Pediatric Ganglion Cysts: A Retrospective Review.

Background: Ganglion cysts are the most common type of soft tissue tumors of the hand. In the pediatric population, monitoring may be appropriate unless cysts are painful, interfering with range of motion or parental concerns exist. Reported recurrence rates after surgical removal of pediatric ganglion cysts vary widely in the literature. Notably, recurrence rates are higher for children than adults, ranging from as low as 6% to as high as 35%. Methods: A retrospective review was performed of a single pediatric hand surgeon's patients undergoing excision of primary and recurrent ganglion cysts from 2010 to 2015. Variables measured included patient age at diagnosis of ganglion cyst, time to presentation, location of cyst, hand dominance, previous therapy, previous surgery, length of surgery, tourniquet time, length of follow-up, any associated complications, and recurrence of cyst. Results: Ninety-six patients were identified with an average age of diagnosis 10.2 years. Indications for surgery: 95.8% for pain or decreased range of motion, 4.2% for cosmetic or parental concern. About 75% of the cysts were dorsally located, with the remaining 24.2% being volar. A total of 5 (5.3%) recurrences were recorded. Tourniquet time was on average 9.8 minutes longer for cases that resulted in recurrence. Multivariate analysis of the data demonstrated a 25% increased risk of recurrence with patients who had a previous aspiration. Conclusions: This is a retrospective review of a single pediatric hand surgeon's outcomes of pediatric wrist ganglion cysts. Our recurrence rate of 5.3% is low for a pediatric population indicating potential merit in this surgeon's operative and postoperative techniques. We demonstrate significantly increased rates of recurrence when a cyst had been previously aspirated, possibly indicating scarring and disruption of planes resulting in difficult dissection, increased tourniquet times, and incomplete excision.
