Esthesioneuroblastoma and Carcinomas of the Nasal Cavity

Sinonasal malignancies are rare, pathologically diverse, and biologically unpredictable tumors. They tend to have minimal or nonspecific symptoms that mimic benign (inflammatory) disease until there is invasion of adjacent structures. Most patients present with advanced disease. Computed tomography and magnetic resonance imaging are complimentary studies but magnetic resonance imaging optimally defines the tumor’s extent and dictates the need for neurosurgical attention. Advanced endoscopic techniques allow for the resection of some well-selected tumors as part of a multimodal treatment plan. The intimate relationships with the orbit and brain make surgical management challenging. Optimal patient outcomes can only be achieved with carefully constructed, multidisciplinary, multimodal management paradigms.
