First Complication with Dysport--But is it Dysport's Fault?
Ms. LM has suffered the first significant complication that I have ever had with an injectable botulinum neurotoxin (i.e., Botox or Dysport)--ptosis, or drooping of the upper eyelid.
Ms. LM is just 48 years old, and she has been a faithful Botox patient in my Ventura, California, office for over two years. She has loved...
- fewer wrinkles at the glabella (between the eyebrows)
- softer crow's feet
- reduced bunny lines (on the sides of the nose)
- elevated eyebrows, with more arch
Despite her youth, Ms. LM has not always been healthy. She had suffered a stroke 5 years ago, which had temporarily paralyzed her entire left side, including her face, arm, and leg. Although she has recovered nearly completely, she has admitted to persistent left-sided weakness.
Quarterly Botox has always been terrific, and has never resulted in an untoward effect. However, this past session, I used the other botulinum neurotoxin type A--Dysport.
Two weeks later, she definitely has a left upper eyelid ptosis--a drooping of the left upper eyelid.
- Ptosis is a known complication of both Botox and Dysport.
- According to most research studies, ptosis occurs in 1-5% of patients.
- However, none of my patients have ever suffered such a complication before. And I have injected Botox thousands of times.
- Is Ms. LM at particular risk for ptosis because of the stroke and the residual left-sided weakness?
- Then, why didn't Botox unmask the problem? Why was it Dysport that led to the ptosis?
- Does Dysport "spread" too much? Is it uncontrollable?
- A single case does not create rule. However, should I temper my enthusiasm for Dysport?
For now, I have prescribed an eye drop that will minimize the drooping, and I will wait patiently with Ms. LM. Supposedly, the eyelid will be droopy for 2-6 weeks, rather the full 12-16 weeks that the botulinum neurotoxin type A will be effective elsewhere. In the future, at least in her case, I will use Botox rather than Dysport.
