Wrist and hand ganglion treatment with hyaluronidase injection and fine needle aspiration: a tropical African perspective.

In an attempt to provide an alternative non-invasive treatment to surgical excision of ganglion cysts of the hand, and as part of the departmental audit resulting from the prevailing economic depression, 340 consecutive patients with 349 ganglia were treated in a prospective investigation by intralesional injection of hyaluronidase (up to 150 units in 1 ml) followed by fine needle aspiration (FNA) of the cyst to dryness. Pressure was applied over a piece of gauze and maintained with a crepe bandage for 24 h. Of the 340 patients treated in this way, the vast majority (323 or 95.0%) were considered to be cured on clinical examination at 6-month follow-up; only 17 patients (5.0%) exhibited recurrence during this period and these were successfully treated by re-aspiration. To the knowledge of this author, this is the first report of the use of the enzyme hyaluronidase as an adjunct to FNA in the treatment of ganglion cysts of the hand. The results clearly show that this method of treatment is a safe, fast, well accepted and cost-effective alternative to surgical excision, which is relatively expensive and is known to be associated with certain complications, including hypertrophic scars and cheloids.
