Cue 6 months of Otovent (Nasal Balloon) treatment and a follow up appointment halfway through the treatment, with significant improvement in the hearing test (though still below the level expected), which I was sure would be the case; TV volume a lot lower and true selective hearing.
Well the last hospital appointment started with meeting the consultant, a look at his ears, a determination that he still had fluid behind the ear drums and a recommendation that he have a small operation to insert a grommet into each ear drum.
The off we went for his hearing test and then back to the consultant who reported with a surprise in his voice that Aden's hearing was now normal but that he did indeed still have fluid behind the ear. How much is not quantifiable just a view of, fluid behind the ear drum = yes/no
Much more difficult to sell the operation at that point, but as the consultant put it, "we cannot say what the long term effect of fluid behind the ear drum is, even though his hearing is now normal"
The next 4 months will be interesting to see what will happen. He will have another hearing test and check for fluid behind the ear before the operation but he is now on the waiting list and we are continuing the Otovent treatment.
