A cross-sectional study of the anthropometry of the face among Bonos and Ewes in the Bono region of Ghana

Abstract

Background: Growth and development of craniofacial structures are of importance since their anthropometry is useful in maxillofacial surgery, plastic surgery, orthodontics and forensic medicine. Surgeons consider the specific facial structures of such patients to help obtain accurate results. Ghana is however less-endowed with data regarding facial anthropometry for the aforementioned applications. Therefore, the study aimed to bring out the differences between the facial measurements of the male and female participants in order to generate baseline data for Ghanaians, taking into consideration the Bonos and Ewes living in the Bono region of Ghana. Twenty-four anthropometric facial measurements were taken from a total of 291 healthy individuals (152 Bonos and 139 Ewes), aged 18–60 years using Shahe Vernier callipers. Results: The study revealed Bono males had significantly longer faces than that of the Bono females (upper face height 2 and total face height). For maxillary height, mandibular width and mouth width, the mean values of Bono males were significantly greater than that of the Ewe males. There was a statistically significant difference concerning nasal length and anatomical nose width among the participants (p < 0.05). Bono male participants had significantly greater values than Ewe males in both endocanthion-exocanthion and endocanthion-endocanthion measurements. Conclusions: The results of this study support the assertion regarding the existence of tribal variations and sexual dimorphism associated with facial measurements and have provided additional data for facial morphology for biometric and forensic applications as well as facial reconstruction especially among the study populations in Ghana.
