A degu named Chip came to the clinic. The owners’ main complaints were weight loss despite normal appetite and a “sticky” right ear. On examination the veterinarian noted mildly reduced body weight and a large amount of purulent material in the right external ear canal.
Chip was referred for CT imaging; blood tests were taken first and no contraindications to anaesthesia were found. CT confirmed the working diagnosis — middle ear infection (otitis media).
Chip then underwent video otoscopy to collect samples for bacterial culture and to remove purulent material from the middle and external ear. During flushing, the clinicians found a mass on the wall of the vertical ear canal. It was removed and sent for histology to rule out malignancy.
While waiting for culture results, Chip was started on broad-spectrum antibiotics — treatment cannot be delayed in this type of disease. He tolerated therapy well: active, sociable, appetite normal. When antibiotic sensitivity results returned, the drug he was receiving was a good match, and the removed mass was benign. Treatment lasted 6 weeks; purulent discharge resolved completely (follow-up video otoscopy), Chip gained weight and was discharged home under owner monitoring.
If you notice your pet becoming less active, losing weight, developing a head tilt, or discharge from the ear canal, do not delay a veterinary visit. The earlier the diagnosis, the sooner treatment can start and your animal can return to normal life.
