Keloid Treatment Recommendations
Intralesional triamcinolone acetonide (10-40 mg/mL) is the first-line treatment for keloid removal, with higher concentrations (40 mg/mL) recommended for established keloids, and surgical excision should be reserved for refractory cases but must be combined with postoperative radiation therapy to prevent recurrence. 1
First-Line Conservative Management
Intralesional Corticosteroid Therapy
- Triamcinolone acetonide is the most commonly used and effective corticosteroid for keloid treatment, with concentrations of 10-40 mg/mL depending on lesion characteristics 1
- Higher concentrations (40 mg/mL) are specifically recommended for hypertrophic scars and keloids 1
- Response rates show 50-100% regression, though recurrence occurs in 33% at 1 year and 50% at 5 years 2
- Triamcinolone demonstrates faster and more effective response compared to verapamil, though with higher complication rates 2
Pain Management During Injection
- Use a 1:1 mixture of 1% lidocaine with epinephrine rather than topical EMLA cream, as this provides significantly better pain relief during and after corticosteroid injection 3
- Inject with a 26G needle to minimize discomfort 3
Monitoring for Adverse Effects
- Watch for local adverse effects including atrophy, pigmentary changes, telangiectasias, and hypertrichosis 1
- Assess for systemic absorption with repeated injections 1
Adjunctive First-Line Therapies
Silicone Sheeting and Pressure Therapy
- Silicone elastomer sheeting, taping to reduce skin tension, and pressure dressings are evidence-supported first-line treatments 4
- These can be used immediately after trauma in high-risk patients to prevent keloid formation 4
Combination Therapy for Enhanced Results
Triamcinolone Plus 5-Fluorouracil
- The combination of 5-FU and triamcinolone is more effective than either agent alone and shows fewer undesirable effects 2
- While 5-FU alone achieves comparable outcomes to triamcinolone alone, it causes more frequent side effects 2
Triamcinolone Plus Verapamil
- This combination proves effective with statistically significant overall improvements and long-term stable results 2
Surgical Excision: High-Risk Without Adjuvant Therapy
Critical Caveat About Surgery Alone
- Surgical removal of keloids poses a high recurrence risk unless combined with postoperative radiation and/or standard therapies 4
- Surgery alone should never be performed due to the high recurrence rate 4
Surgery Plus Radiation Protocol
- When surgery is necessary for refractory keloids, combine surgical excision with postoperative irradiation followed by immediate intralesional triamcinolone if any signs of recurrence appear 5
- This combination achieved complete cure in 56% of keloids without additional treatment, and 89% showed good results with additional conservative treatment 5
- This represents the most effective approach for forcing keloids into remission 5
Alternative Therapies for Refractory Cases
Laser Therapy
- Laser therapy alone carries a high recurrence rate and should not be used as monotherapy 2
- Better results occur when combining CO2, pulsed-dye, or Nd:YAG lasers with triamcinolone intralesional injections 2
Cryotherapy
- Reserve cryotherapy for smaller lesions only 4
Emerging Options
- Intralesional verapamil, fluorouracil, bleomycin, and interferon alfa-2b injections appear beneficial for established keloids 4
- Imiquimod upregulates interferons that inhibit collagen production by fibroblasts 1
- Pulsed dye laser and imiquimod cream are alternative postsurgical options for refractory scars 4
Prevention in High-Risk Patients
Risk Factor Identification
- Patients younger than 30 years with darker skin are at highest risk 4
- Sternal skin, shoulders, upper arms, earlobes, and cheeks are most susceptible sites 4
- Body piercings trigger keloid formation in approximately 2.5% of ear piercings 6
- Strong genetic predisposition exists, with patients having personal or family history facing significantly elevated risk with any skin trauma 6
Preventive Strategies
- Individuals with personal or family history of keloids should be cautioned about any procedures causing skin trauma, as prevention is the best strategy 1
- Implement immediate silicone elastomer sheeting, taping to reduce skin tension, or corticosteroid injections when trauma is anticipated 4
- Watch for infections, which can be treated with standard topical or systemic antibiotics 1
Common Pitfalls to Avoid
- Never perform surgical excision without planning for postoperative radiation therapy and close monitoring for early recurrence 5
- Do not rely on over-the-counter herb-based creams, as evidence is mixed, and there is little evidence that vitamin E is helpful 4
- Avoid laser therapy as monotherapy due to high recurrence rates 2
