Inter: Ethnic comparison of canthal dimensions between ibibios and ijaws in Nigeria

Canthal index is an important component of craniofacial anthropometry with no universal normative value. It varies greatly among individuals and most especially across ethnic groups. This study was aimed at comparing the canthal index between the Ibibio and Ijaw populations of Nigeria. Four hundred (400) adult participants with ages ranging from 19-31 years were included in the study. Two hundred (200) participants consisting of 100 males and 100 females were randomly selected from the Ibibio and Ijaw ethnic groups of AkwaIbom and Bayelsa states, respectively, in Nigeria. A digital Vernier caliper was used to measure the inner and outer canthal distances and the canthal index was calculated from the values obtained. The results showed that Ibibio males and females had inner canthal distance of 3.49±0.05cm and 3.36±0.03cm; outer canthal distance of 10.34±0.22cm and 10.06±0.15cm, and mean canthal index of 33.77±0.83 and 33.42±0.54, respectively. The Ijaw males and females had inner canthal distance of 3.85±0.12cm and 3.69±0.16cm; outer canthal distance of 11.09±0.16cm and 10.92±0.42cm, and mean canthal index of 34.73±1.02 and 33.71±0.73, respectively. Using z-test (p

A clinical and genetic study of 16 Japanese families with Waardenburg syndrome

The purpose of this study is to profile the clinical and genetic features of Japanese Waardenburg syndrome (WS) patients and validate the W index. Sixteen Japanese WS families with congenital sensorineural hearing loss were included in the study. The inner canthal, interpupillary, and outer canthal distances (ICD, IPD, and OCD) were measured for all patients, and patients were screened for presence of PAX3, MITF, SOX10, and EDNRB mutations. The WS patients were clinically classified under the current W index as follows: 13 families with WS1, 2 families with WS2, and 1 family with WS4. In the 13 WS1 families, genetic tests found PAX3 mutations in 5 families, MITF mutations in 4 families, SOX10 mutations in 3 families, and EDNRB mutations in 1 family. 61% of clinically classified WS1 patients under the current W index conflicted with the genetic classification, which implies W index is not appropriate for Japanese population. Resetting the threshold of W index or novel index formulated with ethnicity matched samples is necessary for clinical classification which is consistent with genetic classification for WS patients with distinct ethnicity.

Normal interpupillary, inner canthal distance and outer canthal distance in a normal population of Pakistan.

Objective:This study was conducted to quantify the normal indices of anthropometric measures related to ophthalmology including Interpupillary distance (IPD), Inner canthal distance (ICD), Outer canthal distance (OCD) in a normal, healthy Pakistani population.Methods:This is a cross sectional study. Total 500 patients were chosen randomly but 499 were included in this study. Patients were selected randomly in an outpatient department of Jinnah Post Graduate Medical Centre Karachi, over the period of five months. IPD, ICD & OCD all measurements were taken with the help of plastic rule by only one researcher to minimize chances of error as much as possible. IPD was reconfirmed from auto refractometer while ICD and OCD readings were taken twice by occluding one eye of researcher to reduce error. Participants were divided into four categories on basis of: Age, Gender, ethnicity and geographical location. Patients were further categorized on basis of Ethnicity to Urdu Speaking, Sindhi, Punjabi, Pathan, and others. Moreover, four age groups were drawn ranging from 15-24 years, 25-44 years, 45-64 years and 65 years and greater.Results:Our study comprised a total of 499 patents of which 272(54.5%) were males, and 227(45.5%) were females. The mean age of the participants was 39.3 ± 14.5 years. The mean values for the IPD, ICD and OCD in mm were 61.8 ± 6.2, 30.9 ± 2.9 and 85.2 ± 6.6 respectively. A statistically significant difference was observed between IPD, ICD and OCD Indices among male and female study participants (p<0.001, p=0.043, p<0.001). While comparing the IPD, ICD and OCD indices amongst the different ethnic groups, we found no statistically significant difference (p=0.09. p=0.28, p=0.06). Overall, there was no correlation between the age and other variables i.e. IPD, ICD, OCD, (r = 0.07, p = 0.085), (r = 0.005, p = 0.906), (r = -0.08, p = 0.058).Conclusion:This work has recommended normative values of IPD, ICD and OCD in Pakistani population on the basis different variables including gender, age, and ethnicity.

