Progressive inability to open the mouth developed in a cat after trauma to the head. Evaluation revealed a healed depression fracture of the left zygomatic arch and normal temporomandibular joints. Surgical exploration of the fracture confirmed a false ankylosis that developed between the depression fracture and the ramus of the mandible. Treatment included excision of the central portion of the zygomatic arch and a portion of the ramus. The cat regained normal function of its mouth.
一只猫头部受伤后逐渐出现无法张口的情况。评估发现左侧颧弓有愈合的凹陷性骨折，颞下颌关节正常。对骨折进行手术探查证实，凹陷性骨折与下颌支之间形成了假性关节强直。治疗包括切除颧弓中部和部分下颌支。这只猫恢复了正常的张口功能。
