How develops the acoustic neuroma? What are the symptoms and when to do tests.
His Elefth.Ferekydi, Professor, University / University of Athens
The acoustic neuroma is a benign tumor that is generated by the stato- auditory nerve. It is deeper than the inner ear at the base of the skull.
It grows very slowly. Initially the symptoms are mild. The patient reports tinnitus. But there is hearing loss that initially is not perceived because it affects the high frequencies, that is not the speech frequencies.
For this reason, we should in any case have embolisms be akoografima.
As the tumor grows aggravating the hearing and added balance disorders and dizziness. Even when the tumor grows too appears to paralysis facial nerve, that twisted face.
In excessive increase in tumor size affect various cerebral nerves causing difficulty in swallowing and finally pressed brainstem and cause instability and muscle weakness (paresis) limb. In the final stages appear hydrocephalus and symptoms of increased intracranial pressure, ie headache, nausea, vomiting, drowsiness and coma.
The diagnosis made by the discovery of the tumor with CT and MRI. But we suspect the volume when the patient says unilateral tinnitus and balance disorders and our akoografima reveal drop of high frequencies.
Then we will ask for MRI which, if there is a tumor will help us to discover in the early stages, ie when the volume is still very small.
For the treatment of neuroma earpiece have been proposed various methods of treatment. So far it has not given a definitive solution to what is the most appropriate treatment. This is because the safest and most effective treatment can provide a definitive solution without potential complications has not been found. Due to the location of acoustic neuroma and how its development is unfortunately not possible. Generally there are various methods of treatment such as conservative monitoring, surgical removal, stereostatiki radiosurgery even classical radiotherapy. Each of these has advantages and disadvantages.
Depending on the size, location of the tumor, the age and the patient’s preference, the specialist otolaryngologist in cooperation with the neurosurgeon, decide upon the patient response method but having in mind to maintain the quality of the patient’s life.
