What are the paranasal sinuses? The four pair of sinuses are often described as a unit and termed the paranasal sinuses. Functions of the sinuses include humidifying and warming inspired air, insulation of surrounding structures (eyes, nerves), increasing voice resonance, and as buffers against facial trauma.

Anatomy of the Sinuses Anatomy of the Sinuses. Anatomy of the Sinuses. The bones of the face and skull near the nose contain four pairs of air-filled pockets, which are called the paranasal sinuses. Each sinus has an opening, called an ostium, which connects it to the nose.

- The sinuses are air filled cavities located in the face and around the nose. The sinuses are named according to the bone in which they are located. There are four paired sinus cavities. The maxillary sinuses are located in each cheek bone.

Endoscopic sinus surgery The purpose of FESS is to restore normal drainage of the sinuses. Normal function of the sinuses requires ventilation through the ostia (mouth-like opening) and is facilitated by a mucociliary transport process that maintains a constant flow of mucus out of the sinuses. All sinuses need ventilation to prevent infection and inflammation, a condition known as sinusitis.

PARANASAL SINUSES ANATOMY PARANASAL SINUSES ANATOMY. 1  Air cavities, which in the nasal cavity are paired, between certain bones in the skull are known as paranasal sinuses. The bones which surround these sinuses and create the cavity are also responsible for the naming of the particular sinus.

The Nasal Cavity The posterior ethmoidal sinuses open out at the level of the superior meatus. The only structure not to empty out onto the lateral walls of the nasal cavity is the sphenoid sinus. It drains onto the posterior roof. In addition to the paranasal sinuses, other structures open into the nasal cavity. The nasolacrimal duct acts to drain tears from the eye – it opens into the inferior meatus. The auditory (or eustachian) tube opens into the nasopharynx at the level of the inferior meatus.

- INTRODUCTION. The paranasal sinuses (“the sinuses”) are air-filled cavities located within the bones of the face and around the nasal cavity and eyes. Each sinus is named for the bone in which it is located:Physiology. Frontal-one sinus per side, located within the bone of the forehead above the level of the eyes and nasal bridge (figures 1 and 3). 2  Sphenoid-one sinus per side, located behind the ethmoid sinuses; the sphenoid is not seen in a head-on view but is better appreciated looking at a side view (figure 3).

- Paranasal sinuses are filled with air Their function is to-humidify and warm the inspired air,provide resonance to voice,lighten the skull bones, andact as thermal insulators… to protect orbit and cranium from variation in temperature of air in our nose Paranasal sinuses are air containing cavities (hollow spaces) in certain bones of skull.

- Sinusitis is an inflammation of the membranes lining the paranasal sinuses—small air-filled spaces located within the skull or bones of the head surrounding the nose. Sinusitis can be caused by an infection or other health problem, and symptoms include facial pain and nasal discharge.

Section 11: Respiratory System The respiratory system is composed of conducting and respiratory passages, which serve several functions. The primary function of this system is the exchange of oxygen and carbon dioxide; secondary functions are phonation and olfaction. The conducting portion of the respiratory system includes the nasal cavity, paranasal sinuses, nasopharynx, larynx, trachea, and bronchi. The conducting portion, from the nostrils to the lungs, warms, humidifies, and filters the air.

- Physiology. The pink membranes lining the sinuses make mucus that is cleared out of the sinus cavities and drains into the nasal passage. The right and left nasal passages are separated in the middle by a vertical plate of cartilage and bone called the nasal septum (figures 1 and 2).

What are the paranasal sinuses? A sinus is a hollow, air-filled cavity in the skull that is connected to the nasal airway by a narrow hole in the bone (ostium). Normally all are open to the nasal airway through an ostium. Humans have four pair of these cavities each referred to as the: frontal sinus (in forehead)

- The most common type of paranasal sinus and nasal cavity cancer is squamous cell carcinoma. This type of cancer forms in the squamous cells (thin, flat cells) lining the inside of the paranasal sinuses and the nasal cavity.

Picture of the Sinuses The sinuses are a connected system of hollow cavities in the skull. The largest sinus cavities are around an inch across; others are much smaller. The sinus cavities include: • The maxillary sinuses (the largest), in the cheekbones. • The frontal sinuses, in the low-center of the forehead. • The ethmoid sinuses, between the eyes, at the nasal bridge. • The sphenoid sinuses, in bones behind the nasal cavity.

WHAT ARE SINUSES? WHAT ARE SINUSES? Sinuses are air pockets that are located within the bones of the skull and face and are connected to your nasal passages by small tubes or channels, the osteomeatal complex. These channels permit air to flow from the nose into the sinuses and allow drainage of mucous from each sinus into the nose.

Picture of the Sinuses Normally, the sinuses are empty except for a thin layer of mucus. The inside of the nose has ridges called turbinates. Normally these structures help humidify and filter air. The nose is divided in the center by a thin wall, called the septum.

- Sinus disease, often referred to as paranasal sinus disease, is a debilitating condition which can affect everyone of us.Sinus disease is undoubtedly one of the most uncomfortable ailments you can experience without being termed seriously ill.n many cases, chronic sinus disease can be treated with antibiotics and nasal sprays as prescribed by the doctor or, in milder cases, via over the counter or homeopathic remedies. As quite a lot is know about sinusitis today, there are plenty of options available for you.

- The sphenoid sinus is the most posterior paranasal sinus. It is found superior to the nasopharynx, just anterior and inferior to the sella turcica and posterior to the posterior ethmoid cells. The sphenoid ostium can be seen medial to the superior turbinate and posterior to the basal lamella.

Nose, Sinuses and Smell Nose, Sinuses and Smell. The nose is commonly known as the organ that produces the sense of smell, yet it is the structures deep to the nose in the nasal cavity that produce this important sense. Using the complex olfactory system of the nasal cavity, humans can differentiate at least 5,000 to 10,000 different scents. Flanking the nasal cavity are the infamous sinuses, which produce pain and discomfort when inflamed. Yet, in spite of their infamy, the sinuses provide several important functions to the head....

What Are Nasal Cavity and Paranasal Sinus Cancers? The nasal cavity. The nose opens into the nasal passageway, or cavity. This cavity is a space that runs along the top of the roof of the mouth (the palate, which separates your nose from your mouth) and then turns downward to join the passage from the mouth to the throat.he nasal cavity and the paranasal sinuses are lined by a layer of mucus-producing tissue called mucosa. The mucosa has many types of cells, including: 1  Squamous epithelial cells, which are flat cells that line the sinuses and make up most of the mucosa.
