Rhinosinusitis is a relatively common disorder relating to inflammation of the sinuses and nasal passageways. Most cases are acute, lasting only a few weeks. Chronic cases occur less frequently with symptoms persisting three months or longer.
Symptoms:
- Rhinorrhea (runny nose)
- Vasomotor rhinitis: intermittent episodes of rhinorrhea, sneezing and congestion
- Post-nasal drainage
- Facial pressure
Causes & Types
Allergic Rhinitis
Allergic rhinosinusitis is a group of symptoms leading to inflammation in the nasal cavity when breathing in allergens such as dust, pollen, mold or pet dander.
Allergies may be seasonal due to pollen or grass and worsen during the springtime. Animal and mold allergies typically occur indoors and may be exacerbated from heating systems or old air filters.
Nonallergic Rhinitis
Nonallergic rhinitis is a group of symptoms similar to nasal allergies that occur for reasons unrelated to the immune system. Symptoms include wheezing, coughing, sneezing and congestion with no apparent immune-related cause.
It may occur due to certain odors or irritants, sudden changes in weather or responses to medications.
Nasal Airway Obstruction
A deviated septum, nasal polyps and anatomical abnormalities may obstruct the nasal airways and limit proper airflow. Blocked nasal airways can lead to mucus buildup and irritation.
Neurogenic Rhinitis
The nasal nerves are responsible for regulating nasal and sinus health, telling the sinuses when to swell and secrete mucus. Off-balance nasal nerves cause the sinuses to think they need an inflammatory response when it is unnecessary.
This condition can lead to congestion and other rhinitis symptoms to occur without cause.
