Case Scenario

Patient Background: A woman in her 30s who received hyaluronic acid injection rhinoplasty at a cosmetic clinic approximately 18 months prior. The initial result was satisfactory, with a straighter nasal bridge. However, approximately 4 months post-injection, the patient noticed asymmetry along the nasal dorsum — one side appeared wider than the other, and the filler could be felt in positions different from the original injection sites.

Treatment History:

• First noticed left-sided nasal dorsum prominence approximately 4 months post-injection

• Returned to the original clinic and was advised that "mild asymmetry will resolve naturally"

• Waited an additional 3 months, but asymmetry worsened rather than improved

• Underwent hyaluronidase injection at the original clinic, but results were uneven — some areas over-dissolved while others remained inadequately treated

• Post-dissolution nasal contour became more irregular with surface bumps and depressions

• Found information about ultrasound-guided precision extraction through online research

Presentation at Consultation:

• Visible nasal dorsum asymmetry with left-sided prominence

• Palpation revealed irregular distribution of residual filler in multiple locations

• Several areas of surface irregularity on the nasal dorsum (evidence of uneven hyaluronidase treatment)

• Slight tip rounding with loss of original refinement

• Patient's dissatisfaction with nasal appearance had significantly impacted social confidence

Deep Analysis

Root Cause Analysis

> Key Insight: The nose is a high-risk zone for filler displacement. Nasal skin is thin, tissue space is limited, and the area is subject to continuous movement from facial expressions. Once displacement occurs, non-guided hyaluronidase injection often fails to address the problem precisely — it may over-dissolve in areas that don't need treatment while inadequately reaching the actual displaced material. Ultrasound guidance is the critical tool for managing these complex nasal filler complications.

Doctor's Perspective

"Nasal filler displacement is a remarkably common complication we encounter in our clinic. This patient's situation represents a classic treatment dilemma: after filler displacement occurs, non-guided hyaluronidase injection actually makes the problem more complex. Ultrasound examination clearly showed the distribution of residual HA — it was no longer concentrated along the nasal midline but had spread laterally to the left, with some material having migrated to unexpected positions.

The key principles for managing these cases are: first, use ultrasound for a complete assessment of the precise location and extent of residual filler; second, develop a zone-by-zone treatment strategy — perform targeted extraction of clearly identified deposits rather than blind dissolution; third, protect the nose's normal tissue architecture during extraction, particularly the delicate anatomical layers above the dorsal cartilage perichondrium."

Treatment Plan and Process

Preoperative Planning

Surgical Process

Precise local anesthesia: Ultrasound-guided nasal nerve block and local infiltration

Zone-by-zone scan confirmation: Pre-operative re-confirmation of filler locations in each zone

Priority treatment of most displaced area: Beginning with the left dorsal displacement accumulation zone

Real-time ultrasound guidance: Operating entirely under ultrasound visualization to ensure instrument accuracy

Stepwise precision extraction: Using micro-instruments to extract residual filler incrementally, avoiding excessive tissue disruption

Immediate assessment: Scanning after each extraction to confirm results

Symmetry verification: Post-extraction comparison of bilateral nasal dorsum symmetry

Extraction Results

Multiple irregularly distributed residual HA deposits were successfully extracted, including partially degraded old filler masses. Extracted material ranged from translucent gel-like consistency to opaque, denatured masses — reflecting the different states resulting from varying injection periods and prior hyaluronidase treatment. Post-operative ultrasound confirmed significant reduction in residual material across the nasal dorsum.

Key Patient Notes

Special Considerations for Nasal Extraction

Recovery Expectations

> Key Insight: Recovery after nasal filler extraction requires particular patience. The nose is the visual focal point of the face — even slight swelling is easily noticeable. It is important to understand that the immediate post-operative appearance is not the final result. As swelling resolves and tissue remodels, the nasal shape will progressively return to a more natural state.

Clinical Takeaways

Nasal filler displacement warrants early evaluation — waiting for "natural absorption" typically only delays treatment; displaced filler does not return to its original position on its own

Non-guided hyaluronidase injection carries high risk in the nose — the nose's delicate structure makes blind dissolution likely to produce uneven results

Ultrasound is foundational for nasal filler problem management — precise localization enables precise treatment

Post-extraction nasal assessment needs time — additional procedures should not be rushed during the swelling phase

Choose a physician with nasal anatomy expertise — the nose's fine structure demands deep anatomical knowledge

If you are experiencing nasal filler complications, schedule a consultation for a precision ultrasound assessment.
