小儿喉的年龄解剖学研究

ANATOMICAL OBSERVATION ON THE LARYNX OF THE CHILDREN

本文对１８０具正常小儿尸体（分为６个年龄组）的喉部位置、形态以及喉、甲状软骨、环状软骨、杓状软骨、喉腔进行了观测．结果为：（１）Ⅰ组喉的位置上下端位于相当第１颈椎与第３、４颈椎体之间，且随着年龄增长而逐渐下移．（２）Ⅰ组喉的形态呈漏斗状．（３）Ⅰ组喉的上下径为２．０９ｃｍ，并随着年龄增长逐渐增大，而Ⅵ组比Ⅰ组长１倍．（４）６个年龄组中形态学变化少．

Six age groups(newborn,51～70,71～90,91～110,111～130,131～150cm,inheight)of 180 normal chinese children cadavers(97 males,83 females )were studied and used andthe larynge,thyroid cartilage,cricoid cartilage,epilottic cartilage,arytenoid cartilage and laryngecavities observed and measured.The main results are as follows:(1)The larynge of the newbornlie in the neck region in front of the first,third and fourth cervical vertebrae.The larynge gradual-ly cut down along with increase in the age. (2)The larynge of the newborn appear funnel-shape.(3)The larynx of the newborn,from the high and to the low,is 2.09 cm.The larynge graduallygrow along with increase in the age.The vertical length in group Ⅵ is twice as long as group I.(4)The shape changes little in the six groups.
