Ganglion cyst excision (finger, hand)
Ganglion cysts on the fingers or hand are fluid-filled lumps that form near a joint or tendon, most often at the base of a finger or over the back of the hand. When a cyst causes pain, restricts movement, or keeps growing back, surgical excision removes it along with its stalk to reduce the chance of recurrence.
For information specifically about digital mucous cyst excision, or excision of flexor tendon sheath ganglions, please see those specific pages.

Surgical removal of a ganglion cyst arising from a joint or tendon sheath
A ganglion (ganglion cyst) is a common, non-cancerous lump that arises from a joint or tendon sheath in the wrist, hand or fingers. Surgical excision removes the cyst at its base, where it arises from the underlying joint or tendon.
Who is this procedure for?
- People with a painful or functionally troublesome ganglion cyst
- People whose ganglion has not resolved on its own and who would like it removed
- People who have had a ganglion recur after previous aspiration and want a more durable option
- Not necessary for asymptomatic ganglions, which do not have to be removed
What does the surgery involve?
An incision is made over the lump, and the ganglion is removed at its base, where it arises from the underlying joint or tendon. The surgery is performed as day case surgery. A less invasive alternative – drainage, aspiration or puncture of the ganglion – can be performed by a radiologist under ultrasound guidance, though recurrence is significantly more likely after aspiration than after surgical excision.
Alternatives to surgery
Surgical excision is one option for a ganglion cyst. Depending on your situation, the alternatives may include:
- Doing nothing for now (watchful waiting): ganglia may vary in size, or resolve, of their own accord, and do not have to be removed
- Non-surgical management: splinting, or needle aspiration of the cyst as an office procedure – a lower-risk option, though recurrence is more likely than after surgical excision
- A different procedure: wrist ganglions and finger/hand ganglions are excised somewhat differently and have different rehabilitation – Dr Tomlinson will tailor the approach to the location of your ganglion
What happens if left untreated: ganglions are not dangerous, but may persist, enlarge, or continue to cause discomfort or restrict movement.
Dr Tomlinson will discuss which options suit you at your consultation. For further explanation, see the Finger and Hand Ganglion Cysts page.

Frequently Asked Questions
Where will my surgery be done?
At the Avenue Hospital.
Why might I choose local anaesthetic rather than sedation or a general anaesthetic?
A procedure under local anaesthetic avoids the risks and recovery of sedation or a general anaesthetic. You don’t need to fast beforehand, you can eat and drink normally, you recover quickly, and you usually go home soon afterwards. For many people it’s also less expensive and more convenient.
How much time will I need to have away from work?
This depends on what your job involves and where the ganglion was located. If your work is desk-based or administrative, you may be able to return relatively soon, often with some temporary modifications. If your work is physical – heavy lifting, manual labour or “on tools” – you’ll usually need longer. As a guide for this procedure, most people return within days to a week; there is a bandage on your hand that needs to be kept dry for one week after surgery.
When will I be able to drive again?
Multiple things affect this: which hand was treated, whether you’re wearing a bandage, whether you can grip the wheel and respond safely in an emergency, whether you are driving for personal or commercial purposes, the nature of the vehicle you are driving, and your pain levels and medications. You also need to be safely in control of the vehicle for insurance purposes – you should be able to grip the steering wheel strongly with both hands and be able to take evasive action in an emergency before you get behind the wheel. As a guide: plan not to drive for one week after the procedure, although many individuals will be able to drive within 24 hours.
When can I do a full day of administrative or desk work?
Within 1 day to 1 week, particularly with some temporary adjustments (see below). Keeping your hand elevated and taking regular breaks helps reduce swelling and discomfort in the early days. If you need to drive to work or carry or lift objects as part of your administrative work then alternate or half days may be a prudent measure when first returning to work.
What workplace modifications might help?
Depending on your job, helpful temporary modifications can include:
– Half days or alternate days to begin with
– No heavy lifting
– Lighter duties or being off tools
– More frequent breaks
– Using a headset instead of holding a phone
– Voice-to-text or dictation instead of typing
– Keeping the hand elevated at your workstation
– Avoiding repetitive gripping
– Help with carrying or moving items
– Moving temporarily to reception or phone duties if your role is normally manual
– Protecting the wound if your work exposes your hands to water or contamination (e.g. food handling, healthcare, wet trades)
We’re happy to provide a letter for your employer outlining recommended modifications.
I take a GLP-1 medication (such as Ozempic, Wegovy, Mounjaro or Trulicity) — how does this affect my procedure?
