Although trigeminal neuralgia and atypical facial pain can usually be distinguished on the basis of several well-established criteria, differential diagnosis is difficult in a small number of patients. The purpose of this study was to determine whether the McGill Pain Questionnaire (MPQ) is capable of discriminating between the two syndromes and might therefore serve as a diagnostic aid. The MPQ was administered to 74 patients in Pittsburgh and the data were analyzed statistically in Montreal. In an analysis of the data of 53 patients, 91% of the patients were correctly classified on the basis of 7 descriptors. To determine whether the key descriptors were able to predict the diagnosis of a second group, the discriminant function derived from the first analysis was applied to a new group of 21 patients. A correct prediction was made for 90% of the patients. The results indicate that, in difficult cases, the MPQ may be a useful tool to aid in differential diagnosis.
虽然三叉神经痛和非典型面部疼痛通常可以根据一些既定标准加以区分，但少数患者的鉴别诊断仍很困难。本研究的目的是确定麦吉尔疼痛问卷（MPQ）是否能够区分这两种综合征，从而可能作为一种诊断辅助工具。MPQ被应用于匹兹堡的74名患者，数据在蒙特利尔进行了统计分析。在对53名患者的数据进行分析时，91%的患者基于7个描述符被正确分类。为了确定关键描述符是否能够预测第二组患者的诊断，将首次分析得出的判别函数应用于一组新的21名患者。对90%的患者做出了正确预测。结果表明，在疑难病例中，MPQ可能是有助于鉴别诊断的有用工具。
