Combined transcranial and endoscopic endonasal approaches remain useful in the treatment of ventral skull base malignancies. The extended bifrontal transbasal approach provides wide access to the anterior ventral skull base…
Key points • The surgical approach should be sufficiently wide to allow the limits of dissection to be visualized and accessed easily with a 0° endoscope and straight instruments. •…
Surgical management of clival lesions presents numerous therapeutic challenges because of the close proximity of surrounding critical structures. With a detailed understanding of the endoscopic endonasal approach and relevant considerations,…
Key points • A transfacial or craniofacial approach allows for wide, potentially en bloc resection and is ideal for tumors that involve surrounding soft tissue, the palate, anterolateral frontal sinus,…
Key points • Ventral skull base tumors are rare head and neck tumors that present with nonspecific symptoms. • The principles of endoscopic skull base surgery involve extensive surgical planning…
Tremendous pathologic diversity among sinonasal and ventral skull base malignancies complicates development of a uniform and prognostically relevant staging system. Because of the comparatively low incidence of these tumors, comprehensive…
Key points • Sinonasal malignancy is rare in general but with an understanding of anatomy from an endonasal perspective many of these lesions may be dealt with using a totally…
A wide variety of tumors present in the sinonasal and ventral skull base. Patients often have nonspecific symptoms initially and present with advanced tumors, affecting the orbit and other adjacent…
Key points • Due to the close proximity of critical structures, initial evaluation should include assessment of visual complaints (eg, diplopia) and extraocular movements, unilateral middle ear effusion suggesting Eustachian…
