【摘要】：目的研究正常人颌下腺的多层螺旋CT(MSCT)影像解剖,探讨不同年龄组颌下腺位置的增龄性改变以及性别间差异。方法回顾性分析220例行常规头颈部MSCT检查、无颌下腺疾病患者的影像资料,按照年龄及性别分组,采用多平面重组(MPR)技术,测量并计算两侧颌下腺至下颌骨的平均距离以及两侧颌下腺内缘间距、外缘间距。运用SPSS 17.0统计软件行统计学分析。结果腺-颌间距、腺体内缘间距与年龄具有相关性(P=0.000,P=0.000),均随年龄增长而增大。除中年组与老年组腺-颌间距差异无统计学意义外,余各年龄组间腺-颌间距差异均有统计学意义;腺体内缘间距两两比较显示未成年组、青年组与中年组、老年组间差异有统计学意义。男性的腺-颌间距,腺体内缘,腺体外缘间距均大于女性(P=0.000,P=0.000,P=0.000)。结论 MSCT可有效评价正常颌下腺腺-颌间距与腺体内外缘间距及其增龄性改变,所得数据可作为颌下腺临床与老龄化研究的参考依据。
[Abstract]:Aim to study the multi-slice spiral CT (MSCT) imaging anatomy of submandibular gland in normal subjects, and to explore the age-related changes of submandibular gland location in different age groups and the difference between sexes. Methods the imaging data of 220 patients with normal head and neck MSCT and submandibular gland disease were analyzed retrospectively. The patients were divided into groups according to age and sex. Multi-plane recombinant (MPR) technique was used. The mean distance from the bilateral submandibular gland to the mandible, the distance between the inner margin and the outer margin of the submandibular gland were measured and calculated. SPSS 17.0 statistical software was used for statistical analysis. Results the distance between the gland and the jaw and the distance between the inner margin of the gland were correlated with the age (P < 0. 00, P < 0. 000), and increased with the increase of the age. There was no significant difference in gland-jaw spacing between the middle-aged group and the elderly group except for the middle-aged group and the elderly group. There was significant difference in the gland-jaw spacing among the other age groups. A pairwise comparison of the inner margin of the gland showed that there was a significant difference between the immature group, the young group, the middle-aged group and the elderly group. The distance between the gland and the jaw, the inner margin and the outer margin of the gland were larger in the male than in the female (P < 0. 00, P < 0. 000, P < 0. 000). Conclusion MSCT can effectively evaluate the distance between the normal submandibular gland and the outer margin of the gland and the aging change. The data obtained can be used as a reference for the clinical and aging studies of the submandibular gland. [WT5HZ] [WT5 "HZ] conclusion [WT5" BZ]
