G.B.
I am rather opinionated about ear infections but you asked...lol.
My 1 year old grandson was deaf. The ENT decided to go in and put tubes in to see if it helped with any hearing at all. The hearing test had shown no hearing for any tones. When the doc got inside he spent most of the time clearing debris from ear infections that the antibiotics had not touched because they had not been given long enough or something. he could not imagine that the antibiotics would leave this kind of mess.
Once the doc cleaned out the canals my grandson can hear. So I am pro antibiotics for even extended time. If the ear infection is not cleared up then damage is happening inside the ear canal and it might be life long if left untreated.
When bronchitis happens the goo has to exit the body somewhere, the eyes, the ears, the throat, etc....so if it chooses the ears then the ears, along with Sudafed and other meds can really make the goo thinner and easier to get rid of.
