The noise was definitely URT in origin, localised to the nasal passages.

You don&#39;t <i style="font-weight:bold;">have to </i>charge &quot;quite a lot&quot;, do you?</p> <p>I haven&#39;t seen anything on your radiographs yet, but I&#39;m going to have a longer look now.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/112739?ContentTypeID=1Tue, 15 Apr 2014 16:31:43 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:5124eb41-bc8d-4bf9-aabb-3fbf8aaee026Tim Charlesworth<p>Hi Anthony, if symptoms persist then I would stop the antibiotics and steroids for a week or so then send the dog for a nasal CT examination. I have certainly missed FB&#39;s on first pass rhinoscopy even when I&#39;ve known that they were there (from CT or MRI). Targetted nasal biopsies can then be taken from any abnormal areas detected on the imaging. If that&#39;s not possible then you could try flushing through the nasal passages (although I suspect you did this at the same time as rhinoscopy) and sending the washings for cytology +/- Aspergillus PCR. If you&#39;re lucky you may even remove an FB!</p> <p>Good luck, these can be very frustrating!</p> <p>Tim</p><div style="clear:both;"></div>
