: Wound care specialist says “it has healed too much, now it can’t heal” I had three surgeries this summer, the last surgery was 11 weeks ago. The incision is small, about 2 inches, and started to heal fine at one end.

“the wound has healed too much, and now it can’t heal anymore without knocking it back first.” I asked for more details and got a similar response back.

Talking to patients is an art. This doctor lacks that art to some extent.

Wounds left to heal on their own - without stitches - heal by secondary intention, that is, the wound fills in with a temporary tissue called granulation tissue. The best outcome is that enough granulation tissue is laid down to cover the wound, then, within the tissue, the normal components of skin, such as epithelial tissue and blood vessels grow.

Epithelialization and neovascularization result from the increase in cellular activity. Stromal elements in the form of extracellular matrix materials are secreted and organized. This new tissue, called granulation tissue, depends on specific growth factors for further organization to occur in the completion of the healing process. This physiologic process occurs over several weeks to months in a healthy individual.

However, this is somewhat of a "dance" dependent on how much of what kinds of signals the injured tissue sends out, and sometimes the granulation tissue grows too much, and actually impedes the process of epithelialization. In that case, the excess granulation tissue (or even all of it) needs to be removed so the process can start over (the process is dependent on the right amount of the right signals (e.g. growth factors).

This is what was meant by the doctor.

As to why silver nitrate was used, it destroys granulation tissue, but so does just picking it off and other methods.

Your wound specialist really should have this talk down pat enough to give the answer in under a minute. But patients ask questions, and time is getting shorter and shorted for doctors to spend with patients (blame insurance companies for that.) So one way to save time is to avoid answering questions. You'll heal just as well without the information, but it doesn't engender much trust in the doctor.

What is reported here about the "wound care specialist" sounds like being either badly phrased by the doctor or misunderstood, misremembered or phrased rather unluckily by the OP (no offence, just speculation).

Whatever the reason for this unsatisfactory status of explanation: This treatment is likely not focused on the nitrate part of the formulation alone.

Silver nitrate is likely employed to help with the healing process. Quotes from the links:

[#]
Topical application of silver nitrate is often used in wound care to
help remove and debride hypergranulation tissue or calloused rolled
edges in wounds or ulcerations. It’s also an effective agent to
cauterize bleeding in wounds. Silver nitrate is a highly caustic
material, so it must be used with caution to prevent damage to healthy
tissues.

[#]
Whether it is used as a topical ingredient or a dressing ingredient,
the use of silver in treating wounds has been around for quite some
time. Silver has an array of beneficial effects in promoting healing.

[#]
The use of silver nitrate application reduce dramatically the size of
large wounds, which eventually healed, avoiding the patients to
undergone surgery.
