The trapezius muscle is a large, triangular, superficial muscle. It attaches proximally in the medial third of the superior nuchal line, external occipital protuberance, nuchal ligament, and spinous processes of the C7-T12 vertebrae. Distal attachment of the trapezius occurs at the lateral third of the clavicle and acromion and spine of the scapula. The action of the muscle includes neck extension and stabilization of the scapula and support for the arm. The muscle fibers proximal to the inflection point of the neck (ie, necklace line) run vertically and are involved with neck extension. According to the PREEMPT injection paradigm, one injection of 5 units of onabotulinumtoxinA to each of three sites on either side of the trapezius, for a total of 30 units divided across six sites, is given. The first injection site can be identified by visually dividing the upper portion of the trapezius muscle in half, from the inflection point of the neck (ie the necklace line) to the acromion (acromio-clavicular joint); the midpoint of this location is where the injection should be administered. The second injection is located at the midpoint of the first injection site and the acromion. The third injection should be administered at the midpoint between the first injection site and the necklace line. Injections should occur in the supraclavicular portion of the muscle, lateral to the neckline, and medial to the deltoid and the acromio-clavicular joint. The injections into the trapezius should be administered horizontally and superficially to avoid injecting too deep.

Do not inject into blood vessels. Introduction of these products into the vasculature may lead to embolization, occlusion of the vessels, ischemia, or infarction. Take extra care when injecting soft-tissue fillers; for example, inject the product slowly and apply the least amount of pressure necessary. Rare, but serious, adverse events associated with the intravascular injection of soft-tissue fillers in the face have been reported and include temporary or permanent vision impairment, blindness, cerebral ischemia or cerebral hemorrhage leading to stroke, skin necrosis, and damage to underlying facial structures. Immediately stop the injection if a patient exhibits any of the following symptoms: changes in vision, signs of a stroke, blanching of the skin, unusual pain during or shortly after the procedure. Patients should receive prompt medical attention and, possibly, evaluation by an appropriate healthcare professional specialist should an intravascular injection occur
Autonomic dysreflexia in patients treated for overactive bladder due to neurologic disease. Autonomic dysreflexia associated with intradetrusor injections of BOTOX® could occur in patients treated for detrusor overactivity associated with a neurologic condition and may require prompt medical therapy. In clinical trials, the incidence of autonomic dysreflexia was greater in patients treated with BOTOX® 200 Units compared with placebo (1.5% versus 0.4%, respectively).
First of all, for those who aren't familiar with migraines, they're different from headaches. Headaches are unpleasant, too, but are typically less severe than migraines and don't usually present with other symptoms besides the pressure and aching in the head. Migraines, on the other hand, can be much more intense and often come with nausea, seeing spots, vomiting, extreme fatigue, sensitivity to light and sound, and more.
"Botox is a toxin that is extracted from a certain bacteria. It's been used for a couple of hundred years in medicine. It was first used in neurological conditions rather than cosmetic ones. It was first approved to treat spasms of the face and eye muscles. Only later was it discovered coincidentally that it could world for cosmetic purposes, like wrinkles," he says.
Side effects from cosmetic use generally result from unintended paralysis of facial muscles. These include partial facial paralysis, muscle weakness, and trouble swallowing. Side effects are not limited to direct paralysis however, and can also include headaches, flu-like symptoms, and allergic reactions. Just as cosmetic treatments only last a number of months, paralysis side-effects can have the same durations. At least in some cases, these effects are reported to dissipate in the weeks after treatment. Bruising at the site of injection is not a side effect of the toxin but rather of the mode of administration, and is reported as preventable if the clinician applies pressure to the injection site; when it occurs, it is reported in specific cases to last 7–11 days. When injecting the masseter muscle of the jaw, loss of muscle function can result in a loss or reduction of power to chew solid foods.
Scientists at the University of Granada have confirmed that injecting a local anesthetic or botulinum toxin (botox) into certain points named "trigger points" of the pericraneal and neck muscles reduce migraine frequency among migraine sufferers. University of Granada researchers have identified the location of these trigger points -which activation results in migraine- and their relationship with the duration and severity of this condition.
In Seattle, the cost usually ranges between 10$ and 16$ per unit. It varies depending on a few things. 1. Expertise of the injector, 2. Who the injector is (physician vs other), 3. Whether an office may be running a special. The number of units placed in an area can vary. For instance, for the frown lines between the eyebrows, studies show that the right amount for most women is 25 units. However, in my practice, I may put in as few as 10 (young female with a very petite forehead) or as many as 30 (larger forehead, strong frown line). We usually have 2-3 "botox" special events per year, and we also have an ongoing special price for VIP patients to reward them for coming to our clinic.
After a muscle has been injected, the nerves still send the signal to the muscle to contract, and the acetylcholine is still released, but is unable to bind to the muscle, resulting in a reduction of muscle activity and temporarily preventing contraction of the muscles that cause frown lines. The binding process typically begins within about 48 hours from the time it is injected into the muscle, and results typically become noticeable within 7 to 10 days. While results are often most noticeable in dynamic wrinkles (wrinkles that appear when a muscle contracts), it can also help soften wrinkles that are present even without muscle contraction. If you’re serious about improving the appearance of moderate to severe frown lines, it may be just the right treatment option for you.
It's a remarkable arc for a drug that only a few years ago was associated with Hollywood cocktail parties where guests came for Bellinis and left with a forehead full of Botox injections. It highlights the advances that can occur when physicians, seeking new therapies for their patients, explore creative new uses for approved drugs--basically, real-world experiments that take place largely beyond the reach of federal regulators. That, in turn, raises questions about the risks of deploying medicines in ways that have not been fully vetted. But it happens all the time.
