The black, hard stuff needs to come out. Warm oil and compresses can help soften it, then you can use a wash cloth or cotton ball to remove the hard material. It is important to get this out of the way so that medications can reach the bacteria underneath. It appears that Dexoryl contains both an antibiotic and an anti-inflammatory, and should be able to treat the infection. However, some bacteria can be particularly nasty and occasionally pets need oral or injectable antibiotics to get over it. Cats also commonly get ear mites that can cause an infection, so Melcho should be treated for mites. Another potential cause for the infection is polyps that grow deep down in the ear. The swelling under the cheek should definitely be checked by a vet if it does not go down in the next 24-48 hours.
