RADIOLOGICAL STUDY OF THE SKULL BASE DEVELOPMENT / 西安交通大学学报(医学版)

ABSTRACT

The development of the skull base of 1000 cases was studied with skull radiographies. The length of the skull base and cranium were measured and the indexes were calculated. The same measurement and calculation were used to determine the width of the skull base and the cranium. The main results are as follow, The width and length of the skull base are similar in both sexes before 7 years of age, larger in boys than in girls after 7 years and almost never increase at 17 years. Before 14 years, the width of the skull base increases quicker than that of the cranium. Therefore, the indexes are also increased with age, but with no longer increase with age after 14 years. The index of length of the craniumskull base does not increase with age because the development curves of the length of the cranium and skull base are similar.
