Dermatologist Use of Intralesional Triamcinolone in the Treatment of Acne.

OBJECTIVE

Despite common administration of intralesional triamcinolone to acne lesions, there is little published data or consensus on best practices. This study aimed to evaluate specific characteristics of intralesional triamcinolone for acne among various dermatology healthcare professionals.

DESIGN

One hundred participants (82 attending physicians, 9 physician assistants, 8 other healthcare professionals, and 1 unidentified) from private practices and academic centers completed a 10-question survey to assess specific characteristics of intralesional triamcinolone injections, including frequency, indication, depth of injection, concentration, volume, as development of adverse events.

RESULTS

The most common reported concentration of intralesional triamcinolone was 2.5mg/mL (52.5%). The most frequently used volume injected was 0.05mL (42.3%). In total, 61.6 percent of those surveyed answered that they inject into the center of the lesion. Additionally, 50.5 percent of respondents counsel patients on potential adverse effects of hypopigmentation and atrophy before every injection. The majority of respondents (88.8%) reported that less than one percent of their patients returned for adverse events resulting from triamcinolone usage, and 48.4 percent reported that atrophy lasted over six months (48.4%).

CONCLUSION

The data collected from this study can offer guidance on best practices in administering intralesional kenalog to patients. While consistency exists for the concentration of triamcinolone used, there was significant discordance in the volumes and depth of triamcinolone injection. Observed skin atrophy rates are extremely low, but they are long lasting when it occurred. We can use these data to refine our treatment techniques as well as improve treatment outcomes and patient satisfaction.
