Anthropometric Study of the Nose of 600 North Indian Adults (A study done for forensic identification).

Background: This study was conducted on 600 Adults (300 males and 300 females) of North Indian origin in age group of 18 to 40 years. Method: Prior informed written consent was obtained from the subjects. Exclusion and inclusion criteria for the subjects were predefined. The aim of this study was to document the mean morphometric standards for nose and face of North Indian population which could be of importance in clinical practice and forensicidentification. Nasal height, length, breadth, depth, facial length and breadth were measured using a sliding and spreading caliper.Result: Sexual dimorphism was observed in most parameters of nasal region with all linear measurements being more in Males. Males also had a higher nasal index. Mesorrhine type of nose was found in both sexes. Females had mesoprosopic face whereas males had leptoprosopic face.

An Anthropometric Study of Medial and Middle Crus of Alar Cartilages

The lack of information germane to alar cartilages in Asians led us to conduct a morphologic and anthropometric study. The purpose of this prospective study was to define the shape of the medial crus of alar cartilage and measure their size. Measurements of 42 medial crura of alar cartilages in 21 Koreans were obtained during 21 consecutive primary open approach rhinoplasties between September of 1999 and February of 2000 in the Korea University Guro Hospital. Eight were male and thirteen were female. Measurements parameters of medial crus included shape, length, width, and thickness. In addition, symmetry of the medial crura and length of the middle crus were also investigated. In the male patients(n = 16), the most common shape was the straight shape(n = 9), followed by the simple flared shape(n = 5), complex flared shape(n = 2). The length of the columellar segment ranged from 8-12 mm, the average being 10.0 mm. That of the footplate segment averaged 7.8 mm, ranging from 6-9 mm. The average width and thickness were 4.3 mm and 0.58 mm. Seven patients showed symmetric shape, but one patient did not. The average length of the middle crus was 4.90 mm. In the female patients(n = 26), the most common shape was the straight shape(n = 12), followed by the simple flared shape (n = 11), complex flared shape(n = 3). The length of the columellar segment ranged from 7-9 mm, the average being 8.0 mm. That of the footplate segment averaged 6.3 mm, ranging from 4-9 mm. The average width and thickness were 4.4 mm and 0.56 mm. Ten patients showed symmetric shape, but three patients did not. The average length of the middle crus was 4.9 mm. In conclusion, the most common shape of the medial crus was straight and the average length of footplate segment was 7.0 mm, which is actually greater than that of Caucasian.

An Anthropometric Study of Lateral Crus of Alar Cartilages in Koreans

The lack of information about alar cartilages in Orientals led us to conduct a morphologic and anthropometric study. Measurements of 52 lateral crura of alar cartilages in 26 Koreans were obtained during the 26 consecutive primary open approach rhinoplasties between September 1999 and February 2000 in the Korea University Guro Hospital. Ten were male and sixteen were female patients. Measurement parameters of lateral crus included shape, length, width, thickness, and distance of caudal border from nostril rim. In addition, symmetry of the cartilages and length of the middle crus were also investigated. In case of male patients (n=20), the most common shape was the concave shape (40%), followed by the concave-convex shape (30%). The average length, width, and thickness were 19.7, 10.5 and 0.54 mm. The distance from the nostril rim was 5.7 mm anteriorly, 7.3 mm middle, and 12.3 mm posteriorly. Eight patients showed symmetric shape. The length of the middle crus was 5.0 mm. In the female patients(n=32), the most common shape was the concave shape(50%), followed by the convex(25%) and convex-concave shape(25%). The average length, width, and thickness were 16.8, 9.8 and 0.54 mm. The distance from the nostril rim was 5.8 mm anteriorly, 6.5 mm middle, and 11.5 mm posteriorly. All 16 patients showed symmetric shape and the length of the middle crus was 4.9 mm. In conclusion, we could find that the lateral crus of alar cartilage in Koreans, contrary to popular myth, may not be significantly smaller than that of Caucasian.
