A surgical challenge: reconstruction of post Fournier’s gangrene large penoscrotal defects with pedicled Gracilis muscle flap

Background Large penoscrotal defects with exposed testis are a challenge to reconstruct. Muscle flaps provide an excellent option to reconstruct such defects. The aim of the article is to present the authors’ experience in using gracilis muscle flap in the reconstruction of penoscrotal defects following Fournier’s gangrene. Methods All patients with Fournier’s gangrene who underwent a soft tissue reconstruction using unilateral gracilis muscle flap from January 2013 to November 2018 were prospectively included in the study. Patients with exposed testis, penoscrotal defects and dead spaces to fill were included, and exclusion criteria were persistent infection, large defects requiring bilateral gracilis or expected shortfall of coverage using unilateral gracilis muscle. Postop aesthetic assessment was done using modified Vancouver Scar Scale (mVSS) after 6 months by an independent reviewer. Results Fourteen cases of post Fournier’s gangrene defects were reconstructed by using gracilis muscle flap with split skin graft in a tertiary care hospital. All were male patients. Age ranged from 20 to 72 years with mean age 35.5 years. After debridement and regular dressings, operation was done under general or spinal anaesthesia. All flaps survived well and there were no major complications encountered. All the patients had acceptable aesthetic outcomes on mean follow-up of 13.2 months. Conclusions The pedicled gracilis muscle flap with split skin graft is a good option for large defects involving penis, scrotum and perineum, especially in Fournier gangrene. This flap offers minimal donor site morbidity and minimal major complications with acceptable cosmetic outcomes. Level of evidence: Level IV, therapeutic study.
