Ganglion Cyst Removal
in Rockhampton

What is going on

A ganglion cyst is a fluid-filled outpouching from a joint capsule or tendon sheath, most commonly on the back of the wrist (dorsal scapholunate ganglion), the front of the wrist near the radial artery (volar ganglion), or at the base of a finger (flexor tendon sheath ganglion / 'pearl ganglion'). The cyst contains thick mucinous fluid — not pus, not tumour — that has leaked from a small defect in the joint capsule and become walled off. Patients describe a soft, sometimes-tender lump that can change size with activity. Around half of all ganglia resolve spontaneously over months or years; another fraction settle with aspiration alone. Surgery is reserved for the minority with persistent symptoms, mechanical problems, or diagnostic uncertainty.

Not sure if this is the right diagnosis? The wrist pain hub triages the differential by anatomical location.

What the operation involves

**Open ganglion excision** removes the cyst together with its capsular stalk — a 2–3 cm incision over the cyst, identification of the capsular origin, and excision of both. Excising the stalk (rather than just the cyst) reduces the recurrence rate; recurrence is around 5–10% with adequate stalk excision and around 30–40% with simple cyst aspiration. **Arthroscopic excision** is offered for selected dorsal-wrist ganglia and avoids a visible scar. The procedure is typically done under regional or general anaesthesia as a day case, takes around 30 minutes, and is followed by a soft dressing. Full clinical detail is on the education page, and the wrist ganglia education page covers the underlying condition.

How this case is handled

The practice's standard pathway for a wrist ganglion is: confirm the diagnosis (clinically or with imaging if needed), explain the natural history (many resolve), and discuss the options — observation, aspiration, or surgical excision. For most patients, observation or aspiration is the right first step. Surgery is offered for persistent symptomatic ganglia, recurrent ganglia after aspiration, or where the diagnosis is uncertain. Ruby Doolan at Extend Rehabilitation provides post-operative hand therapy for selected cases — most patients do not need it.

Fees, Medicare rebates and the surgery-quote process are on the fees page. The case for seeing a fellowship-trained surgeon — and what fellowship training adds — is set out separately. GPs can find the referral pathway, urgency triage and what to include in the letter on the referrer page.

What this operation is billed under

The procedure is covered by the following Medicare Benefits Schedule items. Surgeon, anaesthetist, assistant, hospital and prosthesis fees are quoted separately and in writing before surgery — see the fees page for the practice's quote process and an explanation of why surgical fees follow the Australian Medical Association schedule. Surgery does not proceed without itemised written informed financial consent.

Patient questions we hear most

• Should I have my ganglion removed?

  Most ganglia do not need surgery. About half resolve on their own over months or years, and another fraction settle with one or two aspirations. Surgery is worth considering when the ganglion is causing persistent pain, interfering with grip or wrist movement, pressing on a nerve, or where the diagnosis is uncertain. Cosmetic concern alone is usually not a strong indication for surgery — the visible scar after excision can be more conspicuous than the lump it replaces. The consult walks through the trade-offs and the patient decides.

• What's the difference between aspiration and surgical excision?

  Aspiration is a clinic-based procedure where the cyst is drained with a needle and syringe; sometimes a steroid injection is added. It's quick, inexpensive, and resolves the cyst in around 30–50% of cases at first attempt. The recurrence rate is high — around 50–70% — because the underlying capsular defect is not closed. Surgical excision removes the cyst plus its stalk through a small incision; it has a much lower recurrence rate (around 5–10%) but requires a day case operation, anaesthesia, a small scar and a few weeks of recovery. Aspiration is a reasonable first step for most ganglia; surgery is reserved for those that recur or are particularly bothersome.

• Will the ganglion come back after surgery?

  Recurrence after open excision with adequate stalk removal is around 5–10%. Recurrence is more likely with smaller incisions that don't allow full visualisation of the stalk, with arthroscopic technique in inexperienced hands, or when the underlying joint pathology (e.g. scapholunate instability) is not addressed. The surgical technique used at the practice prioritises seeing and excising the stalk — that is what determines recurrence rate, more than incision size or technique choice.

• How long is the recovery?

  Most patients are back to office work and light activity in a few days. Driving is reasonable once the wrist is comfortable, usually within a week. Manual or gripping work is held off for two to four weeks while the joint capsule heals. Sport with impact (tennis, golf, manual lifting) is reasonable at four to six weeks. The wrist may feel tight or sensitive over the scar for a few weeks; this settles with gentle massage and gradual use.

• Are ganglion cysts dangerous?

  Ganglion cysts are benign — they are not tumours and they do not turn into cancer. Concern usually arises because of an unfamiliar lump, particularly in patients without a previous history of one. Where the lump has unusual features — rapid growth, hardness, fixity to deeper tissues, or skin changes — imaging (ultrasound or MRI) is requested before any treatment to confirm the diagnosis. Most lumps that look like ganglia turn out to be ganglia, but the consult includes the differential diagnosis and what would prompt biopsy rather than excision.

• How much does ganglion surgery cost? What does Medicare cover?

  Open ganglion excision is performed under regional or general anaesthesia as a day case at Mater Private Hospital Rockhampton, so a separate anaesthetist gap applies on top of the surgeon and hospital fees. The practice quotes the surgical fee in writing before booking — Medicare item, rebate and out-of-pocket gap shown separately. Most major funds offer no-gap arrangements. Surgery does not proceed without itemised written informed financial consent.