An Anthropometric Comparison of Inner Canthal Distance, Outer Canthal Distance and Canthal Index in the Indian and Nepalese Undergraduate Students of Nepalgunj Medical College

Background: The canthal distances are one of the most important aspects in ascessing the facial aesthetics. Several authors have described changes in the canthal distances attributable to race and gender.Aims and Objectives: To compare the inner canntahl distance, outer canthal distance and canthal index in between Nepalese and Indian undergraduate students of Nepalgunj Medical College.Materials and Methods: The study was conducted to compare canthal distances and canthal index among 320 (160 Indians: 100 male,60 female and 160 Nepalese: 100 male and 60 female) undergraduate students of Nepalgunj Medical College of age group 18-24 years at Department of Anatomy, Chisapani, Banke. Inner canthal distance(ICD) and Outer canthal Distance(OCD) were measured by using round end spreading caliper and Canthal Index were calculated by ICD/OCD *100. The value obtained was compared among Indian and Nepalese students in both sexes by using student t-test.Result: The study showed that there was no any significant difference on the value of inner and outer canthal distances and canthal index observed between Nepalese and Indian population except on the value of canthal index which was significantly different between Indian male and Nepalese male population. However, when the comparison was done between the sexes, inner and outer canthal distances and canthal index of males are larger than females except on the value of canthal index of Indian males and Indian females which was non-significant.Conclusion: There occurred a sexual dimorphism within Indian and Nepalese population except on canthal index of Indian male and Indian female but there wasn't any significant differences between Nepalese and Indian population of same sex except on canthal index of Indian male and Nepalese male.

Craniofacial morphometric study of adult Ogoni people of Nigeria

Craniofacial anthropometry requires series of direct standard anthropometric measurement of the bones of the human skull. The study was aimed at establishing baseline data of the craniofacial parameters which are head circumference, intercanthal distances, canthal index and circumference interorbital index of the adult Ogonis of Nigeria. A total of three hundred and eighty two (382) subjects were selected randomly from Kibagha in Gokana local government area, Bori in Khana local government area, Nonwa in Tai local government area and Alesa in Eleme local government area all in Ogoni. Three hundred and eighty two (382) subjects which include one hundred and eighty nine (189) and one hundred and ninety three (193) for males and females respectively with a non-stretchable plastic ruler with 0.5cm interval was used for the measurement and the data. The results showed among others, the mean age value as 30.81±10.13 for male and 32.64±10.91 for female, head circumference (male 56.41±1.52cm, female57.05±2.02cm), intercanthal distance (male 3.56±0.30cm, female 3.47±0.26), outer canthal distance (male 12.53±0.49cm, female 12.39±0.55cm), canthal index (male 28.41±1.79cm, female 28.15±1.83cm) and circumference inter-orbital index (male 6.31±0.44cm, female 6.09±0.40cm). It showed statistical significant difference between the male and female among the parameters measured indicating sexual dimorphism. Discriminate function analysis of Wilkis’ Lambda test also confirms accurateness and predictability of the statistical significant difference of male and female measured variables. The knowledge from the study can provide information for craniofacial assessment for important clinical questions in research especially during surgery on the cranium development forensic investigation in personal identification in the population and society at large.

Reference values of anthropometric measurements in healthy late preterm and term infants

Geographical distribution, ethnicity, and other socioeconomic factors may affect anthropometric measurements, and for that reason each society should determine their own measurements accounting for those factors. In this study, we aimed to determine the anthropometric measurements of healthy late preterm and term infants to compare the results with other national and international studies. This sectional study was carried out among 1197 infants born with a gestational age of ≥35 weeks. Chest circumference, ear length, foot length, palmar length, middle finger length, philtrum distance, inner and outer canthal distances, and palpebral fissure length were measured in the first 24 h of life. All measurements of late preterm infants were smaller than those of term infants (P ˂ 0.05). Compared with male infants, the chest circumference, ear length, foot length, palmar length, philtrum distance, and inner canthal distances of the female infants were lower (P ˂ 0.05). No significant differences were found between male and female infants’ middle finger length, outer canthal distance, and palpebral fissure length measurements. Percentile values for all measurements of 35–42-week male and female infants were described. These measurements of male and female infants born between 35 and 42 weeks may be useful for early detection of syndromes by detecting anatomical abnormalities in our population.

