Abstract:
Acute and chronic rhinosinusitis (ARS and CRS) are common conditions with a significant impact on health-related quality of life and disease-related costs. ARS is predominantly of viral aetiology and self-limiting, while bacterial ARS is rare and overdiagnosed. CRS is a persistent inflammatory disease, categorised histopathologically by type of inflammation, with therapeutic strategies varying by severity and endotype. Recent advancements have improved outcomes for patients with severe CRS. This review finds that future research aims to refine biomarkers and personalise treatment for even more favorable outcomes.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
