[Anatomic study of parietal bone for use as bone graft material].
Anatomic parietal bone structures of 45 adult Chinese cadavers (90 sides) were investigated by measuring the burr holes. The results were as follows. The average thickness of parietal was 5.059 mm and showed an increase with age. In the senile group it was 1.3-1.9 mm thicker than that of the pubertal and middle age. The measurement revealed significant difference in various areas and the posterior and middle parts of the bone was thicker than that of the anterior part. The thickness of diploic layer decreased with age and even disappeared. The above findings may provide a basic data for taking bone graft from parietal bone in clinic.