GLP-1 medications, used for diabetes or weight management, slow the emptying of the stomach. This can increase the risk of stomach contents being present during sedation or a general anaesthetic. In line with current ANZCA guidance, if you’re having sedation or a general anaesthetic you’ll be asked to follow a clear-fluid-only diet for 24 hours before your procedure, followed by the standard 6-hour fast. Please tell us and your anaesthetist that you take this medication – your anaesthetist will give you specific instructions. If your procedure is under local anaesthetic only, fasting is generally not required, but please still let us know.
How long will I need to wear a splint?
A bandage is worn over the surgical site until your first post-operative visit, approximately 1 week after surgery. Not all ganglions require a splint after this time; Dr Tomlinson will advise you at your initial appointment whether a protective splint is recommended to facilitate your return to normal activities after the bandage is removed.
Will I need to see a hand therapist afterwards? May I see one if I'd like?
You’re welcome to see a hand therapist if you’d find it helpful, particularly if stiffness develops. If Dr Tomlinson recommends that you wear a thermoplastic splint to protect your finger after the initial bandage is removed then she will advise you of this at your first appointment. Silicone compression finger sleeves or “stalls” (also sometimes called finger cots, finger caps and digital sleeves) can also be of assistance in protecting your incision site once the initial bandage is removed.
What pain medication will I need afterwards?
Simple pain relief – paracetamol and ibuprofen – is usually all that’s needed. We can always prescribe stronger painkillers if you need them.
Risks & complications
General risks of hand surgery
- Bleeding and bruising; rarely, a collection of blood (haematoma) that may need draining
- Infection, which may require antibiotics or, rarely, further surgery
- Pain — usually temporary, occasionally persistent
- Swelling – common, and usually settles over weeks to months
- Scarring – scars are permanent and occasionally become thickened, raised or sensitive
- Allergic reaction to the local anaesthetic, antiseptic, dressings, tape or suture material
- Delayed or problematic wound healing
- Stiffness or reduced movement in the fingers, hand or wrist
- Injury to nerves, causing numbness, altered sensation or, rarely, a painful neuroma
- Injury to blood vessels (arteries)
- Injury to tendons
- Injury to bone (fracture)
- Failure to fully relieve your symptoms, or symptoms returning over time (recurrence)
- Complex regional pain syndrome (CRPS) – an uncommon but significant condition causing ongoing pain, stiffness and swelling
- Cold intolerance – the hand becoming more sensitive to cold, usually improving with time
- The need for further surgery
- Blood clots in the leg or lung (DVT/PE) – uncommon in hand surgery, with a slightly higher risk after a general anaesthetic or prolonged immobilisation
Specific risks of this surgery
- Recurrence of the ganglion, which can occur even after apparently complete excision
- Irritation or temporary injury to the nearby digital nerve or artery, given how closely these ganglions sit to them
- Stiffness of the finger or tenderness over the scar
- Restricted finger movement in the early recovery period, usually resolving with time
Anaesthetic
If you are having sedation or a general anaesthetic for this procedure, your anaesthetist will discuss the specific risks of anaesthesia with you separately.
Recovery & rehabilitation
First 48 hours
Keep your hand elevated ( in a sling if necessary) for 48 hours to reduce bleeding and post-operative swelling. Local anaesthetic lasts 6–24 hours (occasionally 1–3 days); your hand will have numb areas during this time.
First week
Keep the dressing dry and intact until your post-operative review. You may use your hand for light activities, but listen to your hand and avoid anything that causes pain, such as lifting or gripping. Scar sensitivity and discomfort with lifting and gripping are expected in the first few weeks. Listen to your hand and do not perform activities that cause discomfort. You should find that your discomfort improves each day if you are looking after your hand.
Second week
You will no longer have a bulky bandage over your finger or hand. You can get the area wet in the shower and wash your hands, but you should protect the incision site from trauma and keep the area dry at most times. Restrictions on movement and use will depend on where the ganglion was located, and therefore what impact, if any, movement has on the skin and joint healing.
6 weeks
Most incisions are able to tolerate normal activities after three weeks. Deep-pressure tenderness over the wound can persist for some months. The scar will feel tight and firm. Massage assists with improving scar mobility and minimising scar firmness.
3 months
The scar firmness will start to resolve after 3 months, and will take up to 12 months to settle.
Long term
Recurrence can occur with either aspiration or surgical excision, though it is significantly less likely after surgical excision. There is no guarantee that removing the ganglion will resolve any pain that was attributed to it.
