A Persian cat was presented with open-mouth jaw locking. It was suspected that abnormal extrusion of the maxillary canine teeth caused contact with the mandibular canine teeth on closure of the mouth, resulting in levering forces that may have led to increased symphyseal mobility, temporomandibular joint laxity, rotational movement of the left mandibular body and locking of the left coronoid process lateral to the zygomatic arch. Symphysiotomy, symphysiectomy, circumferential and interdental wiring, and intraoral resin-based splint application were performed to achieve intermandibular arthrodesis. Following removal of all devices, no further jaw locking episodes were reported during a 33-month follow-up period.
一只波斯猫出现了张口时颌骨锁定的情况。怀疑上颌犬齿异常突出，导致闭口时与下颌犬齿接触，从而产生杠杆力，这可能导致下颌联合处活动度增加、颞下颌关节松弛、左下颌体旋转运动以及颧弓外侧的左冠状突锁定。为实现下颌间关节固定，进行了下颌联合切开术、下颌联合切除术、环周和牙间结扎以及口腔内应用树脂基夹板。在移除所有装置后，在33个月的随访期内未再报告颌骨锁定发作情况。
