Aim The submental-cervical angle may alter as a result of mandibular orthognathic surgery and/or the ageing process and is therefore an important facial aesthetic parameter for comparative diagnosis and treatment planning. The purpose of this study was to undertake a quantitative evaluation of the influence of the submental-cervical angle on perceived attractiveness and threshold values of desire for surgery. Study Design The submental-cervical angle of an idealized profile silhouette image was altered incrementally between 90°and 130°. The images were rated on a sevenpoint Likert scale by pre-treatment orthognathic patients (n = 75), laypeople (n = 75), and clinicians (n = 35). Results A submental-cervical angle of 90°-105°was deemed acceptable. Angles up to 120°were deemed slightly unattractive by the lay and clinician groups, but very unattractive by the patient group. By 125°-130°all groups perceived the angle as very unattractive. The threshold value of desire for surgery was 110°for patients, 115°for lay people and 125°for clinicians. Patients appear to be more critical than lay and clinician groups. Conclusions These ranges of normal variability of the submental-cervical angle and threshold values of desire for surgery, in terms of observer acceptance, should be considered by clinicians in planning mandibular orthognathic surgery and aesthetic surgical procedures of the submentalcervical region.

“…Each observer was given a questionnaire and asked to provide the following information: age, gender, ethnic origin (White or non-White), how would you rate the attractiveness of your facial appearance, and how important do you think it is to have an attractive facial 4 appearance. An instruction sheet accompanied the questionnaire, asking the observers to rate each image in terms of facial attractiveness using the following rating scale: Observers were also asked whether they would consider surgery to correct the appearance if this was their facial appearance (yes or no).…”

“…The image was manipulated using the same software to construct an "ideal" profile image with proportions, 3 and linear and angular soft tissue measurements, 3,[6][7][8] based on currently accepted criteria for an idealized Caucasian male profile, as previously described. 4 The nasofrontal angle of the idealized image (image BK: 130°) was altered in 3-degree increments from 148 to 106 degrees, in order to represent variations in the angle and morphology of the nasofrontal region, ranging from an excessive nasal dorsal hump to a ski slope dorsal morphology ( Figure 2). …”

Nasofrontal Angle and Nasal Dorsal Aesthetics: A Quantitative Investigation of Idealized and Normative Values

Background: A quantitative evaluation of the influence of the lower component of the nasofrontal angle on perceived attractiveness and threshold values of desire for rhinoplasty. Methods:The nasofrontal angle of an idealized silhouette male Caucasian profile image was altered incrementally between 106° to 148°. Images were rated on a Likert scale by pretreatment patients (n=75), laypeople (n=75), and clinicians (n=35). Results:The results demonstrate that a nasofrontal angle of approximately 130° is ideal, corresponding to a lower component of 60°, with a range of 127° to 142° deemed acceptable.Angles above or below this range are perceived as unattractive, and anything outside the range of 118° to 145° is deemed very unattractive. Reduced nasofrontal angles, simulating a nasal hump deformity, of less than 115° were deemed the least attractive.In terms of threshold values of desire for surgery, for all groups a threshold value of 148° indicated a preference for surgery; for patients 121° or less, for lay people the threshold value was 124° or less and similarly 118° or less for clinicians.Clinicians were the least critical, and patients appeared to be less critical than lay people.This stresses the importance of using patients as observers, as well as laypeople and clinicians, in facial attractiveness research. Conclusions:From the results of this study, it is recommended that in rhinoplasty planning, the range of normal variability of the nasofrontal angle, in terms of observer acceptance, is taken into account as well as the threshold values of desire for surgery.

“…Besides, patient demands have increased in the search of an exclusive orthodontic treatment, which is based on standards derived from their race or specific ethnic group. 16 Given the anthropological differences of facial and dental standards, Miura, Inoue and Suzuki 18 concluded that, besides having different values, the treatment target for the Japanese should also be different from the Caucasian. Although respecting the patient's expectations, it is important to make them aware of the effects that certain changes may bring.…”

Objective: To determine the normality mean values in the soft tissue cephalometric measurements of young Japanese-Brazilian, with normal occlusion and compare the results of the variables with compatible samples of young Caucasians and Mongoloids. Methods: Forty radiographs of young Caucasians, 32 of Japanese-Brazilians and 33 of Mongoloids were used. The three samples presented individuals with normal occlusion and well-balanced face. The samples were divided by gender due to the soft tissue characteristics and to facilitate comparison. The following statistical tests were performed: Analysis of variance (ANOVA) and analysis of covariance (ANCOVA) with p < 0.05. Results:The Japanese-Brazilian sample of females showed thinner soft tissues in the nasion region and smaller nose when compared to the Caucasians. The Mongoloid sample showed thinner tissues in the supramentonian and pogonion regions. In males, the Japanese-Brazilians had thinner tissues in the nasion region; thicker lower lip and supramentonian region in comparison to the Caucasian sample. For the Mongoloid, soft tissue was thicker in the glabella and ANS-Sn regions. Conclusion: It is necessary to use specific soft tissue standards for this mixed race. Keywords: Ethnic groups. Reference values. Orthodontics.Objetivo: determinar os valores médios de normalidade das grandezas cefalométricas tegumentares de jovens mestiços nipo-brasileiros com oclusão normal, e compará-los com amostras compatíveis de jovens brasileiros leucodermas e xantodermas. Métodos: foram utilizadas 40 telerradiografias de jovens leucodermas, 32 de nipo-brasileiros e 33 de xantodermas. As três amostras apresentavam indivíduos com oclusão normal e face bem balanceada. As amostras foram divididas por sexo devido às características do tecido mole e para facilitar a comparação. Foram realizados os testes estatísticos análise de variância a um critério (ANOVA) e a análise de covariância (ANCOVA) com p < 0,05. Resultados: a amostra nipo-brasileira para o sexo feminino apresentou menor espessura na região do násio e menor nariz em relação aos leucodermas. Em relação à amostra xantoderma, menor espessura na região supramentoniana e pogônio. No sexo masculino, os nipo-brasileiros apresentaram menor espessura na região do násio, maior espessura do lábio inferior e da região supramentoniana em relação à amostra leucoderma. Em relação aos xantodermas, maior espessura na região da glabela e da ENA-Sn. Conclusão: verificou-se a necessidade de se utilizar normas de tecido mole específicas para essa raça miscigenada.Palavras-chave: Grupos étnicos. Valores de referência. Ortodontia.
