Yes, chemicals can cause permanent ear ringing (tinnitus). The chemicals which are best studied include aminoglycosides (a type of antibiotic, such as gentamycin). Not only do these chemicals cause tinnitus, but also deafness. There are many other medications which can cause tinnitus, which is often dose related. In addition there are countless chemicals which can cause tinnitus upon exposure. Most of these chemicals come with an MSDS sheet to explain the risks of exposure.

Otomax can cause temporary deafness in dogs, but only in the ear it was placed in, unless it was used in both ears. It is really really super rare though. Usually the deafness clears up in about 6 weeks, and the medication should be switched, maybe to Surolan. The other possibility is that the infection the dog was put on the otomax for did unforseen damage to the ear that just happened to show up when you started treating it.
Conductive deafness is when the sound waves are prevented from reaching the inner ear. It can be because of wax in the outer canal, fluid inside it, or the tiny bones in the ear have seized up. With perceptive deafness, sound waves can reach the inner ear, though it is a disease of the nerves leading to the brain or a condition affecting the function of the inner ear. Most cases of deafness fall into the category of conductive and perceptive deafness, though other cases of deafness are as simple as the result of old age.
