The anthropological analysis of the nasal morphology of Dayak Kenyah population in Indonesia as a basic data for forensic identification

The primary intention of forensic identification is the establishing of human identity, including sex, race, and ages. The nasal index is one of the important parameters to determine race and sex through the nasal morphology. Therefore, basic data of nasal index is necessary to be specifically used in observing nasal morphology variation that has been influenced by regional and climatic factors. This study conducted in the Sub-Dayak Kenyah population in North Kalimantan, Indonesia, as an indigenous population of Kalimantan Island. The nasal index mean and SD of males and females were 77,87 ± 10,8 and 78,46 ± 7,97 respectively. The dominant type of nasal shape for Dayak Kenyah males and females was mesorrhine with the second most common type was platyrrhine. There was a difference in the nasal shape between the present study and the previous study. The results of this study can be used to trace the origin of populations in Indonesia, especially North Kalimantan and important for the database in forensic science and anthropology.

Variation in Facial Index and Nasal Index in Western Maharashtrian Males- An Anthropometric Study

Introduction: Facial anthropometry had proved its great importance in the field of facial reconstructive surgery as well as in the field of forensic science. Specific face types and nose types provides us important information about specific types of races. Aim: To study the morphometric variation in facial index and nasal index as well as different types of faces and types of noses in the Western Maharashtrian males. Materials and Methods: An observational study was carried out in the five cities- Sangli, Kolhapur, Islampur, Karad and Satara of Western Maharashtra, India. Total 535 male students of different colleges between the age group of 18-20 years were selected and measurements were taken with the help of Digital Vernier Calliper in the sitting position after due approval from Institutional Ethical Committees and informed consent. The methodology adopted for the measurements was taken from the guidelines given by Farkas LG in his book-“Anthropometric facial proportions in Medicine”. Results: The mean facial index of Western Maharashtrian males was 89.51 with standard deviation 4.26 and dominant face type was leptoprosopic which was 46.73% and rare type of face was hypereuriprosopic which was 0.19%. Mean nasal index of Western Maharashtrian males was 72.84 with standard deviation 6.86 and dominant nose type was mesorrhine which was 63.74%. Conclusion: Certain facial and nasal features are common in particular racial group. Its detection can be helpful in reconstructive facial surgeries.

Morphometric variations of nasal parameters in gujarati population: An anatomical study

Introduction: Nasal morphology is an important factor in forensic investigations and facial reconstructive procedures. Found to be strongly related to ethnicity and environmental factors, and known to be sexually dimorphic, the study of nasal parameters is useful in forensic facial reconstruction. The aim of the study is to evaluate the nasal morphological characteristics of the Gujarati population as an indicator for personal identification and to assess the prevalent nasal morphology of the study population determined. Material and Methods: The study involved randomly selected 180 healthy subjects (90 males and 90 females) between three age groups. Nasal width and nasal height were measured using a digital vernier caliper, and nasal index was calculated along with other parameters. The data were statistically analyzed. Results: The mean nasal width for male and female was 38.23 mm and 34.94 mm while the mean nasal height was 47.59 mm and 44.35 mm, respectively. The mean nasal index for male subjects (81.08) was also higher than for female subjects (77.30). The morphological classification showed the mesorrhine nose type as the most prevalent among both the males (58.88%) and females (66.66%). Discussion and Conclusion: The population under the study exhibits mesorrhine type of the nose and shows sexual dimorphism in the values of nasal measurements. Thus, the current study is valuable not only in forensic facial reconstruction but also as an added method for determining the gender and ethnicity of an unidentified individual.

Morphometric study of nasal parameters in adult jaunsari tribe population of Dehradun district of Uttarakhand

