Clinical effect of penile lengthening and augmentation with autologous granular fat graft on short penis

Abstract

Objective To evaluate the effectiveness and safety of autologous granular fat graft applied for penile lengthening and augmentation. Methods After all the superficial ligment and 1/3-2/3 part of the deep suspensory-ligament had been cut off for penile lengthening, local pedicaled fascia-adipose flap was designed to fill the depression, the pre-centrifuged autologous granular fat was injected into the space beneath Buck's fascia for penile augmentation. Normal length, pulling penis length, diameter, circumference and complications were evaluated. Results 34 cases were performed and followed up for 3-18 months, both ideal length and diameter increase of penis were achieved. The differences of nomal length, pulling-length, the diameter and circumference were (2.8±0.1) cm, (2.1±0.2) cm, (0.9±0.1) cm, (2.8±0.1) cm, respectively. The common complications included poor wound healing in 4 cases, preputial edema and subcutaneous scleroma in 8 cases for 3 months. Conclusions Autologous granular fat graft for penile augmentation during the lengthening surgery is a reliable and effective method and easy procedure. Detail processing can decrease the complications. Key words: Penile lengthening; Penile augmentation; Fat particles, autologous; Fat fascia flap