Minor physical anomalies in adolescents at risk for substance use and early sex.

Minor physical anomalies (MPAs) are associated with disruptions of fetal development. We propose that the same genetic compositions that contribute to the presence of MPAs, also predispose individuals to health-compromising behaviors, thus considering MPAs as particular endophenotypes.We developed a screening questionnaire for problematic conduct, substance abuse, and early sexual practice. A total of 108 adolescents (55 males, 50.9%) aged 11 to 19 years were recruited and further divided into case and control groups according to their answers to the questions of health behaviors mentioned above. We then measured their MPAs that included qualitative and quantitative physical features. Stepwise logistic regression and the receiver operating characteristic (ROC) analyses were used to determine the predictive values of MPAs for behavioral outcomes.The obliquity of palpebral fissure and the head MPAs were negatively associated with substance use. In the ROC analysis, the model provided an area under curve (AUC) of 0.91 with prediction indices being 0.89 for sensitivity and 0.85 for specificity. In addition, the feet MPAs and outer canthal distance were positively, whereas the obliquity of palpebral fissure and ear rotation was negatively associated with early sexual practices. The AUC for early sexual practice was 0.91 and the prediction indexes were 0.87 for sensitivity and 0.88 for specificity.Certain MPAs were associated with adolescent substance use and early sex, which suggests a neurodevelopmental etiology for behavioral outcomes

Objectives: To observe the sexual dimorphism among the young adult age group ranging from 18-21 years, of Kathmandu University students by measuring craniofacial circumference and canthal distances.&#x0D; Rationale of the study: These data could be useful for establishing the craniofacial standards and adds an implementation on plastic surgery, crime detection as well as in the industrial field.&#x0D; Method: 300 clinically normal students of Kathmandu University aged between 18-21 years were examined for the study. Fronto-occipital circumference, outer and inner canthal distances were measured. All the parameters were compared between males and females.&#x0D; Result: The cranial circumference as well as the inner and outer canthal distance in males was found to be significantly higher as compared to the females.&#x0D; Conclusion: The results concluded that sexual dimorphism remarkably exists in young adults of Kathmandu University students.

The Latino Eyelid: Anthropometric Analysis of a Spectrum of Findings.

Published anthropometric measurements of the Latino eyelid are limited. This study describes features spanning the morphologic range from non-Latino whites to East Asians in the spectrum of the Latino eyelid. A cross-sectional study of 68 people (32 Latinos, 18 non-Latino whites, and 18 East Asians, ages 18-39), approved by the Institutional Review Board and HIPAA-compliant, was performed. Saliva samples determined genetic components. Indirect anthropometric measurements were performed with ImageJ software. Eyelid measurements included margin reflex distance, palpebral fissure height, eyelid crease height, orbital height, horizontal fissure length, inner and outer canthal distances, medial and lateral canthal angles, and lateral canthal angle of inclination. Additionally, exophthalmometry and epicanthal folds were recorded. Analysis of 184 markers from HumanExome Chip data revealed distinct clustering patterns. Genetically, the Asian participants were in 1 group, the whites in another group, and the Latinos spanned the spectrum between these 2 groups. In Latinos, the inner canthal distance and lateral canthal angle of inclination were similar to Asians, whereas the eyelid crease spanned the range from Asians to whites. Half of the Latinos had epicanthal folds. Latinos possess a spectrum of eyelid features spanning the morphologic characteristics from those of non-Latino whites to those of East Asians. These normative data on Latinos from Texas and Mexico aid in the diagnoses of Latino eyelid disorders and are a reference for optimizing oculofacial surgery outcomes.

Hypertelorism and Orofacial Clefting Revisited: An Anthropometric Investigation.

