What is Frontal Sinusitis?
Frontal sinusitis is a pathological condition of the paranasal sinuses in which there is inflammation of the frontal sinus that prevents drainage of the mucosa properly and produces symptoms.
The common cold is the most common cause of frontal sinusitis. The best way to treat frontal sinusitis is by nasal decongestants. Upon reaching the anatomy of the frontal sinuses, it is a pair of air-filled cavities immediately behind the eyes.
The frontal sinus along with three other breasts produces mucus that drains through the nasal passage. When there is an excess of mucus formed, inflammation occurs that does not allow proper drainage of the mucosa that causes nasal congestion and what we call frontal sinusitis.
What causes frontal sinusitis?
The main cause of Frontal Sinusitis is the excessive accumulation of mucus in the frontal sinus as a result of breast inflammation. There are several factors that can cause this accumulation of mucus in the sinuses. These factors are:
Frontal sinusitis caused by viral infection:
The common cold or the most prevalent virus in the winter season, causing colds and coughs, are the most common cause of accumulation of mucus in the frontal sinus that results in frontal sinusitis. When an individual has a cold or the flu, the amount of mucus produced by the sinuses increases significantly and, as a result, the sinuses become clogged.
Bacterial infection that causes frontal sinusitis:
This is another cause of frontal sinusitis. The nasosinusal cavity is full of what we call cilia, which are small strands of hair. Its function is to prevent the entry of any foreign residue into the paranasal sinuses, but these hair filaments are not always effective and sometimes the bacteria infiltrate through these cilia and enter the paranasal sinuses.
It is easier for bacteria to enter the paranasal sinuses immediately after a viral infection, since there is a rich accumulation of mucus in the paranasal sinuses and provides a breeding ground for bacteria. The symptoms of Frontal Sinusitis as a result of a bacterial infection are the most serious.
Frontal sinusitis caused by nasal polyps:
Polyps are abnormal growths that can occur anywhere in the body and the frontal sinus is no exception. A polyp in the frontal sinus tends to block the passage of free air to and from the breast, resulting in the accumulation of mucus and frontal sinusitis.
Deviated nasal septum that causes frontal sinusitis: under normal conditions, the nasal septum in an individual is straight, but in some individuals it deviates. People who have this condition cannot breathe through their nose properly. This, in turn, results in the lack of free passage of air to and from the sinuses for frontal sinusitis.
Symptoms of Frontal Sinusitis
The most common symptom of frontal sinusitis is intense facial pain located around the eyes and forehead. Facial pain around the eyes or forehead. Some of the other symptoms of Frontal Sinusitis are:
- Persistent nasal discharge
- Sensation of pressure behind the eyes
- Difficulty sniffing objects
- Persistent cough that gets worse at night
- General feeling of being sick
- Fever of low grade, but in children with Frontal Sinusitis the fever is unusually high
- Persistent lethargy
- Sore throat.
How is frontal sinusitis diagnosed?
In order to diagnose frontal sinusitis, a detailed history of the patient will be taken regarding the duration of symptoms in order to differentiate between a common cold and frontal sinusitis. The doctor can feel the frontal sinuses looking for areas of pain and tenderness. If frontal sinusitis is suspected, the patient will be referred to an otolaryngologist who will more thoroughly control the nasal cavity to look for conditions such as nasal polyps.
A certain amount of mucosa can also be collected for analysis to rule out any type of infection. In addition, a nasal endoscopy can be performed to look at the inside of the frontal sinus to see if there is an excessive accumulation of mucus. An advanced image in the form of MRI or a CT scan of the frontal sinus can also be done to look for any other cause of the symptoms. Finally, a blood test will be performed to verify other possible causes of the symptoms. The results of all these tests will confirm the diagnosis of frontal sinusitis.
