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: Nose is an important anatomical and physiological part of face. Its anatomy considerably affectsits function of inhalation and temperature regulation of inspired air. The anatomy is affected by genetic, racialas well as geographical factors. The aim of the study was to measure nasal height and width in the populationbeing studied so as to calculate nasal index and classify noses on the basis of calculated index.Materials and method: The study was conducted on 159 healthy volunteers aged 18-25 years in Medical CollegeBaroda, Gujarat. Nasal height and Nasal width were measured by digital vernier caliper and the nasal index wascalculated. The type of nose was determined on the basis of the nasal index.Results: In the present study the mean nasal index is found to be 73.28+10. Mean nasal index is observed as106.46+6.24 in males & 71.94+8.02 in females. The t test value calculated is 26.725 at CI 95% with P<0.0001showing highly significant difference in nasal indices of male and female. Mesorrhine is the commonest nasaltype found.Conclusion: The study will be highly useful to plastic surgeons, craniofacial surgeons, otolaryngologists,anatomists, forensic experts, orthodontists and medical illustrators alike.
ABSTRACT
Introduction: Nasal parameters are important for estimation of stature, gender identification and age estimation. Commonly used Nasal parameters are Nasal height, Nasal breadth and Nasal width; Nasal height is one of the most reliable of which. Previous studies have reported racial differences and geographical variation in Nasal height along with importance in gender differentiation. This study was conducted with aim to measure Nasal heights of Bhavangar city population and check for Nasal height differences among males and females. Subjects and Methods: 510 subjects (243 male and 267 female) were enrolled in the present cross-sectional study, conducted at Government Medical College, Bhavanagar in 2011 after institutional ethical committee approval. Age group of the subjects enrolled in the study was 18 to 30 years. Nasal height was measured with the help of sliding caliper after informed and written consent of the subject. The data was compiled and analyzed with standard statistical methods by Microsoft excel and Epiinfo 7.0TM software. Results: Difference in mean nasal height of Males (46.241 ± 3.518 mm) and females (43.799 ± 3.419) was statistically significant at 95% confidence interval (p value = 0.0001). Conclusion: Nasal height can be used as one of the parameters for gender determination of the subject.
ABSTRACT
Estimation of stature from body segment parameters finds usefulness in forensic sciences and other medical applications. However, these parameters are highly, sex, race and age dependent. The present study measured some cephalofacial parameters with a view to providing cephalofacial anthropometric parameter that could be used in estimation of stature among teenage indigenes of Ogoja Local Government Area of Cross River State. A total of 300 teenagers (13-19 years), comprising 150 males and 150 females were used. Maximum stature, head circumference, nasal height and nasal width were obtained by direct measurement. The findings of the study showed that males mean values are significantly higher (p<0.05) than females for all parameters: Stature (males, 157.30±6.81; females, 155.70±5.71), head circumference (males, 55.38±1.55; females, 54.62±1.52), nasal height (males, 4.54±0.43; females, 4.39±0.44) and nasal width (males, 4.95±0.50; females, 4.74±0.58). Results of this study reveals that male head circumference significantly (p<0.05) correlate with stature. Hence only male head circumference (HC) could be employed in the estimation of stature using the linear regression equation (11.48 × HC + (-478.70)). The analysis of the measured parameters shows that nasal height and width are not reliable tools for stature prediction amongst Ogoja teenage population.
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.
