Dr. Herazy, I wrote you last month and you really helped my confidence with what I am doing. Is it possible that my PD scar is like a piano wire from the base to the head? That is the only irregularity I can find. Thanks Dick R.
Yes, it is certainly possible that your scar feels like a piano wire. The Peyronies plaque or scar material presents in a wide variety of ways, just as most everything about PD seems to be variable.
Although you did not say so, I will guess the long ridge of scar material tissue you say feels like a piano wire is located on the top or dorsal surface of the shaft. This is a very common location for long narrow PD scars. It is the anatomical structure, called a septum, where the tunica albuginea of the two chambers meet in the mid-line, and it runs from the base of the penis to the head (glans). This septum is especially susceptible to separation during trauma, and can consequently develop a long thin scar.
You can assume this is your only, or your primary, Peyronie's scar if your curved penis is directed upward.
While you might be correct that it is only as thin as a piano wire, I suggest that you examine this thin ridge again to determine if you can detect that it tapers down to a flat band. Almost like the gable roof of a house, your piano wire structure might just be like the uppermost ridge of the roof that gets thinner as it slopes down laterally. I mention this speculation because it is always beneficial to have a clear and accurate visualization of each scar so you can closely monitor it for changes as you continue to treat your PD.
You might find, if I am correct, that this flat tapered surface on either side of the piano wire will undergo changes in size, shape, density and surface features as your scar deteriorates as your treatment progresses.
If you do not know it is there, you will not have this useful information available to you to guide your treatment. You must try to know everything there is to know about each of your Peyronies scars.
