Article Synopsis
- Myomodulation involves enhancing muscle contraction and relaxation through techniques like hyaluronic acid (HA) injections, focusing on the precise anatomical positioning in high-risk areas like the forehead to ensure safety and efficacy.
- The study involved injecting HA into four specimens using three different methods by five experienced plastic surgeons, with ultrasound analysis to evaluate accuracy.
- Results showed that the microcannula and 45-degree needle techniques were effective in delivering filler accurately to the desired layer, while the 90-degree needle caused dispersion of the filler, indicating the importance of technique choice for optimal outcomes.
Improvements in Botulinum toxin type-A (BoNT-A) aesthetic treatments have been jeopardized by the simplistic statement: "BoNT-A treats wrinkles". BoNT-A monotherapy relating to wrinkles is, at least, questionable. The BoNT-A mechanism of action is presynaptic cholinergic nerve terminals blockage, causing paralysis and subsequent muscle atrophy.
