Propofol 4mg/kg was administered IV for the induction of anesthesia and endotracheal intubation. A catheter was aseptically placed into a cephalic vein and the patient was then premedicated with dexmedetomidine 2µg/kg, and hydromorphone 0.04mg/kg/h as Continous Rate Infusion (CRI) intravenously (IV). Quick Assessment Tests (packed cell volume, total solids, blood urea nitrogen) and blood gas analysis were within normal limits. Abbreviated thoracic and abdominal ultrasounds were negative for effusion in the pericardial-, pleural-, or peritoneal spaces. Neurological examination of the cranial nerves showed no signs of traumatic brain injury. ![]() Positive direct pupillary light and menace responses were observed. The right eye appeared unharmed although slightly deviated and the nictitans membrane was prolapsed. Physical examination revealed moderate deformation of the right side of his face below the eye, at the level of the zygomatic arch. Vital parameters were within normal limits. CASE REPORTĪ 5-year-old intact male Labrador retriever was presented to the Emergency Service for evaluation of suspected facial fractures after rough play with other dogs and facial trauma. This paper reports a case of right zygomatic arch fracture in a 5-year-old male Labrador Retriever, diagnosed through 3D CT reconstruction treated surgically with Veterinary Cuttable Plates. Many different surgical implants can be used to repair those fractures (Boudrieau, 2005). Although non displaced zygomatic fractures can often be treated conservatively, depressed fractures and those compromising function or threatening ocular or neurovascular structures should be reduced and stabilized (Boudrieau, 2012). Dissatisfactory imaging could lead to improper diagnosis, lack of or incorrect treatment, which could be pernicious to the patient's restoration of function and cosmetic appearance (Boudrieau, 2005). Nowadays, computed tomography (CT) has become more available to veterinarians and more affordable to pets owners (Bar-Am et al., 2008). For many years, the only diagnostic imaging modality available to assess animals with maxillofacial fractures was conventional radiographic exam however, the skull is a difficult area to study radiographically due to its very complex bone structure which leads to superimposition of important structures and makes detailed examination of individual parts difficult. ![]() Miniplate fixation for repair of mandibular and maxillary fractures in 15 dogs and 3 cats. The central structure of the zygomatic arch passes lateral to the vertical ramus of the mandible and if fractured may depress into the mandible and alter mastication while caudal fractures may interfere with the function of the mandibular condyles ( Boudrieau & Kudisch, 1996 BOUDRIEAU, R.J. Cranially, the zygomatic arch contributes to the ventral and lateral rim of the orbit ( Newton, 1985 NEWTON, C.D. The zygomatic arch is constituted cranially by the zygomatic bone and by the zygomatic process of the temporal bone caudally and gives lateral contour to the face and protects important glandular and neurovascular structures. A trauma unit’s experience-1989 fraser B. Complex craniomaxillofacial trauma: evolving concepts in management. Skull fractures in dogs can be related to concurrent trauma to the brain, eyes, and both oral and nasal cavities and may result in loss of support for the orbit, damage to the eye or associated structures ( Gruss, 1990 GRUSS, J.
