There are theories about antivirals, carbogen therapy, vitamins, etc. but it's all hit or miss--they usually don't even know what causes a sudden hearing loss.
If the infection was a presumed viral inner-ear infection, antibiotics won't help. If they think he had a middle-ear infection that moved into his inner ear (which I'm not even sure can happen--not an expert here, though), that would probably be different treatment.
I hope he recovers his hearing. Hearing loss in one ear is not fun but you can live with it if you have to. I did for 9 years. I just got a Baha (bone-anchored hearing aid) and that is a great help, I love it.
