Effective Treatment of Small Uncomplicated Skin Abscesses with Fire Needle: A Case Series

BACKGROUND: Uncomplicated skin abscesses are collections of pus within the skin structure and are usually caused by bacterial infections. Clinically, they are quite common and inevitably affect people of any age. The current management strategies comprise prompt initiation of antibiotics and incision and drainage. However, pain and the long healing process of skin lesions can cause distress to a lot of patients. Fire needling is a characteristic treatment in traditional Chinese medicine (TCM) and has proven effective in treating skin abscesses. Moreover, fire needle therapy has a more desirable cosmetic outcome in contrast to surgical debridement. The purpose of the study is to demonstrate the rapid, effective, minimally invasive, and better cosmetic outcomes of fire needles in the treatment of uncomplicated skin abscesses. METHODS: A total of 10 patients, aged between 1 and 45 years, with skin abscesses, were recruited. All patients who fulfilled the inclusion criteria with lesions less than 4 cm in diameter were topically treated with mupirocin ointment twice a day after fire needle therapy. If the lesion was still purulent after 2 days, it was treated again with fire needle therapy. The efficacy was assessed by a 4-grade scale at 2 days, 1 week, 2 weeks, 4 weeks and 12 weeks post-fire needling. RESULTS: Lesions with a diameter of less than 2 cm achieved significant remission (SR) or partial remission (PR), after 2 days post-treatment and reached complete remission (CR) or significant remission (SR) after 1 week following treatment. Meanwhile, lesions with a diameter of 2–4 cm achieved PR after 2 days and were assessed as CR or SR 1 week after post-fire needle therapy. None of the patients had a recurrence within 12 weeks after treatment. CONCLUSION: Fire needle therapy is a promising treatment method for uncomplicated skin abscesses smaller than 4 cm, which warrants further in-depth and more large-scale studies.
