The reason why Dynamic Wrinkles require more in-depth anatomical explanations
Dynamic wrinkles are not just surface wrinkles but they represent the observable product of recurring muscular contractions over the years. In contrast to the type of wrinkles that exist in rest and thus are usually associated with volume loss or the quality of the skin, dynamic wrinkles occur with facial expression. To treat them, one must know not only where the wrinkles develop, but also what muscles develop them, how they inter-relate, and in what way they move under the skin. Cadaver dissection is a rare chance to injectors to study such muscles at a detailed level in which it cannot be appreciated solely by reading books or observing a live patient in real life situations.
Muscular Basis of the Facial Expression
Facial expression is affected by the intricate combination of superficial muscles which penetrate the skin but not the bone. Corrugator supercilii, procerus,orbicularis oculi, frontalis and orbicularis oris are muscles that work in conjunction to form frowning, squinting, smiling, and speaking. As these muscles keep contracting repeatedly with time, they cause dynamic rhytids in anticipated regions such as the glabella, forehead, crows feet, perioral region, and neck. The dissection of cadavers enables injectors to see the precise size, depth and direction of these muscles and rectify the general assumptions formed through observation of the superficial features alone.
What Dissecting cadavers will teach you about muscle movement
The best lesson during cadaver training is observing the overlapping, interdigitating, and different muscles of the faces in different people. It is very rare that muscles work in isolation. E.g. the corrugator supercilii usually acts together with the depressor supercilii and orbicularis oculi, producing intricate patterns of movement that have an effect on glabellar wrinkles. Cadaver dissection demonstrates the course of muscle fibers, the differences in their thickness in different areas, and the alteration of muscle depth with age and anatomy. The knowledge is useful in getting injectors to value the fact that the same injection pattern can have very different outcomes in patients.
Consequences of Neurotoxin Injection Technique
The treatment of neurotoxin requires a high level of accuracy in placement without affecting the muscle functionality and without causing undesired diffusion. Training Cadavers helps understand where the muscle belly actually does exist, how close it is to vital organs and how it is affected by the injection depth. An example of this is the knowledge of the depth and lateral scope of the orbicularis oculi which can be used to avoid over-weakening resulting in false smiles or problems with the eyelids. Likewise, understanding that one should value how the frontalis and brow depressors relate would make injectors to attain a balance in the movements of the brow instead of frozen or heavy appearance.
Lessening Fetal Problems with anatomical precision
Brow ptosis, eyelid droop, asymmetry, or facial expression impairment are some of the neurotoxin-related complications caused by imprecise muscle targeting. Cadaver dissection emphasizes the need of individual assessment as opposed to using templated maps of injections. This is through understanding of the origin, insertion and interaction of muscles which enable injectors to control dosing and placement to relax wrinkles whilst maintaining natural movement. Such precision in the maturity of the anatomical component enhances the aesthetic achievement as well as minimizing the chances of injuries to functionality.
Conclusion
Dynamic wrinkles can directly translate to muscle movements, and to treat them well, one must have a thorough knowledge of face muscles. Cadaver dissection helps to transform the theoretical anatomy into the practical knowledge, and an injector can see the structure, depth and interaction of muscles in the real tissue. This level of anatomical understanding, applied to the neurotoxin treatment, will enable the practitioners to achieve safer and more natural outcomes that do not interfere with the facial expression as well as patient uniqueness.
