Abstract

This chapter presents information on etiology/pathophysiology, signalment/history, clinical features, differential diagnosis, diagnostics and therapeutics of cricopharyngeal achalasia in cats and dogs. Cricopharyngeal achalasia is a disorder of the cricopharyngeus muscle that causes a relative inability of the proximal esophageal sphincter to relax and compromises the passage of a food or liquid bolus into the esophagus during the pharyngeal phase of swallowing. A complete neurologic examination is important, with particular emphasis on evaluation of the cranial nerves. The neurologic examination is usually unremarkable in patients with cricopharyngeal dysphagia. Differential diagnoses of cricopharyngeal dysphagia include pharyngeal weakness secondary to neuropathies or myopathies, pharyngeal tumors, penetrating foreign bodies, or trauma. Plain cervical and thoracic radiographs are usually unremarkable, but are important to rule out other causes of dysphagia or complications of cricopharyngeal dysphagia.
