anyone know anything abut this I googled it and It came up with loads Jenna - Respiratory - Left Recurrent Laryngeal Neuropathy (LRLN, laryngeal paralysis, roaring) The larynx (voicebox) forms the passageway to the trachea (windpipe). For effective function, the larynx must be able to close while the animal is swallowing, and it must become very wide during maximal exercise, to afford the greatest airflow. Laryngeal paralysis, which is most common in horses taller than 16H, primarily affects the left side. For reasons that are not well understood, the nerves (the left recurrent laryngeal nerve) that serve the muscle that opens the larynx, begin to die. When nerve function is lost, the muscle is no longer stimulated, and so it atrophies. The end result is that the left side of the larynx becomes paralyzed and can no longer open normally. This prevents the horse from breathing freely during intense exercise. The degree of laryngeal paralysis is very minor in a lot of horses (up to 80%), and severe in up to 10% of horses. It's a problem that worsens with age, so the percentage goes up in the higher age brackets. This is one reason why older horses can't work as hard as young racehorses. Owners may suspect that their horses have LRLN because the collapse of the larynx during inspiration causes them to make a distinctive roaring noise, somewhat akin to a St Bernard panting or the sound of sawing timber. In some cases, the sound is more like whistling. LRLN is more of an aesthetic problem in horses that do not compete at maximum capacity. It is not until horses are competing in races greater than one mile, high goal polo, or upper level three-day events, that laryngeal paralysis will actually interfere with performance. In rare cases, the right side can get bad in addition to the left, and the larynx collapse. These horses can no longer perform without surgical intervention. www.horseandhound.co.uk/horsecare/1370/34656.html
