    Muscles for Facial Expressions

    The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

    This study introduces a triangular Botox injection pattern for effective forehead wrinkle correction. This method minimizes risks like brow ptosis and allows adjustable preservation of facial expressions.

    Area of Science:

    • Plastic Surgery
    • Dermatology
    • Neurology

    Background:

    • Forehead wrinkles are a common aesthetic concern.
    • Botulinum toxin injections are a popular treatment for dynamic and static wrinkles.
    • Current injection techniques carry risks such as brow and eyelid ptosis.

    Purpose of the Study:

    • To present a novel triangular injection pattern for botulinum toxin type A (Botox) administration.
    • To evaluate the efficacy and safety of this technique for forehead wrinkle correction.
    • To assess the technique's ability to preserve or alter mimetic function.

    Main Methods:

    • A specific triangular pattern for Botox administration in the forehead was employed.
    • Dosage and injection techniques were varied to assess impact on function.

    Published on: March 1, 2015

  • Correction of static and dynamic wrinkles was evaluated.
  • Incidence of brow and upper lid ptosis was monitored.

    • Main Results:

    • The triangular Botox pattern demonstrated reproducible correction of forehead wrinkles.
    • The technique was associated with minimal risk of brow and upper lid ptosis.
    • Adjustable preservation or obliteration of mimetic function was achieved by varying dosage and technique.

    Conclusions:

    • The triangular Botox administration pattern offers a safe and effective method for forehead rejuvenation.
    • This technique provides predictable results with a low risk of complications.
    • It allows for tailored outcomes regarding facial expression preservation.
