Perineal reconstruction using a bilobed pudendal artery perforator flap

Area of Science:

• Reconstructive surgery
• Plastic surgery
• Gynecologic oncology

Background:

• Perineal reconstruction requires specialized techniques due to distinct tissue characteristics and functions of the urogenital and anal triangles.
• Pudendal artery perforator flaps offer a versatile solution for complex perineal defects.
• A bilobed flap design enhances flap mobility and arc of rotation, crucial for covering wide and deep defects.

Purpose of the Study:

• To evaluate the efficacy of bilobed pudendal artery perforator flaps in perineal reconstruction.
• To assess the functional and aesthetic outcomes of this reconstructive technique.
• To determine if the bilobed flap design preserves the unique characteristics of the perineal triangles.

Main Methods:

• Retrospective analysis of 15 female patients undergoing perineal reconstruction.
• Application of pudendal artery perforator flaps, with a focus on bilobed designs.
• Evaluation of defect characteristics, flap design, and clinical outcomes.

Main Results:

• All flaps demonstrated successful survival throughout the follow-up period.
• Flap sizes varied, with an average follow-up of 4.6 months.
• Reconstructed areas exhibited favorable functional and aesthetic results, with bilobed flaps used in most cases.

Conclusions:

• The bilobed pudendal artery perforator flap is an effective method for perineal reconstruction.
• This technique successfully preserves the functional, morphological, and cosmetic integrity of the perineal region.
• Tailoring flap design to defect location and shape is key to optimal outcomes.
