Paranasal sinus and nasal cavity cancer is a type of cancer that is caused by the appearance and spread of malignant cells into the paranasal sinus and nasal cavity. The cancer most commonly occurs in people between 50 and 70 years old, and occurs twice as often in males as in females. [ 3 ]
Several types of cancer are associated with high survival rates, including breast, prostate, testicular and colon cancer. Brain and pancreatic cancers have much lower median survival rates which have not improved as dramatically over the last forty years. [4] Indeed, pancreatic cancer has one of the worst survival rates of all cancers.
Extranodal NK/T-cell lymphoma, nasal type (ENKTCL-NT) (also termed angiocentric lymphoma, nasal-type NK lymphoma, NK/T-cell lymphoma, polymorphic/malignant midline reticulosis, [3] and lethal midline granuloma [4]) is a rare type of lymphoma that commonly involves midline areas of the nasal cavity, oral cavity, and/or pharynx [5] At these sites, the disease often takes the form of massive ...
The fleshy external end of the nasal septum is called the columella or columella nasi, and is made up of cartilage and soft tissue. [2] The nasal septum contains bone and hyaline cartilage. [3] It is normally about 2 mm thick. [4] The nasal septum is composed of four structures: Maxillary bone (the crest) Perpendicular plate of ethmoid bone
Won (2000) found evidence of a VNO in 13 of his 22 cadavers (59.1%) and 22 of his 78 living patients (28.2%). [41] In a study using retrospective analysis of nearly one thousand outpatient nasal endoscopies, Stoyanov et al. (2016) found the organ to be present in 26.83% of the Bulgarian population. [42]
The mucous membrane is thickest, and most vascular, over the nasal conchae. It is also thick over the nasal septum where increased numbers of goblet cells produce a greater amount of nasal mucus. It is very thin in the meatuses on the floor of the nasal cavities, and in the various sinuses. It is one of the most commonly infected tissues in ...
Most of the nasal cavity and paranasal sinuses is lined with respiratory epithelium as nasal mucosa. In the roof of each cavity is an area of specialised olfactory epithelium. This region is about 5 cm 2 (0.78 sq in), covering the superior concha, the cribriform plate, and the nasal septum. [24]
The paranasal sinuses are joined to the nasal cavity via small orifices called ostia. These become blocked easily by allergic inflammation, or by swelling in the nasal lining that occurs with a cold. If this happens, normal drainage of mucus within the sinuses is disrupted, and sinusitis may occur. Because the maxillary posterior teeth are ...
