Surgical results of 158 petroclival meningiomas with special focus on standard craniotomies.

ABSTRACT:

Objective

The goal of this retrospective study is the evaluation of risk factors for postoperative neurological deficits after petroclival meningioma (PCM) surgery with special focus on standard craniotomies.

Materials and methods

One-hundred-fifty-eight patients were included in the study, of which 133 patients suffered from primary and 25 from recurrent PCM. All patients were operated on and evaluated concerning age, tumor size, histology, pre- and postoperative cranial nerve (CN) deficits, morbidity, mortality, and surgical complications. Tumor-specific features-e.g., consistency, surface, arachnoid cleavage, and location-were set in a four-grade classification system that was used to evaluate the risk of CN deficits and tumor resectability.
