Causes of Vestibular Disease in Horses
Vestibular disease in horses can be caused by various factors, leading to balance and coordination issues. The most common causes include temporohyoid osteoarthropathy and head trauma. Temporohyoid osteoarthropathy is a chronic condition characterized by bony proliferation of the temporohyoid joint, which can result in joint fusion and subsequent vestibular dysfunction. Head trauma, such as basilar skull fractures, can also lead to vestibular nerve disease in horses.
In addition to these primary causes, there are other conditions that can contribute to vestibular disease in horses. Equine protozoal myelitis, neoplasia, brain abscess, West Nile virus, eastern equine encephalitis, and parasitic migration are among the possible underlying factors. It is important for horse owners and veterinarians to be aware of these potential causes and to consider them when diagnosing and treating vestibular disease.
To summarize, vestibular disease in horses can be caused by temporohyoid osteoarthropathy, head trauma, and other conditions. These causes can result in a range of clinical signs associated with balance and coordination issues. By understanding and addressing the underlying causes, veterinarians can better diagnose and develop appropriate treatment plans for horses affected by vestibular disease.

Clinical Signs of Vestibular Disease in Horses
Vestibular disease in horses can present with a range of clinical signs that indicate issues with balance and coordination. Recognizing these signs can help horse owners and veterinarians identify and diagnose vestibular disease early, allowing for appropriate treatment and management.
The most common clinical signs of vestibular disease in horses include:
- Head tilt: A noticeable tilt of the head to one side, often towards the affected ear.
- Nystagmus: Involuntary eye movements, which may be horizontal, vertical, or rotational.
- Recumbency/leaning: Preference to lie on the side of the lesion, with the horse leaning or falling to one side.
- Circling: The horse may continuously circle towards the side of the lesion.
- Ventrolateral strabismus: Misalignment of the eyeball, with one eye deviating downwards and outwards.
- Ataxia: Lack of coordination, with the horse appearing unsteady or stumbling.
- Facial nerve paralysis: Weakness or paralysis of the muscles on one side of the face, leading to drooping or asymmetry.
These clinical signs can vary in severity depending on the underlying cause and the progression of the disease. It’s important to note that not all horses with vestibular disease will exhibit all of these signs, and the presence of one or more of these signs does not necessarily confirm a diagnosis of vestibular disease. Diagnostic tools and thorough evaluations by veterinarians are necessary to determine the specific cause of the clinical signs and provide appropriate treatment.

Diagnosis and Treatment of Vestibular Disease in Horses
Vestibular disease in horses can present with a variety of clinical signs, making accurate diagnosis crucial for effective treatment. Veterinarians utilize a range of diagnostic tools to identify the underlying cause of the vestibular disease and determine the appropriate course of action. These diagnostic methods include endoscopy of the guttural pouches, radiographs, computed tomography (CT), and assessment of spinal fluid.
Endoscopy of the guttural pouches allows for a thorough examination of this area, which can be a potential site of infection or inflammation causing vestibular disease. Radiographs provide valuable insight into the skull and can reveal any fractures or abnormalities that may be contributing to the condition. CT scans offer detailed cross-sectional images, aiding in the identification of structural abnormalities or lesions affecting the vestibular system. Assessment of spinal fluid can help detect any signs of infection or inflammation that may be impacting the nervous system.
Once a diagnosis has been made, treatment options can be determined based on the specific condition and its severity. Conservative medical management is often the first-line approach and may involve the use of broad-spectrum antibiotics to target infections, as well as non-steroidal drugs to alleviate inflammation and pain. In some cases, surgical intervention may be necessary to address the underlying cause of the vestibular disease. Surgical procedures can include the removal of a portion of the affected bone or ceratohyoidectomy, depending on the location and nature of the condition.
The prognosis for horses with vestibular disease varies depending on the severity of the condition, the effectiveness of the treatment, and the underlying cause. It is crucial for horse owners to work closely with their veterinarian to ensure proper diagnosis and develop a comprehensive treatment plan tailored to the individual horse’s needs. Early detection and intervention can greatly improve the chances of a successful outcome and help manage the clinical signs associated with vestibular disease.
