ABSTRACT
Objective To research the thickness of adults frontal bones in many parts and analyze the mean-ing. Methods We chose 130 dry skulls of the Chinese people including 70 male skulls and 60 female skulls and ver-tically devided the frontal bones according the devidement of the superciliary arch into 4 parts on average. Then we measured the thickness of the frontal squama,the frontal tuber,the forehead and temple,the superciliary arch,the or-bital surface and the frontal sinus using the ruler, vernier caliper and protractor. Results We got the thickness of the frontal squama,the frontal tuber,the forehead and temple,the superciliary arch,the orbital surface and the frontal si-nus and calculated the average datas. What's more,besides the thickness of the frontal tuber,forehead and temple,the superciliary arch had statistical significance(P < 0.05) between males and females, other parts of the frontal bones had no statistical significance(P>0. 05). Conclusion We measured the thickness of the frontal squama,the frontal tu-ber,the forehead and temple,the superciliary arch,the orbital surface and the frontal sinus and the datas will had good guiding roles to our department's work.
