    Anthropometric Evaluation of Nasal Height, Nasal Breadth and Nasal Index among Bini Children in Southern Nigeria
    (2019) Omotoso, Dayo
    Background and Objective: The nasal dimensions are important cephalometric parameters used in physical anthropometry to distinguish different gender and groups of human population. It also used to categorize the human nasal morphology into five different morphological categories which include hyperleptorrhine, leptorrhine, mesorrhine, platyrrhine and hyperplatyrrhine. In this anthropometric study, the nasal morphological characteristics of the Bini children in Nigeria were evaluated and the prevalent nasal morphology of the study population determined. Methodology: This study involved randomly selected 500 Bini children (comprising 250 males and 250 females) between ages 5-12 years. The nasal dimensions of each subject were measured between relevant anatomical landmarks. These include the nasal height measured as distance between nasion and subnasale and the nasal breadth measured as distance between the most lateral points of right and left ala of the nose using a sliding caliper. The nasal index for each subject was calculated as nasal breadth divided by nasal height and expressed as percentage. Results: The mean nasal height for male and female Bini children was 4.58± 0.11 and 4.33 ± 0.10 while the mean nasal breadth was 4.05 ± 0.12 and 3.88 ± 0.11 respectively. The mean nasal index for male subjects (90.25 ± 1.33) was also higher than for female subjects (88.65 ± 1.50). The morphological classification showed the platyrrhine nose type as the most prevalent among the male (70.0%) and female (68.0%) Bini children. Conclusion: The nasal dimensions and nasal index demonstrated prominent sexual dimorphism and the dominance of platyrrhine nose type is the current trend in the nasal morphology of Bini children.

    Morphometric Study of Cephalo-Facial Indices among Bini Children in Southern Nigeria
    (2019) Omotoso, Dayo
    Cephalometry is an important branch of anthropometry which involves the morphological study of structures present in the human head or scientific measurement of the dimensions of the head. Some of the most important cephalometric parameters include the length/height and breadth/width of the head, the face and the nose as well as their respective indices. These cephalometric parameters are vital in the description of variation which is a common phenomenon that characterizes human physiognomy. They are also useful in the description of human inter-racial and intra-racial similarities both within and across gender. This study involved 450 Bini children (235 males and 215 females) between ages 5-12 years. The length and width of the head and face of each subject was measured between the appropriate anatomical landmarks using spreading and sliding calipers. The measurements were used to calculate the cephalic and facial indices for each subject. The result showed sexual variation in both cephalic and facial indices among the Bini children with the males having higher values than the females. Also, the result of this study showed that prevalence of brachycephalic head type among both male (51.1%) and female (49.8%) Bini children. The mesoproscopic face type was the most prevalent face type among both male (62.6%) and female (47.4%) Bini children. The cephalo-facial indices are vital in demonstrating similarity and variation in physical morphologies of individuals or group of people of different ethnicity, races, gender and geographical locations.
