Unstable patients, in which any definitive procedure must be delayed, may be managed with temporary bony support (muzzle) and adjunct nutritional supplementation that bypasses the oral cavity. Mandibular and maxillofacial trauma is most successfully managed by early definitive fracture fixation as soon as the patient has been stabilized. (Reproduced with permission from Buchet M, Boudrieau RJ: Correction of malocclusion secondary to maxillary impaction fractures using a mandibular symphyseal realignment in 8 cats. This method precludes attempting to realign the maxilla, which was stable. C, Repositioning of the mandible now allows appropriate occlusion. B, A mandibular symphyseal “shift” has been performed to realign the upper and lower arcades notice the step now present at the level of the symphysis and mandibular central incisors. A, Despite the stability present in this cat, a fracture of the maxilla has occurred and can be identified by wider positioning of the maxillary canine teeth and apparent mandibular displacement toward the right a small step also is noticed at the level of the central two maxillary incisors the mandible is unaffected, but the maxilla is shifted to the left (as an “impaction” fracture). Owing to the absence of circumferential bone, these injuries require special attention to reconstruct the supporting soft tissue structures.įigure 67-2 Many maxillary fractures are difficult to identify and are clinically stable. Similarly, fractures of or near the orbit may involve supporting structures of the eye. Recognition of mild nasal malalignment can be difficult when coexisting fractures of the mandible are present. Maxillary fractures may result in upward or lateral deviation of the nose. Swelling, pain on palpation, and nasal bleeding may be clues that nasal and maxillary fractures are present. Longitudinal fractures along the center of the nose often are stable and seem to be more frequent in cats than in dogs. 18 Fractures that involve the nasal turbinates may interfere with breathing. Nasal fractures may be difficult to diagnose, as these bone fragments usually are stable (Figure 67-2). Subtraction of the soft tissues and surrounding bony structures leaves just the left mandible to evaluate, which is rotated around the vertical and horizontal axes ( E–H) to better assess the fracture line, which identifies that a vertical fracture isolates the condyloid and angular processes. Coronal (C) and sagittal sections (D) show that the temporomandibular joint is unaffected. A three-dimensional reconstruction ( A–B, craniocaudal and lateral views) clearly shows the fracture of the coronoid process however, a vertical fracture that might include both condyloid and angular processes is more difficult to identify. 22(4):1416-21.Figure 67-1 Computed tomography (CT) scan of left mandibular ramus fracture.
