Abstract

A 5-year-old castrated male Maine Coon cat presented with chronic otitis on the right ear. The clinical signs, scratching and head shaking, were recurrent despite symptomatic treatment, including antibiotics and antifungal agents. Video otoscopic examination and computed tomography (CT) examination revealed a polyp in the right ear canal. The polyp was removed via per-endoscopic trans-tympanic traction (PTT) with a grasping forceps. After treatment, Horner's syndrome occurred in the right eye but spontaneously resolved a week later. The mass was diagnosed as inflammatory polyp with a fibrovascular stroma containing plasma cells, lymphocytes, and neutrophils. All clinical signs were improved, and no recurrence was observed after 3 weeks of follow-up. This case report demonstrates that CT scan is effective in identifying the margin of polyp and PTT technique is non-invasive method for treating inflammatory polyp in cats without severe complications.
