• PURPOSE
    • To evaluate the results of a single surgeon's treatment of mucoid cysts, comparing outcomes between injection and surgery.
  • METHODS
    • One hundred thirty-four cysts were treated, with a minimum 2-year follow-up period. Thirty-one patients had nail ridging or deformity at presentation. Eighty patients had multiple soft-tissue punctures into the cyst with a 25-gauge needle and injection with local anesthetic and steroid. Fifty-four patients had surgical excision and joint debridement.
  • RESULTS
    • In the injection group, complete resolution of the cyst occurred in 48 cases (60%). Among the 32 that recurred, repeat injections were performed in 8 cases; 3 resolved. No recurrences were noted in the surgery group. Nail ridging resolved after surgery in 25 digits; the remaining 6 digits had partial improvement or persistent ridging. Five infections occurred and were treated successfully with antibiotics (4) or debridement (1), or both.
  • CONCLUSIONS
    • Aspiration and injection was convenient but had a 40% recurrence rate. Surgery provided definitive treatment with no major long-term problems.
