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.
