Misconceptions with Botulinum ToxinTypical Conversation with Clients
• But it’s a Toxin! That means it’s a poisonous!
• I’ve read / heard about this person who ….
• I thought you were (just) an Ophthalmologist…
• But its only temporary…

History of Botulinum toxin
1895
Prof Emile Pierre Marie van Ermengen identified C. botulinum
1946Dr Edward Schantz isolated pure BoNT/A in crystalline form
1953
1980
Dr Vernon Brooks showed that BoNT blocked the release of acetylcholine from motor nerve endings
1989
1992
Dr Alan Scott demonstrated the safety and efficacy of BoNT/A in humans (strabismus)
Drs. Jean and Alistair Carruthers published the first paper on the use of BOTOX® for cosmetic purposes
2002
Allergan introduced BOTOX®, the first BoNT/A approved by US FDA for blepharospasm &strabismus
BOTOX® gained US FDA approval for glabellarlines
1817-22
Dr Justinus Kerner published a complete description of food-borne botulism (sausage poison)

Botulinum Toxin(BTX)• A powerful neurotoxin
• Produced by Clostridium botulinum, an anaerobic, Gram-positive, spore-forming bacillus
• Causes acute flaccid paralysis

BTX Serotypes
8 Serotypes: A, B, C1, C2, D, E, F, G
Antigenically and serologically distinct butstructurally similar
A – most potent
A, B – used clinically
A, B, E – commonly associated with human botulism

Wrinkling Pattern In Aging
• The wrinkling pattern of the aging face follows naturally occurring creases, and are caused by habitual contraction of facial muscles
• Facial lines are generally perpendicular to the orientation of the underlying muscle fibers

Storage of Botulinum Toxin
• 85 patients (19 to 79 years of age) with glabellar frown lines were treated with reconstituted BOTOX® for periods of time ranging from 1 day to 6 weeks.
• Muscle motility and presence of wrinkles were evaluated up to 60 days post-treatment
BOTOX® may be applied up to 6 weeks after reconstitution without losing its effectiveness

Side Effects andComplications
J Am Acad Dermatol 2009;61:961-70.
Side effects are usually mild and transient and most commonly include swelling or bruising at the injection site, mild headache, or flu-like symptoms
Botulinum toxin is relatively safe and well-tolerated with the following: APPROPRIATE PATIENT SELECTION
PROPER DOSINGINJECTION TECHNIQUES

Immunogenicity
• 11/2,240 subjects (0.49%) exhibited seroconversion
• 3 subjects became clinically unresponsive to onabotulinumtoxinA
The presence of neutralizing antibodies does not always predictnon-response to Botox treatment
Botox contains a protein product that can elicit antibody formation
![Page 77: Periorbital Applications of BotulinumToxin · Prof Emile Pierre Marie van Ermengen identified C. botulinum 1946 Dr Edward Schantz isolated pure BoNT/A in crystallineform 1953 1980](https://reader033.vdocuments.mx/reader033/viewer/2022042217/5ec174e3f7cde622c528f9d0/html5/thumbnails/77.jpg)
Immunogenicity
Risk Factors:
• Injection of >200 units per session
• Repeat or booster injections given within 1 month of treatment
Carruthers J, Carruthers A. Overview of botulinum toxin for cosmetic indications. In: UpToDate, Dover JS , Ofori AO (Eds), UpToDate, Waltham, MA, 2017. Nigam PK, Nigam A. Botulinum toxin. Indian J Dermatol 2010;55:8-14.

IncobotulinumtoxinA’s immunogenicity may be different from OnabotulinumtoxinA and AbobotulinumtoxinA that of since it is free from
complexing proteins
Injecting the lowest effective doses, with the longest feasible intervals between injections, may minimize the risk for immunogenicity
![Page 78: Periorbital Applications of BotulinumToxin · Prof Emile Pierre Marie van Ermengen identified C. botulinum 1946 Dr Edward Schantz isolated pure BoNT/A in crystallineform 1953 1980](https://reader033.vdocuments.mx/reader033/viewer/2022042217/5ec174e3f7cde622c528f9d0/html5/thumbnails/78.jpg)
Conclusion• Botulinum toxin A is safe and effective in treating
involuntary muscle action of Blepharospasm & Hemifacial spasm
• Botumlinum toxin A is safe and effective in achieving facial rejuvenation and enhancement
• A thorough understanding of facial anatomy and injection techniques, as well as proper dilution and storage, are essential to a successful outcome without complications.
