Anatomy-based Filler Injection: Diagnosis to Treatment Techniques for the Glabellar Region

Abstract

Glabellar filler injections are a popular non-surgical approach to address depressions and wrinkles caused by aging, muscle activity, and soft tissue loss. An anatomy-based technique emphasizes understanding the complex structure of the glabellar region, including the corrugator supercilii and procerus muscles, and the superficial vascular pathways, such as the supratrochlear and supraorbital arteries. Effective treatment involves precise filler placement, often combined with botulinum toxin to address both volume loss and dynamic wrinkles. Injection techniques like the fern leaf and duck walk methods are preferred to minimize the risk of vascular complications and achieve a smooth, natural appearance. The choice of injection depth and technique is crucial to avoid damaging vital structures and to enhance aesthetic outcomes. Understanding individual anatomic variations and selecting appropriate treatment combinations can significantly improve the safety and effectiveness of glabellar filler injections, providing a rejuvenated and balanced facial appearance.
