听神经瘤患者的远红外热像特征分析

摘要

PurposeTo analyze the far infrared thermography characteristics before and after surgery in patients with acoustic neuroma.Materials and Methods Thirty-two patients with acoustic neuroma were included as observation group and 40 normal healthy individuals as control group. Un-cooled thermal imaging system (ATIR-M301B) was used with working temperature of 20-25℃. Craniofacial infrared images were collected to analyze temperature differences among different detection zones.Results Far infrared thermography revealed that there were no obvious temperature differences between both sides of supraorbital region, endocanthion region, frontal region and buccal region in the control group (P>0.05). The temperature differences in bilaterally symmetrical parts of supraorbital region, endocanthion region, frontal region, buccal region were significantly higher in observation group (t=1.557, 1.714, 1.483 and 1.569,P<0.05). The craniofacial temperatures of 32 patients changed after operation, and the differences reduced in supraorbital region, endocanthion region, frontal region, and buccal region (t=2.655, 2.462, 2.897 and 4.465,P<0.05).Conclusion Far-infrared thermography inspection can detect abnormal temperature changes.%目的：分析听神经瘤患者手术前后头面部的远红外热像特征，以探讨其在治疗后的临床应用价值。资料与方法回顾性纳入32例听神经瘤患者作为观察组，并选取40例健康体检者作为对照组。应用ATIR-M301B非制冷焦平面医用远红外热像仪，在环境温度为20~25℃的检查室中，采集两组头面部位远红外热图，比较观察组患者手术前后测温区左右两侧额区、眶上区、内眦区及面颊区的温度差，并与对照组进行比较。结果对照组头面部远红外热像显示额区、眶上区、内眦区及面颊区左、右两侧的温度差异无统计学意义（P>0.05）。观察组额区、眶上区、内眦区及面颊区两侧对称区域温度差值明显大于对照组，差异有统计学意义（t=1.557、1.714、1.483、1.569，P<0.05）；观察组治疗前远红外热像显示患侧呈充血性改变，治疗后显示额区、眶上区、内眦区及面颊区左、右两侧的温度差值减小，差异有统计学意义（t=2.655、2.462、2.897、4.465，P<0.05）。结论远红外热像检查能反映听神经瘤患者头面部相应部位的异常温度变化。
