Treatment: No therapy is required for small, asymptomatic ganglion cysts. If a patient desires removal or if the cyst is causing symptoms, especially weakness and numbness, therapy is needed. Needle aspiration is often used as a first-line treatment option; a pressure bandage is applied to try to keep the cyst from reexpanding. After the aspiration, intralesional injection of triamcinolone is used to try to scar the lining of the cyst. This has shown excellent results. If aspiration and injection are not successful, surgical excision is necessary. It is important to have a hand surgeon evaluate and treat these cysts because of their proximity to multiple vital nerve and tendon structures.
