Veterinary Clinical Medicine-I (General and Systemic)

OBSTRUCTION OF THE NASAL CAVITY

• Obstruction of nasal cavities is rare in farm animals.

Etiology

• Acute rhinitis
• Granulomatous lesions caused by a fungus “ Rhinosporidium”
• Lesions caused by blood flukes “Schistosoma nasalis”
• Foreign bodies entering the nasal cavities when the animal rubbing its nose against objects to relieve irritation of acute allergic rhinitis
• Neoplasms of olfactory mucosa
• Lesions usually occur in the posterior nares & are usually unilateral & may be bilateral

Clinical findings

• In cattle & pigs there is severe inspiratory dyspnea
• The animal is excited & breathes through mouth
• Loud noise “sound” occurs in each inspiration
• Serious bloody stained nasal discharge “when there is foreign bodies, or purulent exudative nasal discharge when there is allergic rhinitis”
• Snorting & shaking of head

Treatment

• Treat the cause & remove the foreign bodies by a long forceps if it is accessible
• Administration of iodine preparation in chronic nasal obstruction as pot.iodide or sodium iodide
