Botulinum toxin dosage template for frontal wrinkle effacement.

Area of Science:

• Aesthetic Medicine
• Dermatology
• Cosmetic Procedures

Background:

• Lack of consensus on optimal botulinum toxin injection techniques for natural frontal aesthetics.
• Need for standardized methods to guide precise toxin placement.

Purpose of the Study:

• Introduce a safe and effective "dose disc" template for botulinum toxin injections in the frontal region.
• Achieve natural wrinkle effacement while preserving some facial movement.
• Provide a practical method for estimating toxin spread and guiding injection positioning.

Main Methods:

• Study included 50 adult patients with frontal expression wrinkles.
• Patients were divided into two groups for sequential or simultaneous frontal and glabellar injections.
• All injections utilized the "dose disc" for pretreatment marking and positioning.

Main Results:

• 317 injections were performed using the dose disc with a low failure rate (7/50 patients).
• Failures were primarily due to irregular disc positioning, with successful correction via additional injections.
• No significant side effects like palpebral or eyebrow ptosis were observed.

Conclusions:

• The fixed "dose disc" template is a valuable tool for accurate botulinum toxin injections in the frontal area.
• Further research is needed for optimized disc models, varied doses, and application to other facial regions.
• The goal is to enhance treatment efficacy, duration, and expand template utility.
