The nasolabial area is an anatomical region extending from the side of the nose to the corner of the mouth and is directly affected by facial expressions along the midline of the face. Fillers applied to this area can be planned with the aim of;
- Softening the nasolabial fold,
- Providing volume support to the area,
- Balancing the transition line.
However, in some cases, the filler material may:
- Settle superficially,
- Distribute irregularly within the tissue,
- Become prominent along the expression line,
- Create an unnatural appearance.
Ultrasound-guided dissolution of nasolabial fillers is an imaging-supported approach used to evaluate the filler material in this area and to reduce it in a controlled manner when necessary.
Why Is Nasolabial Filler Dissolved?
The most common reasons for evaluating nasolabial filler after application include:
- Superficial filler placement,
- Irregular distribution,
- Asymmetry,
- A feeling of hardness,
- Prominence of the filler along the expression line.
Since the nasolabial area is a constantly moving anatomical region, the filler material may shift outside the natural line over time or concentrate in certain areas.
In some individuals, the filler material may create segmental bulges instead of distributing homogeneously along the nasolabial fold. In some cases, the filler becomes more noticeable during facial expressions, stiffening the natural transition line of the face.
This situation is related not only to volume increase but also to the placement plan of the filler within the tissue.
Ultrasound-guided dissolution of nasolabial fillers helps in planning the procedure more precisely by evaluating which anatomical plane the filler material is located in.
How Does Ultrasound Evaluate Nasolabial Fillers?
Assessing filler placement in the nasolabial area by physical examination alone may not always be sufficient. Especially in individuals who have had repeated filler applications, the distribution of the filler material within the tissue may not be fully distinguishable through clinical examination.
Ultrasonography assists in real-time evaluation of the filler material placement in the nasolabial area. With this examination:
- The superficial or deep placement of the filler,
- The anatomical plane it occupies,
- Its distribution within the tissue,
- Its relationship with surrounding anatomical structures can be more clearly assessed.
Vascular structures in the nasolabial area must be carefully preserved. Therefore, ultrasound-guided evaluation is important not only to locate the filler material but also to create a more controlled procedure plan.
Why Is Ultrasound Important in Nasolabial Fillers?
The nasolabial area is a dynamic anatomical region directly affected by facial expressions.
Ultrasound;
- Helps determine the placement of the filler material,
- Assesses the anatomical plane where the filler is located,
- Examines irregular distribution within the tissue,
- Reveals its relationship with surrounding anatomical structures,
- Assists in making the procedure planning more controlled.
How Is Ultrasound-Guided Nasolabial Filler Dissolution Planned?
The ultrasound-guided nasolabial filler dissolution procedure is most commonly evaluated with hyaluronic acid-based fillers.
Before the procedure:
- The placement of the filler,
- The density of the filler material,
- Its distribution within the tissue,
- Its effect on the natural expression line,
- Its relationship with surrounding anatomical structures are examined.
Not every nasolabial filler needs to be completely dissolved. In some cases, correcting only certain areas or reducing the amount of filler in a controlled manner may be sufficient.
The goal is not only to reduce the existing filler material but also to reassess the anatomical balance of the nasolabial line in a more controlled way.
Post-Procedure Process
The post-procedure process may vary depending on the placement and application area of the filler. Since the nasolabial area is a dynamic region affected by facial movements, short-term sensitivity may be observed after the procedure.
During the follow-up process:
- The appearance of the treated area,
- Sensitivity and tissue response,
- The current state of the nasolabial line,
- The distribution of the filler material,
- The need for re-evaluation can be reviewed.
If necessary, the area is re-evaluated and the follow-up plan is adjusted accordingly.
Ultrasound-guided nasolabial filler dissolution is an imaging-supported approach that not only helps reduce the existing filler material but also aids in more accurate evaluation of the nasolabial anatomy and more controlled planning of subsequent applications.
