The application of keystone flap combined with vacuum-assisted closure in the repair of sacrococcygeal skin defect after tumor resection.

OBJECTIVE

We aimed to explore the efficacy of keystone flap combined with vacuum-assisted closure (VAC) in the repair of sacrococcygeal wounds.

METHODS

This study is a retrospective review of patients undergoing keystone flap reconstruction between January 2014 and January 2018. A standardized data collection template was used to collect related variables. The detailed process of the reconstructive surgery is carefully described in this study. The postoperative healing process was closely observed.

RESULTS

Twelve patients underwent keystone flap repair between January 2014 and January 2018. The average wound size before closure measured 7.83 ± 1.93 × 5.28 ± 0.91 cm. All the patients achieved primary wound healing and the flaps survived during the follow-up period, which ranged from 1 to 24 months. No severe complications and obvious scar appeared, and the patients were satisfied with both appearance and function.

CONCLUSIONS

The application of keystone flap combined with VAC is a promising way to repair wounds in the sacrococcygeal region with little postoperative complication and similar soft-tissue thickness to the surrounding tissue.
