To compare the incidence differences in the length of the course,the size of nodule and the nature of the lesions of thyroid nodule both on plateau and plain,so to find the incidence characteristics and the method of diagnosis and treatment for the national minority on the plateau.A retrospective analysis was done for totally 308 cases that 157 from plateau and 151 from plain with thyroid nodule.The comparison of difference in the length of the course,the size of nodule and the nature of the lesions in order to analyze the operation mode selection and prognosis of this kind of disease were studied.On the aspect of the length of the course,no statistical difference was found in male both on plateau and plain but statistical difference was found in female that the length of the course was apparently longer on the plateau than on the plain.On the aspect of the nature of the lesions, no statistical difference was found both in male and in female.On the aspect of the size of nodule, there was no linear relationship between the size of nodule and the area both in male and female.And the rate of falling into the chest was no statistical significance;On the aspect of the length of the course,no statistical difference was found in female but was found in male.On the aspect of the nature of the lesions,no statistical difference was found in male(P=0.183)but found in female(χ2=4.176,P=0.041; On the aspect of the size of nodule, there was no linear relationship between the size of nodule and the nationality both in male and female.The course of thyroid nodule was longer on the plateau,mainly was thyroid adenoma and nodular goiter and had lower malignant transformation rate.As that,long course and higher rate of falling into the chest may increase the operation risk.
