Nasal filling guided by high frequency ultrasound: Reducing risks.

[BACKGROUND] Given the significant increase in the quantity of cosmetic procedures utilizing hyaluronic acid fillers, including in the nasal region, the initial evaluation of patients using high frequency ultrasound becomes a crucial instrument in evaluating and handling nonsurgical rhinoplasty.

[AIMS] The aim of this article is to introduce an assessment methodology for nasal filling guided by high frequency ultrasound.

[PATIENTS/METHODS] A prospective and single-center study was conducted with 12 Latin American patients. The patients underwent nasal filling with hyaluronic acid following high power ultrasound mapping.

[RESULTS AND CONCLUSIONS] In the evaluation of the GAIS scale, all patients reported improvement with the treatment. No infections, nodules, ischemia, or other relevant adverse effects were noted. Real-time ultrasound-guided filler techniques have been developed to reduce the risk of vascular compromise, confirming the distribution pattern of blood vessels. It's also crucial to visualize the cannula at the same moment as the vessels, even if the previous vascular mapping was performed. Therefore, the utilization of high frequency ultrasound can act as a pivotal tool in augmenting procedure safety.
