Eye contact often elicits a smiling response. We investigated whether an individual’s awareness that the recipient perceives their direct gaze during eye has influence on this Participants wore glasses with either clear or dark lenses (preventing other person from seeing eyes). Measurements of electromyographic activity zygomatic and periocular muscle regions showed responses were greater to ot...

Dental rehabilitation of a completely edentulous geriatric patient has always been a challenge to the clinician, especially in treating those with higher expectations and demands. Treatment duration and the amount of residual alveolar bone available are often important considerations when planning for dental implant-based fixed treatment for these patients. With the introduction of zygomatic im...

The restoration of extensive zygomatic complex defects is a surgical challenge owing to the difficulty of accurately restoring the normal anatomy, symmetry, proper facial projection and facial width. In the present study, an extensive post-traumatic zygomatic bone defect was reconstructed using a custom-made implant that was made with a selective laser melting (SLM) technique. The computer-desi...

BACKGROUND Posterior clinoid process (PCP) meningiomas are rare lesions. In close proximity to these lesions are the perforators from internal carotid artery and the oculomotor nerve, which need to be considered while deciding the appropriate surgical approach. CASE DESCRIPTION We describe a basal frontotemporo-orbito-zygomatic approach with splitting of the sylvian fissure to resect an eccen...

Facial reactions in schizophrenic patients were assessed via electromyography (EMG) in response to pictures of facial expressions. Male patients and nonpatient controls viewed photographs of positive and negative facial expressions while EMG activity from the corrugator and zygomatic muscle regions was recorded. Both schizophrenic patients and controls exhibited greater zygomatic reactivity in ...

The suggestion that dynamic facial expressions of emotion induce more evident facial mimicry than static ones remains controversial. We investigated this issue by recording EMG from the corrugator supercilii and zygomatic major. Dynamic and static facial expressions of anger and happiness were presented. Dynamic presentations of angry expressions induced stronger EMG activity from the corrugato...

desmoplastic fibroma (df) is a rare and locally aggressive intraosseous tumor with unknown etiology. the mandible is the common site of involvement in the maxillofacial region. however, it is believed that df can arise in any bone of the body. a wide age distribution has been reported for df occurrence, extending from birth to the sixth decade of life, with a peak incidence at 10 to 19 years of...

Fractures of the zygomatic complex and their treatment have been the focus of much attention in the last 30 years. Treatment frequently depends on the surgical findings, experience, and discretion of the surgeon. Treatment of zygomatic complex (ZMC) fractures often requires stabilization at the frontozygomatic (FZ) suture. Frodel’ and Marentette’ have described the use of lag screw fixation of ...

The Brånemark Zygomaticus implant was used in conjunction with premaxillary standard implants for the reconstruction of resorbed edentulous maxillae. A total of 44 zygomatic implants and 80 premaxillary implants were placed in 22 patients. All implants were stabilized at phase II surgery using a rigid bar. After soft tissues had healed, implant-supported fixed prostheses were fabricated. This a...
