Facial ageing is a gradual process which could be due to intrinsic and extrinsic causes, it ultimately results in the appearance of gravity-induced tissue ptosis, wrinkles, epidermal and dermal atrophy, dryness, senile lentigo, flushing, telangiectasia, and enlarged pores. Mesobotox treatment is a technique of microinjections of diluted Botulinum toxin type A (BTX) to preserve the facial mobili...

In this article, a face recognition algorithm aimed at mimicking the human ability to differentiate people is proposed. For each individual, we first compute a projection line that maximizes his or her dissimilarity to all other people in the user database. Facial identity is thus encoded in the dissimilarity pattern composed by all the projection coefficients of an individual against all other...

introduction: synkinesis and facial asymmetry due to facial nerve palsy are distressing conditions that affect quality of life. unfortunately, these sequelae of facial nerve palsy are unresolved. the aim of this study was to investigate the efficacy of a combination of biofeedback therapy and botulinum toxin a (btx-a) injection for the management of synkinesis and asymmetry of facial muscles.  ...

facial reconstruction is one of the most challenging problems faced by a reconstructive surgeon. we present a case of complex facial reconstruction with a composite trauma to the nose resulting in near total loss of skin and lining along with complete loss of left eyebrow with exposed frontal bone and partial loss of the left eyelid. we combined a temporoparietal fascial flap for reconstruction...

Botulinum toxin injection for treatment of facial wrinkles is the most frequently performed cosmetic procedure in the United States, and it is one of the most common entry procedures for clinicians seeking to incorporate aesthetic treatments into their practice. Treatment of frown lines and crow's feet, which are the cosmetic indications approved by the U.S. Food and Drug Administration, and ho...

We have characterized a strain of double transgenic mice with simian virus 40 large tumor antigen and prokaryotic lacZ under the control of the myelin basic protein promoter that develops spindle-cell sarcomas and osteogenic sarcomas at 5-7 months of age. Although poorly differentiated, the spindle-cell sarcomas were characterized as malignant Schwannomas based on their neural association, the ...

Periodontal surgery associated with prior waxing, mock-up, and the use of digital tools to design the smile is the current trend of reverse planning in periodontal plastic surgery. The objective of this study is to report a surgical resolution of the gummy smile using a prior esthetic design with the use of digital tools. A digital smile design and mock-up were used for performing gingival reco...

background & importance: primary hemifacial spasm is usually caused by microvascular compression of the facial nerve at its root exit zone at brainstem without any space-occupying pathology. secondary or so-called symptomatic hemifacial spasm has an additional underlying pathology e.g. tumors leading to the microvascular compression. we review and discuss the pathophysiology and the literature ...

oral-facial-digital syndrome as heterogeneous developmental conditions is characterized by abnormalities in the oral cavity, facial features and digits. furthermore, central nervous system (cns) abnormalities can also be part of this developmental disorder. at least 13 forms of ofds based on their pattern of signs and symptoms have been identified so far.  type 1 which is now considered to be a...
