Background:
Reconstruction of perineal defect is challenging. The goal of reconstruction is to maintain normal function with good esthetic outcomes. Coverage of the perineal defect is often difficult with one loco-regional flap when the size of defect is very extensive. In this article, clinical applications of the propeller posteromedial thigh perforator (PMTP) flap for extensive perineal defects were described.
Patients And Methods:
Eight patients underwent perineal reconstruction with propeller PMTP flaps from March 2013 to December 2018. The average age of the patients was 65 years (range: 52-80 years). The causes of the defects included infection and skin cancers. The perforator was a branch of deep femoral artery. The flap was harvested as a perforator-based flap and rotated 180° to the defect area (propeller flap design).
Results:
The average flap size was 256.5 cm2 (range: 136-400 cm2 ) and average follow-up period was 22.4 months (range: 6-48 months). All flaps survived after surgery without major complications. The donor sites were all primarily closed and the patients were all satisfied during the follow-up period.
Conclusion:
The propeller PMTP flap is an adequate new option for reconstructing extensive perineal defects. The flap avoids the need for microanastomosis and replaces the defect with similar tissue.
