摘要
目的 :了解第 1至第 6气管环的形态结构特点。方法 :对 40具正常成人尸体第 1气管环至第 6气管环的结构进行了详细的观察测量。结果 :发现第 1至第 5气管环的内横径、内矢状径平均值逐渐增大 ,分别为 16 .0～ 17.1mm和 13 .5～ 14 .2mm。而第 5、第 6气管环的内横径 ,内矢状径是基本相等的 ,分别为 17.1mm和 14 .2mm。结论 :对于全喉切除术后进行发音重建 ,防止气管瘘口狭窄和研究发音机制均有重要的临床意义。
To observe and measure the morphological features of the cervical trachea ring.Methods:The structures of the first to sixth trachea ring were observed and measured on 40 normal cadavers (male 30 and female 10).Results:The intenal transverse diameter and sagittal diameter from the first to fifth trachea ring was found to become bigger gradually and aranged from 16.0 mm to 17.1 mm and from 13.5 mm to 14.2 mm respectively.However,the internal transverse and sagittal diameter of the sixth trachea was equal to that of fifth,17.1 mm and 14.2 mm separately.Conclusion:These data should benefit the voice restoration of post-laryngectomy and prevention the narrow of trachea orifices and studying the voice mechanism.
