Subsection is a minor surgical procedure used to treat scars and skin wrinkles. Subsection is performed using a special subcutaneous needle that is inserted through a hole in the surface of the skin. The sharp edge of the needle is used to break the fibrotic filaments that connect the scar to the underlying tissue.
The release of fibrotic fibers and the deposition of new collagen resulting from wound healing lead to scar healing. Subsection can be safely performed on an outpatient basis.
The decision to have a subsection depends on the type, location and severity of the wound.
Subcutaneous may be used to treat the following:
Sunken scars (due to acne, trauma, surgery)
* Excluding deep ice scars
What are the contraindications?
Subsection may not be appropriate in the following conditions:
Patients with a history of hypertrophic or colloidal scars
Users of systemic oral retinoids (within 12 months) (such as acitretin, isotretinoin)
Bleeding or blood clotting disorders (blood clotting)
Active bacterial or viral infection
How is subjection done?
The area to be treated is cleaned to remove dirt and makeup
The edges of the scar may be marked with a surgical marker that adjusts the light above the head to mark the dimples.
A local anesthetic is injected.
A sharp-tipped needle or a sharp-edged needle is inserted at an acute angle near the scar and sloping up and parallel to the skin surface. Smaller needles may be used for small wounds and superficial wrinkles.
The needle travels through the dermis and moves back and forth in a fan-like motion. Knocking is heard when the fibrous bands are cut deep into the dermis and deep under the skin.
The needle is rotated 90 degrees and re-moved through the skin scar with a fan-like motion (subening finning).
To prevent the formation of a large hematoma due to bleeding, the needle is removed and compressed circumferentially around the exit point.
Manual pressure is applied to the wound for a few minutes.
Immediately after subsection:
Pressure and ice are applied to the surgical site to maintain homeostasis and reduce the risk of bleeding.
Some doctors recommend antibiotics and anti-inflammatory drugs.
How many sessions of treatment are needed?
People have different abilities to form collagen (scar tissue). The number of subgenes required depends on the type, location and severity of the skin problem.
Three to six visits are enough for an average Oscar. Intervals of at least one month between treatments are usually recommended.
