About

This study aims to evaluate the effectiveness of cannula- based subcision versus common needle subcision in treatment of posttraumatic atrophic facial scars

Full description

In addition to cosmetic issues, atrophic scars can lead to psychological issues like social isolation, low self-esteem, and embarrassment. Subcision (Subcutaneous incision-less surgery) has been used for years to treat a variety of skin depressions, including atrophic acne scars and other depressed scars. Numerous modifications have been made throughout time to this surgical method to make it easier and more efficient. Although needle subcision is a straightforward, simple, useful, and practical procedure, it has many side effects and the overall success in this procedure is mild to moderate. So, in this study we evaluated the effectiveness of cannula- based subcision versus common needle subcision in treatment of posttraumatic atrophic facial scars.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

50 participants in 2 patient groups

Cannula arm

Active Comparator group

Description:

the cannula's 18 gauge tip was pointed upward and approximately parallel to the skin's surface when it was put into the superficial dermis, 1-2 millimeters away from the targeted scar. In order to completely remove fibrous tissue from the superficial dermis, a lancing motion (linear inserting-withdrawing needle action) was utilized first.

Treatment:

Procedure: cannula- based subcision

Needle arm

Active Comparator group

Description:

The needle's 27 gauge tip was pointed upward and approximately parallel to the skin's surface when it was put into the superficial dermis, 1-2 millimeters away from the targeted scar. In order to completely remove fibrous tissue from the superficial dermis, a lancing motion (linear inserting-withdrawing needle action) was utilized first.

Treatment:

Procedure: common- needle based subcision
