Outcome Measures

Primary Outcomes (1)

  • Metric masseteric hypertrophy improvement outcomes between SIT and MIT at 16 weeks in comparison to baseline.

    The difference in physician assessed efficacy using standardized masseter improvement measurements between two different injection techniques at 16 weeks (visit 4) in comparison to baseline (visit 2).

    Baseline to 16 weeks

Secondary Outcomes (3)

  • Masseter photo-numeric aesthetic rating scales between SIT and MIT at 16 weeks in comparison to baseline.

    Baseline to 16 weeks

  • Patient Satisfaction Questionnaire

    Baseline to 20 weeks

  • Global Aesthetic Improvement Scale

    Baseline to 20 weeks

Other Outcomes (1)

  • Adverse Events

    Baseline to 20 weeks

Study Arms (2)

single injection technique (SIT)

EXPERIMENTAL

40 U of Xeomin Cosmetic delivered directly into the region where the three masseter heads overlap.

Device: Xeomin Cosmetic

multi-injection technique (MIT)

EXPERIMENTAL

A distribution of 40 U (8 U distributed in 5 different areas) of Xeomin Cosmetic over the width of the masseter while respecting the upper limit of the anterior border of the masseter and the inferior insertion of the masseter. The injections are separated by a 1cm distance and the dose is equally distributed across these sites.

Device: Xeomin Cosmetic

Interventions

Xeomin Cosmetic is the purest commercially available botulinum toxin type A available to date. It has been approved by Health Canada since 2012 for the temporary improvement in the appearance of moderate to severe glabellar lines.
