The frontalis muscle attaches to the skin of the lower forehead and ascends to join the fronto-occipital aponeurosis. The action of the frontalis muscle involves elevation of the eyebrows to produce expressions such as surprise, and can cause deep transverse wrinkles on the forehead. The antagonists for brow depression are the corrugators, procerus, and orbicularis oculi muscles.
The initial listed doses of the reconstituted BOTOX [see Preparation And Dilution Technique] typically create paralysis of the injected muscles beginning one to two days after injection and increasing in intensity during the first week. The paralysis lasts for 2-6 weeks and gradually resolves over a similar time period. Overcorrections lasting over six months have been rare. About one half of patients will require subsequent doses because of inadequate paralytic response of the muscle to the initial dose, or because of mechanical factors such as large deviations or restrictions, or because of the lack of binocular motor fusion to stabilize the alignment .
A BOTOX “treatment” consists of 31 injections to the head and neck areas, if adherence to the FDA approved protocol is followed. Except for injection into the procerus, which is in the midline, all others are paired sets of injections on the left and right sides. Muscles included are the frontalis and temporalis areas as well as the occipitalis, upper cervical paraspinals, and trapezii. The amount injected at each of the 31 injection sites is small—5 units of BOTOX in a volume of 0.1 mL normal saline or sterile water. A total of 155 units is are typically used.
“Botox is a completely cosmetic procedure, so if and when someone ‘needs’ it is a purely personal decision,” Shah says. “Some people are not bothered by developing fine lines and wrinkles. For those who are, I generally advise starting treatments just when they start to see the lines develop, or when the wrinkles linger even after the movement has stopped.”
I had no idea my health insurance could take Botox away from me. I checked Cigna’s policy and found out that in order to continue receiving Botox coverage after one year, I need to get at least seven fewer migraine days — or at least 100 fewer migraine hours — per month compared to pre-Botox treatments. (I keep a diary to record when I have migraines.) Worse still, if I were to change my job — and therefore change my health insurance — my new insurance could ask me to run through the cheap medication gauntlet again before covering Botox.
A recent encounter with one of my headache patients got me thinking. I am treating this young woman for chronic migraine with BOTOX injections. She told me that one of her other physicians had been surprised to hear about this use for onabotulinumtoxin A. According to my patient, the gastroenterologist’s words were, “BOTOX for migraines? I’ve never heard of that.”
Although one cannot predict exactly who will respond, I find that those patients who are going to respond will note some improvement in headaches following the first set of injections. Repeat injection sets can be performed on the same patient no sooner than every 3 months, as long as a benefit is seen. Most insurers require that you document at least a 50% improvement in the chronic migraine frequency and/or severity for continued coverage. I usually recommend that my migraine patients have a second set of injections before deciding that this treatment modality is of no benefit to them.
Study responders were defined as patients who showed at least a 2-grade improvement from baseline value on the HDSS 4 weeks after both of the first two treatment sessions or had a sustained response after their first treatment session and did not receive re-treatment during the study. Spontaneous resting axillary sweat production was assessed by weighing a filter paper held in the axilla ov er a period of 5 minutes (gravimetric measurement). Sweat production responders were those patients who demonstrated a reduction in axillary sweating from baseline of at least 50% at week 4.
Dermal fillers, as we’ve discussed in our previous post, vary on what you’re looking for and how long you’d like to see those results. According to the Plastic Surgeons Portal, the minimum you’ll pay for dermal fillers, like Juvederm and Restylane, is going to $1500, while the maximum you’re looking at is $2,500. It’s a small price to pay for radiance and confidence!
The recommended dilution is 200 Units/2 mL, 200 Units/4 mL, 100 Units/1 mL, or 100 Units/2 mL with preservative-free 0.9% Sodium Chloride Injection, USP, depending on volume and number of injection sites desired to achieve treatment objectives (see Table 1). In general, no more than 50 Units per site should be administered using a sterile needle (e.g., 25-30 gauge) of an appropriate length. Localization of the involved muscles with electromyographic guidance may be useful.
