Imagine if tens of thousands, eventually millions, of people are waving around their credit cards trying to find someone to take their money, service providers pop up to serve that need. It's not a perfect comparison, but LASIK created a whole new class of providers, separate from traditional ophthalmologists. It doesn't seem out of the realm of reason to suspect if this goes forward as an effective hearing treatment that some ENTs and Otologists will set up clinics which will specialize in the service.
Look at stem cell therapy for knees and backs, there is pretty weak data as to its efficacy, it's not FDA approved, insurance won't cover it but a Google search will show you stem cell clinics are all over the place. Actually this is a pretty equivalent situation in that you need an expert to administer it, it is pricy ($5000 and way up) and can often times require multiple treatments over the course of a few weeks.
I just believe if we are willing to pay someone, they will find a way to take our money.
