ABSTRACT
The anthropometry of nose is an important index to identify a pure race from mixed races . Nasal index isa very sensitive index in nasal anthropometry, as it varies with sex, race and habitat of the person. Theanthropometry of face in general and nose in particular has been used in forensic investigations,reconstructive surgeries and genetic counselling. To study the nasal index in different zones of Jammu andKashmir. 120 students of first professional MBBS Government Medical College Jammu were used assubjects. All of them were in the age group of 18 to 22 years. The length and breadth of the nose wasmeasured by means of digital calliper and the nasal index was calculated using the formula NASAL. Theresults so obtained were tabulated and analysed. LTS. Sexual dimorphism was seen in all the recordedparameters. Anthropometric variation for nasal index is seen in different zones of Jammu and Kashmir.Mean nasal index was 65.98+9.36 for males and 72.15+11.30 for females. Most common type of nasalform in both males and females is leptorrhine or moderately narrow nose.Nasal index plays a significantrole in determining sex and race and so is helpful to forensic investigators .It is also useful for plasticsurgeons while performing rhinoplasty of a particular region as it shows ethnic specificity.
ABSTRACT
Background: The nasal index determination is one of the most commonly used anthropometric parameters in classifying human races. There are few reports in medical literature concerning nasal index that specifically address particular Egyptian populations. The objective of this study was to determine the normal parameters of external nose (width, height and nasal index) in Egyptians. Methods: The study was conducted randomly on healthy Egyptian subjects of both sexes. Nasal height and width were measured using vernier caliper. Then, nasal index was determined for each subject. The obtained data were subjected to statistical analysis. Results: A total of 290 subjects, 144males and 146 females, aged 1month– 65 years, were enrolled in the study. The study showed the existence of sexual dimorphism in nasal morphology, appearing after the age 20 years. The mean nasal index in the investigated adults was 68.01; in males and females was 71.46 and 64.56, respectively. Conclusions: The dominant nasal type in Egyptians was in-between mesorrhine “medium” and leptorrhine “narrow” nose. Forensic and anthropological research, as well as cosmetic and reconstructive surgery may benefit from age- and sex- based data of the study.
