Aspiration of a ganglion

A nonsurgical method of treating a ganglion is to drain the fluid from (aspirate) the ganglion sac.

Your health professional can do this in the office using the following procedure:

• The ganglion area is cleaned with an antiseptic solution.
• A local anesthetic is injected into the ganglion area to numb the area.
• When the area is numb, the ganglion sac is punctured with a sterile needle.
• The fluid is drawn out of the ganglion sac.
• The ganglion collapses.
• A bandage and, in some cases, a splint are used for a few days to limit movement and prevent the ganglion sac from filling again.

Treating a ganglion by draining the fluid with a needle may not work because the ganglion sac remains intact and can fill again, causing the ganglion to return. For this reason, your health professional may puncture the sac with the needle 3 or 4 times so the sac will collapse completely. Even then, the ganglion is likely to come back.

Infection after draining the ganglion fluid is a possible complication of this procedure.

Ganglions on the wrist may return in up to 9 out of 10 people using nonsurgical treatment, such as aspiration.¹
