📝 “What is the Gillies Approach for Open Reduction of a Zygomatic Arch Fracture?”

- 11.17.24Quick Review #254 - #surgery #surgeon #doctorgallagher #oralsurgery #oralsurgeon #omfs #dentist #dentistry #dental The Gillies Approach is a classic surgical technique used to access the zygomatic arch for the treatment of isolated zygomatic arch fractures, particularly for open reduction. This method is minimally invasive and aims to restore the fractured arch to its normal anatomical position with minimal scarring and soft tissue disruption.Steps of the Gillies Approach1. Incision:• A small temporal incision (about 2-3 cm) is made within the hairline at the temporal region to minimize visible scarring. The incision is positioned above the zygomatic arch, posterior to the lateral orbital rim.2. Access and Instrumentation:• The dissection proceeds through the superficial layers to the deep temporal fascia. Care is taken to avoid injury to the superficial temporal artery and temporal branch of the facial nerve.• A Gillies elevator (a curved blunt instrument) is inserted under the deep temporal fascia and advanced inferiorly toward the fractured zygomatic arch.3. Reduction of the Fracture:• The elevator is gently leveraged to lift and reposition the zygomatic arch back to its proper anatomical alignment.• Reduction is confirmed through tactile feedback, visual symmetry, or intraoperative imaging such as fluoroscopy.4. Wound Closure:• The incision is closed in layers, ensuring meticulous closure of the fascia and skin to minimize complications such as hematoma or infection.Indications• The Gillies approach is particularly suitable for isolated zygomatic arch fractures where the primary concern is aesthetic and functional restoration of the arch without requiring extensive exposure of adjacent structures.Advantages• Minimally invasive: Results in minimal scarring since the incision is hidden within the hairline.• Efficient access: Directly targets the zygomatic arch while preserving surrounding structures.• Reduced soft tissue disruption: Decreases the risk of complications such as nerve injury or excessive bleeding.Limitations• It may not provide adequate exposure for complex fractures involving other parts of the zygomaticomaxillary complex (ZMC).• The approach requires experience to avoid iatrogenic injury to adjacent structures, including the temporal branch of the facial nerveReferences:1.
