ABSTRACT
The formation of glabellar lines is associated with repeated pulling of the skin by the underlying musculature. Movement of the transverse head of the corrugator supercilii muscle produces the vertical glabellar line, while the oblique head of the corrugator supercilii and the depressor supercilii and orbicularis oculi muscles contribute to the formation of the oblique glabellar line1-3. Treatments designed to minimize the appearance of glabellar lines include dermabrasion, chemical peel, and injection of collagen, silicone, autologous fat or dermis, or polytetra-fluoroethylene. Surgical options include endoscopy or limited incision to modify function of the corrugator supercilii and procerus muscles, and direct excision of the glabellar line1,4.
