Botulinum toxin A for mentalis muscle dysfunction.
OBJECTIVE
To describe the use of botulinum toxin A for treatment of mentalis muscle dysfunction secondary to failed augmentation mentoplasty.


METHODS
Clinical observations were made in the treatment of mentalis muscle dysfunction. Patients with the postmentoplasty signs of mental skin dimpling and soft tissue ptosis were injected with 20 U of botulinum toxin A and observed for visual and functional improvement. Photographs were taken for documentation.


METHODS
Private facial plastic surgery practice.


METHODS
Three patients with a history of failed augmentation mentoplasty were identified and signs/symptoms recorded. Each patient was treated with 20 U of botulinum toxin A and observed for clinical improvement.


METHODS
Pretreatment and posttreatment photographs of active and passive mentalis function together with patient satisfaction surveys.


RESULTS
Of the 3 patients treated, all reported alleviation of the mentalis dysfunction and improved appearance. The symptoms began to return as the botulinum toxin A effects subsided.


CONCLUSIONS
Botulinum toxin A is a safe and effective treatment of mentalis dysfunction secondary to failed augmentation mentoplasty. The effects are predictable, although temporary.