Introduction: Physical anthropometry has been helpful in clinical diagnosis, forensic medicine, orthodontics, plastic, and reconstructive surgery. The Jaunsari tribe is a unique tribal community of Uttarakhand. There is lack of anthropometric study on them. Hence, it was planned to study facial anthropometric parameters specially that of the nose, in adult Jaunsari tribe of district Dehradun, Uttarakhand. With objectives (1) To study the nasal anthropometric parameters of adult males and females. (2) To analyze the sex differences, if any. (3) and its statistical significance. Material and Methods: The study was carried on 100 adult males and 100 adult females of >18 years of age, belonging to Jaunsari tribe, after due approval from the Institutional Ethical Committee and informed consent. The methodology adopted for the anthropometric measurements was of Singh and Bhasin, and concerned measurements were taken and appropriate statistical tests were applied. Results: Nasal index, parameters related to it and total facial height are statistically significantly different among males and females. Sagittal Naso-facial Index and Elevation of Nose Index are 44.93 ± 3.79, 44.22 ± 3.18 and 69.23 ± 17.13, 65.70 ± 8.73 in females and males, respectively, which mean relatively elevated and shorter nose. Discussion and Conclusion: The most common nose type in females is leptorhinae (60%), whereas in males both leptorhinae and mesorrhine type of nose are equally (47%) prevalent. Predominant nasal breadth in male (69%) and in female (68%) is above medium type, whereas predominant nasal height in male (42%) and in female (50%) is above medium type and below medium type, respectively.

Nasal Parameters and Facial Index in Medical Undergraduates: A Cross Sectional Study

Introduction: Face has priority in identification of an individual. Nose occupying the middle of face is animportant sense organ that helps in respiration. Nose and face can be classified into different types accordingto nasal index and facial index. The aim of this study was to analyze nose and face type and find out itsdominance in different sex of Nepalese and Indian population. Methods: This was a quantitative observationalstudy conducted on 156 medical students using simple sampling method. Data were collected then nasalindex and facial index were calculated. Descriptive statistical data i.e. mean, standard deviation, togetherwith the independent-samples t-test results for anthropometric variables of nasal and facial parameters insex and Nationality (Nepalese and Indian) were analyzed. Results: All the measurement values were morein males compared to females, but the sexual dimorphism in nasal index (male 76.25 ± 7.75, female 75.70± 8.05) and facial index (male 85.77 ± 8.1, female 82.97 ± 7.63) is not statistically significant. Chi-squaretest revealed significant difference in face type among Nepalese and Indian population. Mesorrhine wasthe most common type of nose in both the population. Nepalese had commonly euryprosopic type of facewhile Indians had hypereuryprosopic type of face. Conclusion: Sexual dimorphism was not significant inboth nasal and facial parameters while type of face was helpful in differentiation of Nepalese and Indianpopulation.

Nasal index among Students of People’s Dental College and Hospital

Introduction: Nasal anthropometry is a study that deals with the measurements of the proportion, size, and shape of nose. The nasal index is considered as one of the major landmarks for craniofacial surgery, gender differentiation, and ethnic identity. This study is aimed to provide baseline data of the nasal index of Nepalese people and to assess the gender variation which will be of clinical, surgical interest in rhinology and craniofacial prosthetic purpose.
 Methods: BDS students from 17 to 25 years with various ethnicity were included in the study. A total of 160 students with an equal number of male and female students was included. Nasal parameters were measured and the nasal index was calculated for each student.
 Result: The mean nasal index was 78.03±7.07 suggesting Mesorrhine type of nose. The nasal width and height show statistically significant difference whereas there was no significant difference found between the nasal indices of male and female students. Hill Janajati showed the highest nasal index followed by Newar, Brahmin and Chettri; and Others.
 Conclusion: The study concludes the type of nose has an effect on gender when compared between the sex but the nasal index calculated to have a little contribution to sexual dimorphism. Mesorrhine nose were found to be most frequent. Among the population, Hill Janajati showed highest nasal index. We recommend a further study to compare the nasal index of various ethnical groups of Nepalese population.

Comparison of Nasal Index Between Northwestern Nigeria and Northern Iranian Populations: An Anthropometric Study.

The nasal index has a great value in anthropological studies, because it is one of the anthropometric indices acknowledged in nasal surgery as well as management. Anthropometric studies are very important area for craniofacial surgery and syndromology. The aim of this research was to compare the nasal characteristics between northwestern Nigerian and Iranian populations and compare them with other studies. The nasal breadths and heights were measured from 400 individuals with 200 participants from Hausa ethnic group of northwestern Nigeria and 200 participants from Northern Tehran, Iran. Nasal index (NI) was calculated and analyzed statistically. There were significant difference in the nasal breadth (P = 0.0001), height (P = 0.0001) and NI (P = 0.0001) of sex groups in both Iranian and Nigeria population. The distribution of the nasal shapes for Iranian population is 127 leptorrhine (31.9%), 62 mesorrhine (15.6%) and nine platyrrhine (2.3%), while Nigeria population has 120 mesorrhine (30.2%), 75 leptorrhine (18.8%) and five platyrrhine (1.3%). This shows that Nigeria Hausa population has predominantly mesorrhine nose shape, while Northern Iranians are leptorrhine. The NI of males is higher than females in both population and this study can be ofclinical and surgical interest in Rhinology. We recommend further studies to compare the NI of Nigeria and Iranian population of different ethnic groups and with other countries.

