Ultrasound in Aesthetics: Filler and Non-Filler Applications.

Ultrasound in aesthetics presents multiple applications in several areas, including diagnosing fillers and non-fillers complications, the performance of ultrasound-guided injections in real-time, and identifying the most common types of cosmetic fillers. Furthermore, this application of ultrasound in aesthetics has become a must for managing aesthetic patients because, to date, this modality is the one that provides the higher resolution among imaging techniques, detailed anatomical information, and blood flow detection, besides showing worldwide availability. This paper aims to review the current applications of ultrasound in aesthetics based on publications from scientific literature and the authors' experience.

Rationale and Guidelines for the Use of Hyaluronidase: A Practical Guide for Complications Caused by Hyaluronic Acid.

The use of enzyme hyaluronidase to treat the complications of different brands of hyaluronic acid (HA) dermal fillers is increasing in the same proportion as the number of nonsurgical cosmetic procedures. Guidelines for diagnosing and treating complications remain controversial and are primarily based on anecdotal reports and small case series. We proposed approaching HA-related complications based on our clinical research and observations of treating more than 200 patients and providing a practical guide for the thoughtful use of hyaluronidase according to adverse events.

Recalcitrant Sterile Abscesses by Volux: A New Therapeutic Approach.

The number of patients developing sterile abscesses because of hyaluronic acid (HA) filler procedures has increased for unknown reasons. We described this adverse reaction after filling with Juvederm Volux, the latest innovative product in the Vycross range of technology. We presented five patients with recalcitrant sterile abscesses after filling with Juvederm Volux who did not respond to the traditional therapy but whose lesions were resolved with the "Munhoz-Cavallieri lavage protocol" developed and recently published by the present authors.

NOT SO "HAPPY BUMP": A complication due to hyaluronic acid.

Introduction: The use of hyaluronic acid (HA) as a dermal filler is considered safe. However, as new brands come to the market, reports of adverse events are becoming more and more common.

Objective: To describe a particular type of adverse effect that, unlike the erythematous, indurated, and painful nodules described in the literature as "angry red bumps," is characterized by noninflammatory, stony-like nodules that appear in sites previously treated with HA.

Sterile abscess due to hyaluronic acid: A new diagnosis and a proposal for treatment-A series of eight cases.

Background: In recent years, fillers procedures with hyaluronic acid (HA) have grown significantly. Despite HA relative safety, the number of cases of complications after injections has grown, and in many of which, we are not aware of or have little control over.

Aims: In this article, the authors describe a new adverse reaction after filling with HA injection, the sterile abscess.
