Treating Scars Part II: Types, Case Study, Treatment, Review

Injury necessitates urgent restoration of structural integrity and function to prevent complications like fluid loss and infection. Wound healing attempts to reorganize injured tissues, but perfect repair without scars—termed regeneration—is limited to embryonic stages or certain tissues like bone and liver.

Types of Scars

1. Normal Mature Scars: Typical outcome of wound healing.
2. Immature Scars: Early healing phase with active remodeling.
3. Hypertrophic Scars: Raised scars within wound boundaries.
4. Keloid Scars: Extends beyond wound boundaries, prone to itchiness and pain.
5. Atrophic Scars: Depressed scars, common after acne.

Scar Treatment Options

Scars vary widely, and treatments are tailored to their type:

• Topical Treatments: Limited evidence supports their efficacy; e.g., Vitamin E and onion extracts.
• Chemical Peels: Useful for atrophic scars, promoting collagen remodeling.
• Corticosteroid Injections: First-line for hypertrophic and keloid scars, despite potential side effects.
• Silicone Sheets: Non-invasive option for scar flattening, supported by anecdotal evidence.
• Dermal Fillers: Effective for atrophic scars, enhancing skin contour.
• Microneedling: Stimulates collagen for improved skin texture and scar reduction.
• Laser Therapy: Ablative and non-ablative lasers for scar remodeling.

Case Study: Hypertrophic Scar Treatment with PRP

Patient Profile: Female, 36, with hypertrophic scar post-cervical discectomy.

Treatment Plan:

• PRP (Platelet-Rich Plasma): Chosen over steroids due to scar location and prior unsuccessful treatments.
• Procedure: Centrifuged autologous blood processed into PRP, injected intradermally and subdermally.
• Outcome: Significant scar improvement noted after initial treatment; further sessions planned.

Review of PRP Treatment

• Follow-up: Scar flattening and reduced erythema observed; patient satisfied with initial outcomes.
• Further Sessions: Second PRP session resolved remaining imperfections, scar appeared smoother and less noticeable.

Conclusion

Effective scar treatment involves a tailored approach considering scar type, patient history, and treatment goals. Techniques like PRP show promise for scar remodeling, offering patients improved aesthetic outcomes and enhanced quality of life. Ongoing research is essential to refine treatment protocols and expand options for scar management.
