For those of you who have tinnitus, like myself, from head injury the answer likely rests in that the cochlea of our inner ear has been damaged.
Notch dips on audiograms tend to show hearing loss at certain frequencies. Even if normal hearing is recorded an a standard audiogram the pitch of your tinnitus can be found on a distortion product otoacoustic test. I thought i would post those who are trying to figure on the reason for head injury induced Tinnitus. What i find incredibly unusual is posters on this board who claim Tinnitus has vanished after more than 6 months. Spontaneous recovery of hair cell damage usually does not go further than a recovery rate of 6 months and according to most if not all medical research inner and outer ear hair cells do not regrow. |

My tinnitus never went away completely, but I do recall it being stronger during my PCS in 2012. It has returned in full force since I bonked my head in early December.

Recovered by the end of February. A branch fell on my hardhat at work on 10/7. Not sure if completely concussed but have been feeling "out of it". Definitely injured my upper cervical region and upper back. Out of work for the time being. |

martin82,
From what I have read, they can not directly connect tinnitus to hair cells, at least not for everyone. There are many of us whose tinnitus comes and goes without any understandable cause. Mine will spike after a glass of water or eating something. It can become pulsatile tinnitus for no reason. I found I can find the pitch of my tinnitus with a piano keyboard. Mine is at about 1108 hz or C#6 or slightly higher. I think a better subject title could have been, "Tinnitus Almost Everyone" LOL It is a very common complaint.

I like your title Mark..lol.. Tinnitus ALMOST everyone
Mark out of curiosity i'm wondering if you had a hearing test? In particular otoacoustic emissions to measure hair cell damage? My belief is that the shock waves from the impact damage these hair cells similar to the way a blast would. The concussive wave knocks out certain hair cells that control certain frequencies. As we age we all gradually lose ear hair cells as we age. The problem is that we might lose a few hundred every year however with a concussion we can instantly lose several thousand. As certain frequencies are instantly lost the brain cannot interpret the sounds and thus we are left with squealing, hissing or buzzing. I would be of the opinion that 99% of post concussion patients with Tinnitus have some form of damage to the cochlea/ auditory nerve cells. |

I have had a hearing test. I showed good hearing except a 10% loss in the high frequencies. Nothing out of the norm for my age.
My most recent concussion was extremely mild but it caused an increase in my tinnitus. Since, my tinnitus has increased with no further trauma. The fact that eating or drinking something can cause a spike makes me think it has something to do with blood chemistry. What do you mean by 'Did you habituate again ?' ?

Hi Mark!
Interesting about the blood chemistry. I never thought about that nor have most doctors. Habituate is a term used by TRT specialists as a way for people to learn to ignore there Tinnitus. I'm in the same boat as you Mark. I have 10% hearing loss in the high frequencies which is normal. However when i took a DPOAE (Distortion Product Otoacoustic Emissions Test) the case was clear. The blow to the right side of my head destroyed the hair cells in the 1500-2000 htz range. The left side perfect however the right side certainly impacted. If you ever take an otoacoustic emissions test it'll tell you the exact frequency of your tinnitus and where the damage occurred. Quote:

It might go away for some within the first week, less probable after a few months.
Did you have an audio test? Did you habituate again? |
