A ganglion cyst is the out-pouching of the thin inner joint or tendon lining through the outer capsule, much like when the inner-tube of a bicycle tyre pops out of a defect in the outer tyre. The cyst is filled with lubricating fluid.
The simplest method to remove these is simply to aspirate the fluid and inject some cortisone into the cavity to collapse the cyst. Often this process has to be repeated a few times to stop the ganglion cyst from re-filling.
If the cyst does not respond at all to aspiration and injection, surgical excision may be required.
Surgical excision can be performed at CityMed under local anaesthetic in our purpose built procedures theatre.
