Botulinum toxin (BoNT) injections into facial and bulbar muscles are widely and increasingly used as medical treatments for cervical and facial dystonia, facial hemispasm, correction of facial palsy, hyperhidrosis, as well as cosmetic treatment of glabellar lines associated with grief and anger. Although BoNT treatment is generally considered safe, the diffusion of the toxin to surrounding musc...

Facial expressions are the most powerful and direct means of presenting human emotions and feelings and offer a window into a persons’ state of mind. In recent years, the study of facial expression and recognition has gained prominence; as industry and services are keen on expanding on the potential advantages of facial recognition technology. As machine vision and artificial intelligence advan...

This paper presents an improved edge detection algorithm for facial and remotely sensed images using vector order statistics. The developed algorithm processes coloured images directly without been converted to grey scale. A number of the existing algorithms converts the coloured images into grey scale before detection of edges. But this process leads to inaccurate precision of recognized edges...

acute idiopathic peripheral facial paralysis (bell's palsy) is the most common disorder of the facial nerve. most patients recover completely, although some have permanent disfiguring facial weakness. many studies have attempted to identify an infectious etiology for this disease. although the cause of bell's palsy remains unknown, recent studies suggest a possible association with herpes simpl...

Since its approval by the US Food and Drug Administration in 2002 for glabellar wrinkles, botulinum toxin (BTX) has been widely used to correct facial wrinkles. As a result, many consider BTX synonymous with cosmetic dermatology. Recent studies indicate that BTX elicits biological effects on various skin cell types via the modulation of neurotransmitter release, and it seems that BTX has a wide...

The ever-increasing interest in retaining a youthful physical appearance has facilitated the development of various minimally invasive dermatological techniques. The use of intradermal fillers can be incorporated into dermatological practices with minimal overhead costs. This strategy addresses facial volume loss and dynamic lines, which are the main features of facial aging. Moreover, intrader...

We present a dynamic data-driven framework for tracking gestures and facial expressions from monocular sequences. Our system uses two cameras, one for the face and one for the body view for processing in different scales. Specifically, and for the gesture tracking module, we track the hands and the head, obtaining as output the blobs (ellipses) of the ROIs, and we detect the shoulder positions ...

Borderline personality disorder (BPD) is a serious mental illness characterized by emotion dysregulation. Symptoms related to emotion are thought to contribute to difficulties in perceiving emotional expressions. Individuals with BPD and demographically matched healthy controls completed a task assessing the recognition of happy, sad, and neutral facial expressions at two intensities. Patients ...

Introduction: The primary aim of facial reanimation surgery is to restore tone, symmetry, and movement to the paralyzed face. Hypoglossal-facial end-to-side anastomosis provides satisfactory facial reanimation in the irreversible proximal injury of the facial nerve. This study discussed the facial function results of end-to-side anastomosing of hypoglossal nerve to facial nerve when the i...
