Nasopharyngeal polyps arising in the middle ear of the cat

Abstract
The clinical presentation, diagnosis and surgical treatment of four cats with nasopharyngeal polyps are described. In three cats the microscopic appearance of the polyps together with the finding of radiographic densities in the tympanic bullae point to the middle ear as the origin of these polyps. These are inflammatory lesions and it is suggested that they occur as the result of ascending infection from the nasopharynx. Experience has shown that, in spite of recurrence in some cases, simple traction rather than bulla osteotomy is the preferred method of treatment.
