Innervated and vascularized radial thenar flap free grafting for partial penile reconstruction after traumatic penile amputation: a case report and surgical techniques.

ABSTRACT: Penile amputation is a rare deformity mostly resulting from self-mutilation, felonious assault, or accidental trauma, and penile reconstruction or phalloplasty is necessary when microreplantation cannot be performed. Here we report a rare case of a 42-year-old man with traumatic penile amputation and describe surgical techniques for partial penile reconstruction by using a novel innervated and vascularized radial thenar flap free grafting method. Excellent cosmetic and functional results were reported with no severe complications of dysuria, urethral stricture, and urinary fistula were observed during the 23 months of postoperative follow-up time. It is believed that innervated and vascularized radial thenar flap free grafting is an acceptable treatment option for patients with traumatic penile amputation.

Project description:INTRODUCTION:Prosthesis-assisted penile reconstruction has been performed extensively to restore a cosmetically acceptable phallus. However, a large number of patients will undergo revision surgery for various prosthesis-related complications. AIM:To develop a 1-stage prosthesis-free dynamic cavernosa reconstruction method using bilateral innervated gracilis muscles and to investigate the feasibility and reliability of the surgical design. METHODS:10 fresh cadavers were dissected to assess the availability of bilateral gracilis muscles for functional cavernosa rebuilding. 11 mongrel female dogs were involved in the penile reconstruction surgery. The neophallus consisted of bilateral gracilis muscles as the neo-cavernosa, a right gracilis skin flap as the neourethra, and a lower abdominal flap with an anterior rectus sheath as the skin envelope and neo-tunica albuginea. The function and structure of the neo-phalli were assessed 7 months postoperatively. MAIN OUTCOME MEASURES:The neurovascular pedicle length of the gracilis muscles and the volume of the gracilis venter musculi were measured in the cadaveric investigation. The average dimensions of the canine neo-phalli at rest and during electrostimulated erection were obtained and the muscular fatigue-resistant curve was drawn. Histologic evaluations also were performed. RESULTS:The neurovascular pedicle length and volume of the gracilis muscles were sufficient to yield a nearly normal appearance of the neo-cavernosa in the cadaveric and animal studies. The muscular fatigue-resistant curve demonstrated adequate length, stiffness, and duration of erection of the neo-phalli to accomplish normal coitus. Histologic evaluations showed an intact neourethra and nearly normal muscle structure in the inner layer of the canine neo-cavernosa, except for significantly increased amount of collagen fibers and type I/III collagen ratio in the outer layer of the neo-cavernosa. The percentage of type II (fatigue-prone) muscle fibers did not change significantly. CONCLUSION:Our preclinical investigation proves that corpora cavernosa reconstruction using bilateral innervated gracilis muscles is technically feasible and functionally efficacious.
