Botulinum toxin for periocular lines: the single-injection technique.

Area of Science:

• Dermatology
• Aesthetic Medicine
• Ophthalmology

Background:

• Botulinum toxin is a standard treatment for facial wrinkles and hyperfunctional lines, particularly around the eyes.
• Current periocular injection methods often involve multiple punctures.

Purpose of the Study:

• To demonstrate a simplified single-injection technique for periocular botulinum toxin administration.
• To compare the efficacy, safety, and patient preference of a single-injection technique versus the standard multipuncture technique.

Main Methods:

• A comparative study involving 30 patients, with each patient serving as their own control.
• One side of the face received the single-injection technique, while the contralateral side received the standard multipuncture technique, using 10-12 Botox units per side.
• Assessment of outcomes occurred on days 7, 15, and 120 post-injection.

Main Results:

• Both techniques yielded good cosmetic results with no significant difference observed between them.
• The duration of the pharmacological effect was approximately 5 months for both methods.
• Both techniques were equally safe, causing similar levels of bruising, but patients preferred the single-injection method.

Conclusions:

• The single-injection technique is a viable and patient-preferred alternative for treating periocular lines.
• This method effectively reduces patient discomfort compared to the standard multipuncture approach.
• While effective, the single-injection technique necessitates greater operator skill and experience.
