There is a lot of dialogue in the group on the benefits of selecting an experienced (or in fact highly experienced) implant surgeon. I share below an excerpt from the following paper: http://tau.amegroups.com/article/view/1459/2434
which specifically documents outcomes from surgeons of varying levels of experience. From my own experience with a surgeon that had done over 3500 surgeries, he measured my penis size as 19 cm during the surgery, but specifically chose to add a 20cm implant. He told me in pre-operation consultation that he would 'aggressively size the implant'. 12 months out the sizing and angle etc of the implant is spot on. There is no risk of tip (or base) erosion .. a consequence of an oversized implant.
The choice of surgeon is likely to have an impact on eventual penile length after PPI. A frequent implanter (widely considered as a surgeon who inserts more than 25 PPIs per year) is likely to use a longer PPI cylinder compared to an infrequent implanter. In an outcome analysis study comparing 57 penile prostheses implanted by a multiple surgeon group versus 57 penile prostheses placed by a single surgeon in a center of excellence (COE), Henry et al. found that the median cylinder length of implants placed by the COE surgeon was 2 cm greater than those placed by the multiple surgeon group (P<0.0001). More than 82% of implants placed by the COE surgeon had cylinders that were 17 cm or longer, with 37% having cylinder lengths between 20-22 cm. This was in contrast to the multiple surgeon group, whereby more than 55% of implants had cylinders that were less than 17 cm with only 14.3% having cylinder lengths between 20-22 cm. Median operative time was also considerably shorter for the COE surgeon (34 vs. 94 minutes, P<0.0001) (10).
