Preservation of facial and acoustic nerves in the total removal of large and small acoustic tumors

Report of two cases

Restricted access

✓ Two cases are presented in which an acoustic tumor was totally removed without the aid of an operating microscope. In one of them, a large lesion was excised, with restoration of the patient's hearing postoperatively. The anatomical problems are analyzed, and the relevant literature is reviewed briefly.
