pneumonia and airway obstruction. These disorders may affect the oral preparatory, oral propulsive, pharyngeal and/or esophageal phases of swallowing. Impaired swallowing, or dysphagia, may occur because of a wide variety of structural or functional conditions, including stroke, cancer, neurologic disease and gastroesophageal reflux disease. A thorough history and a careful physical examination are important in the diagnosis and treatment of swallowing disorders. The physical examination should include the neck, mouth, oropharynx and larynx, and a neurologic examination should also be performed. Supplemental studies are usually required. A videofluorographic swallowing study is particularly useful for identifying the pathophysiology of a swallowing disorder and for empirically testing therapeutic and compensatory techniques. Manometry and endoscopy may also be necessary. Disorders of oral and pharyngeal swallowing are usually amenable to rehabilitative measures, which may include dietary modification and training in specific swallowing techniques. Surgery is rarely indicated. In patients with severe disorders, it may be necessary to bypass the oral cavity and pharynx entirely and provide enteral or parenteral nutrition.
