Growth of the skull in young children in Baotou, China

Abstract

Background: There are some controversies about the optimal time to perform skull repair in very young Chinese children because of the rapid skull growth in this stage of life. The purpose of this current study is to describe the characteristics of skull growth and to discuss the optimal time for skull repair in young Chinese children with skull defects.

Methods: A total of 112 children born in the First Affiliated Hospital of Baotou Medical College were measured for six consecutive years starting in 2006. Cranial length (CL, linear distance between the eyebrows to the pillow tuberosity), cranial width (CW, double-sided linear distance of connection of external auditory canal), ear over the top line (EOTL), the eyebrows-the posterior tuberosity line (EPTL), and head circumference (HC) were measured to describe the skull growth.

Results: The most rapid period of skull growth occurs during the first year of life. The second and third most rapid periods are the second and third years, respectively. Then, the skull growth slowed and the values of the skull growth index of 6-year-old children were close to those of adults.

Conclusion: Children 0-1 years old should not receive skull repair due to their rapid skull growth. The indexes of children 3 years old or older were close to those of the adult; therefore, 3 years old or older may receive skull repair.
