I've been researching dorsal wrist ganglion cysts and trying to find more information on treatment outcomes, both in terms of recurrence and incidence of complications. I found a good review article, but unfortunately I can only see the abstracts for most of its references.
My main question:
The rates for spontaneous resolution and recurrence after treatment with aspiration both appear to be near 50% (with a pretty wide variability of reported outcomes.) This suggests that it may be difficult to tell the difference between a ganglion that would've resolved on its own vs. one that was was only resolved due to aspiration. Are there any studies that attempt to address this?
Is there any information on the reported duration of ganglion cysts in the case that they do spontaneously resolve? I imagine this is complicated by lack of follow-up by patients when the problem goes away.
Are there any reported complications due to aspiration of dorsal ganglion cysts? I found a reference to a 5% complication rate in a referenced article from the survey (abstract here), but this was for palmar ganglia. Lacking more specific data, are there known complications for aspiration procedures in general?
