Visualization of the wrist ganglion capsule by methylene blue staining as an aid for complete resection in children.

PURPOSE To evaluate the effectiveness of methylene blue staining during ganglion resection in children, to assess ganglion resection and minimize recurrence. METHODS From August 2007 to March 2011, 36 children with dorsal or volar wrist ganglions with an average size of 2 cm (range, 1-4 cm), including 5 recurrent cases, underwent resection performed with intraoperative methylene blue marking of the cyst wall. RESULTS We found recurrence in one patient after 2 years; no obvious complications were observed in any patient. CONCLUSIONS Methylene blue staining of the ganglion during resection may be helpful for achieving complete resection. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic II.
