Objective To summarize the effect of free skin graft for repairing scrotal avulsion injury, and to investigate the repair impact of the method on spermatogenesis. Methods Between June 2001 and June 2010, 8 cases of complete avulsion injury of the scrotal skin were treated with the free skin graft, aged 22 to 64 years (mean, 29 years). The causes of injury included machine twisting in 4 cases, animal attack in 3 cases, and traffic accident in 1 case. The time between injury and hospital ization was 1-7 hours (mean, 3.5 hours). Five cases compl icated by avulsion of penile skin, 3 by perineal laceration
with exposure of testes and spermatic cord, and 1 by avulsion of leg skin. Results After 10 days, 80% to 95% grafted skin
survived. The reconstructed scrotum had shrinks and the wound healed by first intention after dressing change. Eight patients were followed up 12 to 24 months (mean, 16 months). At last follow-up, the patients had relaxed and droop scrotum, and penile erection was normal. Semen qual ity analysis showed: semen volume of 2-6 mL (mean, 4.2 mL); complete l iquefaction with l iquefaction time of 15-30 minutes (mean, 23 minutes); sperm density of (12-27) × 106/mL (mean, 16 × 106/mL); sperm motil ity of 45%-65% (mean, 56%); and sperm motil ity (grade A) of 25%-42% (mean, 32%). Conclusion Complete avulsion of the scrotal skin can be repaired by free skin graft, which has no significant effect on spermatogenesis.
