Diseased thyroids can cause respiratory distress, limited head and neck movement, and unsightly lumps in affected horses’ throat areas. In such cases veterinarians usually remove the thyroid under general anesthesia, but researchers recently developed a thyroidectomy technique for use in standing horses with simple sedation and local anesthesia. The results, they say, are a win-win for everyone.

“Our technique minimizes risk to the patient, reduces costs to the client, and limits complications arising from the procedure,” said Marco Marcatili, DVM, PhD, MRCVS, of the University of Glasgow School of Veterinary Medicine’s Weipers Centre Equine Hospital, in Scotland, and Pool House Equine Clinic in Lichfield, U.K.

Specifically, the researchers noted a marked reduction in the risk of recurrent laryngeal nerve neuropathy (RLNN, also known as “roaring”) after standing thyroidectomy compared to traditional thyroidectomy with the horse lying down under general anesthesia
