Bilateral mandibular fractures in a 7 month old mixed breed dog
MetadataShow full item record
An approximately 7 month old intact male mixed breed dog presented to Cornell University's Small Animal Orthopedic Service for surgical evaluation of previously diagnosed traumatic bilateral mandibular fractures. Preanesthetic bloodwork disclosed abnormalities consistent with nutritional deficits and muscle trauma. The dog was anesthetized, and a CT scan of the dog's head disclosed two transverse, minimally comminuted fractures of the bodies of the left and right hemi-mandibles at approximately the level of the fourth premolars and first molars. A minimally displaced fracture of the vertical ramus of the left hemi-mandible and multiple tiny bony fragments in the temporomandibular joints were also noted. Internal fixation (bilateral plates and screws) was performed for repair of the mandibular fractures. The fractures of the left ramus and temporomandibular joints were left for second intention healing. The patient's prognosis was considered good for long term adequate masticatory function; however, development of osteoarthritis in the temporomandibular joints was considered likely.
