RESUMEN
Objective To deal with measurements of the relative convexity, to observe the morphological characteristics of zygoma and zygomatic arch, and to provide references for anthropology and medical science. Methods 108 dry skulls (62 male and 46 female) from Wuhan University Medical School were used, the zygomatic relative convexity of both sides were measured, and the morphological characteristics were observed in this study. Results Zygomatic process point lied in the middle of zygoma in horizontal direction, and situated 15-20 mm below the external middle 1/3 of infra-orbital margin. The zygomatic arch was anterolateral convexity, and face width in male was bigger than that in female. Conclusion The relative convexity and morphological characteristics of zygoma and zygomatic arch provide
