This single blinded randomized pilot study was performed on 21 Caucasian females to determine if injections through follicular openings were less painful than traditional injections for cosmetic botulinum toxin type A injections.

Condition Intervention
Drug: botulinum type a

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Single Blind (Participant)
Primary Purpose: Supportive Care
Official Title: Novel Technique for Botulinum Toxin Injection to Minimize Patient Discomfort

Further study details as provided by Henry Ford Health System:

Primary Outcome Measures:
  • Decrease pain on injection for treatment intervention assessed on a 10 point scale [ Time Frame: At time of intervention ]

Enrollment: 21
Study Start Date: January 2007
Study Completion Date: May 2007
Primary Completion Date: May 2007 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: botulinum type a
    12 Units total were injected into 6 sites in the glabellar complex to determine if injecting through the follicle versus a traditional approach would decrease patient discomfort
    Other Name: Botox
Detailed Description:

Objective: To investigate whether injection of botulinum toxin type A is less painful if performed through follicular openings versus traditional non-specific approach.

Design: Prospective, randomized, single-blinded study.

Setting: Academic dermatology department.

Patients: A volunteer sample of twenty female patients aged 25-55 who had no prior history of botulinum toxin injection.

Intervention: Each patient received six randomized injections of botulinum toxin type A (Botox® Allergan). Two injections into the procerus muscle and two into each corrugator muscle. Three of the injections were performed through follicular openings and three were performed traditionally.

Main Outcome Measure: Patient discomfort on a 1-10 scale and direct comparison between the two injection techniques.
