Summary
Botulinum toxin A injections near the eye can cause festooning, a rare complication. Caution is advised for patients with prior lower eyelid surgery due to potential muscle weakening.
Area of Science:
- Oculoplastics
- Cosmetic Dermatology
- Facial Anatomy
Background:
- Lateral canthus and infraorbital fold injections are common cosmetic procedures.
- These injections aim to reduce wrinkles and enhance eye appearance.
Observation:
- A case report details a 56-year-old male experiencing infraocular festooning.
- Festooning occurred post-botulinum toxin A injection.
Findings:
- Prior lower lid blepharoplasty may weaken the infraorbital orbicularis oculi muscle.
- Botulinum toxin A injection further compromised the already weakened muscle, leading to festooning.
Implications:
- Exercise caution with infraocular botulinum toxin A injections in patients with a history of blepharoplasty.
- Understanding pre-existing muscle status is crucial for preventing adverse outcomes.
