In cases where curvature is significant (usually indiciated by the ability to comfortably have sexual intercourse), some men choose to undergo a surgical procedure. Surgery should not be considered where the condition is not entirely stable, as further changes to curvature post surgery will negate undergoing surgery to begin with. As a general rule, you should be painfree for six months and not undergoing further physical changes before you consider this option. Waiitng 9-12 months would not be unwise.
There are several different approaches to sugery and the condition of your penis typically dictates the procedure you will undergo. Plication is typically carried out on men with a less prounced curve, and the grafting surgeries are more suited to men with curves over 40 degrees.
Plication - This is typically seen as a less invasive and more straightforward surgical option than others, and involves shortening the convex side of the curvature (so essentially not touching the scarred side at all). It involves placing stitches opposite of the PD scar resulting in the penis being straightened, or thereabouts. This type of treatment cannot treat bottleneck or hourglass deformaties, it is used to treat simple curvature. As with many procedures, improvements are made to the procedure over time. This is true of plication, and Dr Lue's 16 dot technique, is a slightly updated version of the procedure.
Incision and Grafting and Excision and Grafting - With "Incision and Grafting", shallow incisions are made in the scar tissue. This is done to open up the plaque somewhat. A graft (autologous or synthetic) is used to effectively patch up these incisions. In "Excision and Grafting" the scar tissue is actually removed and replaced, again with a graft. With grafting satisfaction is typically high, but for a minority of men erectile dysfunction can become an issue, as well as loss of sensitivity. There are various oral treatments for ED though, and for many men these are effective.
Penile Implant Surgery - For cases where erectile dysfunction is not helped by testosterone injections, viagra and other ED treatment options, penile implant surgery may be the only available route.
Depending on the surgery in question, loss of length may occur during the procedure. Therefore some men attempt to minimise this by using a traction or vacuum device for several months in order to stretch the scar tissue and reduce curvature somewhat before undergoing surgery. In much the same way, men often use vacuum therapy after surgery in order to exercise the penis and reduce any scar tissue and ED issues that may develop post surgery.
