ABSTRACT
Background: Facial movements and expression result in brow malposition, therefore, different techniques have been designed to elevate the brow in order to achieve a more aesthetic aspect of the upper third of the face. Botulinum toxin A works by inhibiting the release of acetylcholine from the neuromomuscular junction producing a functional and reversible denervation of the treated muscle, resulting in the most useful cosmetic implementation of the toxin.
Objective: To determine if the application of botulinum toxin on the upper third of the face results in an aesthetic and proper elevation of the brow.
Patients and method: This is a longitudinal, prospective, observational study. 20 patients were treated with botulinum toxin (Botox) in the upper third of the face. A total of 20 units of Botulinum toxin were applied to the orbicularis oculi muscle, 20 to 30 units to the glabella and the middle upper third of the brow and 10 to 15 units to the frontal area. Photographs pre and postapplication were taken and measurements of the brow through the external canthus, midpupillary line and medial canthus to determine brow elevation.
Results: The difference between measurements before and after treatment was statiscally significant in all cases (p ≤ 0.05).
Conclusion: The application of botulinum toxin to the upper third of the face elevates the brows in a significant and safe manner, which constitutes a useful non-invasive technique for elevation of the brow.
