Analysis of Hemorheology Index of Sudden Deafness

Purpose To observe the changes in hemorheology in sudden deafness and to elucidate the signifi- cance of microcirculatory impairment in the etiology of the disease.Methods Seventy-six cases with sudden deafness and 168 normal cases as control group were included in this study.All the cases in the two groups were respectively divided into male and female;old-,middle-and young-aged subgroups.Examination of hemorheology was performed and the in- dexes were compared between the corresponding subgroups.Results There were significant elevation of blood viscosity (high,middle shearate),blood plasma viscosity and hematocrit of the old-aged deafness sudden deafness group,blood plasma viscosity of the middle-aged group,and blood viscosity of the female deafness group(high shearate)compared with the corresponding control group.Conclusion The etiology of the old aged sudden deafness(especially the females) is connected with microcirculation impairment.(Chin J Ophthalmol and Otorhinolaryngol,2007,7:238-239)
