Aspiration of a Ganglion
A nonsurgical method of treating a ganglion is to drain the fluid from (aspirate) the ganglion sac.
Your doctor can do this in the office using the following procedure:
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 doctor 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
