Summary

This study compared three allograft materials for penis girth augmentation, finding no significant differences in infection or graft loss rates among AlloDerm, Belladerm, and Repriza. Surgeons should consider these findings when selecting allografts for phalloplasty.

Area of Science:

  • Urology
  • Plastic Surgery
  • Regenerative Medicine

Background:

  • Allograft use is increasing in reconstructive surgery, particularly for penis girth augmentation (phalloplasty).
  • Different allograft manufacturers employ distinct preparation methods, leading to varied material properties.
  • Limited comparative data exists on the performance of various allografts in phalloplasty procedures.

Purpose of the Study:

  • To compare the clinical performance of three different allograft materials used for penis girth enhancement.
  • To evaluate infection rates, wound exposure, and graft loss associated with AlloDerm, Belladerm, and Repriza.
  • To provide data-driven insights for surgeons selecting allografts in phalloplasty.

Main Methods:

  • A retrospective review of 47 patients undergoing circumferential allograft penis girth enhancement.
  • Graft materials included AlloDerm (n=9), Belladerm (n=20), and Repriza (n=21).
  • Data collected included material type, infection, wound exposure, and graft loss.

Main Results:

  • Overall infection (graft exposure) occurred in 42% of patients (20/47).
  • Graft exposure or loss occurred in 3/9 AlloDerm, 9/20 Belladerm, and 8/21 Repriza patients.
  • No statistically significant differences were found among the three allograft types regarding infection or graft loss.

Conclusions:

  • Despite differing preparation methods, AlloDerm, Belladerm, and Repriza demonstrated similar infection and graft loss rates in phalloplasty.
  • The study suggests that allograft material choice may not significantly impact outcomes in this specific surgical application.
  • Surgeons should consider these findings when selecting allografts, as performance appears comparable across these brands.
