✦ Synopsis

Abstract

Since 1949, only 52 cases of hemangiopericytoma (HPC) of the nos eand paranasal sinuses have been reported in the literature. Of the latter, only 2 originated from the maxillary sinus. This article reports 2 new cases. One arose in the maxillary sinus and involved the pterygopalatine fossa, skull base, and infratemporal fossa. The second tumor was located in the sphenoethmoidal recess. A new combination of techniques for resection of hemangiopericytoma of the skull base is described. Prognostic criteria for such tumors are reviewed, in conjunction with histological diagnosis.

Benign osteoblastoma is an uncommon fibroosseous neoplasm with a predilection for the vertebrae and long bones, and a 2-to-1 male-tofemale ratio of occurrence. Peak incidence occurs in the second decade, with 80% of all patients being under 30 years of age. The clinical, radiographic, and histologic

Background. Cavernous sinus involvement represents the most difficult problem in en bloc resection of malignant skull base tumors. We developed three types of surgical procedures for manipulating the cavernous sinus to achieve en bloc resection of these tumors. Methods. In a type 1 procedure, the c
