摘要：There have been few reports about temporohyoid osteoarthropathy in Japanese horses. The aim of this study was to describe the symptoms and management of temporohyoid osteoarthropathy and to investigate its association with crib-biting behavior, which is commonly observed in Japanese horses. The data concerning case details, signs, diagnosis procedures, treatment, and outcomes were collected retrospectively from the medical records of 11 Thoroughbreds with temporohyoid osteoarthropathy. The trainers and owners were asked whether the horses had displayed crib-biting behavior. Nine of the horses were diagnosed by guttural pouch endoscopy, and two were diagnosed by skull radiography. Eight horses were treated medically, of which three (37%) showed improvement; the other three horses underwent ceratohyoidectomy, with two (67%) showing improvement. Crib-biting behavior was observed in eight (73%) of the horses. A comparison of data regarding crib-biting behavior among 437 Thoroughbreds from six local riding schools indicated a significant association between temporohyoid osteoarthropathy and crib-biting behavior: the odds ratio for a horse with temporohyoid osteoarthropathy to exhibit crib-biting behavior compared with the general population was 12 (95% confidence interval, 3–45), and horses exhibiting crib-biting behavior were significantly more likely to have temporohyoid osteoarthropathy (P<0.001, Fisher’s exact test). This suggested that crib-biting behavior may be a risk factor for temporohyoid osteoarthropathy..
