Sinusitis (Inflammation of the Paranasal Sinuses)
In sinusitis, one or more of the air-filled paranasal sinuses become inflamed, often with an accumulation of secretion or pus. It arises primarily after airway infections or secondarily through diseased cheek-tooth roots whose tips reach into the maxillary sinus.
Veterinary care required
This condition belongs in veterinary diagnosis and treatment. Compounds are at most supportive.
Priority · vet & management
Diagnosis and therapy need veterinary clarification, usually via endoscopy and radiography (also to check for dental involvement); depending on the cause, flushing or dental/surgical measures are needed. Complementary feeds can only support the airway mucosa adjunctively and do not replace treating the cause.
Possible causes
- · secondary to respiratory infections (primary sinusitis)
- · diseased cheek-tooth roots (dental sinusitis)
- · cysts, polyps or masses
- · impaired drainage of secretions from the sinuses

Equiterna's take
Equiterna always thinks of sinusitis from the tooth as well — the close anatomical relationship to the cheek-tooth roots makes the veterinary-dental work-up central.
