A 32-year-old man presented with atypical left hemifacial spasm (HFS) with MRI showing compression of left facial nerve at the root exit zone. HFS rarely presents atypically with onset in orbicularis oris and later spreading upward to involve the orbicularis oculi as was seen in our case. Atypical presentation of hemifacial spasm is rare and vertebral artery dolichoectasia as the underlying aet...

Botulinum toxin was used to treat senile entropion in 12 patients by injection into the preseptal orbicularis muscle of the lower lids. It produced relief of symptoms in 10 patients but this was transient, lasting for an average of 14.8 weeks before orbicularis function returned. The technique is simple and easy to perform, and may be useful in selected patients, but surgery offers a more perma...

OBJECTIVES To construct a computer assisted information system for the estimation of the numbers of workers exposed to established and suspected human carcinogens in the member states of the European Union (EU). METHODS A database called CAREX (carcinogen exposure) was designed to provide selected exposure data and documented estimates of the number of workers exposed to carcinogens by countr...

Eyelid bags and blepharochalasis are the result of relaxation of lid structures like the skin, the orbicularis oculi, and mainly the orbital septum. Therefore, this aged appearance cannot be improved sufficiently with only a skin and orbicularis oculi resection. To improve this appearance, we use a very effective method of tucking of the orbital septum with infraeyebrow excision of the skin and...

Bilateral cleft lip repairs can result in various secondary deformities. One more commonly seen deformity, the whistle deformity, is characterized by a reduced or absent tubercle, orbicularis muscle diastasis, and abnormalities of the philtrum with notched appearance of cupid's bow. Various techniques have been described to address these problems. One common procedure is the lip-switch flap ori...

BACKGROUND AND AIMS The sedge genus Carex, the most diversified angiosperm genus of the northern temperate zone, is renowned for its holocentric chromosomes and karyotype variability. The genus exhibits high variation in chromosome numbers both among and within species. Despite the possibility that this chromosome evolution may play a role in the high species diversity of Carex, population-leve...

[1] We conducted measurements of methane (CH4) emission and ecosystem respiration on >200 points across the Arctic coastal tundra near Barrow, Alaska, United States, in July 2007 and August 2008. This site contains broad diversity in tundra microtopography, including polygonal tundra, thaw lakes, and drained lake basins. In 2007, we surveyed CH4 emissions across this landscape, and found that s...

Monoecy and protogyny are widespread in wind-pollinated plants and have been interpreted as outcrossing mechanisms, though few studies have investigated their function. Carex, a large genus of anemophilous herbs, is predominantly monoecious and many species are protogynous. We investigated whether monoecy and protogyny limit self-pollination in seven Carex species. We conducted field experiment...

the cutaneous approach, whether it is for blepharoplasty, orbital surgery, or eyelid rotation, relates to the orbicularis septal complex. Hematoma, inflammation, and scarring in this middle lamellar plane can result in eyelid retraction or volume deflation. Lower eyelid entropion surgeries accomplish their anatomic goal by creating a scar between the lower eyelid retractors and the anterior tar...

PURPOSE To clarify anatomically the facial nerve branches in the eyelids and periorbit. METHODS The facial nerve branches of the left periorbits from 31 Japanese cadavers were dissected under a surgical microscope. RESULTS The temporal, zygomatic, and deep buccal branches assembled posterior to the orbicularis oculi from its temporal or inferior side, and formed a dense plexus. The superfic...
