远红外热像变化可作为针刺治疗急性周围性面瘫的评价指标

Changes of cephalofacial far infrared thermogram as an evaluating index for treatment of acute peripheral facial paralysis

背景：以往实验构建了针刺加远红外热像治疗面瘫,并已证明无论何种证候的面瘫,皆可采用针刺加远红外热像治疗,可明显缩短病程,治愈率高,无任何后遗症。但尚未了解应用远红外热像判断软组织供血状态从而评价病程变化的效果。目的：动态监测急性周围性面瘫患者针刺治疗前后头面部远红外热像的改变。方法：正常对照组为接受健康体检者40例,病例组为临床诊断为急性周围性面瘫的患者40例。应用重庆伟联公司生产ATIR-M301B非制冷焦平面医用远红外热像仪（热敏度为0.05℃）,在环境温度为20-25℃的检查室中,采取头、面部远红外热图。采用本机提供的分析软件,分别比较同一受检者针刺治疗前后头面部左、右两侧面颊、内眦、眶上、额及舌区等5个测温区远红外热像的温度差,并行统计学分析。结果与结论：正常组头面部远红外热像显示面颊、内眦、眶上、额部及舌区5个测温区左、右两侧的温度差异无显著性意义（P〉0.05）。远红外热像可较好地反映急性周围性面瘫患者针刺治疗前后头面部供血状态的变化,针刺治疗前急性期面瘫侧呈充血性改变,患侧面颊、内眦、眶上、额及舌区5个测温区温度明显高于健侧（P〈0.05~0.001）。针刺治疗后头面部远红外热像显示面颊、内眦、眶上、额部及舌区5个测温区左、右两侧的温度无明显差异（P〉0.05）。表明远红外热像可为临床诊断和治疗急性周围性面瘫提供无创的客观评价指标。

BACKGROUND：Previous experiments have demonstrated that acupuncture combined far infrared thermogram could be utilized in treating facial paralysis with short pathogenesis and high cure rate.However,studies underlying using changes of cephalofacial far infrared thermogram as evaluating index for acute peripheral facial paralysis are few. OBJECTIVE：To dynamic monitoring the changes of cephalofacial far infrared thermogram before and after acupuncture therapies in patients with acute peripheral facial paralysis. METHODS：A total of 40 healthy persons were served as the control group,and 40 persons who diagnosed peripheral facial paralysis were included in the case group.Non-refrigerated focal plane thermal imaging system（ATIR-M301B）was used,whose temperature sensitivity was 0.05 ℃ and working temperature was 20-25 ℃.After the checking spots were exposed,cephalic far infrared thermography data were collected and analyzed by software provided by the system.Temperature differences of both sides of cheeks,inner canthi,supraorbitals,forehead and tongue areas were compared with statistical methods in the same patient before and after acupuncture therapies. RESULTS AND CONCLUSION：Far infrared thermography revealed that there were no obvious temperature differences between both sides of the cheeks,inner canthus,sup raorbitals,forehead and tongue areas in the healthy persons（P〉0.05）.Far infrared thermography manifested that obvious temperature differences existed in both sides of the cheeks,inner canthi,sup raorbitals,forehead and tongue areas of patients before acupuncture therapies,and the temperature was higher on affected sides than unaffected ones（P〈0.05-0.001）.Far infrared thermography revealed that there were no obvious temperature differences between both sides of the cheeks,inner canthi,sup raorbitals,forehead and tongue areas after acupuncture therapies（P〉0.05）.Far infrared thermography can be utilized as a visualized index for diagnosis of acute peripheral facial paralysis.
