Endoscopic-assisted Microsurgical Removal of Cerebellopontine Angle Lesions

Evaluation of Endoscopic-assisted Microsurgical Removal of Cerebellopontine Angle Lesions

It is a Prospective descriptive hospital based clinical study to determine the value of introduction of endoscope after microscopic excision of cerebello-pontine angle lesions to estimate the following :

1. Intraoperative judgement of lesions excision, residual parts, visualization and operative corridor pre and after endoscope introduction.
2. Post-operative tumor control confirmed comparison between pre and postoperative MRI.
3. Postoperative complications, advantages and disadvantages compared with these when use pure microscopic excision from the literature