Since the 1960s, multiple studies have reported a tendency toward hypertelorism in individuals with nonsyndromic orofacial clefts (OFCs). However, the association between specific cleft types and increased interorbital distance has been inconsistent. Using three-dimensional (3D) surface imaging, we tested whether different forms of clefting showed evidence of increased interorbital distance. Intercanthal and outercanthal distances and intercanthal indices were calculated from 3D facial surface images of 287 individuals with repaired OFCs. Raw measurements were converted to sex and age-normalized Z-scores. Mean Z-scores for individuals with cleft lip (CL), cleft lip and palate (CLP), and cleft palate (CP) were compared with reference normative values (controls) and one another directly using t tests and analysis of variance. The CLP group showed a significant increase in intercanthal width (P = .001) and intercanthal index (P < .001) compared with reference norms. The CP group showed a significant decrease (P < .001) in outercanthal width. The CL group showed no difference from reference norms. The proportion of clinically hyperteloric individuals was generally low but highest in the CLP group (7.4%). Cleft severity had little effect on interorbital spacing. Individuals with CLP exhibited on average a tendency toward mild hypertelorism, driven primarily by an increase in intercanthal distance. This tendency was not seen in CL or CP.

Ophthalmology national normative database series (3): Normal ranges of interorbital anthropometric values in healthy sudanese adults

Background: The face is the most distinctive part of the human body. Of all areas on the face, the bilateral orbital regions which are located in the upper half of the face act as a strong influence in the perception of facial attractiveness, esthetic criteria, and “ideal” features of any certain nation. This fact increases the needs for interorbital anthropometry or interocular distances (IODs) which refers to the measurements of the human far interpupillary distance (FIPD), near interpupillary distance (NIPD), outer canthal distance (OCD), and inner canthal distance (ICD) among individuals of different age, sex, and ethnicity. Objective: To assess the normal ranges of interorbital anthropometric values among adult healthy Sudanese population and to define the effects of age, gender, and tribal ethnicity on interorbital anthropometry. Materials and Methods: Systematic interorbital anthropometric measurements were done in 920 Sudanese adults aged 20–85 years. Parameters included were FIPD, NIPD, OCD, and ICD across age, sex, and tribal ethnic perspective of the study subjects. Comparisons were made between their gender, age, and tribal ethnicity using the Chi-square test. Results: The study included 565 female (61.4%) and 355 male (38.6%) subjects with mean age of 48 ± 20 (range 20–85) years. Significant age, gender, and ethnical dimorphism were noted in the following parameters. OCD (male: 92.23 mm; female: 90.79 mm), FIPD (male: 63.20 mm; female: 61.57 mm), NIPD (male: 59.34 mm; female: 57.73 mm), and ICD (male: 34.30 mm; female: 33.00 mm). Conclusion: Significant interorbital measurement differences were found between Sudanese males and females in different age and ethnic groups. The present study suggests that age, gender, and ethnicity should be considered in Sudanese esthetic criteria and “ideal” features in any cosmetic or reconstructive orbital surgery. To individualize the treatment planning and diagnosis, it is important for the surgeons to have knowledge of these local Sudanese interorbital norms.

Ophthalmology national normative database series (4): Normal ranges of interorbital anthropometric values in healthy sudanese children

Background: The knowledge of the normal ranges of interorbital anthropometric values among schoolchildren aged 6–15 years is very important because normal values of facial measurements, inner canthal distance (ICD), outer canthal distance (OCD), canthal index, and circumferential interorbital index are useful parameters in the evaluation and treatment of congenital or posttraumatic deformities of the cephalic and facial regions such as telecanthus, ocular hypotelorism, and craniosynostosis. Objective: To assess the normal ranges of interorbital anthropometric values in schoolchildren and to measure the interorbital distances and to define the effects of age and gender in Al-Shifa area, Khartoum State. Materials and Methods: Systematic interorbital anthropometric measurements were done in 980 schoolchildren aged 5–16 years. Measurements of far Interpupillary Distance (FIPD), Near Interpupillary Distance (NIPD), Outer Canthal Distance (OCD) and Inner Canthal Distance (ICD) were taken in all study population. Comparisons were made between their gender and age using the Chi-square test. Results: In total, 980 individuals were studied. Out of these, 675 (68.9%) individuals were boys and 305 (31.1%) were girls. The mean age of the study group was 9.47 ± 2.71 years; there was a statistically significant difference in all measurements (P Conclusion: Significant interorbital measurement differences were found between Sudanese children according to gender and age. The present study suggests that age and gender should be considered in Sudanese children in any orbital surgery. To individualize the treatment planning and diagnosis, it is important for the surgeons to have a knowledge of these local Sudanese interorbital norms.

