摘　　要：目的探讨正常甲状旁腺的位置、大小、超声声像图特点及其临床意义。方法选取山西省肿瘤医院2017年1月至12月无相关疾病健康体检者350名,年龄9~83岁,按年龄分为7组,每组50名。回顾性分析受检者超声检查正常甲状旁腺的位置、大小、形状、回声、边界及血流信号特点,比较各组之间的差异。结果350名受检者正常甲状旁腺腺体显示率达95.4%(1335/1400)。正常甲状旁腺为椭圆形、梭状体形或不规则形的高回声或等回声结节,回声均匀,边界清晰,大多腺体内无明显血流信号,其中梭状体形在上甲状旁腺中所占比例(24.4%,161/659)高于下甲状旁腺(18.4%,125/676),二者差异有统计学意义(χ2=6.99,P<0.05)。上甲状旁腺主要位于甲状腺上区,下甲状旁腺主要位于甲状腺下下区尤其是距甲状腺下缘2 cm范围内;在年龄≤20岁组中,上甲状旁腺位于甲状腺上区者所占比例(80.4%,74/92)高于其他年龄组,而其下甲状旁腺位于甲状腺下区者所占比例(30.6%,30/98)高于其他年龄组,差异有统计学意义(χ2=3.35,P<0.05)。不同年龄组之间甲状旁腺大小差异无统计学意义(P>0.05)。结论正常甲状旁腺超声检查显示率高,主要位于甲状腺上区及甲状腺下下区距甲状腺下缘2 cm范围内,声像图以界限清晰的椭圆形、均匀高回声为主。依据超声特点术前对甲状旁腺进行定位,可为甲状腺外科手术中寻找并保留甲状旁腺提供可靠依据。Objective To investigate the location,size,ultrasonic characteristics and clinical significances of normal parathyroid glands.Methods A total of 350 healthy subjects with no relevant diseases in Shanxi Provincial Cancer Hospital from January 2017 to December 2017 were selected.The age ranged from 9 to 83 years old.They were divided into seven groups according to age,with 50 in each group.The position,size,shape,echo,boundary,and blood flow signal characteristics of the normal parathyroid glands in these healthy subjects examined by ultrasound were retrospectively analyzed,and the differences among the different groups were compared.Results The detection rate of normal parathyroid glands in 350 subjects was 95.4%(1335/1400).The normal parathyroid glands were oval,fusiform or irregular shape hyperechoic or isoechoic nodules,with homogeneous echoes and clear borders.There was no obvious blood flow signal in most glands.The proportion of fusiform shape in upper parathyroid glands(24.4%,161/659)was higher than that in lower parathyroid glands(18.4%,125/676),the difference was statistically significant(χ2=6.99,P<0.05).The superior parathyroid gland was mainly located in the superior thyroid region,while the inferior parathyroid gland was mainly located in the inferior thyroid region,especially within the range of 2 cm from the inferior thyroid pole.In the age≤20 years old group,the proportion of patients with upper parathyroid gland in the upper thyroid region(80.4%,74/92)was higher than that in the other age groups,and the proportion of patients with lower parathyroid gland in the subthyroid region(30.6%,30/98)was higher than that in the other age groups,the difference was statistically significant(χ2=3.35,P<0.05).There was no significant difference in the size of parathyroid gland among different age groups(P>0.05).Conclusions The detection rate of normal parathyroid glands is high,and they mainly located in the upper and lower thyroid regions within 2 cm from the lower margin of the thyroid.Ultrasound images are
