A Pekingese dog was presented for evaluation of head trauma with ventral head and neck swelling, puncture wounds, palpable mandibular fractures, and loss of menace, severe miosis, and loss of palpebral reflex of the right eye. Computed tomography confirmed multiple mandibular and zygomatic fractures, a right ear canal avulsion, and a complete right tympanic bulla fracture with ventral displacement. The tympanic bulla fracture was managed conservatively. Topical lubrication and antibiotic ointment was prescribed for the right eye. A subtotal hemimandibulectomy was performed to address the mandibular fractures. A temporary oesophagostomy feeding tube was placed. No short-term complications developed as a result of the fractured bulla and avulsed ear canal being left in situ, and no complications were reported 18 months after the injury. To the authors' knowledge this is the first report of a traumatic tympanic bulla fracture in the dog.
一只北京犬因头部外伤前来评估，其头部腹侧和颈部肿胀、有穿刺伤、可触及下颌骨骨折，右眼出现威胁反射消失、严重瞳孔缩小及睑反射消失。计算机断层扫描证实存在多处下颌骨和颧骨骨折、右耳道撕脱以及右鼓室完全骨折并伴有腹侧移位。鼓室骨折采用保守治疗。为右眼开了局部润滑和抗生素眼膏。进行了下颌骨次全切除术以处理下颌骨骨折。放置了一根临时食管造口饲管。鼓室骨折和耳道撕脱未作处理，未出现短期并发症，伤后18个月也未报告有并发症。据作者所知，这是犬外伤性鼓室骨折的首例报告。
