"Ultrasound does not transform injection, it makes it safer."
Injections of toxin or fillers can cause side effects, most often mild and temporary (asymmetries, irregularities, swelling, bruising).
However, fillers expose patients to more severe complications, including infections, inflammatory nodules, and above all vascular complications such as necrosis or blindness.
Their global incidence is alarmingly increasing: 150,000 cases of necrosis and around 95 cases of blindness per year. The latter, particularly feared, leads to irreversible vision loss in 70% of cases despite appropriate medical management.
Ultrasound is the only tool that is easy to use in daily practice, fast and effective for securing injections by visualizing in real time the needle or cannula and their interactions with surrounding anatomical structures. It allows adjustments in their position and orientation to avoid vascular trauma, thus reducing the risk of severe complications while optimizing the precision of the result.
Ultrasound is a key tool in managing complications from injections, offering real-time visualization from the epidermis down to the bone. For botulinum toxin, it makes it possible to visualize muscles and adjust treatment precisely to avoid asymmetry or insufficient effect, ensuring a harmonious result.
For nodular reactions to fillers, it helps distinguish between an inflammatory reaction and product accumulation, identify the type of product injected, and assess its integration into tissues. In cases of persistent inflammation, it guides the precise injection of hyaluronidase (an enzyme that breaks down hyaluronic acid) or corticosteroids (anti-inflammatories), optimizing their effectiveness.
In the event of a vascular complication, it locates the obstruction, guides the injection of hyaluronidase, and immediately confirms the restoration of blood flow, ensuring rapid and effective intervention in the actual area of obstruction.
Although useful in aesthetic medicine, traditional ultrasound devices are not optimal. Their large size and limited maneuverability make them poorly suited for the precision required.
Their use occupies one hand, reducing the practitioner’s dexterity and making the procedure far from a standard injection, often requiring assistance from a third person. This hinders fluidity and complicates their integration into daily practice. In addition, rigid linear probes require a large amount of gel and adapt poorly to the curved contours of the face, affecting both image quality and the comfort of the patient and practitioner.
SIBUS is the first high-frequency digital ultrasound probe. Unlike traditional devices, its miniature, very lightweight format and its positioning on a finger of the non-injecting hand allow intuitive, natural, and hands-free use without assistance.
Its curved probe is designed to adapt to facial contours, optimizing imaging of concave structures. Thanks to high-resolution B-mode and Doppler, it enables precise identification of anatomical planes and vessels, thus maximizing safety and precision.
The aim of SIBUS is to support the gesture without constraining it, extending the practitioner’s touch and tissue palpation with a real-time anatomical view beneath the skin.
Attached to a finger of the non-injecting hand, SIBUS preserves the mobility of both hands, enabling the practitioner to inject under ultrasound guidance while maintaining natural gestures.
The dominant hand remains dedicated to administering the treatment, while the other guides the injection under ultrasound without compromising tissue palpation. On the injecting hand side, a needle and/or echogenic cannula—used here for the first time—makes it much easier to visualize their movement beneath the skin.
Its compact shape reduces the amount of gel required, improving comfort for both patient and practitioner. Its ergonomic design reduces fatigue and facilitates use in consultations. This design makes it possible to integrate ultrasound while adapting optimally to practitioners’ existing injection habits.
Ultrasound allows practitioners to adapt injection techniques according to patient anatomy, contributing to more precise care. It also provides certainty regarding proper product placement in the desired plane, while limiting the risk of vascular complications.
In case of an adverse effect, it serves as a first-class diagnostic and therapeutic tool, enabling targeted, measured, and immediately verifiable intervention.
For patients, ultrasound guidance is often perceived as an added safety factor, strengthening trust in the practitioner and highlighting the technical sophistication of the procedure.
For experienced injectors, SIBUS is a strategic tool to be used in a targeted way, particularly in complex areas or with high-risk patients. Without disrupting their practice, it provides an added layer of safety, documents the procedure with photographic or video records of the injection under ultrasound guidance, and may serve as a medico-legal safeguard in case of complications. Its gradual integration also aligns with evolving practices, where ultrasound guidance is becoming a differentiating standard.
For novice injectors, it represents a learning and reassurance tool, allowing them to adjust their technique and secure their gestures for both toxin and filler injections. By strengthening the confidence of both practitioner and patient, it accelerates skill development and enhances credibility in a competitive environment.
