The field of otology is currently going through the same "boom"-phase that the field of ophthalmology went through in the past decade or so. Right now there isn't really any inner ear therapies available to the mass market. Inner ear therapies fall broadly into two groups:
tinnitus elimination and
hearing loss recovery. [I recently did a market analysis tracking down financial stats, clinical trial data, and company information of all the major players in the otology market segment - I will attach it as a pdf file again below; there's some pretty helpful information in it...]
Since there aren't really any therapies available at the moment, what can a person do in such a situation - if faced with hearing loss and/or tinnitus? As I see it, there are two options:
1) Use non-standard treatment options within the field of regenerative medicine (LLLT and stem cells; possibly HIFU).
2) Get involved in clinical trials (the market overview I am providing below is very helpful in that respect - it contains everything you need to know - there is more going on than many people may realize).
Option #1
If a person decides to go for option #1, then there are some "problems" with that approach. The problems are that the therapy is unproven - meaning it may or may not work as intended, and there is also a financial aspect (stem cell treatments do not exactly come with a "money back guarantee" for the typical cost of about USD 25.000,-). To what extent regenerative therapies work is something I have discussed at great length in the following posts:

Reading through the posts - which contain my post therapy reflections on regenerative medicine - will enable a person to make a decision by/for themselves. I cannot make a decision for other people. Similarly, I cannot tell you about the success rate, because success rates are difficult to obtain reliably within the field of regenerative medicine. But the threads above contain at least some "hints" as to what a person can potentially expect from the various therapies.
The following link is also useful in that respect:

(Pages 6-9 in the pdf document above discusses stem cells in relation to hearing loss for people who have actually done it...! And it contains two audiogram done before/after for one of those pioneers, L Francis - see page 9).
I have also posted before/after audiograms in my introduction:

The following links are helpful in relation to finding stem cell treatment centres:
Stem Cells

Stem cell treatments use adult stem cells (not embryonic stem cells). Embryonic stem cells are only used for research. Hence there are no moral issues in getting a stem cell treatment.

Option #2
Getting involved in clinical trials is a chance to be amongst the first people in the world to receive a new treatment form or drug - and free of charge.
In approaching a clinical trial, a potential candidate should be aware of the following stages/phases:
Preclinical: drug is still in development phase (not ready for testing on human beings)
Phase I: safety evaluation of drug (on human beings) using sub-clinical dosages.
Phase II: efficacy evaluation of drug (on human beings) using various dosages (incl. placebo for double-blind studies).
Phase III: same as phase II, but using a larger group of patients in order to establish a more reliable estimate of the efficacy of the drug.
Phase IV + NDA follows thereafter...
Given the above, it is therefore not beneficial to enter a clinical trial before phase II has begun. But even better to wait for phase III (= less risk).
The draw-back with a clinical trial is that there is a "risk" of getting the placebo. And there is also a risk of developing unknown side-effects from the treatment. But it is free-of-charge (a big advantage to the price tag of the many thousands of dollars often involved in other self-chosen experimental therapies such as stem cells...)
For people who are interested in clinical trials in relation to tinnitus and hearing loss, the pdf document below is a good starting point for keeping track of what is going on at the moment. I would advise the "serious candidate" to contact the pharmaceutical companies directly (in order to learn more and keep yourself updated). But, only if you are serious about it - don't waste their time "for nothing" (these are often small companies with limited manpower; and often it is the CEO him- or her-self responding to e-mails and answering phone calls).

double-blind: neither the patient nor the doctor knows if the real drug or the placebo is being administered during treatment (this in order to guarantee objectivity of results).
Definition
NDA: New Drug Application.
A general note about hearing loss therapies currently being developed. The drugs being developed are typically aimed at patients with severe hearing loss. After treatment, candidates can expect to have their hearing threshold restored to about 20-25db (or just shy of stage I hearing loss). Hearing loss will
not be fully restored. Full restoration of hearing loss will not happen until many years from now (when some yet-to-be developed
embryonic stem cell therapy has been researched).
