Feline nasopharyngeal polyps.
In summary, an ideal diagnostic plan for cats with suspected FNPs should include a thorough anesthetized oropharyngeal examination, otoscopic examination, and imaging studies, which may consist of a bulla radiographic series or specialized imaging studies such as CT or MR scans. In general, if signs indicative of otitis media are present, ventral bulla osteotomy should be advised. As a result of the distinct appearance of FNPs, a preoperative biopsy is not indicated in all instances but should be considered if there are atypical features to the history or presentation. Traction-avulsion of polyps through the external ear canal or auditory tube from the oropharynx may have a lower success rate than traction-avulsion combined with ventral bulla osteotomy. If the veterinarian opts to treat FNPs by traction-avulsion alone as a result of financial constraints imposed by the client, the client should be strongly cautioned regarding potential recurrence. Postoperative complications are possible with any treatment option, but neurologic impairment, including Horner's syndrome, facial neuropathy, and hypoglossal neuropathy, is significantly more likely after surgical intervention by ventral bulla osteotomy than after traction-avulsion alone. A high percentage of these complications are self-limiting. In all instances, appropriate culture and sensitivity and biopsy specimens should be collected so as to enable provision of appropriate postoperative care. Antibiotic therapy should be provided based on culture and sensitivity test results. The use of postoperative steroids to prevent recurrence is controversial.
