Ganglion cysts are fluid-filled cysts typically arising from joints and tendon sheaths of the hands and wrists (as well as elsewhere in the body). Although they are not generally dangerous they can be unsightly and painful and often patients request treatment. Needle aspiration involves puncturing and aspirating the cyst with a large needle. Unfortunately, the long term success of this technique is only thought to be around 10%. Operative excision of cysts results in roughly 90% success. Often cysts of the fingers can be removed in the office under local anesthesia. Removal of cysts arising from the wrist joint typically requires a trip to the surgery center or the hospital. Dr. Fremling has been providing the operative excision of cysts of the hand and wrist for over 20 years.
