A ganglion cyst is a fluid-filled swelling that usually develops near a joint or tendon. Many ganglion cysts do not require treatment. However, if the cyst is painful, causes numbness or tingling, or interferes with function, the doctor may recommend an operation if your symptoms are not relieved by non-surgical treatment.

The Procedure

1. The operation can be performed under local or general anaesthesia.
2. An incision is made near the ganglion.
3. Tendons, nerves and blood vessels are moved to one side and the ganglion is removed.
4. The incision is closed with stitches and a sterile dressing is applied.

Before the Procedure

1. A written consent is required.
2. Inform doctors about drug allergy, your regular medications, or other medical conditions.

After Procedure

1. Keep the wound dry and clean. Follow doctor’s and nurse’s advice on wound care.
2. Stitches will be removed or dissolved in 2 weeks.
3. Please comply with the medication regime as prescribed by your doctor.
4. Elevate the affected limb either using a sling or a pillow for the first few days to reduce swelling and prevent any accidental knocks.
5. A heavy manual job requires you to be off work for a few weeks longer.
6. The wound is covered with waterproof dressing when you are discharged. Do not remove it unless you are told to do so. Always keep the dressing clean and dry.
7. Immediately consult your doctor or return to hospital for professional attention in the event of severe wound pain associated with redness and swelling, secretion of pus, massive bleeding, shivering or fever over 38°C or 100°F.
8. Any follow-up consultations should be attended as scheduled.
