Botulinum toxin A effectively treats mentalis muscle dysfunction after failed chin augmentation surgery. This temporary treatment improves appearance and function, offering a safe option for patients experiencing post-mentoplasty complications.

Area of Science:

  • Facial Plastic Surgery
  • Neuromodulation
  • Aesthetic Medicine

Background:

  • Failed augmentation mentoplasty can lead to mentalis muscle dysfunction.
  • Complications include mental skin dimpling and soft tissue ptosis.

Purpose of the Study:

  • To evaluate botulinum toxin A as a treatment for mentalis muscle dysfunction.
  • To assess outcomes in patients with secondary complications from failed mentoplasty.

Main Methods:

  • Clinical observations in a private facial plastic surgery practice.
  • Treatment involved 20 U of botulinum toxin A injection.
  • Assessment included photographic documentation and patient satisfaction surveys.

Main Results:

  • All three patients reported improved appearance and alleviation of mentalis dysfunction.
  • Symptom recurrence correlated with the waning effects of botulinum toxin A.
  • Photographic and survey data supported functional and aesthetic improvements.

    • Conclusions:

    • Botulinum toxin A is a safe and effective temporary treatment for mentalis muscle dysfunction.
    • The treatment offers predictable results for complications arising from failed augmentation mentoplasty.
