As more information regarding etiologies of dysphagia are obtained, true psychogenic dysphagia is becoming less and less a reality. For example, the entity known as "globus hystericus", when studied more closely can range in etiology from site-specific posterior laryngeal swelling due to acid reflux injury (104) to esophageal motility disorders (52, 53) (104, 121). Therefore, the search for an organic etiology of dysphagia should be exhausted before ascribing a diagnosis of psychogenic dysphagia.
