Anatomic Considerations for Sinonasal and Ventral Skull Base Malignancy
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…
Evaluation of Patients with Sinonasal and Ventral Skull Base Malignancies
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…
Overview of Sinonasal and Ventral Skull Base Malignancy Management
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…
