What is frontal sinusitis?

Frontal sinusitis is essentially a type of rhinitis. It has many causes, the most common of which is infectious diseases. Another cause is a decline in one's physical condition, which leads to frontal sinusitis. Frontal sinusitis is very serious. During the illness, it can cause headaches, dizziness, and occasionally a runny nose, which affects sleep quality. You can gently massage both sides of the nose with your hands to relieve the symptoms, or you can go to the hospital to remove polyps in the nose. Let me give you some specific information.

Causes

1. Sinus infection

The sinus openings are relatively small. Once narrowing or obstruction occurs, the ventilation and drainage of the sinus cavity will be affected and it will be easy to accumulate pus or develop into chronic inflammation. Moreover, the sinus openings and sinus walls are close to each other, so inflammation of one sinus can easily affect the adjacent sinuses.

2. Nasal infection

(1) Acute rhinitis: It is a common cause of sinusitis, probably because the continuity of the mucous membranes of the two facilitates the invasion of inflammation into the sinuses.

(2) Other nasal diseases: deviated nasal septum, hypertrophic nasal conchae, thickened mucosa, tumors and foreign bodies in the nasal cavity, and nasal allergies can all block the sinus openings, causing obstruction of sinus ventilation and drainage and inflammation.

(3) Pollutants enter the sinuses through the nasal cavity: improper swimming, diving, or snorkeling techniques, or blowing one’s nose forcefully after swimming, can cause sewage to enter the sinuses and cause inflammation. This type of infection is mostly caused by anaerobic bacteria, and the clinical symptoms are generally severe.

(4) The nasal packing is left in the nasal cavity for too long; local irritation and contamination, as well as obstruction of ventilation and drainage of the sinus opening lead to inflammation.

3. Adjacent tissue infection

4. Blood-borne infection

5. Traumatic infection

Trauma such as fractures, foreign body retention and blood clot infection; barotrauma is caused by sudden changes in air pressure, and is more common in the frontal and maxillary sinuses.

6. Systemic factors

Such as reduced immune function, diabetes, malnutrition, vitamin deficiency, etc.

1. Systemic symptoms

Symptoms may include loss of appetite, irritability, chills and fever, constipation, insomnia, and mental depression.

2. Local symptoms

(1) Nasal symptoms: Persistent nasal congestion on the affected side may be caused by swelling of the nasal mucosa or accumulation of nasal secretions in the nasal cavity; Runny nose: Nasal secretions are mucopurulent or purulent, more in the morning, and often related to head drainage; Decreased sense of smell.

(2) Frontal purulent fistula If there is frontal bone osteomyelitis, a frontal purulent fistula may form, mostly located on the anterior wall and bottom of the frontal sinus.

(3) Headache: If the drainage of the frontal sinus is blocked, headache may occur, and there may be reflex headache in the distribution area of ​​the trigeminal nerve. The symptoms of frontal sinusitis headache start as a full headache, which then gradually becomes localized to the upper inner corner of the eye socket and the forehead on the affected side. The pain has an obvious time pattern, occurring every morning after waking up, gradually getting worse, being worst at noon, gradually easing in the afternoon, and disappearing in the evening, only to recur the next day. There is obvious tenderness when touching the upper inner corner of the orbit.
