Treatment of Digital Mucous Cysts with a Single-Layer Integra^® Dermal Regeneration Template

A Case Series

抄録

Distal mucous cysts (DMCs) occur in the distal interphalangeal finger joints or the interphalangeal thumb joints. Current treatment regimens include surgical cyst excision, which may involve skin flap elevation. More recent approaches include osteophytectomy or joint capsule removal (with or without cyst excision). In the present case series, the authors excised five DMCs with thinned skin, conducted osteophytectomy when necessary, and then covered the wounds with the Integra^® Dermal Regeneration Template-Single Layer (IDRT-SL) system. There were no postoperative complications, including limitation or deterioration in the joints' range of motion, and recurrence was not detected. The cosmetic outcomes were excellent. This may reflect the ability of IDRT-SL to facilitate untrammeled epithelialization and reduce myofibroblast activity, thereby limiting wound contracture. While IDRT-SL is relatively costly, it is considered cost-effective due to the length of the procedure (15 min), low recurrence rates, fast healing, and favorable appearance. Therefore, simple excision and coverage with IDRT-SL may be a beneficial treatment option for DMCs.
