Nasopharyngeal polyps in the cat
Insights
Inflammatory nasopharyngeal polyps were identified in four cats, often linked to respiratory issues. Surgical removal was successful, with no observed recurrence in this small case series.
Area of Science:
- Veterinary Medicine
- Otolaryngology
Background:
- Nasopharyngeal polyps can cause respiratory distress in felines.
- Understanding the origin and clinical presentation is crucial for diagnosis.
Observation:
- Four cats presented with varying clinical signs, including chronic upper respiratory infection, coughing, retching, and noisy respiration.
- Polyps were consistently found attached to the pharyngeal opening of the Eustachian tube.
- No association with external or middle ear disease was indicated by examinations.
Findings:
- Inflammatory nasopharyngeal polyps can occur in cats.
- The polyps may originate from the Eustachian tube lining or tympanic bulla.
- Simple dissection allowed for polyp removal without major surgical complications.
Implications:
- This study highlights a potential cause of respiratory signs in cats.
- Early diagnosis and surgical intervention can lead to positive outcomes.
- Further research into the etiology of these polyps is warranted.
Abstract:
The occurrence of inflammatory nasopharyngeal polyps is described in a series of four cats. Two of the cats presented with classical features of chronic upper respiratory tract infection, in a third gradual onset of coughing and retching were the only clinical signs, while in the fourth only noisy respiration accompanied the growth. In each cat the polyp was attached to the pharyngeal opening of the eustachian tube and it is suggested that such masses arise from either the lining of the tube itself or that they may even find origin within the tympanic bulla. However, anamnesis and the subsequent clinical and radiographic examinations did not indicate that the polyps were associated with external or middle ear disease. Removal by simple dissection was effected without the necessity of splitting the soft palate in any of the patients and, though expected, recurrence has not yet been seen.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
