Sinusitis

  • Often undetected unless it causes facial deformity or a draining tract onto the skin
  • Seromucous sinuitis in not significant, often an extension of viral infection in nasal cavity
  • Purulent sinusitis tends to obstruct drainage -> chronic purulent sinusitis
  • Most important in horses due to their complex sinuses
  • Primary:
  • Secondary:
    • Most common sequel to rhinitis
    • Dental or periodontal disease (maxillary sinus)
    • Penetrating infections from dehorning wounds and fractures of facial bones (frontal sinus)
    • Expanding mass
  • Purulent inflammation of sinuses is likely to become chronic due to poor drainage
  • Inflammation may block the drainage of the sinuses and cause distortion of the overlying bones
  • May result in empyema, inspissated exudate, in horses
