MRI diagnosis and differential diagnosis of the cerebellopontine angle tumors;

We reported 25 cases of cerebellopontine angle (CPA) tumor operation with Ho:YAG laser assistance during the operative procedure.

Objective To evaluate the operative approach of transpetrosal postlabyrinthine presigmoid to cerebellopontine angle.

The anatomic and adjoining structures of the cerebellopontine angle(CPA) are so complexed and important that they have large clinic and practical value to know better anatomic realationship in the area and to identify and protect the nerves and blood vessels during operation.
