Widely abducting laryngeal cartilages. Audible wheeze on inspiration. First thoughts were some kind of obstructive airway, so tracheal suction performeden-USTelligent Community 10https://www.vetsurgeon.org/thread/39235?ContentTypeID=1Thu, 16 Jun 2011 09:41:33 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:feba4b8e-81a6-45e4-99e2-50205ad8b5edMarie Kubiak<p>Could it be that this was a long-standing subclinical issue and airflow was fine in normal health but acute pneumonia developed as a completely separate issue and caused the clinical signs. Narrowed airway presence could accelerate progression as no compensation ability??? Very unusual!</p> <p>I&#39;m jealous of your odd cases then- I seem to see the same things over and over in chickens, repro and respiratory issues with the odd fracture to keep me occupied.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/39220?ContentTypeID=1Wed, 15 Jun 2011 22:31:14 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:1a462b1d-0bf3-4f68-976f-c532ca6768b1Martin Jones<p>Marie</p> <p>Thanks for the post. The syrinx was indeed&nbsp;flattened, and looked normal. This was an inch or so in front, with a unilateral crease and collapse on the right side. I did take some pics, but they really didn&#39;t capture the moment, so to speak.</p> <p>What&#39;s confusing me a little is that I expected to find some evidence of an obstructive airway disease - and did - but it just looked old and didn&#39;t fit with the sudden onset. I guess we&#39;re&nbsp;well used to chronic things being presented acutely, which have obviously just gone from being compensated to decompensation, but this bird didn&#39;t fit with that.</p> <p>I used to limit my veterinary activities with chickens to prolapse and PTS - generally in the same patient - but in the last few years I&#39;ve made a concerted effort to learn and to expand my abilities. Unfortunately, they seem to die with the same frequency and I keep seeing stuff I don&#39;t understand. One day I&#39;ll either become a specialist or just give up.......</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/39210?ContentTypeID=1Wed, 15 Jun 2011 17:50:53 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:0fe5eea8-511c-45d1-b83e-a333e69eb87aMarie Kubiak<p>The syrinx is dorsoventrally flattened so looks very different to mammal bifurcation. Can you post pics?</p> <p>Marie</p><div style="clear:both;"></div>
