Hello,

46yo male here working in Melbourne AU, recently diagnosed last month with IAC small 6x4x4 mm AN on my left ear.  Had gradual hearing loss over the last 10 years but Jan 2018 felt 50% hearing loss and tinnitus, hence discovered this little bugger.

Went to Neurologist this week and put me on WW for 6 months then MRI on March 2019.

No balance issues just severe hearing loss and mild tinnitus on AN ear. Have issue on identifying where the sound coming from. My colleague on my left side calling my name but I looked on my right side :)

Are you guys doing anything else while on wait and watch? I want to preserve my remaining hearing on left if possible. Just in case my AN grow I leaning towards GK treatment.

I've been on watch and wait for close to five years with no change in hearing status yet.

I haven't been doing this all along, but for the last nine months or so I've been taking 81mg aspirin.

There is some research suggestive that aspirin may inhibit growth.

I figure while I'm waiting why not give it a try.

I don't think aspirin will save hearing though. There's nothing in the research about that.

I was told radiation would or could rapidly degrade hearing but that may have been advice specific to my case.

Surgery can cause sudden total loss of one-sided hearing so that's a risk too.

In general I'm happy with how I'm feeling so I wouldn't risk that for hearing alone.

After reading so many posts there doesn't seem to be much consistency regarding hearing loss, tumor size, etc. Some people have large tumors with no hearing loss and others have small tumors with a lot of hearing loss so it's hard to advise.

Good luck

Cityview I hope the aspirin do wonders for many and stop the growth of AN. I will ask my specialist about it.
Are you doing scan every year?

Do you know if AN shrinks itself later in life?

For me it's an anxious first 6 month wait.

I can appreciate the anxiety surrounding the diagnosis and feeling like it's hard to wait the 6 months. I've had a lot of stress and anxiety about the diagnosis as well. In general I don't have anxiety but just dealing with the diagnosis and figuring out what, if anything, to do about it. So I sympathize. Some positive things to think about: the tumor may be exactly the same size in six months or it may grow only slightly. One bit of advice, I wouldn't panic if the next scan shows it to be a little bigger. Sometimes when they interpret the scans over years, the sizes can go up and down because of the way that MRIs work.  The imaging is done in "slices" so that can make it difficult to measure, especially smaller tumors.

I do get yearly scans. In some cases I have had more than one per year. I think the first few scans after diagnosis are spaced about six months apart to determine the rate of growth. As I was told, they had no way to know, at the beginning, if the tumor had grown in two months or many years.

I have no information about whether or not they shrink when people get older.

Here is some information about the aspirin regimen. It is not proven yet, but they have found some preliminary, promising evidence so now they are officially doing research.

Good Luck with everything and take care.

That's excellent advise, Cityview. I'll keep those in mind. I'm gaining lots of relevant information on this forum.

Almost 3 years ago I went for a MRI scan for my hearing lossand there was no AN found that time. .

My ENT told me that AN will reach a peak size and then it will plateau, which research had shown that as well. but then again every AN is different.

My wait and watch has just started now I have to find out when is the best time to have intervention, or just keep continue observation.

I saw one recent webinar here in forum that if you have dizzy spells could be an indication of a growing tumour. I had this 3 years ago and thankfully no more after that.

Almost 8 years W & W with only 3mm AN in IAC. But Im weird. No real hearing loss, massive balance and dizziness issues, fatigue and brain fog. I just developed double vision over the past couple years too, so there may be something else going on, but MRI looked OK. I also have ear pain and fullness. Go figure!
3mm diagnosed December 2010 when I was 45. Very unusual presentation - severe vertigo, then dizziness daily, now just occasional dizziness, but it can be debilitating some days. No hearing loss! But yes to ear fullness and wonky brain. Watch and wait.

I think I saw that webinar if it was the Vanderbilt one. I found it interesting the the doctor said that small tumors and those that aren't causing vertigo/dizziness are less likely to grow.
Figuring out exactly how long to be on observation and when and if to have treatment is so variable. My main focus has been about figuring out the hearing preservation part of it – radiation vs. surgery vs. observation.
I keep coming back to the fact that it's very small and I have my hearing so it's hard to treat it now.
There's a lot to consider so I just go with what seems the safest overall.

Good luck to you and I hope things remain stable for you.

In regard to the aspirin regiment, here is the link to the clinical trial which has started and is recruiting:

https://clinicaltrials.gov/ct2/show/NCT03079999.

However, the ability of aspirin to prevent AN growth was only seen in one study and other groups have tried and failed to confirm this result. Below is the result of a recently published paper that found no correlation:

Aspirin does not prevent growth of vestibular schwannomas: A case-control study.
MacKeith S1, Wasson J1, Baker C1, Guilfoyle M2, John D1, Donnelly N1, Mannion R2, Jefferies S3, Axon P1, Tysome JR1.

Abstract
OBJECTIVES/HYPOTHESIS:
To determine if aspirin intake is associated with reduced growth of vestibular schwannomas (VS). To determine the prevalence of contraindications to regular aspirin in patients with VS.

STUDY DESIGN:
Retrospective, observational case-control study.

