Well why can’t any surgeon here in Canada pull the meat out between the bread? Seems like a simple procedure, yet nobody even suggests it?
To address your question of 'then, why don't the NA doctors pull meat from sandwich', it's because a 'COULD BE' isn't a diagnosis of what it is. They would have to diagnose what ever med condition or name of it was something where the muscle somehow got trapped somewhere in vicinity of bone cut OR was just put somewhere where now the muscle has less FREEDOM than prior. This 'incarceration' relates to SOMETHING. It's just that it doesn't relate to a type of usage of that term with your NE doctors
I'm just trying to help 'brain storm' what this could be given the term 'muscle incarceration'. So, it could be muscle kind of 'stuck' between the bone cut. But within a 'could be' scenario, there is always a 'couldn't be'.
Another 'could be' that wouldn't be nerve damage would have to do with re-attaching everything back (muscle, ligament, tendon connections, whatever) after they detach when making dissection inside mouth to move the chin. So, do they re-attach exactly where they were before they detached or do they have to change where they attach to somewhere else due to chin being moved somewhere else than prior? I don't know.
So, we (well not me) don't know exactly what this is. Only what it could be. However, we DO know that through the incision inside the mouth below your lip, things were detached and later had to be attached somewhere. Also, when patients complain of lower tooth show subsequent to getting a chin implant where the incision is through inside of mouth, a PS (who does not put them in via inside mouth) does an operation to re-attach to a better place.
Again, IDK exactly what it is other than to suggest you engage your Canadian docs about the possibility of IF the structures they DETACHED and attached or re-attached after the surgery have something to do with your complaint. So, 'incarceration' could have something to do with the muscles not having the FREEDOM of function they used to have subsequent to their being put somewhere where they lost it. But your NE docs are not going to 'relate' to the
incarceration term because it's probably not in their med lingo to use it the way the Indian doctor is.
I would also suggest you ask the Indian doctor if his operation will involve DETACHING the muscle connections from where they were attached during your surgery and re-attaching elsewhere for better function.
