A 22-year-old woman visited our clinic with a history of radiofrequency volumetric reduction for bilateral masseter muscles at a local medical clinic. Six days after the radiofrequency procedure, she noticed a facial asymmetry during smiling. Physical examination revealed immobility of the mouth drawing upward and laterally on the left. Routine nerve conduction studies and needle electromyograp...

Although facial symmetry correlates with facial attractiveness, human faces are often far from symmetrical with one side frequently being larger than the other (Kowner, 1998). Smith (2000) reported that male and female faces were asymmetrical in opposite directions, with males having a larger area on the left side compared to the right side, and females having a larger right side compared to th...

OBJECTIVE To evaluate the craniofacial asymmetry in adults with neglected congenital muscular torticollis (CMT) by quantitative assessment based on craniofacial three-dimensional computed tomography (3D-CT). METHODS Preoperative craniofacial asymmetry was measured by 3D-CT for 31 CMT subjects ≥18 years of age who visited a tertiary medical center and underwent 3D-CT between January 2009 and D...

Fractures of the mandible and middle third of the facial skeleton are most commonly the result of road traffic accidents or physical combat (Hagan and Huelke, 1961; van Hoof, Merkx and Stekelenburg, 1977; Starkhammar and Olofsson, 1982; Brook and Wood, 1983). In recent years the introduction of compulsory seat belt legislation has decreased the incidence of these injuries in the UK (Price, 1983...

Hemifacial microsomia is most often diagnosed at birth and comprises varying degrees of malformations one side the face. Depending on involved, multiple procedures are required as primary treatment approaches, embedded in an interdisciplinary concept from to adolescence. However, with regard symmetry face, soft tissue bony discrepancies between normal affected remain recognizable or even persis...

Sixty-seven patients with sternomastoid tumours have been treated by stretching and manipulation of the neck and the results evaluated after an average follow-up of six and a half years. Stretching was found to be useful in early management, although initial facial asymmetry and limitation of neck rotation of over 30 degrees usually precluded a good prognosis. The results were also unsatisfacto...

One of the most common sites of injury of the facial skeleton is mandibular condyle. However, it is the least diagnosed site of trauma in the head and neck regions. A trauma to the mandible and specifically condylar zone during childhood, may lead to asymmetry or mandibular bilateral distortion, which is usually manifested in the second decade of life when the etiology is unknown to most people...

We demonstrate a dual usage of quanti ed facial asymmetry for (1) human identi cation under expression variations and (2) expression classi cation across di erent human subjects. Our experiments show the e ectiveness of using statistical bagging and feature subspace selection BEFORE applying classi ers such as Linear Discriminant Analysis. This preprocessing allows the same type but di erent di...

the silent sinus syndrome (sss) involves painless facial asymmetry and enophthalmos, which is theresult of chronic maxillary sinus atelectasis. in most cases, it is diagnosed clinically, however, usingthe characteristic imaging features including maxillary sinus outlet obstruction, sinus opacification,and sinus volume loss caused by inward retraction of the sinus walls. obstruction of the maxil...
