Ganglion Cyst Removal
Ganglion cyst removal, or ganglionectomy, is the removal of a fluid-filled sac on the wrist or finger. These cysts are attached to a tendon or a joint through their fibers and contain synovial fluid, which is the clear liquid that lubricates the joints and tendons of the body. Surgery is indicated only when the growth is so large that it is causing problems with the functioning of the hand or fingers. There are two methods for dealing with these benign growths.
Aspiration
-
An 18- or 22-gauge needle attached to a 20–30-mL syringe is inserted into the cyst. The doctor removes the fluid slowly by suction.
- The doctor may inject a corticosteroid medication into the joint after the fluid has been withdrawn.
- A compression dressing is applied to the site.
-
The patient remains in the office for about 30 minutes.
Excision
Some ganglion cysts are so large that the doctor recommends excision. This procedure also takes place in the physician's office with local or regional anesthetic.
Ganglion cyst removal process:
- The physician palpates, or feels, the borders of the sac with the fingers and marks the sac and its periphery.
- The sac is cut away with a scalpel.
- The doctor closes the incision with sutures and applies a bandage.
- The patient is asked to remain in the office for at least 30 minutes.
-
A bulky dressing, with or without a splint, may cover the area where you had the cyst to protect it.
After surgery
-
You should avoid strenuous physical activity for at least 48 hours after surgery.
- Report any signs of infection or inflammation to their physician.
- A follow-up appointment may be scheduled within three weeks of aspiration or excision.
