BACKGROUND: M-shaped zygomatic arch fractures can usually be treated effectively through closed reduction. It consists of 2 fracture segments: the anterior zygomatic segment and the posterior temporal bone segment. In clinical practice, atypical M-shaped fractures are often encountered, in which the anterior and posterior fracture segments are discontinuous and separated. Closed reduction usually cannot achieve the desired anatomic reduction effect for this type of fracture.
METHODS: The preoperative design showed that the anatomic reduction of the posterior zygomatic arch fracture segment was hindered due to bone spurs in the most concave area of the anterior zygomatic bone fracture segment. Open reduction and fixation were performed to achieve anatomic reduction and restore facial symmetry. The fracture sites were exposed through a hemicoronal incision. After the bone spurs are removed, the posterior bone segment can be anatomically reduced. Absorbable plates were used for fixation.
RESULTS AND DISCUSSION: The patient's facial appearance was restored after the surgery. The postoperative computed tomography scan showed a good alignment of the fracture. The authors believe that for patients with high requirements for facial symmetry, the presence of atypical M-shaped fractures can indicate open reduction and fixation.
