目的：探讨以头痛为主诉的鼻窦炎患者，ＥＥＧ、ＢＥＡＭ改变；方法：使用ＥＥＧ～７４１４Ｋ型和ＤＹＤ～３００型ＢＥＡＭ仪。按国际１０～２０系统法放置电极。ＥＥＧ以单、双极导联组合法描绘。ＢＥＡＭ在荧光屏监视下单导连续描记１２０ｓ排除伪差后进行分析处理；结果：ＥＥＧ正常６例，界限性３例，轻度以上异常１４例，异常率为６０％。ＢＥＡＭ正常４例，异常１９例，异常率为８５％；结论：鼻窦炎是临床常见疾病，大多以不同部位头痛为主要症状。易误诊于神经内科。本组病例经头颅ＣＴ扫描排除颅内器质性病变，经Ｘ线诊断采用引流及抗感染治疗而确诊为鼻窦炎，从而提示ＥＥＧ、ＢＥＡＭ亦可见于该病。故在鉴别诊断时应引起重视。
OBJECTIVE: To investigate the changes of EEG and BEAM in patients with sinusitis who are chiefly complained of headache. METHODS: EEG ~ 7414K and DYD ~ 300 BEAM were used. According to international 10 ~ 20 system method to place the electrode. EEG single and bipolar lead combination method. BEAM under the monitor of the screen under single-screen continuous trace 120s to exclude the pseudo-difference analysis; Results: 6 cases of normal EEG, borderline in 3 cases, 14 cases of mild abnormalities, the abnormal rate was 60%. BEAM normal in 4 cases, abnormal 19 cases, the abnormal rate was 85%; Conclusion: sinusitis is a common clinical disease, most of the headache in different parts as the main symptom. Easily misdiagnosed in neurology. This group of patients by skull CT scan exclusion of intracranial organic lesions, the diagnosis by X-ray drainage and anti-infection treatment and diagnosed as sinusitis, suggesting that EEG, BEAM can also be found in the disease. Therefore, differential diagnosis should be taken seriously.
