A ganglion will often disappear on its own after a year or two. If your ganglion is not causing much trouble, it is best to leave it alone.
The fluid can be taken out of the ganglion using a needle. This improves any discomfort for a while. Your doctor may also inject the ganglion with a steroid (cortisone). These treatments may help for a short time.
A variety of anaesthetic techniques is possible. The operation usually takes between a quarter of an hour and half an hour.
Your surgeon will make a cut over the ganglion and separate the ganglion from the nearby tendons, nerves and blood vessels. They will then remove the ganglion.