Estimation of sex in Brazilian samples with cross-validation in populations of different regions

Sex estimation might be influenced by ancestry and Brazilian population is cross cultural. Skulls are often used for estimating sex dimorphism. The purpose of the present study was estimate sex based on five craniometric measurements from contemporary and identified samples from two different Brazilian regions with cross-validation. Ethnic group was estimated by Nasal Index and Prosopometric Facial Index. A population sample from South region of Brazil was used to estimate a model (train) and then its performance was tested in a population sample from the Southeast region (test). In a second moment, we performed analysis inverting the order or the populations. The two samples (Southeastern-Southern) were united in one group, in order to verify the influence of this union in the prediction of sex. Models with one, two, three independent variables were created using binomial logistic regression. The results revealed that sex estimation is best performed without the interference of the variable ancestry. Three craniometric measurements allowed a more predictive model for populations with high degree of cross cultural, as the Brazilian one. United samples, Southeastern-Southern, resulted in a good prediction (AUC=0.85), but an intermediate value between southern (AUC=0.89) and southeast (AUC=0.81). It is concluded that sex estimation is best performed without the interference of the variable ancestry. Three craniometric measurements allowed a good predictive model for the Brazilian Southern and Southeastern populations.

Efficacy and safety of electric heating moxibustion for perennial allergic rhinitis: protocol for a randomized controlled trial

BackgroundAllergic rhinitis (AR) is an IgE-mediated disease that adversely affects quality of life. Many studies report that moxibustion is an effective treatment for perennial allergic rhinitis (PAR). However, it is difficult to perform moxibustion on the face because of possible burning of the skin and the noxious effects of smoke. Electric heating moxibustion does not have these limitations. The purpose of this clinical trial is to assess the possibility of treating PAR with electric heating moxibustion and to assess the feasibility of conducting a clinical test on a larger scale.MethodsThis is a randomized, open-label, assessor-blind, parallel-design pilot clinical study. We will recruit 40 eligible participants and randomly allocate them into an electric heating moxibustion group or an acupuncture group at a 1:1 ratio. Patients in both groups will receive eight treatments over 4 weeks, and the final follow-up will be 4 weeks after the last treatment. Eleven acupuncture points will be used for patients in both groups (EX-HN3 and bilateral EX-HN-8, LI20, LI4, GB20, and ST36). The primary outcome measure is change in the Total Nasal Symptom Score, and the secondary outcome measures are changes in the Rhinoconjunctivitis Quality of Life Questionnaire, nasal endoscopy index for pattern identification, pattern identification questionnaire for AR, total IgE, eosinophil count, and adverse effects.DiscussionThis clinical trial will examine the effect of electric heating moxibustion on PAR.Trial registrationClinicalTrials.gov, NCT03342105.

A Novel Approach for Investigating Upper Airway Hyperresponsiveness Using Micro-CT in Eosinophilic Upper Airway Inflammation such as Allergic Rhinitis Model.

Airway hyperresponsiveness (AHR) has been proposed as a feature of pathogenesis of eosinophilic upper airway inflammation such as allergic rhinitis (AR). The measurement system for upper AHR (UAHR) in rodents is poorly developed, although measurements of nasal resistance have been reported. Here we assessed UAHR by direct measurement of swelling of the nasal mucosa induced by intranasal methacholine (MCh) using micro-computed tomography (micro-CT). Micro-CT analysis was performed in both naïve and ovalbumin-induced AR mice following intranasal administration of MCh. The nasal cavity was segmented into two-dimensional horizontal and axial planes, and the data for nasal mucosa were acquired for the region of interest threshold. Then, a ratio between the nasal mucosa area and nasal cavity area was calculated as nasal mucosa index. Using our novel method, nasal cavity structure was clearly identified on micro-CT, and dose-dependent increased swelling of the nasal mucosa was observed upon MCh treatment. Moreover, the nasal mucosa index was significantly increased in AR mice compared to controls following MCh treatment, while ovalbumin administration did not affect swelling of the nasal mucosa in either group. This UAHR following MCh treatment was completely reversed by pretreatment with glucocorticoids. This novel approach using micro-CT for investigating UAHR reflects a precise assessment system for swelling of the nasal mucosa following MCh treatment; it not only sheds light on the mechanism of AR but also contributes to the development of new therapeutic drugs in AR patients.

