Computer-assisted anatomical evaluation of the posterior naris in 1 to 3-year-old children
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.
