Eyelid drooping, or ptosis, is a potential complication following botulinum toxin injections in the upper face. This undesirable outcome arises from the unintended diffusion of the neurotoxin, affecting the levator palpebrae superioris muscle, which is responsible for elevating the upper eyelid. The severity can vary, ranging from subtle asymmetry to significant visual impairment. Careful injection technique is paramount to minimizing this risk. An example of avoiding this is to maintain a safe distance from the orbital rim when administering injections in the glabellar region.
Preventing post-injection ptosis is crucial for maintaining patient satisfaction and achieving desired aesthetic outcomes. Its avoidance preserves the natural appearance and visual field, contributing to a positive experience with botulinum toxin treatments. Historically, understanding the facial anatomy and proper injection methods has evolved, leading to refined techniques and a reduced incidence of this adverse event. Mastery of these techniques enhances the safety profile and efficacy of botulinum toxin procedures.