Khalaf Bushara and David Park were the first to demonstrate a nonmuscular use of BTX-A while treating patients with hemifacial spasm in England in 1993, showing that botulinum toxin injections inhibit sweating, and so are useful in treating hyperhidrosis (excessive sweating). BTX-A has since been approved for the treatment of severe primary axillary hyperhidrosis (excessive underarm sweating of unknown cause), which cannot be managed by topical agents.
I had a consult and the doctor quickly realized that I was a candidate for Botox. He ordered an MRI and doppler of my brain to make sure everything else was A-OK, and then the rest was just waiting on my insurance company. With Botox (I’m not sure if it’s all Botox or just prescription), the insurance company orders it from a pharmacy and sends it to the doctor.
The cost of a Botox treatment is usually communicated as a flat cost, but can also be measured in individual injectable units. Each unit usually costs somewhere in the neighborhood of $15, but prices vary between geographic areas and between individual clinics. How many units are needed per treatment will depend on which areas of your face are being treated, and on your individual facial anatomy.
Food-borne botulism results, indirectly, from ingestion of food contaminated with Clostridium spores, where exposure to an anaerobic environment allows the spores to germinate, after which the bacteria can multiply and produce toxin. Critically, it is ingestion of toxin rather than spores or vegetative bacteria that causes botulism. Botulism is nevertheless known to be transmitted through canned foods not cooked correctly before canning or after can opening, and so is preventable. Infant botulism cases arise chiefly as a result of environmental exposure and are therefore more difficult to prevent. Infant botulism arising from consumption of honey can be prevented by eliminating honey from diets of children less than 12 months old.
In general, adverse reactions occur within the first week follo wing injection of BOTOX and while generally transient, may have a duration of several months or longer. Localized pain, infection, inflammation, tenderness, swelling, erythema, and/or bleeding/bruising may be associated with the injection. Needle-related pain and/or anxiety may result in vasovagal responses (including e.g., syncope, hypotension), which may require appropriate medical therapy.
After an exam by a therapist and doctor, botulinum toxin for focal relief of muscle spasticity can be advised as the best way to address a child's functional problems. The problem muscle groups are identified, and goals for that child are discussed. Then the injection of botulinum toxin can be done if there are no permanent contractures of the muscle groups.
The ideal needle to use is a 30G or 31G, half-inch needle. Longer needles are problematic as they encourage deeper injections, which can increase the risk of muscle weakness, and most of the side effects such as neck pain stem from muscle weakness. Perseverative-free normal saline is the only diluent that should be used. There is a case study of a patient who died when onabotulinumtoxinA was mixed with a local anesthetic agent. The pivotal trial established an effective dose using 2 mL/100 units of onabotulinumtoxinA. A fact that is often overlooked is that the mean dose in the trial was 165 units. The patients all received 155 units with a fixed dose, fixed-site injection protocol, and an option of an additional 40 units to follow the pain. This resulted in a mean dose of 165 units, which is the standard that should be used to achieve the efficacy results reviewed above.
In 1986, Oculinum Inc, Scott's micromanufacturer and distributor of botulinum toxin, was unable to obtain product liability insurance, and could no longer supply the drug. As supplies became exhausted, patients who had come to rely on periodic injections became desperate. For 4 months, as liability issues were resolved, American blepharospasm patients traveled to Canadian eye centers for their injections.
The safe and effective use of BOTOX depends upon proper storage of the product, selection of the correct dose, and proper reconstitution and administration techniques. An understanding of standard electromyographic techniques is also required for treatment of strabismus, upper or lower limb spasticity, and may be useful for the treatment of cervical dystonia. Physicians administering BOTOX must understand the relevant neuromuscular and structural anatomy of the area involved and any alterations to the anatomy due to prior surgical procedures and disease, especially when injecting near the lungs.
