INTRODUCTION
The aim of this study was to determine the normal position of the umbilicus so as to offer a guide to improve cosmetic results after the repair of congenital abdominal wall defects.
MATERIALS AND METHODS
The position of the umbilical center was determined in 187 neonates with respect to the xiphoid process, the center of the umbilicus and the pubis. The distance between the xiphoid process and the center of the umbilicus (XU), between the pubis and the center of the umbilicus (PU) and from the xiphoid process to the pubis (XP) were measured while the babies lay in a supine position. The PU:XU ratio was calculated based on these measurements.
RESULTS
Mean XP was 11.93±1.40 cm, mean XU was 7.41±1.08 cm and mean PU was 4.52±0.70 (mean±SD). The PU:XU ratio was calculated as 0.61±0.12 (ratio±SD).
CONCLUSION
We suggest that the PU:XU ratio should be 0.61 offering an ideal localization in umbilical reconstruction.
引言
本研究的目的是确定脐部的正常位置，以便为改善先天性腹壁缺损修复后的美容效果提供指导。
材料与方法
在187例新生儿中，测定脐中心相对于剑突、脐中心和耻骨的位置。在婴儿仰卧位时，测量剑突与脐中心之间的距离（XU）、耻骨与脐中心之间的距离（PU）以及从剑突到耻骨的距离（XP）。根据这些测量值计算PU:XU比值。
结果
平均XP为11.93±1.40厘米，平均XU为7.41±1.08厘米，平均PU为4.52±0.70（平均值±标准差）。PU:XU比值计算为0.61±0.12（比值±标准差）。
结论
我们建议PU:XU比值应为0.61，这在脐部重建中提供了理想的定位。
