| 目的：为研究突聋的发病与局部脑血流量(rCBF)的关系以及治疗前后听觉功能变化的机制。方法：应用单光子发射型计算机断层(SPECT)显像, 比较了20例突聋患者治疗前后rCBF摄取计数(RC)和摄取比值(RI).结果：①治疗前患侧RC较健侧有显着性降低, ②治疗后RI较治疗前有显着性增高。结论：①突聋发病与局部脑组织(颞叶)血流灌注量降低有关, ②本项研究治疗有效, 并且治疗后颞叶听觉中枢灌注状态改善与临床听觉功能好转一致。 |

| Purpose:To study the relationship between the cause of sudden deafness(SD) and rCBF,and to detect the mechanism of hearing changes after therapy.Methods:The rCBF regional counts(RC) and regional index(RI) were measured to compare the rCBF changes in the patients with SD before and after treatment.Results:The RC of affected temple was decreased obviously in comparison with the healthy side(P<0001).The RI of post treatment showed a significant increase over pre treatment (P<0001).Conclusions:The cause of SD was interrelated with the decrease of rCBF and the hearing recovery was correlative to rCBF improvement. |
