Endoscopy of the cerebellopontine angle.
The authors present their experience of 191 patients from June 1990 to December 1993 with endoscopy of the cerbellopontine angle using a limited retrosigmoid approach. The advantages of endoscopy of the cerebellopontine angle are the simplicity and efficiency of the procedure, and less invasive surgery. The authors emphasize the importance of the endoscopic procedure: first in acoustic neuroma surgery to get more accurate information about the relationship between the tumour and the adjacent structures, and to control the lateral end of the internal auditory canal; second in hemifacial spasm or facial neuralgia surgery, intraoperative endoscopy is the key point giving a sure and safe way to recognize the offending vessels.
