The focal dystonia benign essential blepharospasm (BEB) affects as many as 40,000 individuals in the United States. This dystonia is characterized by trigeminal hyperexcitability, photophobia, and most disabling of the symptoms, involuntary spasms of lid closure that can produce functional blindness. Like many focal dystonias, BEB appears to develop from the interaction between a predisposing c...

While the principles of eyelid reconstruction are well-established, achieving good functional and aesthetic reconstruction remains challenging. This communication presents a technique that we used on a young patient with an eyelid defect following a thermal burn. The patient was operated on to reconstruct the entire upper eyelid using, as a posterior lamella, a mucochondrial autologous graft ta...

The blink reflex latencies and cephalometric indexes were analysed in 30 male volunteers from three different races, 10 white, 10 black, and 10 Oriental. Ages ranged from 15 to 59 years, height from 1,60 to 1,80 m, and weight from 60 to 80 kg. Blink reflexes were obtained after unilateral electric stimulation of the supraorbital nerve for quantitative analysis of 3 responses, early ipsilateral ...

The architecture and musculotopic organization of the facial motor nucleus in the Cebus apella monkey (a New World primate) were investigated using histological techniques and a multiple labelling strategy, in which horseradish peroxidase-conjugated neuroanatomical tracers (CTB-HRP and WGA-HRP) and fluorescent tracers were injected into individual facial muscles. The facial motor nucleus was fo...

BACKGROUND The ability to correct unnatural-appearing, high, and deep double eyelid folds has been limited by the lack of redundant upper eyelid skin and the presence of prior incision line scars in patients. METHODS From January 2000 to September 2011, 256 patients with high and deep double eyelid folds underwent our fold-lowering procedure. The first dissection was made at the superficial l...

The zygomaticofacial branch (ZFb) of the zygomatic nerve travels along the inferolateral angle of the orbit, traverses the zygomaticofacial foramen (ZFF) in the zygomatic bone, and then perforates the orbicularis oculi muscle to finally reach the skin of the malar area, which it innervates. The bilateral absence of the ZFb and the ZFF was found in an 80-year-old Caucasian cadaver. In addition, ...

BACKGROUND Infraorbital dark circles refer to the conditions that present with darkness of the infraorbital eyelids. Although it is not a medical concern, it can be a cosmetic concern for a large number of individuals. Moreover, clear definition and possible causes have not been elucidated. OBJECTIVE To review the possible causes and treatment options for infraorbital dark circles. METHODS ...

The authors examined phasic psychophysiological responses indexing emotional valence and arousal to different game events during the video game Monkey Bowling 2. Event-related changes in skin conductance, cardiac interbeat intervals, and facial EMG activity over corrugator supercilii, zygomaticus major, and orbicularis oculi were recorded. Game events elicited reliable valenceand arousal-relate...

Arq Neuropsiquiatr 2012;70(8):637-644 640 We also highlight the fact that this unusual presentation of dystonia is almost indistinguishable from essential BSM, except by the non-involvement of the orbicularis oculi muscles. To best of our knowledge, this is the first report of sole frontalis, corrugator and procerus dystonia. Recently, Hirota et al.5 reported two cases of dystonic frowning. The...

Facial self-resemblance has been associated with positive emotional evaluations, but this effect may be biased by self-face familiarity. Here we report two experiments utilizing startle modulation to investigate how the processing of facial expressions of emotion is affected by subtle resemblance to the self as well as to familiar faces. Participants of the first experiment (I) (N = 39) were pr...
