Facial, Nasal, Maxillary, Mandibular and Oro-facial Heights of Adult Ibibios of Nigeria

The study was carried out to determine the mean values of facial, nasal, maxillary, mandibular and oro-facial heights of adult Ibibios. Eight hundred (800) subjects purely of Ibibio ethnic group comprising 400 males and 400 females, aged between 18 and 80 years were used for the study. The facial height, nasal height, maxillary height, mandibular height and oro-facial height were measured using sliding caliper and the results obtained showed that the males had mean facial height of 11.14±0.77cm, nasal height of 4.15±0.34cm, maxillary height of 2.53±0.38cm, mandibular height of 4.46±0.43cm and oro-facial height of 6.99±0.59cm while the females had mean facial height of 10.55±0.74cm, nasal height of 3.93±0.35cm, maxillary height of 2.48±0.49cm, mandibular height of 4.14±0.33cm and oro-facial height of 6.63±0.60cm. Statistical analysis using the z-test showed that the males had significantly higher values than the females in all the facial parameters measured (p<0.05),hence parameters were sexually dimorphic. The data of this study is recommended to forensic scientists, craniofacial surgeons and in anthropological studies
