BACKGROUND It has been suggested that botulinum toxin A (BTX-A) treatment for frown lines can also be used as a treatment for depression. A psychological mechanism for this effect is reviewed in which paralysis of the corrugator (frown) muscles leads to less facial feedback for negative emotions. Consequently, a negative affect is harder to maintain and so the person has a more positive mood. ...
Depression is the most important nonmotor symptom in blepharospasm (BL). As facial expression influences emotional perception, summarized as the facial feedback hypothesis, we investigated if patients report fewer depressive symptoms if injections of botulinum neurotoxin (BoNT) include the "grief muscles" of the glabellar region, compared to treatment of orbicularis oculi muscles alone. Ninety ...
Botulinum toxin type A injections are one of the most popular cosmetic procedures for diminishing the appearance of facial lines caused by habitual facial muscle contractions. Although the manufacturer's labeling recommends botulinum toxin only for the treatment of glabellar lines among adults younger than 65 years of age, there is widespread use of the toxin for other cosmetic purposes and for...
UNLABELLED We devised an improved type of the V-Y subcutaneous pedicle flap with the elements of both advancement and rotation flaps. This flexible curved V-Y subcutaneous flap was used for facial skin defect reconstruction in 15 patients. Curved flaps were designed according to the elasticity of the surrounding skin and the postoperative scar direction. RESULTS In all the 15 patients, the fl...
Aim Anthropometric data, particularly cranio-facial variables, is important in forensic medicine, sex determination, designing ergonomic instrument and plastic surgery. The aim of present study is to determine the relation between stature and facial length and facial width among students in Shiraz University of Medical Sciences. Methods This study was done on 201 students (100 males and 101 fem...
Introduction: Cephalometry is an efficient tool for anthropometric studies. This study sought to assess facial dimensions and types of adults residing in Qazvin (Iran) and Dera Ghazi (DG) Khan (Pakistan). Methods: In this cross-sectional study, a total of 300 ethnic populations of Qazvin and 365 ethnic populations of DG Khan aged between 18-55 years were randomly selected and evaluated. Th...
Faces are not simply blank canvases upon which facial expressions write their emotional messages. In fact, facial appearance and facial movement are both important social signalling systems in their own right. We here provide multiple lines of evidence for the notion that the social signals derived from facial appearance on the one hand and facial movement on the other interact in a complex man...
The approach to facial rejuvenation continues to evolve. For decades, the primary focus on rejuvenation has centered on modalities such as skin care, skin resurfacing, soft-tissue augmentation, and surgical intervention. A better understanding of the physiologic changes that occur with facial aging lends itself to new approaches and techniques that are mindful of the causes. As animation has sh...
Numerous lines of evidence point to a genetic basis for facial morphology in humans, yet little is known about how specific genetic variants relate to the phenotypic expression of many common facial features. We conducted genome-wide association meta-analyses of 20 quantitative facial measurements derived from the 3D surface images of 3118 healthy individuals of European ancestry belonging to t...
The concepts of a population and a species play fundamental roles in biology. The existence and precise definition of higher-order hierarchies, such as division into species, is open to debate among biologists. Here we show a new metric, ‘small s’, that distinguishes the population number and various data values that are beyond the range of neutral logarithmic populations and are specific to a ...
