Main symptoms
- Soft, mobile swelling on the dorsal or volar wrist
- Size may vary over time (enlarges with activity, decreases with rest)
- Often painless, but large cysts can cause pressure pain
- Hospital stay
- No hospital stay required, same-day discharge.
- Recovery time
- 2–4 weeks
- Return to work
- Return to desk work in 3-7 days, light hand work in 2 weeks, heavy hand work in 4-6 weeks.
Ganglion cysts are benign (non-cancerous), fluid-filled, gel-consistency swellings arising from joints or tendon sheaths. They are most commonly seen on the dorsal or volar wrist. They are 3 times more common in women than men. Ganglions are harmless and not life-threatening, but can cause cosmetic concerns or movement-related pain.
Symptoms
Typical findings:
- Soft, mobile swelling on the dorsal or volar wrist
- Size may vary over time (enlarges with activity, decreases with rest)
- Often painless, but large cysts can cause pressure pain
- In some cases, tenderness with joint movements
- Reduced hand strength (in large cysts)
Diagnostic Methods
Diagnosis is usually made by clinical examination. Typical location, soft consistency, and transillumination (light passing through) are characteristic of ganglions. Ultrasound confirms the cyst contains fluid and shows vascular/nerve proximity. MRI may be needed for unclear cases or deep-seated cysts.
Treatment Approach
Non-Surgical Treatments
Treatment options include: watch and wait — about half regress spontaneously within 6 months to 2 years; aspiration — drainage with needle; simple but high recurrence rate (50-70%). Old methods like striking the wrist are no longer recommended (risk of nerve and tendon injury).
Surgical Treatment
Surgical treatment removes the cyst with its root (excision). It can be done open or arthroscopically. The arthroscopic method provides better cosmetic results with small incisions and allows joint evaluation. Recurrence after surgery is 5-10%, much lower than aspiration.
Surgical Process
Performed under regional or local anesthesia, lasting 30-45 minutes. A 2-3 cm incision is made over the cyst, and the cyst is removed with its root.
Hospital Stay
No hospital stay required, same-day discharge.
Recovery Process
- First 3-5 days: Splint use, swelling control
- Week 1: Suture removal, light finger movements
- Weeks 1-2: Wrist range exercises
- Weeks 2-4: Return to full activity
Return to Work
Return to desk work in 3-7 days, light hand work in 2 weeks, heavy hand work in 4-6 weeks.
Potential Complications
Generally a very safe surgery. Rare complications: recurrence (5-10%), nerve injury (usually temporary), scar hardening, motion restriction (resolves with rehabilitation).
Frequently asked questions
Can ganglion become cancerous?
No, ganglion cysts are 100% benign. Cancerous transformation is not a concern. However, any suspicious swelling must be evaluated by a specialist.
Will it disappear on its own?
Yes, about half regress spontaneously within 6 months to 2 years. Watch-and-wait is appropriate for painless cysts not affecting function.
Should cysts be smashed for treatment?
No, this old method is no longer recommended. Striking the cyst can damage nerves and tendons, and recurrence is high.
