IMPROVEMENT OF HYPERTROPHIC SCARS WITH INTRALESION INJECTIONS OF HYALURONIDASE.

Area of Science:

• Dermatology
• Wound Healing
• Regenerative Medicine

Background:

• Extra-uterine wounds typically heal with scarring, often resulting in hypertrophic scars.
• Various conservative and surgical treatments exist to manage unsightly and hypertrophic scars.
• Hyaluronic acid is a key component of the extracellular matrix involved in scar formation.

Purpose of the Study:

• To evaluate the efficacy of intralesional hyaluronidase injection for improving hypertrophic scars.
• To explore the mechanism by which hyaluronidase impacts scar tissue.
• To present clinical findings from patients treated with hyaluronidase for post-surgical hypertrophic scars.

Main Methods:

• A clinical review of patients with hypertrophic scars was conducted.
• Patients received intralesional injections of the enzyme hyaluronidase.
• The study focused on scars primarily resulting from tumor resection.

Main Results:

• Hyaluronidase digests high-molecular weight hyaluronic acid into low-molecular weight fragments.
• These fragments are associated with stimulating angiogenesis (new blood vessel formation).
• The treatment also demonstrated activation of mesenchymal stem cells, contributing to tissue remodeling.

Conclusions:

• Intralesional hyaluronidase injection is a promising method for the treatment of hypertrophic scars.
• The enzyme's mechanism involves breaking down hyaluronic acid, promoting regenerative processes.
• This technique offers a potential therapeutic strategy for improving scar appearance and function.
