Clarify Scarring Opinion

In an answer to a previous post, you wrote:
“Only about 5% of former patient developed noticeable scarring. Most of these scars are the result of the healing properties of the patient, although some are technique dependent.”

But another top hair restoration practice, Hasson & Wong, asserts a different view:
“The single most important factors in donor scarring is the ability of the surgeon to excise the strip and close the wound from the donor site correctly. The ability of the individual to “heal well” is much less important except for a very small percentage of individuals who either heal with keloid formation or have an abnormality of collagen formation.” (from their website)

My questions are, how can two leading medical groups in the field hold such seemingly polar-opposite opinions? And, do you base your assertion on anecdotal observations, or have formal studies been published on this topic?

Much of what I say about scars is based upon: (1) anecdotal observations that I am constantly researching on my patients, and (2) direct measurements on patients whose scars I have measured before and after repairs.

I do not agree with you that our two statement are polar. I always assume that doctors are all competent and the techniques are all consistent between doctors. I know that is not always true, but I generally like to believe that doctors try their best to do their best. When it comes to wound closure, it is not rocket science. I am a surgeon by training, so I am more qualified to make that statement then others who did not invest the years of training and experience that I have. With that said, both of us are in agreement. I suspect that Drs. Hassan and Wong are not making the same assumption on the uniformity of techniques in the first place.
