Hearing Loss Associated with Schwannomas of the Ears

Complications associated with hearing can lead to life altering changes. For many adults, the complications with hearing loss may be attributed to the development of tumors within and around the ears that, with proper treatment, can be resolved quite easily.

As a tumor that grows quite slowly, Schwannoma development from abnormal growth of the Schwann cells around the nerves of the auditory canal. When not caught early, the Schwann cells continue to grow, slowly, resulting in blockage of the auditory canal which ultimately leads to hearing loss.

If you are experiencing complications with hearing loss, it is necessary that you seek medical attention to determine if there is a complication involving the Schwannoma. With MRI of the brain, your physician can properly assess the complication as Schwannoma tumors can not be seen with the naked eye in many cases. Often situated around the tympanic membrane, the MRI can provide not only the exact location, but also the size and impact on the surrounding facial nerves.

Once narrowed in size and location, your physician will want to schedule an outpatient excisional biopsy to remove the tumor. In many cases, the tumor will be sent for evaluation to rule out any complications involving malignancy. If benign, you can expect no further treatment will be required and, in most cases, you should experience a full restoration of your hearing.

Because Schwannoma have a high rate of recurrence, regular hearing evaluations may be necessary to ensure there is not a repeat development of tumor growth in the auditory canal. When any sign of hearing deficit is present, your physician may want to repeat the MRI study to determine if additional Schwannoma have developed. If there is evidence of development, additional excisional biopsy should be performed.
