Brainstem evoked response audiometry (BERA or ABR) involves sophisticated, computerized equipment. Sounds are placed in the ear, and the brainstem's response is recorded from electrodes (similar to electrocardiogram electrodes) that are taped to the patient's head. This testing is extremely helpful in:
- Distinguishing sensory (inner ear) from neural (nerve) causes of hearing loss
- Helping to localize problems in the brainstem auditory pathway
- Determining the ability to hear soft sounds, in selected cases
The term "acoustic" is a misnomer, as the tumor rarely arises from the acoustic (or cochlear) division of the vestibulocochlear nerve. The term "neuroma" is also a misnomer, since it means "nerve tumor" but an acoustic neuroma is a Schwannoma. The correct medical term isvestibular schwannoma, because it involves the vestibular portion of the 8th cranial nerve and it arises from Schwann cells, which are responsible for the myelin sheath in the peripheral nervous system.
In laymens terms, acoustic neuroma is a benign slow growing brain tumor. Yes I said it, scary word Brain tumor. You can only imagine the shock and terror I experienced when I was told this. The statistics have been set at 1 in 100,000 having such a tumor, but with the increased use of mri to detect tumors it has been found they are much more prevalent and often go undetected for years. Most do not show major symptoms until the age of 30.
So where do we go from here. Well first things first I will go in for a MRI on the 5th of November and we will go from there. If it is acoustic neuroma the treatment varies based on the tumor. Small ones are monitored yearly via MRI, while larger ones have to be removed to eliminate risk of complications. The acoustic neuroma is the only known medical issue to cause these symptoms, if it is found that is not the cause, then it remains a mystery and only the symptoms can be treated. In either case I will need to use a form hearing aid in my left ear.
So that is where things stand as of now. I am doing ok. Though I ask that everyone keeps me in their prayers. As anyone can imagine being told you may have a brian tumor, is a traumatic experience to say the least. I am terrified, but hopeful with god at my side I will come through ok. I hope and pray that it is not a tumor. But at the same time I know that I am in a country with wonderful healthcare and I will get the best treatment possible. So before we press the panic button lets take a step back, and realize it is just a possibility, a scary one all be it, but not definitive.
I love you and I miss you
