Depth of Botulinum Neurotoxin Injection for Treatment of Glabellar Lines
Sponsor: Henry Ford Health System
Summary
STUDY QUESTION: Does the depth of injection of onabotulinumtoxinA neurotoxin in the glabellar complex affect efficacy of the BoTN for the improvement of glabellar frown lines? STUDY AIM * Primary objective: Compare the efficacy of onabotulinumtoxinA neurotoxin injected at the depth of 2mm vs 4mm for the improvement of glabellar lines * Secondary objective: Determine any adverse effects of onabotulinumtoxinA neurotoxin injected at the depth of 2mm vs 4mm RATIONALE FOR THE PROJECT: Although the use of BoTN for treatment of glabellar lines has long been established as safe and effective, the optimal depth of injection has not been established. Our project hopes to establish the optimal depth of injection for onabotulinumtoxinA neurotoxin for maximal improvement of glabellar lines with minimal adverse effects

Interventions
onabotulinumtoxinA at a depth of 2mm
One time administration of onabotulinumtoxinA to the corrugator supercilii muscles bilaterally. Dosing dependent on the baseline mass and volume of subject's glabellar muscles as assessed by trained cosmetic dermatologist, accounting for symmetry/asymmetry of the face and can range from 10-50 units. Will be administered at a depth of 2mm
onabotulinumtoxinA at a depth of 4mm
One time administration of onabotulinumtoxinA to the corrugator supercilii muscles bilaterally. Dosing dependent on the baseline mass and volume of subject's glabellar muscles as assessed by trained cosmetic dermatologist, accounting for symmetry/asymmetry of the face and can range from 10-50 units. Will be administered at a depth of 4mm
