What part of the Body does the Procedure involve?

  • The Subcision procedure involves scars seen on many areas of the body; these scars may be from several sources
  • The majority of Subcision surgical procedures are done to improve acne scars on the face

Why is the Subcision surgical procedure Performed?

Subcision is primarily performed for acne scars that are pulled downward below the surrounding skin by collagen scar strands tethered to deeper structures.

What are some Alternative Choices for the Procedure?

An alternative for Subcision includes open surgical cutting of visualized collagen scar bands.

What are the Recent Advances in the Procedure?

Currently, no significant advances specific to Subcision procedure are reported.

What is the Cost of performing the Subcision surgical procedure?

The cost of the Subcision procedure depends on a variety of factors, such as the type of your health insurance, annual deductibles, co-pay requirements, out-of-network and in-network of your healthcare providers and healthcare facilities.

In many cases, an estimate may be provided before the procedure. The final amount depends upon the findings during the surgery/procedure and post-operative care that is necessary.

When do you need a Second Opinion, prior to the Procedure?

  • It is normal for a patient to feel uncomfortable and confused with a sudden inflow of information regarding the Subcision procedure and what needs to be done
  • If the patient needs further reassurance or a second opinion, a physician will almost always assist in recommending another physician
  • Also, if the procedure involves multiple steps or has many alternatives, the patient may take a second opinion to understand and choose the best one. They can also choose to approach another physician independently

Prior to Subcision surgical procedure:

How is the Subcision surgical procedure Performed?

The Subcision procedure is performed in the following manner:

  • The skin around and under the depressed or tethered scar is infiltrated with local anesthetic 
  • A large bore sterile injection needle is pierced under the scar at a 30-45 degree angle into the subcutaneous fat layer. The needle is swept side to side, at changing depth of penetration, such that the sharp tip cuts through bands of scar tissue tethering the scar down
  • Successfully cutting these collagen bands leads to elevation of the scar to the proper plane, so the surgeon simply withdraws the needle
  • If bruising or a hematoma appears, pressure and cold are used to obtain hemostasis

Where is the Procedure Performed?

The Subcision procedure is usually performed in a clinic procedure room, or outpatient surgical procedure suite.

Who Performs the Procedure?

A physician, trained physician assistant, or advanced practice nurse usually performs the Subcision procedure.

How long will the Procedure take?

The Subcision procedure usually takes about 30 minutes.

What do you need to tell your Physician before the Procedure?

  • Provide medical history such as diabetes, hypertension, heart disease, etc. (if any)
  • Provide a complete list of medications you are currently taking to the physician. This information is useful for a variety of reasons. For example, it can help your healthcare provider prevent complications due to a drug interaction
  • If you are allergic to any specific medication or food items
  • If you are taking blood thinners, such as aspirin, warfarin, herbal supplements, or any other such medications
  • Any medical or family history of bleeding disorders or blood clots
  • If you have ever been diagnosed with blood clots in your leg (deep vein thrombosis) or lung (embolism of lung)
  • Any unusual effects of anesthesia from prior surgery
  • A list of all previous surgical procedures you have undergone, like for example - removal of appendix, gallbladder, or any other part, of your body; surgical repair of any body part, such as hernia repair, perforation of bowel wall, etc.

What Preparations are needed, prior to the Procedure?

The physician performing the procedure will evaluate the patient prior to the procedure and discuss the details with risks for complications and obtain his/her permission (termed informed consent).

  • Some medications increase a person’s chances of bleeding and it may be recommended to discontinue them for a period of time, before the procedure is performed
  • Blood tests may be performed to determine if there is a bleeding tendency or any other medical conditions that prevents the person from undergoing the procedure
  • Blood work, glucose, and pregnancy tests (if applicable) will be undertaken per physician recommendations
  • If anesthesia team is involved in the procedure; then, they too will discuss details of anesthesia with risks for complications and obtain permission from the patient (informed consent)
  • Avoid application of any deodorant or topical medicines on the area, prior to the procedure
  • It is advisable to quit smoking and the use of any nicotine-based products for a while, before the procedure
  • Consumption of alcoholic drinks must also be avoided for a period of time, as instructed
  • Individuals with diabetes, hypertension, or other cardiac conditions are required to discuss these (including medications taken) with their attending physician well in advance
  • For individuals with diabetes, it is important that the blood sugar stays within the normal range. If not, their diabetologist may have to control blood sugar by recommending insulin and/or a combination of oral medicines

Pregnant women and individuals with severe underlying sicknesses are advised not to undertake this procedure.

In case of minors and individuals unable to give informed consent, the parent or legal guardian or next of kin can sign the consent for the procedure.

What Tests are needed, before the Subcision surgical procedure?
