Background:
Injection of calcium hydroxylapatite filler may result in nodule formation owing to superficial placement of the filler. Calcium hydroxylapatite nodules are difficult to reverse. Previously reported therapeutic options are limited and include intralesional triamcinolone, massage, needling, and excision, each with inconsistent results or potential for scarring.
Observation:
We have observed complete resolution of calcium hydroxylapatite nodules after a single treatment with fractional carbon dioxide laser.
Conclusions:
A single session of fractional carbon dioxide laser treatment may resolve selected cases of calcium hydroxylapatite nodules. The mechanism of action may involve conversion of the product into tricalcium phosphates which dissolve readily. This novel therapeutic technique may enhance treatment options for a difficult clinical problem.
