Paranasal Sinuses Research Paper
Paranasal Sinuses:
They are four paired air-filled spaces located within bones of the skull and face, composed of maxillary, frontal, and sphenoid sinuses and the ethmoid air cells. They have various functions such as lightening the weight of the head, humidifying and heating inhaled air, increasing resonance of speech, protecting vital structures. Some sinuses diseases have the same symptoms as odontogenic diseases, and vice versa, odontogenic diseases have the same symptoms as sinuses diseases, and may affect sinuses.
Maxillary Sinus:
It’s the largest of all paranasal sinuses, it lies in the maxillae inferior to the eyes and has a pyramidal shape. It’s the first sinus filled with fluid after birth. The first phase occurs during 0-3 years …show more content…
These inflammatory changes may lead to ciliary dysfunction and retention of sinus secretion.
10% of sinusitis causes are of dental infections such as, periapical infection from teeth, trauma, and dental material in antrum, implants, periodontitis, oroantral fistula, or infected dental cyst.
Clinical features:
Acute maxillary sinusitis is most common sinusitis and often due to cold, with nasal discharge or pharyngeal drainage. Few days later, discharges increase and the patient may start complaining of pain and tenderness to pressure or swelling. The patient may sense the pain in his teeth (molars, premolars), and may be sensitive to percussion. In this case, teeth may seem the cause of infection, but key signs of these symptoms are: fever, chills, malaise, and elevated leukocyte counts.
Chronic Maxillary sinusitis is a sequel of 3 months acute infection that failed to heal. External signs appear only during acute exacerbations when increased pain and discomfort are apparent. It’s often associated with pneumatization of the middle concha that inhibit mucus outflow, with anatomic derangements including deviation of nasal septum, allergic rhinitis, asthma, cystic fibrosis, and dental infections.