Three-Dimensional Nasal Alterations in Le Fort I Advancement: Linear Measurements, Angles, Nasal Indices, and Volume Differences.

The maxillary advancement obtained by the Le Fort I osteotomy can also generate significant changes in the soft tissue of the nose and lips. The aim of this study was to compare the alterations in the soft tissue of the nose following the Le Fort I osteotomy maxillary advancement technique in a population of young adults submitted to orthognathic surgery. Seven men and 8 women aged between 23 and 45 underwent orthognathic surgery using the Le Fort I osteotomy and bilateral mandibular sagittal osteotomy. Sixty 3-dimensional images were analyzed (Vectra M3, Canfield, NJ) after labeling landmarks on the face and determining linear and angular measurements, proportion, and volume difference indices at the following intervals: preoperatively (baseline), then 2 months, 6 months, and 1 year after surgery. Following Le Fort I, there was an increase in the alar base, and reduction of nasal tip protrusion, nasal angles, and the nasal tip protrusion index (P < 0.05). There were no differences in the facial thirds, the nasal index, and angles of nasal and mentolabial convexity (P > 0.05). There was a difference in the volume of the nose only 2 months after surgery. The Le Fort I osteotomy caused significant alterations in linear, angular, and nasal proportion measurements. The volume differences were reversible in the early postoperative period and probably associated with edema. The possibility of variations in the size and shape of the nose should be presented to prospective patients preoperatively.

Long-Term Nasal Growth after Primary Rhinoplasty for Bilateral Cleft Lip Nose Deformity: A Three-Dimensional Photogrammetric Study with Comparative Analysis.

Nasal deformity is associated with congenital cleft lip and palate. Primary rhinoplasty for reconstruction of the nasal deformity at the time of bilateral cleft lip repair is a controversial issue in cleft care due to traditional teaching concerning the potential impairment of nasal growth. This study assessed long-term nasal growth in patients with bilateral cleft lip and palate who underwent primary rhinoplasty by a single surgeon between 1995 and 2002 and reached skeletal maturity (n = 39; mean: 19 ± 2 years). Normal age-, gender-, and ethnicity-matched subjects (n = 52) were enrolled for comparative analyses. Three-dimensional nasal photogrammetric measurements (10 linear, 4 angular, 6 proportional, 1 surface area, and 1 volume parameter) were collected from patients with bilateral cleft lip and palate and normal subjects. Patients who underwent rhinoplasty presented with significantly (all p < 0.05) smaller nasal tip projection and nasal tip angles, but greater values for nasal dorsum length, nasal protrusion, alar width, columellar height, dome height, columellar angle, labiocolumellar angle, nasal tip height ratio, nasal index, alar width/intercanthal distance ratio, and alar width/mouth width ratio compared to normal subjects. There were no differences (all p > 0.05) in nasal height, tip/midline deviation, nasal dorsum angle, dome-to-columella ratio, columella height/alar width ratio, area surface, and volume parameters between the two groups. This study shows that primary rhinoplasty performed in patients with bilateral cleft lip and palate during infancy does not result in deficiency of the nasal dimensions relative to controls.

Mean Nasal Index of Dental Students of A Dental College in Nepal

Human nose is one of the important anthropometric parameters for identification of sex and ethnicity of an individual of an unknown identity. The nasal index holds a great value in anthropological studies, because it is one of the anthropometric indices acknowledged in nasal surgery as well as management. The study aims to find the mean nasal index and the nose type of dental students of Kantipur Dental College of Nepal. This descriptive cross-sectional study was conducted among 140 dental students in the Department of Anatomy, Kantipur Dental College Teaching Hospital and Research Center, Basundhara, Kathmandu. The studied population belongs to dental students of Kantipur Dental College and Research Centre. The nasal parameters include nasal height, nasal width which was measured using Digital Vernier Caliper and the nose was classified in three different types based on the value of nasal index. The mean nasal index of total population was 81.34±14.88 mm with confidence interval range of 78.85 and 83.83 mm. Mesorrhine type of nose was found to be most common among the total population. Mean nasal index in male is 84.49±12.46 mm and in female is 80.66±15.32 mm. This study concludes that the mean values of nasal index of the students fall under mesorrhine type of nose.

