It’s true, some people with otosclerosis also have SNHL. Researchers now put otosclerosis in two categories, otosclerosis and cochlear otosclerosis. Some ENT’s feel that otosclerosis, or cochlear otosclerosis causes SNHL. They may be correct, however to date I have not personally reviewed anything that changes the treatment of people living with otosclerosis.
The vast majority of people living with otosclerosis will experience a conductive hearing loss at 250Hz, 500Hz and 1000Hz, making otosclerosis very easy to identify through a simple AC BC hearing test.
You mentioned cancer drugs. Cancer drugs may save a life, often making the risks of taking the drugs far less important to the patient than the benefits. Most cancer drugs are very ototoxic in nature, which simply means they cause hearing loss. (Many drugs are ototoxic in nature and it’s important that people properly research medications prior to starting a prescription). In the VERY limited studies of sodium fluoride, often combined with vitamin D and calcium, claims of success have been made, however those claims should be closely examined. How did the patients treatment options change? Did the patient still require hearing aids? Did the disease still progress? Was surgery still required?
I am of the opinion that otosclerosis has a clear path, one of progression. Whether one is of the belief that otosclerosis causes SNHL, as well as, conductive loss doesn’t change the treatment. While I am hopeful, and confident, in the future patients will have new options for treating otosclerosis, at present wearing hearing aids and/or having surgery are the only widely accepted treatments.
