Clinical Causes: Allergic reactions to pollen, dust mites, mold, or pet dander Chronic exposure to irritants like smoke, pollution, or strong odors Structural abnormalities in the nasal passages History of frequent respiratory infections Genetic factors influencing immune response Atrophic changes in the nasal mucosa due to aging or other conditions Chronic granulomatous diseases such as tuberculosis or granulomatosis

Key Symptoms: Persistent nasal congestion or obstruction Runny nose with clear, purulent, or thickened nasal discharge Frequent sneezing episodes Post-nasal drip and throat irritation Reduced or loss of sense of smell Nasal crusting, dryness, or ulceration (particularly in atrophic or ulcerative forms) Facial pain or pressure, especially around the sinuses Bleeding from the nose in some types, such as ulcerative rhinitis

Diagnosis Path: Nasal examination by a healthcare professional is essential for diagnosing chronic rhinitis. This may include visual inspection of the nasal passages, endoscopy, and imaging studies like CT scans. In some cases, tissue sampling or biopsy may be necessary to determine specific types, especially if granulomatous or ulcerative features are suspected. Identifying underlying causes through allergy testing or blood work may also aid in accurate diagnosis.

Treatment Protocols: Treatment approaches vary depending on the specific type and underlying causes of chronic rhinitis. Common options include: - Saline nasal sprays or irrigations to keep nasal passages moist - Medications such as antihistamines, nasal corticosteroids, or decongestants - Antibiotics if bacterial infection is present (particularly in purulent rhinitis) - Managing allergies through immunotherapy or allergy medications - Surgical interventions in cases of structural abnormalities or to remove nasal polyps - Addressing environmental irritants by reducing exposure - Specific therapies for atrophic or ulcerative rhinitis may involve specialized nasal care and possibly surgical procedures A healthcare professional can recommend a personalized treatment plan based on the type and severity of the condition.
