Dorsal carpal ganglion is one of the most common benign tumors of the hand. Many treatment modalities had been proposed and yielded the same success rate. In the present study, the authors conducted a randomized controlled trial to compare the success of treatment between surgery and aspiration combined with methylprednisolone acetate injection plus wrist immobilization. There were 28 patients enrolled and randomized into two treatment groups. Only 24 patients were available for the final follow up at 6 months. According to the present study, dorsal carpal ganglion was more common in females (83.3%) at an average age of 30 years. Pain was the most common presenting symptom (58.3%). The success by excision was 81.8% and by aspiration combined with methylprednisolone acetate injection plus wrist immobilization was 38.46%. The p-value was 0.047 by Fisher exact test. The present study has clearly shown that surgical excision gave a better success rate in the treatment of dorsal carpal ganglion.
