Can a traumatic hearing loss be repaired?

Much depends on how much of the loss is conductive (structural) and how much is due to nerve involvement. Most of the time when loss is due to an explosion, there are elements of both.

Microsurgery of the ear is very successful most of the time, as it corrects structural anomalies.

The audiologist who is following him should be able to give you information about how much of each kind of loss he has, and whether or not aural rehabilitation (done by a speech pathologist) will likely be necessary.

Realize that even with moderate nerve loss, he will get along just fine. He may even be a candidate for amplification (hearing aids) depending upon just how successful the surgery is.

Aural rehab is not "speech" therapy in the traditional sense. Rather, it teaches a patient how to make the best out of their residual hearing.

I have permanent hearing loss from inner ear surgery many years ago. What I was not informed about was the effect of inner ear surgery on balance etc, and the surgeon and hospital were very flippant about the chance of losing all hearing in that ear.

It sounds to me like you need to prepare with your boyfriend a list of questions prior to meeting the surgeon. Preparation is a must when you are in front of a surgeon in an intimidating environment and with a small window of time.

Ask - what the surgeon will be doing - explicitly. As a layman I suspect this may be repair to the ear drums and potentially the small bones that transmit the vibration. (And therefore nor inner ear).

Ask - what result is the surgeon looking for. What is the recovery period. What is the best and worst case scenario. I agree with the former comment re: speech therapy.

All the best. I very much doubt whether he will get 100% hearing again (as a layman this is pretty cheeky of me), however I operate reasonably well with one fully functioning ear. He may still be limited in crowd situations.

Once again - all the best - you need more information!

If he is having a surgery then they must believe they will have some result.

I have some hearing loss and I was told it can never be recovered. I doubt he will need much speech therapy since he was a hearing individual all his life

Good Luck
