The nasal index has a great value in anthropological studies, because it is one of the anthropometric indices acknowledged in nasal surgery as well as management. Anthropometric studies are very important area for craniofacial surgery and syndromology. The aim of this research was to compare the nasal characteristics between northwestern Nigerian and Iranian populations and compare them with other studies.
The nasal breadths and heights were measured from 400 individuals with 200 participants from Hausa ethnic group of northwestern Nigeria and 200 participants from Northern Tehran, Iran. Nasal index (NI) was calculated and analyzed statistically.
There were significant difference in the nasal breadth ( = 0.0001), height ( = 0.0001) and NI ( = 0.0001) of sex groups in both Iranian and Nigeria population. The distribution of the nasal shapes for Iranian population is 127 leptorrhine (31.9%), 62 mesorrhine (15.6%) and nine platyrrhine (2.3%), while Nigeria population has 120 mesorrhine (30.2%), 75 leptorrhine (18.8%) and five platyrrhine (1.3%). This shows that Nigeria Hausa population has predominantly mesorrhine nose shape, while Northern Iranians are leptorrhine.
The NI of males is higher than females in both population and this study can be of clinical and surgical interest in Rhinology. We recommend further studies to compare the NI of Nigeria and Iranian population of different ethnic groups and with other countries.
鼻指数在人类学研究中具有重要价值，因为它是鼻外科及管理中公认的人体测量指标之一。人体测量研究是颅面外科和综合征学的重要领域。本研究的目的是比较尼日利亚西北部和伊朗人群的鼻部特征，并与其他研究进行比较。
对400名个体进行鼻宽和鼻高测量，其中200名参与者来自尼日利亚西北部的豪萨族，200名参与者来自伊朗德黑兰北部。计算鼻指数（NI）并进行统计学分析。
伊朗和尼日利亚人群中，不同性别组的鼻宽（=0.0001）、鼻高（=0.0001）和NI（=0.0001）均存在显著差异。伊朗人群的鼻型分布为狭鼻型127例（31.9%）、中鼻型62例（15.6%）和阔鼻型9例（2.3%），而尼日利亚人群中中鼻型120例（30.2%）、狭鼻型75例（18.8%）和阔鼻型5例（1.3%）。这表明尼日利亚豪萨人群主要为中鼻型鼻，而伊朗北部人群为狭鼻型。
在这两个人群中，男性的NI均高于女性，本研究对鼻科学的临床和手术具有参考价值。我们建议进一步开展研究，比较尼日利亚和伊朗不同种族人群以及与其他国家人群的NI。
