-
摘要: 目的 研究舌骨体形态的改变,为甲状舌管囊肿的术前诊断及治疗提供参考。方法 采集2016年1月—2021年10月期间经病理确诊的先天性甲状舌管囊肿(甲舌组)以及对照组的CT(正中矢状位)资料,比较两组间舌骨体高度、舌骨体宽度、舌骨体厚度、舌骨体宽度/舌骨体高度、舌骨体厚度/舌骨体高度的差异性。舌骨体高度、舌骨体宽度、舌骨体厚度数据采用t检验;舌骨体宽度/舌骨体高度、舌骨体厚度/舌骨体高度采用Mann-Whitney U检验。结果 甲舌组29例,对照组58例。甲舌组和对照组舌骨体高度分别为(8.93±0.22) mm和(8.94±0.12) mm,两组比较差异无统计学意义(P>0.05);甲舌组和对照组舌骨体宽度分别为(5.09±0.21)mm和(4.48±0.11) mm,舌骨体厚度分别为(3.84±0.12) mm和(3.13±0.08) mm,两组比较均差异有统计学意义(P<0.05);甲舌组和对照组舌骨体宽度/舌骨体高度秩和平均值分别为53.95和39.03,舌骨体厚度/舌骨体高度秩和平均值分别为59.90和36.05,两组比较均差异有统计学意义(P<0.05)。结论 甲状舌管囊肿舌骨体形态的改变有助于术前诊断,舌骨体切除有助于减少术后复发。Abstract: Objective To provide reference for preoperative diagnosis and treatment of thyroglossal duct cyst by studying the morphological changes of hyoid body.Methods The CT data(midsagittal image) of congenital thyroglossal duct cyst(TGDC group) diagnosed by pathology and the control group(C group) were collected from January 2016 to October 2021. The differences of hyoid body height(HBH), hyoid body width(HBW), hyoid bone thickness(HBT), HBW/HBH, HBT/HBH between the two groups were compared. HBH, HBW and HBT were analyzed by t-test; The HBW/HBH and HBT/HBH were analyzed by Mann-Whitney U test.Results Twenty-nine cases were included in the TGDC group and 58 in the C group. The HBH in the TGDC group was(8.93 ±0.22) mm and that in the C group was(8.94±0.12) mm, there was no significant difference between the two groups(P > 0.05). The HBW in the TGDC group and the C group were(5.09±0.21) mm and(4.48±0.11) mm, and the HBT were(3.84±0.12) mm and(3.13±0.08) mm, respectively, the difference between the two groups was statistically significant(P < 0.05). The average rank sum of HBW/HBH in the TGDC group and the C group was 53.95 and 39.03, respectively, and the average rank sum of HBT/HBH was 59.90 and 36.05, respectively, the difference between the two groups was statistically significant(P < 0.05).Conclusion The morphological changes of hyoid body of thyroglossal duct cyst may be helpful for preoperative diagnosis, and it also suggests that hyoid body resection may reduce the possibility of postoperative recurrence.
