[Orbicularis oculi muscle and crow's feet. Pathogenesis and surgical approach].
Annales de Chirurgie Plastique et Esthétique 1992 October
Crow's feet is one of the characteristic signs of the aging face. Minor techniques designed to obliterate these lesions rapidly demonstrate their limits. The orbital fibers of the orbicularis oculi muscle play a fundamental role in the pathogenesis of wrinkles. Their contracture will create wrinkles in a similar way to the spokes of a wheel perpendicularly to the orientation of the muscle fibers. The dynamic action of the zygomatic muscles contributes to exaggerate these wrinkles. Statically, ptosis of the lateral brow and the aging skin also contributes to these lesions. Surgical treatment can be accomplished by a temporal lift or via a blepharoplasty approach. The vertical fibers of the orbicularis oculi muscle must be corrected by muscle incision or resection, muscle incision and suspension, muscle redraping and fixation, covering of the orbicularis oculi muscle with the malar SMAS. In patients with ptosis of the tail of the eyebrow one must either do a forehead lift or a mask-lift that will redrape the skin. The surface of the skin may require peeling by dermabrasion. Of course, these surgical techniques require a detailed knowledge of the anatomy of this region and especially the distribution of the branches of the facial nerve. The author analyses and compares the results of the different techniques.
