• Inclusion body myositis is an inflammatory myopathy in which dysphagia has been considered a rare finding. However, recent literature finds dysphagia an increasingly common symptom as more cases of inclusion body myositis are identified. Unlike some inflammatory myopathic disorders, inclusion body myositis is resistant to treatment with corticosteroids, and therefore, the otolaryngologist may be consulted regarding surgical options for relief of dysphagia. A patient is described in whom severe progressive dysphagia associated with inclusion body myositis developed. Impaired pharyngeal wall motion and cricopharyngeal achalasia were demonstrated by videofluoroscopic evaluation, and the patient was successfully treated by cricopharyngeal myotomy. The pathophysiologic nature of inclusion body myositis and the mechanisms of cervical dysphagia in the inflammatory myopathies are reviewed. ( Arch Otolaryngol Head Neck Surg. 1992;118:313-317)
