@otavares I am a spine surgery patient for cervical stenosis. Depending on where your stenosis is will determine how the surgeon will address it. If you have stenosis at the nerve roots between the vertebrae that are narrowed due to bone growth, a surgeon may use an ultra- sonic type scalpel for trimming bone to widen those areas. If you have stenosis in the central canal, and your spinal cord is being compressed, that is a lot more difficult to access, and usually there is a bad or collapsed disc involved that will be removed to allow access to the canal. That may be removed by a different tool that takes bites out of the disc. That leaves a space that must be filled with something such as a bone disc implant in a fusion or an artificial disc implant.

When you start consulting surgeons, you must keep an open mind and listen to their recommendations. They have their own ways of working and their own preferred tools and procedures. If you go in with an expectation of them using an ultra sonic cutting tool, and it isn't what they offer to you, you may be on a slippery slope. No surgeon wants to be told how to do their job because you found some information on the internet. You certainly can ask how they do their procedures. Keep in mind it is very easy for surgeons to back out of helping a patient for a lot of reasons. They don't want to get into a situation of getting bad online reviews over a disagreement with a patient and take a risk on surgery.

Sometimes surgeons do advertise a "miracle tool" claiming it makes them a better surgeon, but that is marketing. The best facilities will also have the latest in technology and tools, so they likely have the ultrasonic scalpel. I know Mayo does have it. Here is a discussion where the ultrasonic scalpel was talked about.

The best reason to choose a surgeon is their reputation and skill and if their area of interest matches what you need. They all have statistics of their own person success rates with the procedures that they do. Also look at the reputation of the medical facility where they work. You can find a lot of information in their profiles about their training and awards. You'll find excellent surgeons teaching at spine surgeon conferences for doctors and publishing medical research papers.

We have many discussions about cervical stenosis. If you type those keywords in the search bar at the top of the screen, you will find many patents talking about their surgery experiences.
