Nasal Cavity and Paranasal Sinuses

Part of the Frozen Section Library book series (FROZEN, volume 5)


Included in this chapter are nasal cavities, frontal sinus, ethmoid complex, sphenoid sinus, and maxillary sinuses. These cavities and sinuses are lined by Schneiderian mucosa, consisting of pseudostratified columnar ciliated epithelium with interspersed goblet cells. The roof of the nasal cavity is the cribriform plate, specific location for olfactory neuroblastoma. The sinonasal Schneiderian (inverted type) papilloma appears to be a precursor of a sinonasal squamous cell carcinoma. Because of the intimate anatomic relationship with the brain, some intracranial lesions/tissues can be seen and the details will be discussed in Chapter 6.
