Nasal&nbsp;index is a useful tool in anthropometry.<br> <strong>Methods:</strong> In this study, nasal parameters of Iranian males and females students were measured&nbsp;(nasal height, nasal width, and nasal index). This study was conducted on 200 medical students&nbsp;of Tehran University, Tehran, Iran. Subjects were 100 males and 100 females, aged 18-30&nbsp;years. The nasal height and width were measured by a sliding vernier calliper and the nasal&nbsp;index was accordingly calculated.<br> <strong>Results:</strong> Our data showed that the mean nasal index for males and females were 68.91&plusmn;8.11&nbsp;and 66.05&plusmn;7.53, respectively. So, nose of Iranian people is leptorrhine type. The mean nasal&nbsp;index in males was significantly (P&le;0.05) higher than that in females.<br> <strong>Conclusion:</strong> The result of this study could be employed in the detection of gender in forensic&nbsp;medicine and rhinoplasty surgery.</p> <p dir="ltr"></p> Nose, Anthropometry, Iran 167 170 http://anatomyjournal.ir/browse.php?a_code=A-10-108-3&slc_lang=en&sid=1 Fatemeh Tahmasebi fatemetahmasebi4@yahoo.com 10031947532846001300 10031947532846001300 No Department of Anatomy, School of Medicine, Tehran University of Medical Sciences, Tehran, Iran.
