To identify the normal range and distribution in the cephalic index(CI) and horizontal point of maximum width(H-PMW) of Chinese children with normal brain development.
We retrospectively analyzed Chinese Han children who visited our hospitals between June 2015 and June 2020 because of headache or suspected head injuries. 456 children (257 males, 199 females; aged 0-15 years) were enrolled and divided into 7 groups by age. The values of CI and H-PMW were measured using thin-slice brain computed tomography images.
The overall mean CI was 86.6 ± 5.2. The mean CI for males was 87.0 ± 5.1, and that for females was 86.0 ± 5.2. The overall mean H-PMW was 53.7 ± 2.4. The mean H-PMW for males was 53.8 ± 2.5, and that for females was 53.5 ± 2.3. The averages CI reached the maximum (89.98) at the age of 4-6 months, then began to decrease, decreased to the minimum (84.31) at the age of 2-3 years, and then gradually increased, and reached 86.17 at the age of 8-15 years. The average H-PMW was the smallest (52.17) at the age of 4-6 months, and reached 54.88 at the age of 8-15 years.
The CI and H-PMW values of Chinese normal children reported in this study will provide a valuable reference to diagnose cranial deformities, assess the severity of the disease and the effectiveness of the treatment.
为了确定正常脑发育的中国儿童的头指数（CI）和最大宽度水平点（H-PMW）的正常范围和分布。
我们回顾性分析了 2015 年 6 月至 2020 年 6 月期间因头痛或疑似头部受伤而到我院就诊的汉族儿童。共纳入 456 名儿童（男 257 名，女 199 名；年龄 0-15 岁），并按年龄分为 7 组。使用薄层脑 CT 图像测量 CI 和 H-PMW 值。
总体平均 CI 为 86.6±5.2。男性的平均 CI 为 87.0±5.1，女性为 86.0±5.2。总体平均 H-PMW 为 53.7±2.4。男性的平均 H-PMW 为 53.8±2.5，女性为 53.5±2.3。CI 平均值在 4-6 个月时达到最大值（89.98），然后开始下降，在 2-3 岁时降至最小值（84.31），然后逐渐增加，在 8-15 岁时达到 86.17。H-PMW 平均值在 4-6 个月时最小（52.17），在 8-15 岁时达到 54.88。
本研究报道的中国正常儿童的 CI 和 H-PMW 值将为诊断颅面畸形、评估疾病严重程度和治疗效果提供有价值的参考。
