OBJECTIVE: Although cricopharyngeal electromyography (CP-EMG) is recognized as a diagnostic tool for dysphagia assessment, few reports in the literature characterize CP-EMG abnormalities in relation to clinical presentation. The aim of this study was to review a large series of CP-EMG studies, and compare the CP-EMG results with the patients' diagnoses. METHODS: A retrospective review of all CP-EMG performed at our institution over a 10-year period was executed. CP-EMG findings were then compared with the patients' clinical history, focusing on potential etiologies of neurogenic injury. RESULTS: Seventy CP-EMGs were reviewed, with 47 (67%) demonstrating neural injury. Of those cases with neural injury on EMG, 29 (60%) had known vagal injuries, 13 (28%) had idiopathic nerve palsies, and 5 (11%) had central etiologies, such as stroke. Each of these three neurogenic subgroups revealed a distinct pattern of EMG abnormalities. CONCLUSION: This study suggests there is an association between patterns of CP-EMG abnormalities and underlying etiology based on clinical history.
