Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever. [6] [7] Sinusitis is a condition that affects both children and adults.
In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom. This is due to pain originating from the frontal sinus, it being above the brow bones. Less common is pain referred to the temporal, occipital, or retrobulbar region. Epistaxis or serosanguineous secretion from the nose may occur.
The functional unity of the two mucosa speaks in favor of this replacement. A distinction is made between acute and chronic rhinosinusitis. Acute sinusitis lasts a maximum of 12 weeks. The clinical symptoms of acute rhinosinusitis are purulent nasal secretion, nasal obstruction and/or tension headache or feeling of fullness in the facial area ...

Inflammation is a normal part of the human immune response, whereby leukocytes (white blood cells), including neutrophils (white blood cells that specialize in causing inflammation), gather, and chemokines (proteins released from certain cells, which activate or elicit a response from other cells) accumulate at any location in the body where ...
The frontal sinuses are located in the frontal bone; the sphenoidal sinuses in the sphenoid bone; the maxillary sinuses in the maxilla; and the ethmoidal sinuses in the ethmoid bone. [2] [13] A narrow opening called a sinus ostium from each of the paranasal sinuses allows drainage into the nasal cavity. The maxillary sinus is the largest of the ...
Paranasal sinuses: 1. frontal sinuses, 2. ethmoid sinuses (ethmoidal air cells), 3. sphenoid sinuses, 4. maxillary sinuses The exact cause of nasal polyps is unclear. [ 1 ] They are, however, commonly associated with conditions that cause long term inflammation of the sinuses. [ 8 ]
The lower respiratory tract consists of the trachea (windpipe), bronchial tubes, bronchioles, and the lungs. [6] Lower respiratory tract infections (LRIs) are generally more severe than upper respiratory infections. LRIs are the leading cause of death among all infectious diseases. [7] The two most common LRIs are bronchitis and pneumonia. [8]
