Microsurgical Vascularized Free Temporoparietal Fascia Transfer for Peyronie's Disease: An Experimental Study

ABSTRACT

This experimental study on 24 male rats evaluated the advantages of vascularized vs. nonvascularized temporoparietal free fascia transfer as an improved form of penile tunica albuginea replacement. The paper describes in detail steps in these techniques and offers functional, anatomic, and histologic follow-up after 3 months. All 24 rats developed straight corpora cavernosa in erection. The flap was successful in each case, providing satisfactory morphologic appearance with minimal bulk. The only differences were histologically provided. Secondary degenerative changes were identified in all penises with nonvascularized fascial transfer, and one-third of penises with vascularized temporoparietal fascia free transfer. These results encourage vascularized free-tissue transfer application as an optimal solution in human penile reconstructive surgery.
