The SibUS-In Finger Probe: An Alternative Device and Method for Ultrasound-Guided Injections

Conventional ultrasound systems in aesthetic medicine are often bulky, single-hand operated, and poorly adapted to facial anatomy, limiting their practicality during injectable procedures. These ergonomic and workflow constraints have restricted the integration of ultrasound guidance into routine practice. The SibUS-In (safe injection by ultrasound) probe was specifically designed for aesthetic injections, integrating a high-frequency transducer onto the injector's fingertip to enable simultaneous palpation, scanning, and injection. This configuration restores 2-hand coordination and allows real-time visualization of facial structures while maintaining dexterity. In clinical use, the device combines ergonomic comfort, intuitive handling, and high-quality imaging that supports continuous vascular mapping and procedural control. The present article illustrates the practical application of the SibUS-In probe across different facial regions and procedural stages, highlighting its potential to facilitate ultrasound-guided injections. Further studies are warranted to evaluate quantitative outcomes and define standardized protocols for its broader clinical adoption. Level of Evidence: 5 (Therapeutic).
