The distribution of nasal types has been reported to be influenced by climatic adaptation as the nose is involved in conditioning inhaled air. Previous studies have reported differential nasal types and dimensions among varying populations which is very beneficial in planning for rhinoplasty and in forensic identification. However, there is inadequate data on nasal types and dimensions of the various ethnic groups in the Ghanaian population. Since it is inappropriate to apply nasal dimensions of one ethnic group to another, the current study sought to assess the nasal types and dimensions of Akans and Ewes in the Ghanaian population. Nasal height, nasal length, nasal tip protrusion, morphological nose width, and anatomical nose width were measured from 202 participants (116 Akans and 86 Ewes) aged 18-27 years belonging to the Akan and Ewe ethnic groups. Nasal index was calculated, and the frequencies of the nasal types among the two ethnic groups were determined. Ewe significantly had greater nasal length and nasal tip protrusion than the Akans. For both ethnic groups, sexual dimorphism was observed in morphological nose width and anatomical nose width, with males having greater values than females. The platyrrhine (broad nose) nasal type was predominant among the Akan and Ewe ethnic groups. The average nasal dimensions of the Akan and Ewe ethnic groups for the Ghanaian population have been reported in the present study, which will be useful in rhinoplasty intended for individuals belonging to these ethnic groups and in identification.
鼻型的分布据报道受到气候适应的影响，因为鼻子参与了吸入空气的调节。先前的研究报告了不同人群之间存在不同的鼻型和尺寸，这对于规划隆鼻术和法医鉴定非常有帮助。然而，加纳人口中各种族群体的鼻型和尺寸的数据不足。由于不适合将一个种族的鼻部尺寸应用于另一个种族，因此目前的研究旨在评估加纳阿坎人和埃维人的鼻型和尺寸。从属于阿坎和埃维两个族群的 202 名年龄在 18-27 岁的参与者（116 名阿坎人和 86 名埃维人）中测量了鼻高、鼻长、鼻尖突出度、形态鼻宽和解剖鼻宽。计算了鼻指数，并确定了两个种族群体中鼻型的频率。埃维人比阿坎人具有更大的鼻长和鼻尖突出度。对于这两个族群，形态鼻宽和解剖鼻宽都存在性别二态性，男性的值大于女性。阿坎人和埃维人族群中以宽鼻（扁鼻）鼻型为主。本研究报告了加纳阿坎和埃维族群的平均鼻尺寸，这对于属于这些族群的个体的隆鼻术和鉴定非常有用。
