My dog's chronic sinus infection: Is surgery needed if meds fail?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | 14 years and 11 months old

After nasal swab,CT scan,radiography,rhinoscopy; doc said surgery.He said he couldnt see anything bc of the infected disharge in the nose so biopsy may give wrong results.He has disharge for months.He also had a tooth extracted from where the discharge started and a pocket burst and dried out under the related eye.All this time, we thought it's an infection which also caused a bone erosion. I want to know if any sinus infection has to be operated?Can it be infection that wont go away with drugs?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Spike! I am assuming since you have had extensive diagnostics done that you and Spike are in the care of a specialist. If there is an infection in his sinuses then it could be resistant or be fungal. Fungal infections do not respond to antibiotics and the Vet would want a diagnosis before starting anti-fungals. My concern is for a tumor due to Spike's age. I can't view your image as it is very very small and out of focus. I would ask what other imaging like an MRI can be done to confirm if there is a tumor or not. Also I would just do the scope with the hope that they will see the tumor and are able to get a good culture and biopsy. If they can't then consider surgery. I wish you and Spike the best!
