Abstract

Background
Various treatments exist for addressing volume loss in atrophic scars. Although laser therapy has gained traction in treating atrophic scars, it is associated with side effects, such as post-inflammatory hyperpigmentation or erythema. Additionally, not all types of atrophic scars respond optimally to laser therapy, even after multiple sessions.
Objective
This study aimed to evaluate the efficacy and safety of punch elevation for atrophic scars that yielded unsatisfactory outcomes after repeated laser treatment sessions.
Methods
Seven patients with atrophic scars on their facial area underwent punch elevation, concurrently supplemented by fractional CO₂ laser application to the scar margins. Improvement in volume restoration of atrophic scars was assessed via investigator evaluation and 3-dimensional (3D) image analysis.
Results
After 1 month, median volume (interquartile range) of depression improved from 4.39 mm³ (2.23∼9.90 mm³ ) to 1.97 mm³ (1.46∼7.50 mm³ ), indicating a statistically significant difference post-punch elevation (p=0.018). No serious adverse events were reported during follow-up.
Conclusion
The efficacy of the punch elevation was objectively evaluated. Punch elevation is a safe and effective therapeutic avenue for atrophic scars that exhibit resistance to laser or alternative interventions.
