BACKGROUND The Le Fort I maxillary osteotomy approach for skull base tumor removal in the pediatric age group has not been widely discussed in the literature except for sporadic case reports and limited case series. OBJECTIVES To review our experience with the Le Fort I osteotomy and to propose that it be used as an alternative approach because of its many advantages for the removal of tumors...

BACKGROUND Carotid body tumors are rare tumors that arise from the paraganglionic cells of the carotid body. They are usually benign, requiring surgical resection as the treatment of choice. CASE REPORT We present a case of a 59-year-old man with a benign left carotid body tumor that progressed to a very large size, compromised the patient's airway, completely encased the carotid vessels, vagus...

Objective To investigate the expression of p16, cyclin D1, retinoblastoma tumor suppressor protein (Rb) and MIB-1 in skull base chordoma and chondrosarcoma tissues, and to determine the clinicopathological significance of the above indexes in these diseases. Methods A total of 100 skull base chordoma, 30 chondrosarcoma, and 20 normal cartilage tissue samples were analyzed by immunohistochemis...

Background: Skull base chordoma is a rare tumor with slow and progressive growth. Significance of this tumor is it’s difficult to access location in skull base. This is the reason for various proposed techniques for resection of the tumor. Endoscopic endonasal technique is a minimally invasive approach that gives surgeons opportunity of total resection of tumor and low morbidity. Total resectio...

AIM To visualize cranial nerves (CNs) using diffusion tensor imaging (DTI) with special parameters. This study also involved the evaluation of preoperative estimates and intraoperative confirmation of the relationship between nerves and tumor by verifying the accuracy of visualization. MATERIAL AND METHODS 3T magnetic resonance imaging scans including 3D-FSPGR, FIESTA, and DTI were used to co...

BACKGROUND AND PURPOSE Skull base chordoma has been widely studied in recent years, however, imaging characteristics of this tumor have not been well elaborated. The purpose of this study was to establish an MR imaging grading system for skull base chordoma. MATERIALS AND METHODS In this study, 156 patients with skull base chordomas were retrospectively assessed. Tumor-to-pons signal intensit...
