Many people worry about horizontal scars left on the lower neck after thyroid surgery. This is because the incision site is not covered by clothing, making it easily visible to others. The most common question we receive is, "Will this scar completely disappear?" To be frank, it is difficult to erase a scar without a trace, but with timely prevention and management, it can be restored to be as close to normal skin as possible.
Why are neck scars particularly noticeable?
Thyroid surgery involves a horizontal incision on the lower neck, leaving a linear scar. The neck is a highly mobile area compared to the face, so it is common for scars to redden or swell during the healing process.
In younger individuals with fewer wrinkles, the lack of lines to conceal the scar can make it even more prominent. While some surgeries align the incision with neck wrinkles, it may not be feasible in all cases, so scars can remain regardless of wrinkles.
The neck is a highly mobile area, increasing the likelihood of hypertrophic scars or keloids. In individuals with a keloid predisposition, swelling is often observed.
When is the best time to start scar treatment?
It is advantageous to start managing surgical scars as early as possible. Generally, it is recommended to begin preventive treatment 1-2 weeks after the stitches are removed.
Even if a surgical scar has already formed, there's no need to give up on management. However, it's good to know in advance that it may require more time and effort compared to starting early.
Three ways to prevent thyroid scars
In consultations, many people think of only one preventive method, but in reality, the combination varies depending on the stage and condition. It can be broadly categorized into three types:
- Ointments and patches: Silicone patches or onion extract ointments can be helpful. However, ointments alone may not provide sufficient effects.
- Laser treatment: Known to have over 50% preventive effect for thyroid surgery scars, and can be received with minimal disruption to daily life.
- Injection treatment: If the wound does not heal quickly or the scar swells, it may be combined with laser treatment.
The appropriate combination among these will vary depending on the scar condition and individual constitution, so it is necessary to assess the condition before starting. If you are curious about the right approach for you, please use chat consultation for thyroid scar treatment.
Be more cautious if the scar is swelling
Even if a thyroid scar is not a keloid scar, it can potentially become a hypertrophic scar. If the surgical site gradually swells, it is better to have it checked by a doctor quickly rather than leaving it as is.
In such cases, Triamcinolone Scar Injection may be considered in conjunction with treatment for the swollen scar to mitigate its progression. The approach varies depending on the extent of progression and individual constitution, so consultation is recommended over self-diagnosis.
Reoperation vs. Laser: Which is better?
Methods to improve existing thyroid scars include reoperation, which involves re-incising the same area, and laser treatment. A simple comparison of the two methods is as follows:
| Method | Features | Considerations |
|---|---|---|
| Reoperation | Re-incises the scar area | Improvement may be limited due to significant constitutional influence |
| Laser treatment | Alleviates scars without incision | Less disruption to daily life and relatively suitable for constitutional scars |
| Adhesion release | Surgery to release adhesions | Limited to rare cases with severe adhesions |
Thyroid scars are heavily influenced by individual constitution, so even with reoperation, the improvement effect may be limited. Therefore, laser treatment is often more suitable than reoperation. However, in some cases with severe adhesions, an approach to release adhesions, such as Surgical Scar Revision, may be necessary.
It's not too late for old scars
Thyroid scars that are old can also be treated. While it may require more time and effort than starting early, with appropriate management, they can be restored to a significantly improved state compared to now.
It's good to keep the following in mind before treatment:
- It may be difficult for scars to completely disappear without a trace.
- The goal is to get as close as possible to normal skin.
- Setting realistic expectations for the desired effect is more reassuring.
- Consistent management, not just a single treatment, helps with recovery.
Even old scars can change significantly with the right approach, so rather than worrying alone, we recommend having your condition checked. Feel free to ask any questions via chat consultation for scar condition assessment.
For cosmetic surgery scars or surgical scars on the neck, the outcome varies greatly depending on the timing and method chosen. Even if the scar doesn't completely disappear, remember that simply starting treatment offers ample potential for improvement.
