Overview
The mentalis muscle originates as a bi-lobed muscle from the mandible directly below the labiomental crease. Despite having only two small circular bony attachments, this muscle fuses and forms a large 3-dimentional network of muscles fibers before inserting into the skin of the chin zone. When the mentalis muscle contracts, the mental soft tissue elevate, the lower lip everts, and skin surface irregularities also termed chinullite (cellulite of the chin) can be observed. This video provides a comprehensive overview of the functional anatomy of the mentalis muscle and although no injection simulations are performed, this video is best suited for briefly freshen up on chin anatomy prior to clinical treatments.
