Techniques for the Safety Use of High-Frequency Ultrasound-Guided for Facial Procedures: A Technical Note

Background: The knowledge of facial anatomy and its correlation with ultrasonography is crucial for several professionals in clinical practice. Therefore, understanding facial anatomical structures through dynamic ultrasonography images is essential for the clinical practice of guided aesthetic facial procedures. The purpose of this study is to demystify and provide a clear understanding of high-frequency guided ultrasound in facial aesthetic procedures, using visual aids and analogies to simplify the learning process. Study Design: The authors present a technical note outlining a protocol for the safe use of high-frequency ultrasound-guided facial procedures. Discussion: Proper training is necessary for the use of high-frequency ultrasound in facial procedures to enhance the quality of treatments and achieve more positive outcomes. This technology allows real-time monitoring of the muscular and vascular anatomy while applying injectable products on the face, helping to prevent complications such as vascular occlusions. However, guided aesthetic procedures often face challenges due to operators' lack of experience and knowledge of correct protocols. To address this, we provide a step-by-step approach to performing ultrasound-guided procedures more efficiently. The pedagogical approach used in this manuscript, utilising a flight plan analogy, provides a clear and concise understanding of the practical application of ultrasound (US) in facial aesthetics, making the learning process simple and effective.
