Etiology.
1, nasal-derived infection (expansion of nasal infection)
Acute rhinitis: one of the common causes of sinusitis, especially acute sinusitis.
(1) especially prone to complicate acute septal sinusitis. The mucosa is continuous with each other to facilitate the invasion of inflammation into the sinuses.
(2) other diseases of the nasal cavity: such as nasal septal deviation, turbinate hypertrophy, mucosal hypertrophy, tumors and foreign bodies in the nasal cavity, and nasal metaplasia, etc., can block the sinus opening, so that the sinus ventilation and drainage is blocked and inflammation.
(3) pollutants through the nasal cavity into the sinuses: such as swimming, diving, diving improper methods, so that the sewage into the sinuses and inflammation.
(2) Proximity to tissue-derived infections: such as facial dermatitis, facial bone osteomyelitis, dental disease.
3, blood-borne infection: acute infectious diseases such as influenza, pneumonia, measles.
4, trauma-derived infections.
(1) trauma: maxillary and frontal sinus trauma is common, such as fracture, foreign body, blood clot, infection, etc. cause acute lesions of the sinuses.
(2) air pressure injury: sinusitis caused by sudden changes in air pressure, more often seen in the frontal sinus and maxillary sinus.
5. Other
(1) systemic factors: such as excessive physical fatigue, cold, moisture, malnutrition and other resistance decline.
(2) poisoning: toxic sinusitis can occur when iodine poisoning.
Clinical manifestations.
1, systemic symptoms: chills, fever, loss of appetite, constipation and other symptoms of toxin poisoning, children may be accompanied by vomiting, diarrhea, cough, etc.
2, local symptoms: ① nasal obstruction ② more pus ③ headache
Diagnosis.
1.Local redness, swelling and pressure pain.
2.Nasal cavity examination with acute congestion and swelling, with large amount of purulent discharge.
3.Unilateral nasal discharge is foul-smelling, and rhinogenic maxillary sinusitis should be considered.
4. Imaging of the sinuses.
Treatment.
1, systemic treatment.
2.Local drug control.
