    Nasal anthropometry can be employed in identification of the race and sex of individuals whose identity is unknown. The sample comprised 420 subjects aged 18-65 years; comprising 210 males and 210 females across the Okun Ethnic group in Kogi State, Nigeria. The main purpose is to provide anthropometric data on the basic nasal parameters (nasal height, nasal width and nasal index) for Okun ethnic group of Kogi State Nigeria. Total body height and Nasal height were recorded with stadiometer and digital Vernier caliper respectively. Nasal index (NI) was calculated as NB/NH×100. The statistical package for social sciences (SPSS) version 23.0, Student's t-test comparison were used to determine group differences. Pearson's correlation and regression analysis were used to analyze the data. P < 0.05 was considered significant. The mean of total body height in the male and female was 169.10 (±7.69) cm and 166.8 (+7.81) cm respectively. The mean of nasal index in the male and female was 98.43 (±8.87) mm and 97.19 (±7.85) mm respectively. In this study, it was observed that nasal index and stature were higher in males than females, hence a significant level of sexual dimorphism. The result showed that platyrrhine nasal type was predominant among the Okun ethnic group. This study provides baseline data for quantitative description of nasal morphology in people of Okun ethnic group. This will be valuable as a nasal anthropometric tool for clinical practice, in reconstructive surgery, rhinoplasty, and in forensic science.

    Craniofacial genetics as a differential identification tool: analysis of a subset of Yoruba-speaking population in Nigeria
    (Egyptian Journal of Medical Human Genetics, 2025) Suwebat Bidemi Kareem,; Olugbenga Akinola,; Oluyinka Ajibola Iyiola,; Misturah Yetunde Adana,; Ade Stephen Alabi,; Aminu Imam,; Moyosore Salihu Ajao,
    Background Population-dependent genetics and normal-range variations in facial morphology have been reported across several populations, but there is paucity of literature on the African population. The study was designed to evaluate the potentials of craniofacial genetics as a differential identification tool amongst the Yoruba-Ethnic nationality in Nigeria. An anthropometric study of two thousand one hundred and nine (2109) randomly selected individuals (age 15–29 years) was conducted. The personal information of participants was obtained using semi-structured, self-administered questionnaires, while craniofacial parameters were measured from facial photographs with Digimizer software. DNA was isolated from buccal swabs samples obtained from three hundred participants (300) after careful stratifications to match the chosen ethic group. Segments of two craniofacial-associated genetic markers (PAX3 and BMP4 genes) were amplified from participant’s DNA samples using polymerase chain reaction technique. The amplified gene segments were purified, sequenced, and aligned with the reference sequences from the NCBI database. Results A total of 45 samples were observed with synonymous and non-synonymous changes across the 2 genes. These genetic changes were not significantly associated with craniofacial differences in the study population. However, two participants, one each for PAX3 and BMP4, displayed higher polymorphisms that were associated with values of different craniofacial linear parameters {Nasal width (al–al), Nasal height (n-sn), Morphological facial height (n-gn), Bizygomatic distance (zy–zy), Interendocanthal width (en–en), Ear width (t-pa), Ear height (sa-sba), Mandible height (sto-gn), Mouth width (ch–ch), Vermillion height (ls-sto), Eye fissure width@ R(en-ex)}, different from the general population not statistically significant. Conclusion The slight differences in craniofacial parameter measurements in two individuals, with novel polymorphisms (SNPs) loci in PAX3 and BMP4 provides insights to baseline data for validation of cranio-genetic markers that may be useful in the population under study

    Morphometric Analysis of Mandibular Foramina in Adult Nigerian Mandible
    (Era’s Journal of Medical Research, 2025-08-29) Suwebat Bidemi Kareem,; Ajiboye Adefikayo Adebisi,; Olugbenga Olawale Eweoya,; Aminu Imam,; Misturah Yetunde Adana,; Moyosore Salihu Ajao
    Background and Objective: The mental neurovascular bundle emerges at the mandibular foramina (MF) a significant anatomical landmark on the anterolateral part of the jaw. Its morphological features, and precise location have important clinical implications for dental anesthesia, implant placement, and surgical procedures of the lower jaw. Population-dependent variations in the MF characteristics, however, are very common, and studies on Nigerian mandibles have been remarkably sparse. The present study was undertaken to provide crude morphometric data on the incidence, location, size, and accessory foramina of the MF in a Nigerian sample population. Materials and Methods: The study entailed the analysis of sixty adult human mandibles (36 males and 24 females) stored in the Department of Anatomy, University of Ilorin. All specimens were complete and free of any deformity. Measurements were collected using a calibrated Vernier caliper, in a nominally modified version of the method of Alma et al. The positional relationship with the adjacent teeth was considered, and the occurrence of accessory mental foramina (AMF) was noted. Data were statistically processed using SPSS version 21.0, and it facilitated the generation of descriptive statistics. Results: Bilateral MF were found in all mandibles studied. Circular patterns were more common than oval ones, appearing in 58.33% of cases on the left and 66.67% of cases on the right. With 48.33% on the right and 58.33% on the left, the foramen was most frequently observed in connection with the second premolar tooth. On average, the transverse size was 4.19 ± 1.18 mm on the left and 3.98 ± 1.17 mm on the right, while the vertical dimension was 3.06 ± 0.80 mm on the right and 3.19 ± 0.92 mm on the left. 8.33% of the left sides, and 11.67% of the right sides had accessory foramina. Conclusion: The present findings support that the MF in Nigerian mandibles is predominantly circular and most frequently found at the level of the second premolar. The presence of accessory foramina in some specimens highlights the necessity for careful preoperative evaluation. These anatomical structures are not only important for dental, and maxillofacial surgeons, but also carry immense anthropological and forensic significance.
