Some critics say Botox makes you lose all the personality from your face, leaving you with a significantly less range of motion when you laugh, or get angry or upset. While it’s true that your movement will be restricted, a moderate amount of Botox will still allow you to react and communicate in a lively way. “Botox relaxes the wrinkle-forming facial muscles at the sight of injection, such as crow’s feet, glabella (the ‘furrows’ in between the brows), and frontalis (forehead lines),” Dr. Waibel says. “Botox does not affect other facial muscles that are used for overall facial expressions.”
The FDA now requires black box labeling on Botox and similar products such as Dysport and Xeomin to warn of rare but potentially life-threatening swallowing and breathing complications if the toxin spreads beyond the injection site. None of these complications have occurred in people using Botox for cosmetic reasons and the FDA states that cosmetic use of Botox appears to be safe.
Ptosis generally occurs from injecting the frontalis incorrectly. The worst mistake is for the injector to move the procerus and corrugator injection points higher, where they will place more onabotulinumtoxinA into the frontalis. It is important to examine patients to determine their preexisting conditions prior to treatment administration. In particular, patients should be examined for pre-existing eyelid ptosis or pseudoptosis. With pseudoptosis, the lid strength is normal, but soft tissue covers part of the upper lid. With lid ptosis, the lid strength is weak. For both lid ptosis and pseudoptosis, patients will have frontalis compensatory activity, resulting in upgoing eyebrows (reverse Babinski sign). With brow ptosis, the frontalis is weak, and the eyebrow is depressed downward leading to tissue resting on the upper lid. To avoid this, the frontalis should be injected in the upper third of the forehead. The corrugator muscle attaches to bone at the medial end of the superciliary arch. The muscle fibers travel laterally and upward inserting into the skin in the middle of the supraorbital margin. The corrugator muscle is partially blended with the orbicularis oculi and occipitofrontalis. The supraorbital and supratrochlear nerves pass through the corrugator muscle. The corrugator muscle acts to pull the eyebrows downward and medially, which causes vertical wrinkle lines in the skin between the brows.
The patient’s neck stability, posture, torsion, and symmetry should be assessed to determine whether he or she may be at increased risk for adverse events prior to the first injection cycle. A patient with preexisting neck pain and/or weakness may be at higher risk for exacerbation of the condition upon injection of the occipitalis, cervical paraspinal, or trapezius muscle groups. Patients with smaller frames may be at higher risk for neck weakness. Indicated injection sites can still be injected with minimal side effects and unwanted outcomes as long as correct injection sites are targeted and treatments are administered using a superficial approach with avoidance of the mid and lower cervical regions. The cervical paraspinal muscle group is made up of multiple muscles including the trapezius, splenius capitis and cervicis, and semispinalis capitus. This group of muscles helps support the neck, including extension of the head.
BOTOX blocks neuromuscular transmission by binding to acceptor sites on motor or sympathetic nerve terminals, entering the nerve terminals, and inhibiting the release of acetylcholine. This inhibition occurs as the neurotoxin cleaves SNAP -25, a protein integral to the successful docking and release of acetylcholine from vesicles situated within nerve endings. When injected intramuscularly at therapeutic doses, BOTOX produces partial chemical denervation of the muscle resulting in a localized reduction in muscle act ivity. In addition, the muscle may atrophy, axonal sprouting may occur, and extrajunctional acetylcholine receptors may develop. There is evidence that reinnervation of the muscle may occur, thus slowly reversing muscle denervation produced by BOTOX.
As anyone who’s tried Botox for Migraine (or wrinkle reduction) will tell you, your forehead feels heavier after the injections are done, where the nerve endings are in essence frozen. As in ‘Frozen Face.’ Little to no movement, depending on how many units you receive and where they are injected. In my case, my usually expressive face didn’t track with my emotions: no raised eyebrows of surprise or delight or shock.
The most common side effect of the BOTOX procedure for migraines is neck pain. In clinical trials, 9 percent of patients reported this side effect. Other side effects can include headaches or muscle pain, but these side effects are far less common. If you do experience neck pain, an ice pack can help you manage the discomfort until it dissipates. At Allure Esthetic, we will perform the BOTOX for migraines procedure carefully and correctly.
Selecting the correct injection points is critical to the success of the procedure. These points are first scored with a marking pencil. Your doctor will likely select numerous injection points for each location to be treated. (These points are located where the muscle contracts — not necessarily at the wrinkle you are hoping to erase.) The Botox filler is then injected into the marked points beneath the skin.
The potency Units of BOTOX (onabotulinumtoxinA) for injection are specific to the preparation and assay method utilized. They are not interchangeable with other preparations of botulinum toxin products and, therefore, units of biological activity of BOTOX cannot be compared to nor converted into units of any other botulinum toxin products assessed with any other specific assay method [see WARNINGS AND PRECAUTIONS and DESCRIPTION] .
Botox is a neurotoxin derived from the bacterium Clostridium botulinum. Ingested in contaminated food, it can interfere with key muscles in the body, causing paralysis and even death. But when injected in tiny doses into targeted areas, it can block signals between nerves and muscles, causing the muscles to relax. That's how it smooths wrinkles: when you immobilize the muscles that surround fine lines, those lines are less likely to move--making them less noticeable. It's also why it's FDA-approved to treat an overactive bladder: Botox can prevent involuntary muscle contractions that can cause people to feel like they have to pee even when they don't.
A placebo-controlled, double-blind post-approval 52 week study with BOTOX 100 Units (Study NDO-3) was conducted in non-catheterizing MS patients with urinary incontinence due to detrusor overactivity associated with a neurologic condition. Catheterization for urinary retention was initiated in 15.2% (10/66) of patients following treatment with BOTOX 100 Units versus 2.6% (2/78) on placebo at any time during the complete treatment cycle. The median duration of post-injection catheterization for those who developed urinary retention was 64 days for BOTOX 100 Units and 2 days for placebo.
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.
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).
