NASO-FACIAL ANTHROPOMETRY: A STUDY OF THE CORRELATION BETWEEN
THE NASAL AND FACIAL DIMENSIONS AMONG URHOBOS IN DELTA STATE
UNIVERSITY, NIGERIA.
By *Orie G.A et al. (2 co-authors)
Aim: This study examined the correlation between nasal and facial parameters among Urhobo individuals in Delta State University, Nigeria.
MATERIALS AND METHODS: A descriptive cross-sectional approach was adopted using 300 subjects (149 males and 151 females) aged 18 to 30 years.
Data was collected using standard anthropometric tools, and measurements included nasal height and width, facial height and width, and derived indices.
RESULTS: The results of the present study showed that male facial parameters were higher than those of the female participants. Nasal width (38.61 ± 3.33
mm and 36.47 ± 3.22 mm with p < 0.001), facial width (126.32 ± 9.32 mm and 122.79 ± 7.14 mm, with p< 0.001), and facial height (117.63 ± 8.68 mm and
112.38 ± 9.90 mm, with p< 0.001) for males and females respectively. Nasal index was higher in males (81.30 ± 10.83 and 77.52 ± 11.97, p= 0.004).
Hyperleptoprosopic face (facial index ≥ 100) predominated in both genders (males: 89.26%, females: 88.08%). Mesorrhine nose (nasal index = 70.0–84.9) was
most frequent (males: 53.69%, females: 50.99%). Facial height and nasal height showed a strong positive correlation (r= 0.815, p< 0.001).
CONCLUSION: Sexual dimorphism was observed in most nasal and facial parameters. The predominant face type among males and females was
hyperleptoprosopic, while mesorrhine nose type was most common. Correlation analysis revealed a strong positive relationship between nasal height and
facial height.

PREVALENCE OF PREAURICULAR SINUS AMONG THE URHOBOS IN ABRAKA, DELTA STATE, NIGERIA
By EKPE FO
AIM: This study was carried out to determine the prevalence of preauricular sinus among the Urhobos in Abraka, Delta State,
Nigeria.
MATERIALS AND METHODS : This cross-sectional study considered 384 Urhobo subjects aged 18-65 years, from Abraka, Delta
State, Nigeria. Ethical approval was obtained from the Research and Ethics Committee of the Faculty of Basic Medical Sciences,
Delta State University, Abraka. A questionaire was utilized for the data collection. Data analysis was performed using SPSS
(Statistical Package for the Social Sciences), version 25. Any p-value lesser than 0.05 was considered statistically significant.
RESULTS : The study sample consist of 192 males subjects and 192 female subjects within the age range of 18-65 years and mean
age of 31 years. The prevalence of preauricular sinus is 8.3% in the studied populace. Association of the occurrence of preauricular
sinus between relatives is significant (p= 0.000).
CONCLUSION : Unilateral manifestation of preauricular sinus is more common than bilateral manifestation among the Urhobos in
Abraka, Delta State, Nigeria. The prevalence rate of preauricular sinus is low in the studied populace

