Trachea shave can be done by any experienced ENT doctor in your area. It can also be performed by most surgeons who do FFS. An issue for doing it with ENT doctor is the incision is mostly made right above the adams apple, which leaves you with a visable scar, on the area which constantly moves while you talk. Most capable FFS surgeons do the incision higher, under the chin, which makes it practically invisible, (and they probably also have better skills for closure of incision, than the average ENT doctor.). Risks are quite serious, if this procedure is done by someone who is not capable and experienced of doing it (for example, you would convince your local famous plastic surgeon to do it...). Other than that it's a risk free simple procedure which can be done under the local anesthesia.
