Nasal filling guided by high frequency ultrasound: Reducing risks

Area of Science:

• Aesthetic Medicine
• Medical Imaging
• Plastic Surgery

Background:

• Cosmetic procedures using hyaluronic acid fillers are increasing, particularly for nasal augmentation.
• Nonsurgical rhinoplasty requires careful evaluation and management.
• High-frequency ultrasound (HFUS) is emerging as a key tool for assessing nasal anatomy.

Purpose of the Study:

• To introduce a novel assessment methodology for nasal filling procedures.
• To demonstrate the utility of high-frequency ultrasound in guiding hyaluronic acid injections.
• To enhance the safety and efficacy of nonsurgical rhinoplasty.

Main Methods:

• A prospective, single-center study involving 12 Latin American patients.
• High-frequency ultrasound was used for pre-procedure vascular mapping of the nasal region.
• Hyaluronic acid fillers were administered under ultrasound guidance.

Main Results:

• All patients reported significant aesthetic improvement based on the GAIS scale.
• No adverse events such as infections, nodules, or ischemia were observed.
• Ultrasound guidance confirmed vessel distribution and allowed real-time visualization of the cannula relative to vessels.

Conclusions:

• High-frequency ultrasound is a pivotal tool for augmenting safety in hyaluronic acid nasal fillers.
• Real-time ultrasound guidance reduces the risk of vascular compromise during nonsurgical rhinoplasty.
• Integrating vascular mapping and real-time visualization enhances procedural safety.
