Botulinum toxin (BTX) has revolutionized both aesthetic and therapeutic medicine by selectively inhibiting acetylcholine release at the neuromuscular junction, inducing localized muscle relaxation. However, its use can be associated with various complications. As a diagnostic modality, high-resolution ultrasound can better characterize these complications. Here, we present four clinical cases of complications associated with the application of BTX, along with their corresponding ultrasonographic findings. In this study, cases were selected randomly, irrespective of the timing of BTX injections, to illustrate a spectrum of complications observed in clinical practice. Despite its benefits, BTX can have adverse effects ranging from mild to severe, including aesthetic and functional complications, such as hematoma, ptosis, facial asymmetry, nodules, or pseudoaneurysm. High-resolution ultrasound emerges as a crucial tool in the multidisciplinary management of these complications, allowing for accurate evaluation and effective therapeutic guidance.

Ultrasound Evaluation of Cosmetic Changes in Nails: A Case Series and Literature Review

HFUS effectively identified structural and vascular complications linked to cosmetic nail procedures, often detecting subclinical changes. Methacrylate incorporation into the nail plate may underlie many findings in semi-permanent polish users, while matrix atrophy and ventral pterygium were more typical of acrylic nails. These results highlight the importance of patient education and dermatologic monitoring. Larger studies are warranted to confirm these associations.
