What Surgery for Ganglions and Cysts Can Achieve
A ganglion is a fluid-filled cyst that arises from a joint or tendon sheath. It contains a thick jelly-like material and may fluctuate in size. Ganglions can cause discomfort, restrict movement or place pressure on nearby structures.
A mucous cyst is a type of ganglion that forms near the end joint of the finger. It may be associated with nail changes if it affects the area where the nail is formed.
The aim of surgery is to remove the cyst in its entirety, reducing the risk of recurrence and improving symptoms and overall hand function.
Your Surgical Journey
Your surgical journey begins with a comprehensive consultation with Dr Collins at The Surgery. This provides time to assess your symptoms, examine your hand and discuss your goals and expectations in detail.
Surgical excision of ganglions and mucous cysts is typically performed as a day procedure under local or general anaesthetic, depending on the size and location of the cyst. The cyst is removed along with its connection to the underlying joint or tendon sheath. In some cases, particularly with mucous cysts, a local flap may be required to close the wound.
Recovery and Aftercare
Some swelling, stiffness and tenderness are expected after surgery. A splint may be required in the early post-operative period to support the hand and protect the surgical site. Hand therapy is often recommended to help restore movement, strength and function.
Driving is usually possible after one to two weeks, once you can safely control the vehicle and perform emergency manoeuvres comfortably. Return to work depends on the nature of your role. Desk-based work is often possible within one to two weeks, while more physically demanding roles may require a longer recovery period.
Is Surgery Right for You?
You may benefit from surgical excision if a cyst is causing pain or discomfort, restricting movement or interfering with daily activities.
A consultation with Dr Collins allows for a personalised assessment of your symptoms and function, and an opportunity to discuss the most appropriate management approach for you, including whether surgery is indicated.

Frequently Asked Questions
Ganglions are benign cysts that develop from the lining of a joint capsule or tendon sheath and contain a thick, gel-like fluid. They may change in size over time. A mucous cyst is a type of ganglion that occurs near the end joint of the finger and can sometimes affect the nail, causing ridging or deformity.
Both types of cysts can be managed surgically. The site and size of the cyst determine whether local or general anaesthetic is used. The cyst is removed in its entirety along with its connection to the underlying joint capsule or tendon sheath. In some cases, particularly with mucous cysts, a local flap may be required to close the wound.
Surgery is considered when a cyst is causing pain, restricting movement, interfering with daily activities or increasing in size.
Ganglions and cysts are benign and may not require treatment if they are not causing symptoms. Some may resolve spontaneously. Aspiration or steroid injection can be performed but are associated with a higher recurrence rate.
Some discomfort, swelling and stiffness are expected after surgery. A splint may be used in the early post-operative period depending on the site of surgery. Hand therapy may be recommended where required.
Return to work depends on the nature of your role. Desk-based work is often possible within one to two weeks, while more physically demanding roles may require a longer recovery period.
Driving is usually possible after one to two weeks, once you can safely control the vehicle and perform emergency manoeuvres comfortably.
All surgery carries some degree of risk. Potential risks include pain, bleeding, infection, adverse scarring, stiffness, nerve or vessel injury, complex regional pain syndrome, recurrence or the need for further surgery.
Recurrence is possible, although removing the cyst and its connection to the underlying joint or tendon sheath reduces this risk.
Yes. Outcomes vary depending on the site and size of the cyst, individual healing and adherence to post-operative care. Expected outcomes, risks and limitations are discussed in detail during your consultation.
