Disease category
Sinusitis is a condition in which inflammation occurs in the sinuses, the air-filled spaces within the bones surrounding the nose, and it presents in acute, subacute, chronic, and recurrent forms.
Key mechanism
In addition to infections, colds, allergies, structural problems of the nose, and certain diseases can be associated with sinusitis.
Main causes/related factors
If the nasal mucosa swells or the sinus drainage pathways become blocked, mucus drainage and ventilation are impaired, which can lead to persistent inflammation and pressure.
Representative patterns
Typical symptoms include nasal congestion, facial pain or pressure, rhinorrhea, or post-nasal drip, which may be accompanied by cough, fever, and fatigue.
Individual differences
Allergic rhinitis, asthma, exposure to smoking or irritants, nasal polyps, or septal issues can influence an individual's onset and course of the disease.
Diagnosis
Acute sinusitis can begin after a cold; subacute lasts 4–12 weeks; chronic persists for more than 12 weeks; and recurrent occurs multiple times within one year.
Management
Diagnosis focuses on symptoms, medical history, and examination of the nose and face; endoscopy or imaging tests are considered if the course is prolonged or complications are suspected.
Treatment/Research Status
Viral colds and bacterial sinusitis cannot always be distinguished by symptoms alone, and the cause or severity should not be determined solely by mucosal changes seen on imaging.
Read Evidence
Management is carried out by reducing pain and nasal congestion and assisting in discharge drainage, while simultaneously addressing underlying factors such as allergies or structural issues, depending on the type and cause.
Key Precautions
Treatments may include saline nasal irrigation or sprays, steam/warm compresses, and analgesics, while antibiotics and decongestants are selected according to the situation.

At a Glance

Sinusitis is a condition in which inflammation occurs in the sinuses, the air-filled spaces within the bones surrounding the nose, and it presents in acute, subacute, chronic, and recurrent forms.

Typical symptoms include nasal congestion, facial pain or pressure, rhinorrhea, or post-nasal drip, which may be accompanied by cough, fever, and fatigue.

How the disease works

In addition to infections, colds, allergies, structural problems of the nose, and certain diseases can be associated with sinusitis.

If the nasal mucosa swells or the sinus drainage pathways become blocked, mucus drainage and ventilation are impaired, which can lead to persistent inflammation and pressure.

Variations in presentation among individuals

Allergic rhinitis, asthma, exposure to smoking or irritants, nasal polyps, or septal issues can influence an individual's onset and course of the disease.

The broad framework of diagnosis and management

Acute sinusitis can begin after a cold; subacute lasts 4–12 weeks; chronic persists for more than 12 weeks; and recurrent occurs multiple times within one year.

Diagnosis focuses on symptoms, medical history, and examination of the nose and face; endoscopy or imaging tests are considered if the course is prolonged or complications are suspected.

Current status of treatment

Viral colds and bacterial sinusitis cannot always be distinguished by symptoms alone, and the cause or severity should not be determined solely by mucosal changes seen on imaging.

Management is carried out by reducing pain and nasal congestion and assisting in discharge drainage, while simultaneously addressing underlying factors such as allergies or structural issues, depending on the type and cause.

Treatments may include saline nasal irrigation or sprays, steam/warm compresses, and analgesics, while antibiotics and decongestants are selected according to the situation.

How to read clinical trials

The packet records the FinESS Registry Study, a completed observational study related to sinusitis, but since results are not provided, it does not imply efficacy, causality, or standard of care.

Points to verify during clinical consultations

In clinical practice, it is important to verify symptom onset and duration, recurrence, warning signs such as fever, vision changes, or severe headache, allergies, asthma, current medications, and previous treatment responses.
