Pain-free and safe cyst treatment

A safe surgery experience with pain-free cyst treatment

When it comes to sebaceous cyst treatment, the thing patients worry about most is the pain of surgery, right? In particular, many people are afraid of the scalpel being used. At our clinic, we use a sufficient amount of local anesthesia to provide painless sebaceous cyst treatment. By minimizing pain, we reduce the burden on patients and provide more comfortable treatment.

Thoroughly analyze the cause of pain and implement appropriate measures

There are three main reasons why pain occurs during cyst surgery:

Local anesthetic injection pain: You will feel pain when the needle is inserted and when the anesthetic is injected.
Pain during skin incisionIf the anesthesia has not worked properly, you may feel a tingling pain.
Dull pain after surgery: You may feel a slight dull pain after the surgery, but this will usually subside within 1 to 2 days.

In our clinic, we use the following techniques to minimize these pains:

Local anesthesia using ultra-fine needles: To minimize the pain of the injection, we use ultra-fine needles, especially in the face. Ultra-fine needles cannot be used in areas with thicker skin, such as the back and buttocks, because they will bend, but we try to use needles as thin as possible.
Ensuring sufficient anesthesia time: We will allow time for the anesthesia to take effect properly, and then perform the surgery without you feeling any pain.
Smooth treatment by experienced doctors: The shorter the surgery time, the less pain you will feel. Our specialists perform the procedure efficiently and complete the procedure in as little as 10 minutes. However, the time required varies depending on the size and location of the cyst.

Testimonials from patients who have undergone surgery

Many patients who have undergone cyst surgery at our hospital are surprised that it was over in a flash and they didn't feel any pain.

Surgery with sutures
- If stitches are used to close the wound, they will need to be removed after about a week.

Frequency of visits to the hospital varies by body part
- Visible areas such as the face and neck → Progressive monitoring is important to make scars less noticeable.
- Areas such as the back and legs → The wound condition is more likely to stabilize, minimizing the need for follow-up visits.

When the risk of infection is low
- With proper care, you won't need to visit the hospital.
- Provide thorough instructions on how to care for wounds at home.
If you are at high risk of infection or inflammation
- Postoperative follow-up is required and several visits to the hospital are recommended.
- If redness, swelling, or pain persists, you should see a doctor.
