This clinical report describes two horses with bilateral maxillary fractures following dental treatment. The fractures occurred during dental treatment by a veterinarian, and both had rostral, transverse, and complete bilateral maxillary fractures with instability and minimal displacement. The fractures were repaired using bilateral intraoral wiring with the patients under general anesthesia. The postoperative period was without complications and the fractures healed as expected. Maxillary fractures during or after routine dental treatment are rare, but can occur, especially in older horses. Appropriate sedation and, if necessary, regional nerve blocks might reduce the risk of iatrogenic fractures of the maxilla. General anesthesia must be considered for tooth extraction in horses that are difficult to restrain.
本临床报告描述了两匹在牙科治疗后发生双侧上颌骨骨折的马。骨折发生在兽医进行牙科治疗期间，两匹马均出现了双侧上颌骨向前、横向的完全骨折，伴有不稳定和轻微移位。在全身麻醉下，对患者采用双侧口腔内钢丝固定术修复骨折。术后无并发症，骨折如期愈合。常规牙科治疗期间或之后发生上颌骨骨折的情况很少见，但确实可能发生，尤其是在老年马匹中。适当的镇静，必要时进行局部神经阻滞，可能会降低上颌骨医源性骨折的风险。对于难以保定的马匹拔牙，必须考虑全身麻醉。