Nasal Parameters, Nostrils Shapes and Philtral Column Shape: A Morphometric Analysis in Nepalese Medical Undergraduate Students

The nose is a pyramidal shaped structure situated in the midline of midface being attached to the facial skeleton. The shape, size and spatial location of the nose-philtrum-upper lip complex are important from aesthetic point of view. Hence, to study the nasal parameters, shape of nostril and philtrum among the undergraduate students remained as the main aim of this study. This was a cross-sectional study enrolling 250 students of age 18-25 years. Nasal height, nasal width was measured and the shape of the nostrils and philtrum was recorded separately for each participant. Out of 250 participants 113 were males and 137 were females. The mean nasal index of male was 75.36 while that of female was 71.72 suggesting that both genders had mesorrhine nasal type. The rectangular shaped nostrils and triangular type of philtrum was the most common types found in the study Conclusions: The study concluded that, the nasal index was mesorrhine type, the nostril was rectangular and the philtrum column was triangular in this study population.

The Possibilities of Multislice computed Tomography in nasal Anthropometry

Background. Nasal anthropometry is an important aspect of maxillofacial and plastic surgery especially in the preoperative stage of rhinoplasty. Multislice computed tomography (MSCT) permits to assess quantitative the variant nasal anatomy using measuring.Aims: to determine the possibilities of MSCT-anthropometry in nasal configuration grade.Materials and methods. We performed a proand retrospective analysis of MSCT data of maxillofacial region of 50 patients (aged 35 ± 10.7 years old) with changes of nasal height and width and 35 women (32.9 ± 8.4 years old) with normal nasal configuration. The variant anatomy consists in long nose (n = 16), short nose (n = 17), wide nose (n = 17). The nasal height was measured from the nasal root (nasion) to the nasal base (subnasion), the nasal width is the distance between the most lateral aspects of the alae nasi. Besides, the nasal index was calculated. The descriptive statistics of obtained data were presented by mean and standard deviation (SD), also the multiple regression analysis was used. Values of p = 0.005 were considered statistically significant.Results. The results showed that the average nasal height in patients with normal configuration is 51.9 ± 2.63 mm, with short nose – 45.2 ± 1.36 mm, with long nose – 60.3 ± 1.28 mm. The mean nasal widths are 34.9 ± 1.88 mm in normal configuration, 38.8±3.57 in wide nose. The nasal indexes were calculated, their features were detected. These obtained results correlate with anthropometric data of different studies.Conclusions. MSCT-anthropometry is an objective imaging method of variant nasal anatomy that could provide improving quality of diagnostics of patients seeking rhinoplasty and choose a surgical approach.

Nasal Anthropometry of Adult &amp;lt;i&amp;gt;Tiv&amp;lt;/i&amp;gt; and &amp;lt;i&amp;gt;Idoma&amp;lt;/i&amp;gt; Tribes of Nigeria

Nasalanthropometry measures nasal parameters for ethnic morphological nasal classification and categorization. This study was carried out to determine the nasal index in the target population and compare it in both sexes and with the result of other similar studies. The sample consisted of 600 youths aged 18 - 32 years. Data were collected through self-administered questionnaire to establish ethnic background. Nasal length and nasal breadth were measured using vernier calipers and the nasal index calculated according to standard formula. Statistical analysis was done using SPSS for windows version 20 (IBM Corporation, New York, USA). Statistical significance was considered at p ≤ 0.05. The mean nasal length of Tiv was 4.4 ± 0.63 cm and the mean nasal breadth was 4.2 ± 0.59 cm. The mean nasal length of Idoma was 4.3 ± 0.67 cm and the mean nasal breadth was 3.9 ± 0.61 cm. There was a statistically significant mean difference in nasal breadth between the two ethnic groups (p = 0.001) with higher mean value in Tiv relative to Idoma. Both ethnic groups exhibited sexual dimorphism of nasal length, nasal breadth and nasal index with males having significantly higher mean values than females (p < 0.05). The mean nasal index of Tiv was 95.7 ± 10.97 while that of Idoma was 92.3 ± 11.03. Based on nasal index, it was concluded that the nose type in the two ethnic groups was platyrrhine.
