In challenging image acquisition settings where the performance of iris recognition algorithms degrades due to poor segmentation of the iris, image blur, specular reflections, and occlusions from eye lids and eye lashes, the periocular region has been shown to offer better recognition rates. However, the definition of a periocular region is subject to interpretation. This paper investigates the...

BACKGROUND Recently developed endoscopic brow-lifting techniques and instrumentation are being used for treatment of anterior table frontal sinus fractures. Potential endoscopic treatment options include fracture reduction with or without plating and fracture repair with hydroxyapatite bone cement (HA). OBJECTIVE To evaluate the efficacy of miniplates and HA for repair of anterior table fract...

IMPORTANCE To improve preoperative counseling for patients considering endoscopic brow-lift (EBL). OBJECTIVES To understand patient-reported outcomes, satisfaction, and recovery after EBL surgery to improve preoperative counseling. DESIGN, SETTING, AND PARTICIPANTS A retrospective telephone survey of 57 patients who had EBL or EBL with concurrent rhytidectomy to assess cosmetic and function...

The face is a rich source of information about human behavior. Available methods for coding facial displays, however, are human-observer dependent, labor intensive, and difficult to standardize. To enable rigorous and efficient quantitative measurement of facial displays, we have developed an automated method of facial display analysis. In this report, we compare the results with this automated...

In the present study we modified the standard classification image method by subsampling visual stimuli to provide us with a technique capable of examining an individual's face-processing strategy in detail with fewer trials. Experiment 1 confirmed that one testing session (1450 trials) was sufficient to produce classification images that were qualitatively similar to those obtained previously ...

INTRODUCTION Surgical management of the frontal sinus is more complex compared to the other sinuses. Testament to this fact is that for years the standard for refractory frontal disease has been the destructive procedure of an osteoplastic flap with complete obliteration of the sinus. With better understanding of the physiology of the paranasal sinuses, there has been a shift toward surgery dir...

BACKGROUND The horns and frill of Triceratops and other ceratopsids (horned dinosaurs) are interpreted variously as display structures or as weapons against conspecifics and predators. Lesions (in the form of periosteal reactive bone, healing fractures, and alleged punctures) on Triceratops skulls have been used as anecdotal support of intraspecific combat similar to that in modern horned and a...

Seventeen patients averaging 51 years of age underwent 23 surgical procedures, including suture suspension for both midface and neck rejuvenations. A 3/0 polypropylene thread with bioabsorbable cones with multiple point fixations in addition to 2 x 0.5-cm polypropylene surgical mesh are used in this technique. The mean postoperative, follow-up time was 9 months. Of the 17 patients, 12 underwent...

OBJECTIVES To evaluate a novel 3-D geometry video acquisition system (3-D VAS) for quantifying facial movement. METHODS Ten normal subjects and four patients with facial paralysis underwent recording of facial movement during three facial expressions. Facial feature points of interest were digitally marked on selected images. The maximum 3-D displacement of the brow and oral commissure and pa...

Because alternatives exist for the full facelift (rhytidectomy), this procedure has become less popular overtime. In the past, forehead wrinkles were addressed with coronal[1,2] and endoscopically assisted forehead lift[3] procedures. Today, botulinum toxin and hyaluronic acid fillers are used for this purpose because they are more effective and result in less downtime. Lateral brow sag can be ...
