This study investigated 15 horses diagnosed with temporohyoid osteoarthopathy (THO) and treated by ceratohyoidectomy between 2004 and 2012. The presenting complaint, duration and nature of the clinical signs, additional diagnostic procedures, and complications were reviewed retrospectively. Long-term follow-up on horses was used to determine prognosis. All horses were diagnosed by guttural pouch endoscopy. Follow-up was available for 14 horses that survived to discharge. Eight of 10 horses that were used athletically prior to surgery returned to previous levels of use. Persisting clinical signs included mild facial nerve paralysis (3/14; 21.4%) or head tilt (6/14; 42.8%) but these were not functionally limiting. It was concluded that equine THO affects a wide range of breeds, disciplines, and ages of horses, and has a variety of presenting clinical signs most commonly associated with vestibular and facial nerves. Prognosis following ceratohyoidectomy is good for resolution of ataxia but some cranial nerve deficits may persist.
本研究调查了2004年至2012年间15匹被诊断为颞舌骨骨关节病（THO）并接受甲状舌骨切除术治疗的马。回顾性分析了主诉、临床症状的持续时间和性质、额外的诊断程序以及并发症。对这些马进行长期随访以确定预后。所有马均通过咽鼓管囊内镜检查确诊。对14匹存活至出院的马进行了随访。10匹在手术前用于竞技的马中有8匹恢复到了以前的使用水平。持续存在的临床症状包括轻度面神经麻痹（3/14；21.4%）或头部倾斜（6/14；42.8%），但这些并未对功能造成限制。得出的结论是，马的THO影响多种品种、训练项目和年龄的马，并且有多种最常与前庭神经和面神经相关的临床表现。甲状舌骨切除术后共济失调的预后良好，但一些脑神经缺陷可能会持续存在。
