About this study

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.

Inclusion criteria

  • Adult Patients (> 20-years old) with posttraumatic facial scar

Exclusion criteria

  • other types of scars (e.g; postacne scars), pregnancy, lactation, bleeding or coagulation disorders, liability for keloid formation, history of kobnerization, and patients with systemic diseases (cardiac, chronic renal diseases, chronic liver diseases, asthma and hypertension) at the time of recruitment.

Treatment and study plan

cannula- based subcision

Procedure

Insertion of a needle into the base of a cutaneous scar to cut fibrous tissue and help new collagen formation.

common- needle based subcision

Procedure

Insertion of a cannula into the base of a cutaneous scar to cut fibrous tissue and help new collagen formation.

Primary outcomes

  1. Vancouver scar scale (VSS)

    Time frame: 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) .
