About Ganglion Cysts
Ganglion cysts are common lumps that appear on the hand and wrist which can fluctuate in size.
They are generally not painful but are often annoying due to their appearance.
The cysts typically occur at 4 sites:
- the back of the wrist (dorsal)
- the front of the wrist (volar)
- the base of the finger (flexor sheath)
- the end joint of the finger (mucous cyst)
Ganglion Cysts can usually be diagnosed by examination ie without x-ray. An ultrasound is often requested to confirm the diagnosis and may be helpful if the ganglion is very small or to help outline the full extent of the ganglion.
X-rays may be used to look for any arthritis or other joint problems.
If the ganglion is painless and not causing any problems it is feasible to let it be as it may even disappear spontaneously requiring no treatment.
Persistent ganglions which are becoming troublesome can initially be treated with a steroid injection as this can help reduce or eliminate the ganglion.
If the cyst remains after a steroid injection it can be removed surgically.
Surgery is performed by creating an incision directly over the swelling and removing both the ganglion and a small cuff of joint capsule from which the ganglion arises.
This is generally performed as a day surgery in hospital under general or local anaesthetic.
Where do ganglions most commonly appear?
Ganglions are most commonly present on the back or the front of the wrist and on the bone or end joint or the finger.
What are the main causes of ganglions?
Ganglions usually arise due to some degeneration in the lining of a joint in the hand or wrist.
When is an x-ray or ultrasound required to diagnose a ganglion?
Although most ganglions can be diagnosed by examination alone, an x-ray is useful if arthritis or other joint problems are suspected.
Often a request for an ultrasound is required to assist with diagnosis and possibly for a steroid injection at the same time.
Is it important to treat all ganglions?
No. If a ganglion is causing you no pain then there is no need to treat it – unless of course you are concerned due to its appearance.
Are there any non surgical options for treatment of ganglions?
Yes. Usually ganglions can be treated with a steroid injection prior to considering surgery as this sometimes helps to reduce and eliminate the ganglion.
How long is my recovery post surgery?
Surgery to excise ganglion cysts can be performed under general or local anaesthetic and is performed as day surgery in hospital.
The wound usually heals quickly and symptoms are often relieved within the first few weeks.
The dressing is kept in place for 5-7 days post surgery and patients can use their hands for gentle activities in the few weeks post surgery.
Is my ganglion likely to recur?
The average risk of return of a ganglion after surgical removal is around 10%.
Ganglion: An abnormal non cancerous swelling on a tendon sheath
Cyst: A closed sac-like structure that contains liquid gas or semisolid substance
