Allergic Rhinitis and Its Role

• Allergic rhinitis involves inflammation of nasal passages due to allergens, causing congestion and impaired mucociliary clearance.

Impact on Upper Respiratory Tract Infections (URTIs)

• It predisposes individuals to recurrent URTIs by disrupting normal nasal defense mechanisms, increasing susceptibility to infections.

Connection to Sinusitis

• Allergic inflammation can block sinus drainage pathways, leading to sinus infections, both acute and chronic.

Link to Otitis (Middle Ear Infections)

• Eustachian tube dysfunction from nasal inflammation can cause fluid buildup and infections in the middle ear.

Summary of Interrelated Mechanisms

• Allergic rhinitis creates a cycle of inflammation and infection involving the nose, sinuses, and ears.

Relevant Medical Specialties and Management

• ENT specialists and allergists can manage these conditions through allergy management, infection control, and symptom relief.
