The evaluation of venous drainage patterns prior to surgery for skull base meningioma is important owing to their deep location and the vulnerability of surrounding vascular structures. In recent years, the microsurgical skull base approach has matured as a surgical technique, making it an important option for reducing complications related to skull base meningioma surgery. In addition, knowled...

Background: The last decades have witnessed remarkable progress in the field of endoscopic skull base surgery. The nose has become an established route for addressing different skull base lesions. The reconstruction after resection is a critical step for optimum surgical outcome. Objective: Evaluation of the difference in the clinical outcomes between the use of vascularized flaps and free graf...

BACKGROUND Some problems have been found in the usually adopted combined approach for the removal of intra-extracranial tumors in skull base. Herein, we described a pure endoscopic transnasal or transoral approach (ETA) for the removal of intra-extracranial tumors in various skull base regions. METHODS Retrospectively, clinical data, major surgical complications, pre- and postoperative images...

Bone metastasis is the most frequent type of distant metastasis in nasopharyngeal carcinoma (NPC). In this study, we investigated the correlation between the skull base bone destruction and the distant bone metastasis in patients with NPC. A total of 449 cases with NPC who were diagnosed and had definitive radiotherapy from 2001 to 2006 were enrolled in this study. The skull base bone destructi...

BACKGROUND AND PURPOSE The developing fetal skull base has previously been studied via dissection and low-resolution CT. Most of the central skull base develops from endochondral ossification through an intermediary chondrocranium. We traced the development of the normal fetal skull base by using plain radiography, MR imaging, and CT. METHODS Twenty-nine formalin-fixed fetal specimens ranging...

BACKGROUND AND PURPOSE Skull base osteomyelitis typically arises as a complication of ear infection in older diabetic patients, involves the temporal bone, and has Pseudomonas aeruginosa as the usual pathogen. Atypical skull base osteomyelitis arising from the sphenoid or occipital bones without associated external otitis occurs much less frequently and initially may have headache as the only s...

forty-nine preserved specimens (31 male and 18 female) of trachylepis aurata transcaucsasica were examined with respect to metric and meristic features and dry skull anatomy to assess sexual dimorphism. thirty-one morphological characters and 36 anatomical characters in dry skulls were examined. subdigital lamellae under the forth toe, neck length, neck length/snout vent length, and six skull c...

BACKGROUND Our aim was to grade MRI-detected skull-base invasion in nasopharyngeal carcinoma and evaluate the prognostic value of the grading. METHODS The MRI scans and medical records of 924 patients with histologically diagnosed nondisseminated nasopharyngeal carcinoma were reviewed retrospectively. RESULTS MRI-detected skull-base invasion was not found to be an independent prognostic fac...

BACKGROUND AND PURPOSE Interpretation of CT of the anterior skull base in children depends on knowledge of the pattern and chronology of ossification. The purpose of this study was to ascertain the age at which the anterior cranial fossa is fully ossified as assessed on CT examinations. MATERIALS AND METHODS This was a retrospective review of 127 CT examinations of children ranging from 1 day...

OBJECTIVES/HYPOTHESIS To provide a description of the techniques and limitations of nasoseptal flap takedown and reuse during second-stage and revision endoscopic skull base surgery and review the institutional experience with the use of this reconstructive technique. STUDY DESIGN : Case series. METHODS A retrospective analysis of cerebrospinal fluid (CSF) leak outcomes was performed for a ...