Variation of facial features among three African populations: Body height match analyses

Body height is one of the variables that show a correlation with facial craniometry. Here we seek to discriminate the three populations (Nigerians, Ugandans and Kenyans) using facial craniometry based on different categories of body height of adult males. A total of 513 individuals comprising 234 Nigerians, 169 Ugandans and 110 Kenyans with mean age of 25.27, s=5.13 (18–40 years) participated. Paired and unpaired facial features were measured using direct craniometry. Multivariate and stepwise discriminate function analyses were used for differentiation of the three populations. The result showed significant overall facial differences among the three populations in all the body height categories. Skull height, total facial height, outer canthal distance, exophthalmometry, right ear width and nasal length were significantly different among the three different populations irrespective of body height categories. Other variables were sensitive to body height. Stepwise discriminant function analyses included maximum of six variables for better discrimination between the three populations. The single best discriminator of the groups was total facial height, however, for body height >1.70m the single best discriminator was nasal length. Most of the variables were better used with function 1, hence, better discrimination than function 2. In conclusion, adult body height in addition to other factors such as age, sex, and ethnicity should be considered in making decision on facial craniometry. However, not all the facial linear dimensions were sensitive to body height.

Anthropometric Analysis of Orbital Region and Age-Related Changes in Adult Women.

Normal morphometric values of the orbital region vary according to age, sex, and ethnicity. The purpose of this study was to determine the normal values of orbital region and analysis age-related changes in adult women. Measurements were performed on 311 healthy women, aged between 20 and 87. Subjects were divided into 3 age groups: young (20-44), middle aged (45-59), and old adults (60 and up). The anthropometric measurements of orbital region were performed on the photographs by using IT version 3.00 software programs. The mean values of interpupillar distance and nasofrontal angle were 64.20 ± 5.06 mm, 149.21 ± 9.12° respectively. In young, middle, and old groups the values of outer canthal distance were 92.98 ± 5.85, 91.00 ± 7.04, and 88.02 ± 6.13 mm; inner canthal distances were 31.30 ± 3.07, 31.72 ± 3.51, and 31.66 ± 3.44 mm. Palpebral fissure areas were 163.41 ± 29.98, 144.01 ± 30.90, and 129.11 ± 27.21 mm. Palpebral fissure lengths were 29.96 ± 1.76, 28.45 ± 1.96, and 26.81 ± 1.95 mm; palpebral fissure widths were 9.27 ± 1.21, 8.57 ± 1.25, and 7.98 ± 1.18 mm. Inner canthal angles were 39.29 ± 6.04°, 37.57 ± 6.58°, and 35.78 ± 5.80°; outer canthal angles were 53.90 ± 8.90°, 51.48 ± 8.87°, and 49.87 ± 9.78°. Visible iris areas were 96.04 ± 15.04, 88.63 ± 16.27, and 81.73 ± 14.03 mm, respectively. Interpupillary distance and inner chantal distance measurements showed no significant difference with age. As other measurements were determined decreased with age (P <0.05). The authors believe that knowing the normal size of the structures in the orbital region and age-related changes will be useful to maintain the facial proportions in the plastic and reconstructive surgery and to protect aesthetic appearance of the face.

