Ultrasound in Aesthetic Medicine: Identifying Fillers and Managing Complications

Conclusions

• High-frequency ultrasound is now a practical and important tool in aesthetic dermatology for diagnosing and managing filler-related complications.
• Ultrasound can reliably identify many injected substances by their characteristic appearance, even when patient histories are incomplete or inaccurate.
• Similar clinical presentations such as under-eye swelling can reflect very different causes, including filler deposits, fat grafts, silicone migration, panniculitis, granuloma, or abscess.
• Clinical examination alone is often misleading, so imaging is needed to reach the correct diagnosis and guide treatment.
• Ultrasound findings help distinguish inflammatory swelling from solid vascular granulomas and from fluid collections such as abscesses.
• When a complication is identified, ultrasound enables safer and more precise interventions, including targeted drainage and hyaluronidase injection.
• Ultrasound-guided hyaluronidase appears more effective than blind injection because it reduces punctures, lowers enzyme use, and improves accuracy.
• In suspected filler-associated abscesses, ultrasound-guided drainage plus lavage can resolve symptoms, particularly when cultures are negative and the collection is sterile.
• Overall, ultrasound improves both diagnostic confidence and procedural outcomes in aesthetic complication management.
• The presentation concludes that ultrasound should be considered an essential part of the clinician’s toolkit when evaluating and treating adverse events after aesthetic procedures.