METHODS:
The study utilized a postal questionnaire and telephone interviews to determine aspirin exposure. Propensity score matching was used to control for age, sex, and tumor size. Cases were defined as patients with VS proven to have grown on serial magnetic resonance imaging (MRI). Controls were defined as patient with VS stable on serial MRI. Prevalence of regular aspirin use was compared in patients with growing VS versus stable VS. Absolute and relative contraindications to aspirin intake were recorded.

RESULTS:
Six hundred fifty-three patients with VS were contacted, and responses were received by 67% (220 cases and 217 controls). The mean tumor size was 11.3 mm (9.0 mm and 13.3 mm in controls and cases, respectively). Aspirin exposure was more common in stable VS than growing VS (22.1% vs. 17.3%). However, following matching to control for covariates, aspirin was not found to be associated with VS stability (P = .475). Multiple logistic regression (analysis of variance) found tumor size to be the only factor strongly associated with tumor growth (P < .0001). Ninety-two percent of patients were able to take aspirin, with the majority being at low risk of complications from regular use.

CONCLUSIONS:
This study aimed to examine the relationship between aspirin intake and VS stability. In contrast to previous reports, after controlling for covariates, the findings do not demonstrate an association. Only tumor size at diagnosis appears predictive of risk of VS growth.

So while taking a daily aspirin may be beneficial to the heart, I don't believe it will prove to be of much help in controlling AN growth.

Hello, how are you all? wishing you and your family a Happy New Year 2019!! More prosperity and a shrinking AN's :)

i noticed since last week when I stand up from bed I feel dizzy for about 3 sec, same thing when I lie down to bed feels dizzy for about 3 sec. I tried Dr Google and points me to Benign paroxysmal positional vertigo. Is this normal on people with AN's?

Could this be sign that my ANdroid is growing? Sometimes its uncomfortable or maybe I am just stressed. I hope it will go away soon...

I wouldn't automatically assume that new symptoms mean that it has grown, but you could mention it to your doctor and see what he/she says.

There have been occasions when I thought I had a symptom, asked for an early MRI, and nothing had changed.

However, the first six months of diagnosis, are important ones for determining growth etc.

It can be hard if it's causing excessive worry.

Some people will have treatment just because of that and they don't prefer to wait.

I can appreciate all points of view about it.

Hope you feel better.

I know what you mean about BPV.  I have had it for several years. When I go to the dentist, I cannot tolerate them lowering my head too far down. I can't sleep flat, I have to have my head elevated. One day I was doing floor exercises at the gym with a trainer, and got so dizzy I had to stop. I assume it was from changing my positions so much. Yoga is out of the question, I wouldn't last 10 minutes. One day I got very dizzy in the supermarket, and had to sit in my car for several minutes until it passed. On some occasions, when I get up out of a chair and walk into another room rather quickly, I will have a transient vertigo attack and have to grab onto something until it passes. Usually the attacks are only momentary, but some have lasted a minute or two. I have learned to keep Dramamine with me at all times when I am away from home.  I have also found that I get dizzy when walking for extended periods of time (i.e. 30-60 minutes). I will feel somewhat dizzy while walking and it gets even worse when I stop moving.  You are certainly not alone in regard to the dizzies and I do believe that the AN either causes the dizziness or exacerbates it.

I have a relative who has Ménière's disease and I understand how it's difficult to live with inner ear symptoms. This can be very debilitating at times.

My small AN is in my IAC. I’d like to know how many others have AN’s which are located in the lateral aspect of their IAC as I do. I’ve been told it’s location will continue to negatively impact my hearing no matter treatment I opt for.

my small AN is located in lateral portion of IAC as well.  latest MRI showed it had grown through/obliterated the fundal cap and has now grown an extension into the cochlea.  ENT doc says i'm not a good candidate for surgery because the canal is dry, having lost it's normal fluid environment, making extraction without damaging facial nerve very unlikely.  already lost useful hearing in that ear, have very poor balance, shrill tinnitus, also pulsatile tinnitus, and hyperacusis.  but so far only minimal symptoms of facial nerve impairment.  doctor says i wouldn't recover hearing, and would most likely add to my woes if they tried the translab surgery.  so i'm on permanent watch and wait, providing it doesn't start growing in the other direction (medially).

*April15/2019:  i had an appt today with a new doctor regarding the AN.  He explained the fundal cap issue in a different way.  i had misunderstood it.  So for the benefit of anyone who comes across this post, I am adding the following:  The fundal cap is not a structure per se, it is a "space" that is ordinarily filled with fluid.  When the AN grew out the lateral end of the IAC, and grew into the cochlear aqueduct, it displaced the fluid.  Therefore, there is less chance of saving my hearing and/or removing the tumor without damage to facial nerve.  He said it's just easier to work with in there if there is a fluid-filled space surrounding the tumor.

So sorry for your diagnosis and symptoms.  Even small ANs when confined to the IAC seem to cause big problems.  It sounds like you have had more than 1 MRI. How long has it been since you were first diagnosed with AN?  I sincerely hope you will have no facial nerve issues.
