Ganglion Cyst

What is a Ganglion Cyst?


Ganglion Cysts, also known as Mucous Cysts, are small sacks of fluid which emanate from a joint or tendon sheath (tunnel).  They typically present as an asymptomatic bump in the skin, but at times cause discomfort.


How does one diagnose a Ganglion Cyst?


A Ganglion has a fairly typical appearance, and forms at one of a few common sites, including either side of the wrist or at the end of one of the fingers.  A Ganglion that forms at the end of a finger will occasionally deform the adjacent finger nail.  It is usually not necessary to obtain special tests, such as an ultra sound or MRI, to diagnose a ganglion.


What is the treatment for a Ganglion Cyst?


Ganglion Cysts may be left alone, treated with aspiration, or treated with surgical removal.  In most instances a ganglion does not cause discomfort.  If a patient desires, the ganglion may simply be observed.  Not infrequently they will rupture on their own in response to trauma.  Aspiration followed by gentle compression for three weeks yields a 40% cure rate. Dr. Steven Shoen performs aspiration  in the office under local anesthesia at the initial office visit.   The recurrence rate following surgical removal is under 10%.  Dr Shoen performs surgical removal of a wrist Ganglion at one of the local surgery centers under an “arm block” with sedation.  Following surgery patients are permitted to carry out light activities immediately and strenuous tasks after three weeks.   Dr. Shoen carries out removal of a finger ganglion under local at his office procedure room.
