Summary

This study introduces a dynamic, functional approach to botulinum toxin type A (BoNT-A) injections for facial rejuvenation. Tailored injection techniques optimize brow elevation and reduce wrinkles for personalized aesthetic outcomes.

Area of Science:

  • Aesthetic Medicine
  • Neuromodulation
  • Facial Anatomy

Context:

  • Traditional facial analysis for botulinum toxin type A (BoNT-A) injections focuses on static assessment.
  • Dynamic, functional facial analysis offers a more nuanced understanding of muscle interactions.
  • Palpation during dynamic assessment aids in precise treatment planning.

Purpose:

  • To demonstrate the value of dynamic, functional facial analysis over static assessment for BoNT-A injections.
  • To introduce novel injection techniques for specific facial muscles, including the frontalis, procerus, corrugator, and orbicularis oculi.
  • To achieve targeted aesthetic outcomes such as brow elevation and wrinkle reduction.

Summary:

  • A new functional segmentation of the frontalis muscle is described to prioritize brow elevation over complete wrinkle eradication.
  • The antagonistic role of the procerus muscle to the frontalis is explained, guiding targeted injections.
  • Specific techniques for injecting the lateral corrugator muscle enhance eyebrow elevation while minimizing risks to adjacent muscles.
  • Precise injection points along the lateral orbital rim are detailed for eyebrow tail elevation and crow's foot reduction, avoiding ocular muscle migration.
  • Treatment of the tear trough is addressed via injection of the orbicularis oculi muscle.
  • This functional approach allows for personalized, 'haute couture' BoNT-A treatments.

Impact:

  • Shifts BoNT-A injection methodology from a standardized approach to a highly individualized, patient-specific strategy.
  • Enhances the precision and safety of facial rejuvenation procedures using BoNT-A.
  • Improves aesthetic results by optimizing the functional interplay of facial muscles.