Anthropometric Evaluation of Facial Dimensions in Population of Western Maharashtra

Objective: The present study was carried out to evaluate an average ratio between specific soft tissue parameters of the face among the young adult population of Karad, Maharashtra. The soft tissue parameters gauged in the present study are inner canthal distance, outer canthal distance, alar base width and distance between the corners of the mouth. Rationale: The average ratio of soft tissue parameters of the face can act as a guideline for effective treatment of teeth and dento facial structures as well as soft tissue outlines. Materials and Methods: 1,786 young adults aged between 18 and 20 years from Karad city were initially screened, out of which 1,000 were selected on the basis of the inclusion criteria. The fronto-facial photographs of the selected subjects were captured using a digital camera. The selected facial soft tissue parameters were digitally measured, and the data were subjected to statistical analysis. Result: The values of the parameters measured were marginally more in males; however, the ratio among the parameters was similar in both the sexes. The average ratio between the inner canthal distance, alar base width and distance between corners of the mouth was found to be 1:1.3:1.7, and the average ratio etween the outer canthal distance, alar base width and distance between the corners of the mouth was found to be 2.3:1:1.3 . Conclusion: The different parts of the human face exist in certain proportions. Establishing the ratio between these parameters is important to facilitate proper diagnosis and treatment planning for the specific population. KEYWORDS: Facial measurements, Golden proportions, Digital photography

Assessment of facial golden proportions among central Indian population.

Aim:This study aimed to identify and establish the facial and smile proportions in young adults and to compare the results with ideal or divine proportions, compare the proportions of males and females included in our study population and compare them with those established for Caucasian and Japanese populations.Materials and Methods:Two hundred participants (164 females, 36 males) with Angle's class I malocclusion (M.O). and well-balanced faces were selected and photographed in the frontal repose position. Analysis was done in Adobe Photoshop software. Statistical analysis was done using the Statistical Package for the Social Sciences version 17.0. (IBM Corporation Armonk, New York, United States).Results:Results suggested that females are more near to ideal ratios and males are more deviated from the ideal ratios. The proportions of males and females were not considerably different from each other. In Indian population, upper 3rd facial height (TR-LC) was increased and mid-face height (LC-LN) was decreased; in lower 3rd of the face, LN-CH was slightly increased in comparison to CH-ME. In facial widths, outer canthal width (LC-LC) was greater in the Indian population and mouth width (CH-CH) was normal. When compared with Indian population, Japanese participants had wider noses, outer canthal distance, and bitemporal width.Conclusion:It was concluded that significant difference was found between the proportions of the Indian population and ideal ratio. When Indian population was compared with Japanese and Caucasian populations, some parameters of facial proportions showed significant difference, which leads to the need for establishing standardized norms for various facial proportions in Indian population.

The selection of maxillary anterior teeth width in relation to facial measurements

Objectives: This clinical study was carried out to determine the relationships between maxillary anterior teeth width [canine arc distance, central incisor width], and certain horizontal facial parameters which include: [(Interzygomatic, inner and outer canthus and interpupillary) distances, and (interalar, mouth and philtrum of upper lip) widths], to be used as a guide to selection of the maxillary anterior teeth width.&#x0D; Materials and Methods: The facial measurements were taken directly from (60) under-graduate students in age range (19-24) years old by using an electronic digital vernier caliper. While canine arc distance and central incisor width were measured indirectly on the casts made from impressions of the selected subjects using flexible millimeter ruler. The collected data were analyzed and correlated using statistical package SPSS version 20.&#x0D; Results: The mean value of all the parameters measured were significantly higher in males than female, for male just a significant correlation was found between canine arc distance and mouth width, CARCD =0.994×MW, while for females significant correlation was found between canine arc distance mouth width, inner and outer canthal distance, and interpupillary distance, but the most significance relation was with the mouth width, CARCD=1.036×MW, and central incisor width was significantly correlated with, mouth width, CIW = MW ÷6.15, CIW = MW ×0.16. &#x0D; Conclusions: This study demonstrated that certain horizontal facial parameters could be used as a guide in maxillary anterior teeth width selection to achieve an optimal esthetic result for each gender.

