What are the causes of odontogenic sinusitis?

Sinusitis is an inflammation of one or more sinuses and is relatively common clinically. There are many types of sinusitis, mainly acute and chronic. Odontogenic sinusitis is also a type of sinusitis. When it comes to odontogenic sinusitis, there are many main factors that cause the disease.

1. Reduced overall body resistance, such as excessive fatigue, cold and dampness, malnutrition, vitamin deficiency, and poor living environment.

2. Allergic constitution, systemic diseases such as anemia, insufficient blood endocrine function (such as thyroid, pituitary and gonadal function), acute infectious diseases such as influenza, measles, scarlet fever, diphtheria, etc. can all induce the occurrence of this disease.

3. Some nasal diseases, such as deviated nasal septum, hypertrophy of the middle turbinate, nasal polyps, allergic rhinitis, nasal foreign bodies or nasal tumors, can also cause sinusitis.

4. Adjacent lesions, such as tonsillitis or adenoid hypertrophy, infection of the roots of the maxillary second bicuspids and the first and second molars, damage to the maxillary sinus wall during tooth extraction, or caries roots falling into the maxillary sinus can also lead to sinusitis.

5. Others, such as sinus trauma and fracture; improper diving posture when swimming (such as standing diving), or improper nose blowing after diving and swimming, sewage entering the sinus; nasal packing left in the nasal cavity for too long; rapid descent during high-altitude flight, the sinus cavity and the outside world form a relative negative pressure, and nasal secretions are sucked into the sinus, etc. can also cause the disease. Clinical manifestations: severe nasal congestion, inability to smell fragrance or odor, yellow and turbid nasal discharge or blood, fishy smell, nasal reflux, foreign body sensation in the throat, severe head swelling, usually forehead, occipital, or bilateral temple pain, most severe at noon and afternoon. The nasal fascia is red and swollen, especially in the middle turbinate, middle nasal meatus and olfactory fissure in the upper part of the nasal cavity. There is tenderness in the forehead or face. X-rays can first show thickening of the sinus mucosa, poor light transmittance, and even turbidity. Sometimes fluid levels can be seen in the room, and pus in the sinus. Dry mouth, loss of appetite, mental depression, insomnia and forgetfulness, palpitations, constipation, etc.
