Previous Surgery and Outcome

Meningioma Previous Surgery Outcome

Previous surgery:  To see whether or not a history of prior surgery had any influence on outcome following meningioma surgery, “Previous surgery (Yes)” group was compared to those with no prior surgery with respect to outcome (GOS) (based on a review of 800 operative cases, personal series).  A total of 93 patients had previous operation(s).

The incidence of “Good” outcome (GOS 4 & 5) patients goes down significantly from the “No surgery” group to the “Prior (Yes) surgery” group.

In brain surgery, prior operation causes scar tissue formation at the site of surgery, making exposure and identification of the tumor and the surrounding “normal” anatomic structures difficult and, at times, dangerous, adding to overall surgical risks.  Patients with a history of previous surgery do less well following surgery.
