Why Ultrasound Guidance Matters for Filler Removal
Most filler dissolution in Los Angeles is still performed blindly by feel, relying on the injector's estimate of where the filler has gone. Ultrasound changes this completely.
Precise Targeting
Ultrasound shows the exact location, depth, and size of filler deposits in real time. Dr. Karamanoukian can see each pocket of migrated or accumulated filler and direct the dissolving enzyme precisely into it, using less hyaluronidase and achieving a more complete result than blind injection allows.
Vascular Safety
High-frequency ultrasound maps blood vessels in the treatment area before any needle is placed. This is especially critical near the eyes, nose, and lips where accidental vascular injection of hyaluronidase can cause serious complications. Ultrasound guidance dramatically reduces this risk by showing vessel location in real time.
Identification of Filler Type
Different fillers produce characteristic patterns on ultrasound. HA fillers appear as anechoic or hypoechoic deposits. PMMA shows bright echogenic deposits with comet-tail artifacts. Silicone produces a distinctive snowstorm reverberation pattern. This lets Dr. Karamanoukian identify what material is present before selecting the removal approach.
Types of Filler Treated for Migration and Removal
Hyaluronic Acid Fillers
Includes Juvederm, Restylane, Versa, Belotero, Voluma, Volux, and all other HA-based fillers. These are dissolved with hyaluronidase under ultrasound guidance. Highly cross-linked HA fillers such as Voluma require more enzyme and may need multiple sessions. Results typically appear within 24 to 48 hours.
PMMA (Bellafill)
PMMA is a permanent synthetic filler that cannot be dissolved with hyaluronidase. Migrated or problematic PMMA requires surgical excision. Dr. Karamanoukian performs open surgical removal of PMMA deposits from the face, lips, and other areas. Ultrasound is used preoperatively to map the location and extent of PMMA before surgery.
Silicone and Biopolymers
Liquid silicone, PAAG (aquagel), and other biopolymers cannot be dissolved. They require surgical removal. Dr. Karamanoukian is a nationally recognized specialist in silicone and biopolymer removal from the face, lips, and body. Learn more on our silicone removal page and our biopolymer side effects page.

Three Filler Removal Options at Kare Plastic Surgery
Closed Technique: Ultrasound Guided Hyaluronidase
For hyaluronic acid fillers, hyaluronidase is injected directly into filler deposits under real-time ultrasound guidance. The enzyme breaks down the bonds in the HA filler molecules, which are then metabolized by the body over 24 to 48 hours. Ultrasound guidance ensures each deposit is targeted accurately, minimizes the enzyme used, protects nearby blood vessels, and produces a more even dissolution than blind injection. Most patients need one to three sessions. Hylenex is the preferred hyaluronidase formulation used at Kare Plastic Surgery due to its superior dissolution performance.
Open Technique: Surgical Filler Removal
Fillers that cannot be dissolved, including PMMA, silicone, calcium hydroxylapatite (Radiesse), and poly-L-lactic acid (Sculptra), require surgical excision when removal is needed. Dr. Karamanoukian performs open surgical removal through carefully planned incisions that minimize visible scarring. Ultrasound is used preoperatively to map filler location and depth so the surgical plan addresses all affected areas. This approach is also used for very large or calcified HA filler collections that do not fully respond to hyaluronidase dissolution.
Silicone and Biopolymer Removal
Liquid silicone injections into the face, lips, nose, and body produce a particularly challenging form of filler complication because the material disperses through tissue planes and cannot be dissolved or extracted by simple aspiration. Dr. Karamanoukian is one of the country's foremost experts in silicone removal from the face and body, using open surgical excision with ultrasound-guided preoperative mapping. The Karamanoukian Grading Scale for Soft Tissue Inflammation is used to classify disease severity and guide the surgical plan. See our silicone disease complications page for more detail.
Tyndall Effect and Under-Eye Filler
The Tyndall effect is a bluish discoloration visible through the skin of the under-eye area caused by superficially placed HA filler that scatters light. It is one of the most common filler complications in the tear trough and is treated with ultrasound guided hyaluronidase directed precisely into the superficial filler pocket. Blind dissolution in this sensitive area carries higher risk of uneven results and complications. Ultrasound guidance is considered the standard of care for under-eye filler removal. Call (310) 998-5533.
Filler complications are treated at Kare Plastic Surgery from across the United States: Patients travel to Santa Monica from Los Angeles, Beverly Hills, Miami, New York, and across the country for Dr. Karamanoukian's ultrasound guided filler removal expertise. Bring any records of what filler was used, where, and how many syringes were placed. This helps plan the most complete and targeted removal. Call (310) 998-5533.
"Ultrasound transforms filler removal from guesswork into precision. When I can see exactly where the filler is, how deep it is, and what blood vessels are nearby, I can dissolve precisely what needs to go and protect everything else. That is the standard of care, and it is what every patient deserves."

Frequently Asked Questions
Why is ultrasound guidance important for filler removal?
Ultrasound guidance allows the physician to see exactly where filler is located in real time, including migration, depth, and pockets that cannot be identified by touch. It also maps blood vessels so the enzyme is injected precisely into the filler while avoiding vascular injury. Blind dissolution relies on flooding the area with hyaluronidase, which is less accurate and more likely to produce uneven results. Dr. Raffy Karamanoukian at Kare Plastic Surgery in Los Angeles performs ultrasound guided filler removal. Call (310) 998-5533.
Can PMMA and silicone be removed with hyaluronidase?
No. Hyaluronidase only dissolves hyaluronic acid-based fillers. PMMA, liquid silicone, calcium hydroxylapatite, and poly-L-lactic acid do not respond to hyaluronidase and require surgical removal. Dr. Karamanoukian at Kare Plastic Surgery evaluates each patient's filler type and designs the appropriate removal protocol. Call (310) 998-5533.
How many hyaluronidase sessions are needed to remove filler?
Most patients require one to three sessions, though highly cross-linked fillers like Juvederm Voluma may require five to six vials per syringe and multiple sessions. Ultrasound guidance improves efficiency by targeting the enzyme precisely. Dr. Karamanoukian evaluates each case individually. Call (310) 998-5533.
What areas can be treated for filler migration at Kare Plastic Surgery?
Dr. Karamanoukian treats filler migration in the lips, under the eyes, cheeks, nose, jawline, chin, and other areas of the face and body. Ultrasound guided removal is used for all facial areas, with special precision in high-risk zones near the eyes, nose, and lips. Call (310) 998-5533.
How quickly do results appear after hyaluronidase treatment?
Results begin within 24 hours of hyaluronidase treatment, with the full effect typically visible within 48 to 72 hours. Some swelling from the injection itself is normal for the first day and settles as the enzyme works. Additional sessions are scheduled when needed after the initial result has fully appeared. Call (310) 998-5533.
