Asian people frequently show small noses, narrow nasal apertures, and congestive mucosa on the turbinates and septum. To reduce the risk of nasal morbidity with increased radicality for skull base tumors in these patients, we developed endoscopic transnasal interseptal approach (ETISA) in transsphenoidal surgery for invasive clival tumors (ICTs). Indication for ETISA is radical resection for tu...

We report herein a case of lower clival chondroid chordoma, focusing on the surgical procedure of endoscopic endonasal surgery. A 36-year-old woman presented with progressive headache, right shoulder pain, and right hypoglossal nerve palsy. Computed tomography (CT) and magnetic resonance (MR) imaging revealed an extradural tumor located in the lower clivus, including the anterior aspect of the ...

Sir, The clivus is one of the common sites for diverse pathological lesions. 1 Tuberculosis commonly involves the craniovertebral junction causing atlanto-axial dislocation. However, primary skull base tuberculoma is extremely rare. A case of primary spheno-clival tuberculoma without involvement of the craniovertebral junction is reported and the management is discussed. A 24-year-old, non-immu...

Chondroid chordoma commonly presents as clival osseous and extradural mass. A 15-year-old boy presented with progressive visual deficit, headaches and diplopia since three years. Computed tomography (CT scan) showed a skull base tumour, but was wrongly reported at the time as chronic sphenoidal sinusitis and nasal polyps. In the past three months, he developed dysphagia, urinary retention and c...
