Rhinitis

Contributor(s): Philip K Nicholls, Nicki Reed

Introduction

  • Cause: inflammation of nasal passages.
    • Usually sequelae to viral upper respiratory tract infection.
    • May be seen in association with inhaled allergens.
  • Signs: sneezing, nasal discharge.
  • Diagnosis: signs, rhinoscopy, radiography, biopsy.
  • Treatment: treat underlying cause and symptomatic management.
  • Prognosis: guarded for resolution of signs.

Pathogenesis

Etiology

Predisposing factors

General

  • Depends on cause.

Pathophysiology

  • Etiological agent   →   damages nasal mucosa   →   inflammatory reaction.
  • Damage to normal structure and immunological function of nasal mucosa   →   reduced defenses   →   bacterial overgrowth.
  • Inflammation and discharge often occlude aperture between frontal sinus and nasal cavity   →   frontal sinusitis.
  • Anatomical defects, neoplasia or foreign body   →   secondary infection.
  • Viral rhinitis   →   secondary bacterial infection.
  • Initially acute inflammation (may)   →   chronic hyperplasia of nasal mucosa   →   chronic rhinitis.
  • Exposure to allergen/irritant   →   inflammatory reaction.
