We present the case of a female patient with complications from superficial implantation of polydioxanone spiculated threads in the facial middle third. The manifestations were edema, ecchymosis, superficial palpation of the thread and skin plication. For the treatment we propose a novel protocol of clinical degradation of polydioxanone threads, using hyaluronic acid injecting it into the implantation area of the polydioxanone threads. Non-cross linked hyaluronic acid was infiltrated along the path of the thread. The follow-up at seven, 21 and 45 days showed decreased edema, folds and skin irregularities due to wire traction and attenuation of secondary rhytides. A sample of the thread in hyaluronic acid was observed in a laminar flow campaign evidencing degradation at 72 hours. Administering hyaluronic acid was effective in inducing clinical biodegradation of the thread suggesting that non-crosslinked hyaluronic acid is a powerful catalyst for the hydrolytic degradation of polydioxanone.
