Цели: This presentation aims to introduce a modified fan technique designed to maximize the biostimulatory properties of injectable products. By refining the classic approach, physicians can achieve more efficient product utilization, greater tissue stimulation, and ultimately superior clinical results in their patients. Введение: As a practitioner with more than 17 years of experience in aesthetic medicine, I have identified a potential limitation in the widely adopted use of cannula techniques for delivering biostimulators. Although cannulas are traditionally valued for their safety and precision, both clinical observations and theoretical analysis suggest that this method may unintentionally result in uneven product distribution across tissue planes, leading to suboptimal biostimulatory effects Материалы / методы: When using a cannula, equal volumes of biostimulator are deposited along its trajectory. However, due to the geometry of injection, the tissue surface area covered near the cannula entry point is much smaller than in more distal regions—approximately three times smaller with 70mm cannula. As a result, distal tissue receives significantly less product per unit area. This disproportionality is even more pronounced with shorter cannulas. These observations formed the basis for developing a modified fan technique aimed at achieving more balanced distribution of biostimulators. Результаты: To overcome the limitations of the classic approach, we propose a revised injection protocol designed to ensure more uniform tissue coverage (Figure 2). The modification involves doubling product delivery in distal regions by adjusting the injection pattern: instead of continuous deposition along the full cannula length, every second pass is intentionally shortened to half of the trajectory from the distal end. This adjustment allows for more balanced distribution and enhanced biostimulatory effect. I'll show videos of the new modfied fanning technique. Заключение: Conclusions The modified fan technique offers a simple yet effective adjustment to achieve more uniform product distribution and improved biostimulatory outcomes. This approach enhances both precision and clinical results, providing physicians with a practical tool for daily practice.
