For almost 30 years, nasopharyngeal (NP) EEG electrodes have been used to record epileptogenic discharges in the mesial temporal regions of the brain,^1-3 but are not commonly used in community hospital EEG laboratories. Published studies using this technique included a rather preselected referral patient population.^4-6 This study was conducted in a community hospital EEG laboratory over 18 months. Each of 72 patients having an NP sleep EEG had a recent history suggestive of complex partial seizures. Routine EEG findings were normal or inappropriate for the suspected diagnosis of complex partial seizures. Nasopharyngeal electrodes were placed by a neurologist, using standard insertion techniques.⁷ Sleep was obtained naturally or with chloral hydrate (500 to 1,500 mg). Twelve (16.6%) of the patients had paroxysmal abnormalities. Eight patients (11%) had findings in the NP electrodes; five (6.9%) had paroxysmal discharges only in the NP leads with no diagnosable . . . [Full Text PDF of this Article]
