| Summary: | Aim:Treatment options for acoustic neuroma
are; microsurgery, stereotactic radiotherapy and the use of these two options
together. In this study, after treatment quality of life and changes in the
tumor size,hearing level of patientswhom were applied stereotactic radiotherapy
due to acoustic neuroma in our clinic were evaluated..Material and Methods: In our clinic,
between September 2009 and May 2016 22 patients who had acoustic neuroma
smaller than 3 centimeter were evaluated retrospectively. The patients
underwent stereotactic radiotherapy with a dose of 12 Gray. Size was measured
before and after treatment with magnetic resonance and hearing level and speech
discriminations were calculated with audiogram.Their quality of life was
evaluated with SF-36 Quality of Life Assessment Scale after treatment.Results: In both of these patients groups with
acoustic neuroma whose tumor is located at only internal auditory canal or at
cerebellopontine angle and internal auditory canal; it was showed that
stereotactic radiotherapy can cause hearing loss and decrease in speech
discrimination scores but this difference is not statistically significant
(P>0.05). In recent follow-up magnetic resonance imaging was taken and in 12
of these patients; sizes of the acoustic neuroma was stabil and on the other
hand in 2 of the patients there was a progression and in 8 of the patients
there was a regression. In the evaluation of Quality of Life Assessment Scale;
most decrease was found in vitality scores.
Conclusion: Stereotactic radiotherapy can be used with hearing
function, changes of tumor size and low morbidity in quality of life in
patients with diagnosis of acoustic neuroma under 3 centimeter.
