ABSTRACT

Background/Objective: The quality of inhaled air may depend on the shape of the nose and may vary from one ethnic group to another. The aim of this study was to compare nasal anthropometry between Bini and Igbo ethnic groups of Nigeria. Materials and Method: A total of 800 subjects (400 from each ethnic group) were recruited for this study. The parameters assessed include nose length, nose width, nasal protrusion, alar thickness, columellar thickness and nares diameter, nose width-length index (nasal index), nasal protrusion-width index and nasal protrusion-length index. Results: The results showed that the most prevalent nose types among the Binis were mesorrhine and platyrrhine noses with no statistically significant difference between them while platyrrhine was the most prevalent nose type among the Igbos. Among the females, nose length, nasal protrusion, nasal protrusion-width index, alar thickness and nares diameter were significantly higher among the Binis than Igbos while nose width-length index and nasal protrusion-length index were significantly higher among the Igbos than Binis. Among the males, nose length, nasal protrusion, nasal protrusion-width index and nares diameter were significantly higher among the Binis than Igbos while nose width-length index was significantly higher among the Igbos than Binis. Conclusion: This study showed that nose length, nasal protrusion, nasal protrusion-width index and nares diameter are higher among Binis than Igbos while nasal index is higher among the Igbos than Binis. This reflects the striking appearance of the noses of Binis. This study may be useful in drawing forensic comparison between Binis and Igbos.
