      A 47 year old lady from Kolkata was evaluated for decreased hearing in the left ear. MRI revealed an acoustic schwannoma. BERA (audiometry) revealed profound to severe hearing loss on the left side. She came for radiosurgery. She was irradiated with cyberknife radiosurgery technique in January 2013. Six months later she came for follow up. Her hearing had improved and it was confirmed with an Audiometry then. MRI also showed a decrease in the size of the lesion.

Acoustic schwannoma is a benign neoplasm in the eight cranial nerve.  Surgery for these lesions are complicated by the fact that preservation of hearing is a difficulty. Cyberknife radiosurgery delivers adequate dose to control the tumor growth with preservation of hearing.

We have successfully completed more than 1000 cases 

The patient was under treatment with Dr.Rathna Devi, senior consultant Radiation Oncologist.
