What is the primary muscle targeted during botulinum toxin treatment for a puckered chin?
The primary muscle targeted during botulinum toxin treatment for a puckered chin is the mentalis muscle.
The mentalis muscle is responsible for the puckered or cobblestoned appearance of the chin. Botulinum toxin treatment targets this muscle to inhibit its contraction, which smoothes the chin surface and reduces the appearance of a dynamic mental crease. The mentalis muscle is a deep, two-bellied muscle with superficial attachments to the skin, and its contraction causes the textural changes associated with a puckered chin.
Key points
- The mentalis muscle is targeted for treating a puckered chin with botulinum toxin.
- Contraction of the mentalis muscle causes a puckered or cobblestoned chin appearance.
- Botulinum toxin inhibits mentalis muscle contraction, smoothing the chin.
- The mentalis muscle is deep with superficial skin attachments, affecting chin texture.
