  Paranasal Sinus and Nasal Cavity Cancer Treatment - National Cancer Institute
Paranasal sinus and nasal cavity cancer is a disease in which malignant (cancer) cells form in the tissues of the paranasal sinuses and nasal cavity.
The nasal cavity lies above the bone that forms the roof of the mouth and curves down at the back to join the throat.
Paranasal sinus and nasal cavity cancers often have spread by the time they are diagnosed and are hard to cure.

  eMedicine - CT Scan, Nasal Cavity : Article by Charles Lee, MD
Understanding the anatomy of the nasal cavity and its anomalies is important because it leads to an understanding of imaging anatomy, which is needed to plan the surgical approach.
The nasal cavity is separated into halves by a midline, which is a partially bony and partially cartilaginous nasal septum that, unlike the lateral walls, is lined by squamous epithelium.
As the name implies, portions of the concha are aerated; this occurs either in the vertical portion that attaches to the cribriform plate or lateral nasal cavity walls or in the concha or curved (shell-like) portions of the concha.

The nasal septum divides the nasal cavity through the middle, and is formed by septal cartilage at the tip and by bone closer to the skull.
The nostrils lead to nasal cavities, one on each side, which in turn lead to the pharynx and then to the voice box (larynx) and windpipe (trachea).The nasal cavities are also connected to the paranasal sinuses and receive drainage of tear fluid through the nasolacrimal ducts; the  Eustachian  tubes connect  the  ears to the pharynx.
The bones surrounding the nasal cavities are the vomer and portions of the frontal, ethmoid, maxillary and sphenoid bones.

 The Nasal Cavity
The nasal mucosa is firmly bound to the periosteum and perichondrium of the supporting structures of the nose.
It is continuous with the adjoining cavities to which the nasal cavity communicates (e.g., the nasopharynx and paranasal sinuses).
This is a horizontal passage, inferolateral to the inferior nasal concha.

 ACS :: How Are Nasal Cavity and Paranasal Sinus Cancers Staged?
Nasal cavity and paranasal sinus cancers are staged using a system that is agreed upon by the American Joint Committee on Cancer (AJCC).The AJCC/TNM System describes the extent of the primary Tumor (T), the absence or presence of metastasis to nearby lymph Nodes (N), and the absence or presence of distant Metastasis (M).
The tumor is limited to the nasal cavity or the ethmoid sinus, although it may have invaded the bones of these sites.
For all patients with nasal cavity or paranasal sinus cancer, the relative 5-year survival is 54%.

 ACS :: What Are Nasal Cavity and Paranasal Sinus Cancers?
This cavity runs along the top of the palate (the roof of the mouth, the shelf that separates your nose from your mouth) and turns downward to join the passage from the mouth to the throat.
The nasal cavity opens into a network of paired sinuses: maxillary sinuses are in the cheek area, below the eyes, and on either side of the nose.
These cancers usually occur on the roof of the nasal cavity and involve a structure called the cribriform plate, which is a bone deep in the skull, between the eyes, and above the ethmoid sinuses.

Cancer of the paranasal sinus and nasal cavity is a disease in which malignant (cancerous) cells are found in the tissues of the paranasal sinuses or nasal cavity.
The nasal cavity is the passageway just behind the nose through which air passes on the way to the throat during breathing.
Five-year survival rates for people with nasal cavity and sinus cancer range from 11 percent for people with advanced cancers to almost 100 percent for people with very small cancers that have not spread and are found and treated early.

 Paranasal sinus and nasal cavity cancer
Cancer of the paranasal sinus and nasal cavity is a disease in which cancer (malignant) cells are found in the tissues of the paranasal sinuses or nasal cavity.
Because the paranasal sinuses and nasal cavity help in talking and breathing, and are close to the face, patients may need special help adjusting to the side effects of the cancer and its treatment.
Treatment of cancer of the paranasal sinus and nasal cavity depends on where the cancer is, the stage of the disease, and the patient's age and overall health.

 Nasal Cancer Symptoms : Nose Cancer Symptoms
Cancers of the nose may develop either in the skin covering the nose or in the lining of the nose itself or in the passage way at the back of the nose, called the nasopharynx, which joins the nose to the throat.
Nasal cancer symptoms appear in the local area and eventually in distant areas as it spreads.
Early nasal cavity cancer can produce symptoms that are very similar to less serious nasal diseases such as swelling of the sinuses, headache, chronic infections, and/or blurred vision.

 Fact Sheet: Deviated Septum
The shape of your nasal cavity could be the cause of chronic sinusitis.
The nasal septum is the wall dividing the nasal cavity into halves; it is composed of a central supporting skeleton covered on each side by mucous membrane.
The ideal nasal septum is exactly midline, separating the left and right sides of the nose into passageways of equal size.

 Lab Manual - Ear & Nasal Cavity
Since the cavity develops as an outpocketing of the nasopharynx, it is lined by a mucosa which forms the inner layer of the tympanic membrane (the outer layer is skin); the mucosa also covers the two nerves, two tendons and three bones that are the principal contents of the cavity.
The tympanic cavity retains its pharyngeal connection as the auditory (eustachian) tube which, if not blocked, assures atmospheric pressure on both sides of the tympanic membrane; unfortunately, it also is a route for infection to reach the middle ear (otitis media) and even pass beyond it to the mastoid air cells.
Remove the lateral wall of the nasal cavity on one side of the head and explore the maxillary sinus and the ethmoidal air cells.

 Narial Nasal Cups - Jala Neti Pot - Allergy & Sinus
Sometimes the membranes in your nasal passages are dry and cracked due to central heating, climate or the use of some medications, particularly those designed to treat congestion.
Many find that keeping the nasal passages clear of allergens and pollutants is enough to control their allergies and to reduce the incidence of colds, flu and bronchitis.
We recommend the plastic version of the Narial Nasal CupĀ® neti pot for children because it is unbreakable and the spout is slightly smaller and may be a more comfortable fit for a child's nostrils.

 Latest Nasopharynx Cancer Treatments
Since the nasal cavity is so close to the maxillary, ethmoid and sphenoid sinuses, these structures are called the “paranasal sinuses”;, and disease of the nasal cavity can spread to them and vice versa.
However, disease starting in the paranasal sinuses tends to be of different types, and is classified separately from nasal cavity diseases.
Nasal cavity disease can also spread into the eye sockets by penetrating the thin bone of the “orbit” (eye socket) surrounding each eye.

 Juvenile Angiofibroma
Juvenile angiofibroma is a rare vascular mass that usually develops in the backmost part of the nasal cavity, often but not exclusively, in adolescent males.
On physical examination, a mass is seen in the back of the nasal cavity, usually arising in the area between the back end of the inferior turbinate and in front of the eustachian tube.
Since serious bleeding from the back part of the nasal cavity rarely occurs in young people, if it happens, particularly in an adolescent male, this tumor must be given first and foremost consideration.

 Information about Expert Head and Neck Cancer Diagnosis and Treatment at Continuum Cancer Centers of New York
The nasal cavity and adjacent sinuses are located above the roof of the mouth (hard palate) and border the eyes and the brain at the level of the skull base.
Tumors affecting the nasal cavity and sinuses may show up as symptoms normally related to adjacent structures.
People with a history of chronic sinus infections (especially with nasal polyps) and wood dust exposure seem to be at a higher risk of developing these tumors.
