Abstract

A nine-year-old, male, neutered Tibetan terrier was evaluated for unilateral otitis externa associated with the history of a dog bite injury to the pinna five years prior. Examination findings of the left ear included severe inflammation, abundant purulent exudate and a polypoid mass, obscuring view of the horizontal ear canal and tympanic membrane. CT scan confirmed the visualised mass location and confinement to the ear canal. Aerobic otic culture revealed abundant colonies of Staphylococcus pseudintermedius and Corynebacterium species. Histopathology was consistent with a fibrous polyp. Otitis externa treatment provided minimal relief following mass removal, and the patient was re-examined. A transparent plastic foreign body lodged within the horizontal canal was identified and removed. The item was recognised as a cap used for packaging of topical treatments prescribed at the time of the original traumatic injury. All clinical signs resolved following removal of the foreign body and oral anti-inflammatory therapy.
