Nose and Nasal Architecture: An ethnic variations
Keywords:Nasal Architecture, Ethnic variation, Photographic evaluation
Objective: The objective of the study undertaken was to evaluate if geometric and mathematical relationship of Nose and Nasal Architecture of female population of three ethnic groups of Nepal . Methods: Sample consisted total of 135 Nepalese females in age group of 18-25 years belonging to three ethnic groups of Nepal . Each group comprised of 45 females. For the study extra oral facial photographs were obtained in Frontal View, Profile View ,Sub MentoVertex View (Basal View). Evaluations were done using the Goode Method and Fomans Method Results: Nasal Projection in tarai region females had maximum projection of the nose (61% ± 8) followed by Hilly females (60% ± 5.50) and least projection of nose was found in mountainous region females (50% ± 7). Nasal Projection showed no significant difference in hilly and tarai Nepalese females but shows significant difference between hilly and mountainous region and mountainous region and tarai females. Analysis of nasal architecture revels that mountainous region nose were shorter and broader than hilly and tarai region females Conclusions: Evaluation of nasal architecture reveals that shape of nasal dorsum was straight in all three groups of Nepalese females studied. Columella to Lobe relationship showed that Columella was longest in tarai region females followed by hilly region females and shortest in mountainous region females.
