Has anyone heard of wally ear oil to prevent and help ear infections? ent or herbal docs?

What kind?: Ear oil is unlikely to prevent otitis media (middle ear infections) since the ear canal doesn't communicate with the middle ear. But, it may help with pain from a middle ear infection. For otitis externa (swimmers ear), there is no evidence to support using wally ear oil as prevention but i can't think of a reason why a drop in each ear once a week during swimming season would be harmful.
