The Impact of Botulinum Toxin on Brow Height and Morphology: A Randomized Controlled Trial

May 11, 2017 updated by: samer jabbour, St Joseph University, Beirut, Lebanon
The purpose of this study is to describe three safe and reproducible techniques for brow lifting using botulinum toxin. It will also describe the effect of 2 techniques on the eyebrow shape using quantitative, objective measurements and satisfaction scales.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Technique 1: Lateral orbicularis injections
5 equally spaced injections will be placed intramuscularly into the orbicularis under the lateral eyebrow starting lateral to the level of the lateral limbus and extending to the level of the inferior orbital rim.
Other Names:
  • abobotulinumtoxineA
Active Comparator: 2. Technique 2: Lateral orbicularis and Corrugator injections
5 equally spaced injections will be placed intramuscularly into the orbicularis under the lateral eyebrow starting lateral to the level of the lateral limbus and extending to the level of the inferior orbital rim. In addition, 2 injections will be placed into the corrugator at the medial brow
Other Names:
  • abobotulinumtoxineA

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Objective assessment
Time Frame: 15 days post treatment
Objective assessment will be done on anteroposterior views of pre-and-post injection photographs. The mid pupillary line will be drawn and the eyebrow vertical height will be measured from this line to the upper border of the brow at seven horizontal points: the most medial aspect of the eyebrow, medial canthus, medial limbus, mid pupil, lateral limbus, lateral sclera, and most lateral eyebrow.
15 days post treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient satisfaction
Time Frame: 15 days post treatment

Patient satisfaction will be determined by a questionnaire completed at 15 days post-treatment. Subjects will indicate how satisfied they are on a 4-point scale (1-4) as follow:

  1. Very Satisfied
  2. Satisfied
  3. Dissatisfied
  4. Very Dissatisfied.
15 days post treatment
