The Power Of Predictive Model For Age And Sex Using Nasal Parameters

Like languages, facial features have been linked to ethnicities. Basically, nasal index is ratio of nasal breadth to nasal length, which varies greatly among different anthropometric groups and climate regions. Aim: to investigate sexual dimorphic characterization in nasal parameters of the Ikwo population in South-east, Nigeria. Materials and Methods: The study recruited 250 Ikwo samples (males = 130, females = 120), after ethical approval gotten from University Research Committee and informed consents signed by the participants. Nasal length, width and indices were measured. Results: Age and nasal indices appeared positively correlated but with weak R 2 Adjusted value (Age = 146 + 1.91 x Nasal indices, 35%). Also, sex and nasal indices were positive and very strong adjusted level (NI = 61+0.24 x Male and 61 + 0.084 x Female, and 82%). Conclusion: The mean nasal indices for both sexes in Ikwo population belong to platyrrhine nose classification, with predictive power that can be helpful in forensic science, craniofacial surgery, neurosurgery and developmental biology.
