In spite of the early recognition and treatment of these tumors, catastrophes still occur as a direct result of surgical intervention. These unfortunate results may be an aftermath of surgical attack on even the smaller tumors.

The purpose of this discussion is to report some of the difficulties which we have experienced in operating on patients with acoustic tumors. We will demonstrate the relationship of these difficulties to disturbances of the cardiorespiratory centers in the brain. It is our opinion that many of the problems encountered during the surgical removal of these tumors, as well as much of the morbidity and mortality following surgery, are due to a compromise of
