Purpose: Numerous techniques have been introduced to reconstruct the perineal area in order to preserve function of both the recipient and the donor site while satisfying aesthetic results. There are several advantages of using the pudendal aretery perforator based flap in that it provides thin coverage of defect area and a relatively excellent circulation through perforators. The perineal region can be divided into two areas : the urogenital triangle and the anal triangle. Since each area differs in structure and function so does its reconstructive plan. The authors of this article report clinical results obtained from pudendal artery perforator based reconstructed cases according to each different triangles. Methods: A total of 15 patients who underwent perineal reconstruction were enrolled in our study from 2002 to 2006. There were 4 cases of vaginal cancer, 4 cases of extramammary Paget’s disease, 1 case of rectovaginal fistula in females and 2 cases of Paget’s disease and 4 cases of Fournier’s gangrene in male cases. The follow up period was on average 6 month. In female, superficial pudendal artery perforator based local flap were used to reconstruct the urogenital triangle defects, while internal pudendal artery perforator based local flaps were used to reconstruct the anal traingle defects. In males the gracilis myocutaneous flap and internal pudendal artery perforator based local flaps were used in reconstruction of the scrotum and perineal defect. Results: In females, there was 1 case of partial flap necrosis that employed the superficial pudendal artery perforator but secondary repair through the internal pudendal artery perforator based local flap was done. In addition, there were 4 wound dehiscence cases in females and 2 cases in males. Conclusion: We believe that a better aesthetic and functional outcome can be achieved in perineal reconstruction if discrete surgical planning is carried out systematically categorizing the choice of flap employed acccording to distinct anatomical regions : the urogenital and the anal triangle.
