摘　　要：目的测量1~3岁幼儿鼻后孔的影像解剖数据,为临床鼻后孔疾病的诊断治疗提供相关数据。方法通过CT影像工作站研究240例1~3岁幼儿鼻后孔冠状位CT,观察鼻后孔形态发育,并对鼻后孔测量左右径和上下径及截面积。结果 120例1~2岁幼儿左侧鼻后孔左右径(8.98±0.69)mm,上下径(14.42±1.34)mm,鼻后孔截面积(92.75±14.76)mm^2。右侧鼻后孔左右径(8.93±0.71)mm,上下径(14.25±1.24)mm,鼻后孔截面积(92.31±13.54)mm^2;120例2~3岁幼儿左侧鼻后孔左右径(9.51±0.74)mm,上下径(15.60±1.55)mm,鼻后孔截面积(108.72±18.05)mm^2。右侧鼻后孔左右径(9.54±0.71)mm,上下径(15.76±1.32)mm,鼻后孔截面积(108.66±17.43)mm^2。结论 1~3岁幼儿鼻后孔正常大小可满足幼儿正常呼吸通气量,明显小于此数值则可能造成1~3岁幼儿鼻塞及呼吸困难。Objective To analyze the anatomical and developmental characteristics of the posterior naris in 1 to 3-year-old children, and to provide evidence for the diagnosis and treatment of diseases of theposterior naris in 1 to 3-year-old children. Methods Coronal CT scans of 240 cases（1~3 years old children） were studied with the imaging station. Reference data were identified on these images using imaging station. The sizes of the posterior naris were identified and measured. Results The average of the transverse and vertical diameter for the left side of the posterior naris in 1~2 years old children was （8.98±0.69） mm and （14.42±1.34） mm, respectively. The average of the sectional area for the left side of the posterior naris was （92.75±14.76） mm2. The average of the transverse and vertical diameter for the right side of the posterior naris was （8.93±0.71） mm and （14.25±1.24） mm, respectively. The average of the sectional area for the left side of the posterior naris was （92.31±13.54） mm2. The mean of the transverse and vertical diameter for the right side of the posterior naris in 2~3-year-old children was （9.51±0.74） mmand （15.60±1.55） mm, respectively. The average of the sectional area for the right side of the posterior naris was （108.72±18.05） mm2. The average of the transverse and vertical diameter for the right side of the posterior naris was （9.54±0.71） mm and （15.76±1.32） mm, respectively. The mean of the sectional area for the right side of the posterior naris was （108.66±17.43） mm2. Conclusions The size of posterior naris in 1~3 years old children can meet the normal ventilation volume, and a smaller value may cause nasal obstruction and dyspnea. Chronic stuffy noses and breathing difficulties can affect the intelligence and facial development.
