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:
- Young horses are more prone as they are susceptible to Strangles
- Following transient systemic Streptococcus infection
- Rarely fungal infections
- 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
- In sheep often due to Oestrus ovis infection
