BROWSE NOW >>> Now based in France, she aims to present the most fascinating aspect of equine science: the story it creates. The alternative is to remove the weak arytenoid; however, that increases the risk of food and water going down the wrong pipe. In some cases the suture loosens, or the cartilage starts to tear loose from it, and the flap falls back into the airway; the surgeon can try again with a suture in a new spot. Conservative treatment with anti-inflammatories can help relieve both issues.For treating DDSP conservatively, researchers have developed a special collar, Couëtil says, that looks like a cribbing strap and helps prevent displacement. Noisy breathing often means compromised breathing, due to a blockage in the upper airways that inhibits proper airflow. As the nerve degenerates, the muscle atrophies, and the horse is less able to open his airway. “This makes him breathe more deeply through increased resistance, like he would during exertion, and it magnifies the abnormalities.”If that doesn’t work, however, a dynamic endoscopy might reveal the problem. Occasionally, these disorders result from injury or infection, but most of the time affected horses are born with them. BROWSE NOW >>> “If the horse has a mild abnormality and is a pleasure horse, he’s going to be just fine.”Couëtil agrees: “If the exercise isn’t strenuous, then they’re getting enough air and aren’t feeling stress or pain.”Some upper airway noises resolve with medical treatment alone, says Couëtil.
Most horses who have this surgery overcome this risk; they cough for a few days or weeks, then adjust and learn to swallow safely. After undergrad studies in science, journalism, and literature, she received a master's degree in creative writing. Roaring is seldom a significant problem for a jumper, for example, because his maximum efforts come in short bursts as he approaches and clears each jump.
Resting endoscopies can reveal most upper airway disorders, showing abnormalities such as an unresponsive side of the larynx, an out-of-place epiglottis, or a soft palate that rises during exhalation. “Sometimes the whole pharynx collapses,” he adds.Malformations can create respiratory noise, as well, he says. This article first appeared in the October, 2000 issue of The first step is a resting endoscopy, Parente says, in which the veterinarian inserts a small, lighted camera into the standing horse’s airways to visualize tissue function during inhalation and exhalation. An event horse running cross-country may be more seriously affected (especially at upper levels, where speed is a factor) because fatigue will set in; as it does, the airway will become increasingly restricted. Recently sedated horses often make snoring sounds. In some cases, the epiglottis is involved: The epiglottis is anchored by a loose membrane that lets it flip up over the larynx when the horse swallows; if that membrane is too loose, it can slip over and trap the epiglottis.

But when a noise seems unusual or repetitive, or if your horse is struggling to perform, it’s worth getting a veterinary evaluation.
Learn about the three most common noise-making pathologies and how they’re treated.The nasopharynx isn’t a tissue structure but, rather, a passageway formed by muscles and other structures.