Orbitofacial Assessment of Indian Americans and Its Significance – An Anthropometric Study

Background: For the perception of facial attractiveness, the orbital region in the face acts as a key determinant factor. The Orbitofacial measurements vary with sex and race. Orbital region in the face is one of the most important regions in plastic, reconstructive and ophthalmic surgery and anthropometric evaluation. There are no reports available on the Orbitofacial anthropometry in Indian American population. Objectives: The objectives of the study were to determine the normal average values of linear measurements of the orbital and eyebrow regions and to determine any significant sex differences that exist in the Indian American students of American University of Antigua (AUA), Antigua. Methods: The direct orbitofacial anthropometric measurements (orbital and eyebrow linear measurements, height of the orbit to the length of the eye fissure ratio and canthal index) were carried out using digital caliper in 100 men and 100 women Indian American students (18 to 30 years) of AUA, Antigua and compared between sexes. Results: The orbital and eyebrow linear measurements of Indian American men showed higher value when compared to women. Outer canthal distance, inner canthal distance and thickness of the eyebrow showed statistically significant sexual difference. The palpebral fissure width, height of the orbit and inter eyebrow distance showed no statistical significant sexual difference. Height of the orbit to length of the eye fissure ratio and Canthal index were calculated and showed higher value in men when compared to women. Conclusion: The Orbitofacial anthropometric data obtained in the present study can be used as a reference value for Indian Americans and can be made use in diagnostic procedures, designing of products like optical spectacle frames and lenses, surgical procedures and also in studies involving facial attractiveness.

Dysmorphologic assessment in 115 Mayer-Rokitansky-Küster-Hauser patients.

Mayer-Rokitansky-Küster-Hauser (MRKH) patients are characterized by congenital aplasia of the uterus and the upper part of the vagina, with normal secondary sexual characteristics. This disorders affects one in 4000-5000 females and it is classified as typical, type I or isolated, and as atypical, type II, manifesting additional malformations. To date, no specific study has addressed the question of facial features in MRKH patients. The aim of this study is to perform a dysmorphological assessment of a large cohort of patients. We studied 115 women referred to our center from 2008 to 2012. Seventy-two percentage (83/115) of our patients showed isolated uterovaginal aplasia (MRKH type I); 32/115 (28%) had other abnormalities including kidney and cardiac defects, skeletal anomalies, and hearing impairment. Auxologic investigations comprised measurements of height, weight, BMI, head circumference, arm span, span to height ratio, hand length, middle finger length, foot length, inner and outer intercanthal distance, and auricle length. All patients had normal measurements, except for the outer canthal distance-inner canthal distance ratio, which was consistent with elongated eyelids. Women with MRKH syndromes do not present a typical facial feature and a dysmorphological examination of all patients seems unnecessary. However, a multidisciplinary approach is useful with respect to explaining the etiology, interpreting test results, and counseling.

Eyes of beautiful women and femme fatales depicted in Western portraits.

This study aimed to compare the eyes of beautiful women and femme fatales depicted in Western portraits. A total of 37 samples were collected; 19 beautiful women and 18 femme fatales. Nine aspects were measured in reference to the corneal horizontal diameter. The estimated corneal vertical diameter was calculated by a corneal horizontal diameter multiply constant, 1.11.The double-fold was observed in 89% (17 of 19) of the beautiful women and 83% (15 of 18) of the femme fatales. The eye-width ratio was 2.42 (SD, 0.28) in the beautiful women and 2.31 (SD, 0.34) in the femme fatales. The eye-height ratio was 0.91 (SD, 0.18) in the beautiful women and 0.84 (SD, 0.10) in the femme fatales. Eyebrow-to-upper lid distance was 0.92 (SD, 0.35) in the beautiful women and 0.89 (SD, 0.23) in the femme fatales. The interpupillary distance was 5.00 (SD, 0.46) in the beautiful women and 5.00 (SD, 0.71) in the femme fatales. The intercanthal distance was 2.72 (SD, 0.42) in the beautiful women and 2.78 (SD, 0.73) in the femme fatales The outer canthal distance was 7.32 (SD, 0.64) in the beautiful women and 7.20 (SD, 1.01) in the femme fatales. The ptosis amount was -0.01 (SD, 0.18) in the beautiful women and 0.06 (SD, 0.01) in the femme fatales. For the above 7 measurements, there were no significant differences between the 2 groups (P > 0.05, t test).It is noteworthy that the beautiful women and femme fatales have the same interpupillary distance (5.00). Also, the ptosis ratio was almost zero in both groups (-0.01 [SD, 0.18] in the beautiful women and 0.06 [SD, 0.01] in the femme fatales). The results of this study might be of some reference in performing eyelid surgeries especially in brow lifts or canthoplasties.
