Certain symptoms are linked with these tympanicum tumors. People that have these tumors may experience loss of hearing, how much, depends upon the size. If the tumor is small enough, they will probably not experience any hearing loss at all. Now, a larger tumor may also cause ringing of the ear, known as "pulsatile tinnitis." Pulsatile tinnitis is caused because the tumor has become large enough to push against the ear ossicles, creating a vibration in the ear, a ringing sensation. Now on the other hand, some may be small enough to not cause any symptoms at all.
In a case of a glomus tumor, the only sure way they would diagnose a glomus tympanicum 
tumor would be to do an MRI, MR angiography, or CT, in which it would appear as a red dot or a mass located posterior to the eardrum. These exams will also tell the size of the tumor as well, which is important in case it is pushing against the jugular vein or possibly the brain. In this case the surgeon would want to know the situation for possible treatments.

In this case the surgeon would want to know the situation for possible treatments. There are a few different options for treatment. One possible treatment, depending on the location and size may be to remove it by laser. This would be the best for the patient. The second treatment would be to surgically remove it; this is will be for the larger, more complicated tumors. Lastly, radiation treatment. While this doesn't erradicate it, for older individuals it may be a good option because it will be able to stop the growth, while not compromising themselves during a surgery.
