Scar; Atrophy
Conditions
Brief summary
This study aims to evaluate the effectiveness of cannula- based subcision versus common needle subcision in treatment of posttraumatic atrophic facial scars
Detailed 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.
Interventions
PROCEDUREcannula- based subcision
Insertion of a needle into the base of a cutaneous scar to cut fibrous tissue and help new collagen formation.
PROCEDUREcommon- needle based subcision

TREATMENT
Masking
SINGLE (Outcomes Assessor)
Masking description
The assessor was blinded to the treatment applied to each half of the scar.
Intervention model description
Each scar was split into two equal halves; the upper right half were treated using a cannula- based subcision approach, while the lower left half was treated using a common needle-based procedure

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Vancouver scar scale (VSS) | 4 months | The (VSS) examines vascularity, pliability, pigmentation, and height, yielding a total score that ranges from 0 to 14. The original rating system was as follows: Vascularity (0=normal, 1=pink, 2=red, 3=purple), Pliability (Normal=0, Flat=0, Supple=1, Yielding=2, Firm=3, Ropes=4, Contracture=5), Pigmentation (0=normal, 1=hypo-pigmentation, 2=mixed pigmentation, 3=hyper-pigmentation), and Height (Flat=0 \<2 mm=1 2-5 mm=2 \>5 mm=2) . |
