Summary
This is a split-scar study with a target sample size of 20. There are two interventions: fractional erbium:YAG-assisted drug delivery of 5-fluorouracil and fractional erbium:YAG-assisted drug delivery of triamcinolone acetonide. Patients will undergo treatments in a series of 4 treatments at approximately 4 week ± 1 week intervals. Investigators will monitor for safety and continued benefit after the end of the interventional treatment.
