Fractured zygoma cases, primarily from assault, show tetrapod fractures as most common. While both open and closed reductions are effective, open reduction is linked to more incision complications, and closed reduction to higher facial deformity rates.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Trauma Surgery
  • Plastic Surgery

Background:

  • Fractured zygoma (cheekbone) injuries are a significant concern in trauma care.
  • Understanding epidemiology, fracture patterns, and treatment outcomes is crucial for effective management.
  • Global data comparison aids in refining treatment strategies for zygomatic fractures.

Purpose of the Study:

  • To review fractured zygoma cases, analyzing epidemiology, fracture patterns, treatment modalities, and complications.
  • To compare findings with international data on zygomatic fractures.
  • To provide evidence-based insights into managing zygomatic fractures.

Main Methods:

  • A 10-year retrospective audit of hospitalized patients with fractured zygoma at Royal Hobart Hospital.

  • Exclusion of Le Fort fractures involving the zygoma.
  • Analysis of 263 fractured zygoma cases.

    • Main Results:

    • Assault was the primary cause of fractured zygoma, with alcohol as a significant contributing factor.
    • Tetrapod fractures were the most frequent pattern; plating was the most common fixation method.
    • Complications, including inferior orbital nerve dysfunction, occurred in 24.6% of cases, with open reductions showing higher complication rates when nerve dysfunction was excluded.

    Conclusions:

    • Both closed and open reductions are viable treatments for fractured zygoma, used in nearly equal patient numbers.
    • Closed reduction had a higher incidence of postoperative facial deformity, while open reduction had more incision-related complications.
    • Open reduction and internal fixation are recommended for unstable, displaced, or comminuted fractures; Silastic sheeting is favored for orbital floor defects with few complications.