Anthropometric Analysis of the Lips of Ndokwa Females in Delta State, Nigeria
By Edike J.O. et al. (1 co-author)
Aim: The aim of this study is to determine selected anthropometric measurements of the lips among Ndokwa females in Delta State, Nigeria.
Materials and Methods: This descriptive cross-sectional study was carried out among 384 Ndokwa females aged 15–24 years from Ndokwa East, Ndokwa West and Ukwuani Local Government Areas of Delta State, Nigeria. Participants were selected using cluster sampling. Data were obtained using a structured questionnaire, while direct anthropometric measurements of the lips and lower third of the face were taken with a digital vernier caliper. The measurements obtained include upper lip height (Sn–Ls), lower lip/chin vertical measurement (Li–Me), intercommissural distance (Ch–Ch), total lip height, upper vermilion height (UVH), lower vermilion height (LVH), and lower facial height (Sn–Me). Data were analysed with the Statistical Package for the Social Sciences and Excel. Descriptive statistics include mean, standard deviation and coefficient of variation.
Results: The mean upper lip height (Sn–Ls) was 12.12 ± 1.57 mm, while the mean lower lip/chin vertical measurement (Li–Me) was 30.28 ± 4.95 mm. The mean intercommissural distance (Ch–Ch) was 42.41 ± 7.74 mm and the mean total lip height was 42.40 ± 5.35 mm. The mean upper and lower vermilion heights were 11.38 ± 1.49 mm and 12.39 ± 1.74 mm, respectively, while the mean lower facial height (Sn–Me) was 55.88 ± 7.66 mm. The intercommissural distance showed the highest coefficient of variation (18.25%), whereas upper lip height recorded the lowest coefficient of variation (12.99%). Differences were also observed in the measured dimensions across the age groups.
Conclusion: This study provides baseline anthropometric data on lip dimensions and related measurements of the lower third of the face among Ndokwa females aged 15–24 years in Delta State, Nigeria. The outcome of this study will serve as guide for anatomical, clinical, aesthetic and forensic experts.

Philtral Column and Nostril Shape Morphology and Their Association among Isoko Adults in Delta State, Nigeria
By Adebisi Adesunloye et al. (1 co-author)
Aim: The goal of this study is to characterise philtral column and nostril shape morphology among Isoko adults in Delta State, Nigeria; and to determine their association and gender-related variation.
Materials and Methods: A descriptive cross-sectional study design was employed, involving 200 healthy male and female Isoko participants aged 18–80 years, selected using cluster sampling. Ethical approval was obtained, and informed consent was secured from all participants. Philtral length and width were measured directly with a digital vernier caliper, while philtral column type and nostril shape were classified from standardised facial photographs. Statistical analysis was performed using the Statistical Package for the Social Sciences, version 25, with significance set at p < 0.05.
Results: The parallel philtral type (38.0%) and the teardrop nostril shape (68.0%) were the most common. A significant association was found between philtral type and nostril shape (p < 0.001), with parallel philtra co-occurring mainly with teardrop nostrils (93.4%) and flat philtra with round nostrils (73.0%). Philtral type was significantly associated with sex (p = 0.032). Males had significantly greater philtral length (15.62 ± 1.95 mm) and width (13.99 ± 1.25 mm) than females (13.61 ± 1.93 mm and 13.21 ± 1.08 mm) with p < 0.001.
Conclusion: The study reveals clear morphological patterns in the philtrum and nostrils of the Isoko population, a strong association between the two features, and notable gender differences in philtral type and dimensions.

Lip Morphometry and Morphologic Pattern Variation Among Ethnic Groups in Delta State, Nigeria
By Ukuedojor J et al. (1 co-author)
Aim: The aim of this study is to determine the lip morphometry and morphologic pattern variation among ethnic groups in Delta State, Nigeria.
Materials and Methods: A multistage sampling technique was employed and a total of 385 people participated in this study; consisting of 128 males and 257 females. The populace are indigenous people from five different ethnic groups namely Urhobo, Anioma, Isoko, Ijaw and Itsekir;i with 77 participants from each ethnic group. With the aid of a digital sliding vernier caliper (validated by calibrating to 0.01mm), the lip measurements were obtained from participants.
Results: Among the participants, the most prevalent lip shape is the full lips (121). Lower lip height (p = 0.001), total lip height (p = 0.000), vermillion height of the lower lip (p = 0.000), and philtrum width (p = 0.000) demonstrated significant ethnic differences. Males and females divulged comparable lip dimensions, with significant variation (p= 0.005) noted in the philtrum width.
Conclusion: The full lips emerged as the dominant morphologic pattern. Significant differences in lower lip height, total lip height, vermilion height of the lower lip, and philtrum width across ethnicities reinforce the need for localized anthropometric data in medical, cosmetic, and forensic disciplines.
