Acute sinusitis is acute suppurative sinusitis. The incidence of maxillary sinus is the highest, followed by ethmoid sinus and frontal sinus, and sphenoid sinus is the least.

Etiology:

1, secondary cold, usually a lot of bacteria in the nasal cavity, but not sick. Only when the body is tired, catches a cold, and the resistance drops, bacteria will take the opportunity to multiply in large numbers, causing acute inflammation of the nasal mucosa. The mucosa of sinus and nasal cavity is connected with each other. So acute rhinitis spreads. Can cause sinusitis.

2. Infection and spread of adjacent lesions. If root abscess occurs, it can pierce the bottom wall of maxillary sinus and cause maxillary sinusitis, which is called "odontogenic maxillary sinusitis". Tonsillitis and chronic inflammation of pharyngeal lymph tissue sometimes cause sinusitis.

3. Direct factors. For example, after swimming, sewage directly enters the sinuses through the nasal cavity. Or trauma leads to direct bacterial invasion, infection and inflammation.

4. Systematic factors. Such as fatigue, malnutrition, excessive smoking and drinking, etc., especially for patients with chronic diseases such as diabetes, tuberculosis and chronic nephritis. The whole body has poor resistance and is prone to sinusitis. The severity and manifestations of symptoms vary. Such as fear of cold and fever, general weakness, listlessness, loss of appetite, etc. The child has severe symptoms, such as high fever, convulsion, vomiting and cough. Nasal congestion, pus or headache.

It should be pointed out that isolated sinusitis is rare and sometimes accompanied by other sinuses, both of which are called sinusitis or paranasal sinusitis. In order to better understand the characteristics of various types of sinusitis, they are listed separately (you can also click to watch other types of sinusitis: maxillary sinusitis, ethmoid sinusitis and frontal sinusitis).

The sphenoid sinus is located in the sphenoid bone, one on the left and the other on the right, both of which lead to the sphenoid recess through the hole in its anterior wall.

Acute sphenoid sinusitis rarely occurs alone. Headache often occurs in the top of the head and occipital region, and can be reflected to the neck and behind the eyeball.

Chronic sphenoid sinusitis is rare, and ethmoid sinusitis often occurs simultaneously. If chronic suppurative sinusitis has spread to sphenoid sinus, most of them have already formed total sinusitis. Its clinical manifestations are similar to chronic ethmoiditis and maxillary sinusitis, and X-ray can confirm the existence of sphenoid sinusitis. After mastering the characteristics of sinusitis, it can be distinguished from chronic rhinitis, and usually both exist at the same time.

Chronic:

1 General treatment includes furosemide nasal drops, antibiotics and maxillary sinus puncture and irrigation.

2, if the general treatment effect is not good. Detailed nasal examination under nasal endoscope or CT examination of paranasal sinuses should be carried out, mainly to understand whether there are any lesions that affect paranasal drainage. The left CT film shows bilateral maxillary sinus inflammation with effusion.

3, surgical treatment, including surgical removal of the cause, (such as nasal septum high deflection for nasal septum correction; For hypertrophic or polypoid middle turbinate, partial middle turbinectomy is feasible. If there is nasal polyp, nasal polypectomy and radical maxillary sinus surgery are performed.

4. At present, the popular surgical method is functional endoscopic sinus surgery. This method has little surgical trauma, accords with normal physiological anatomy and has good effect. If possible, try this operation.

Acute: The treatment of acute frontal sinusitis is mainly antibiotics and nasal drops.
