Perfecting the Outcome of Nasal Bone Fracture in the Pediatric Population With a Navigation System

The orbit is a confined space with a defined bony structure. Bony protrusion into the ethmoid or maxillary sinuses by the blowout fracture can displace orbital tissues, including rectus muscles and adjacent fascial septae. Especially, reconstructing the orbit’s floor and medial wall can be challenging when the inferomedial strut or posterior bony ledge is affected, leading to a loss of critical anatomic landmarks and support. Correctly positioning an implant in the precise anatomic location can be challenging. Recent updates to the navigation system have addressed this issue. Despite its early application, using a navigation system in these orbital fractures advances plastic surgeons in a way that has more confidence and accuracy in surgical planning. The video demonstrates how these 2 can be combined in an operating room. Intraoperatively, the authors check the superior, anterior, and posterior ends of the medial wall fracture and the posterior end of the floor fracture. A single orbital implant was trimmed and reshaped to match defect measurements. The implant placement was meticulously executed to repair the fracture while ensuring the inferior oblique muscle was not injured. After confirming the correct placement of the implant, it was secured to the inferior orbital rim using a single screw. Depending on the medial orbital wall fracture depth or degree of soft tissue herniation, the authors used an artificial dermal matrix or trimmed absorbable mesh plate to cover the uppermost part of the medial wall fracture to prevent postoperative enophthalmos. Finally, a forced duction test was performed. Our study shows that navigation-assisted inferomedial orbital wall reconstruction using materials readily available in the market is safe and effective.

Is Gillies Temporal Incision Necessary to Successfully Reduce Zygomaticomaxillary Fracture Combined With Orbital Wall Fracture?

Gillies temporal approach has been widely used to reduce zygoma fractures. Traditionally, it is the preferred method to reduce the isolated zygomatic arch fracture. It can be combined with other approaches, such as subciliary and intraoral incisions for more complex zygomatic fractures, so-called tripod fractures. In this study, the author hypothesized that complex zygomaticomaxillary bone fracture reduction can successfully be achieved without Gillies temporal incision. The author retrospectively analyzed the medical records and 3D facial Computed Tomography (CT) scans of 80 patients who had orbitozygomaticomaxillary fractures that affected >3 sites among the frontozygomatic suture, zygomaticomaxillary buttress, zygomatic arch, and orbital walls from May 2021 to August 2023. A single surgeon performed all surgical operations. All fractures were reduced with 2 incisions, lower eyelid incisions (subciliary or subconjunctival) and intraoral incisions (gingivobuccal approach), within a week of the initial traumatic event. After sufficient exposure to fractured sites using 2 incisions, the author reduced the fracture with a bony hook at the inferior orbital rim, lateral wall, or Boise elevator at the intraoral incision. All cases were successfully corrected without any complications. In conclusion, the author can successfully reduce complex zygomaticomaxillary fracture combined with orbital wall fractures without temporal Gillies approach.

Usefulness of the Glove Finger Pad for Ultrasonography in Nasal Fracture Reduction

The treatment of nasal bone fractures involves closed reduction, in which the reduction position is generally evaluated indirectly by visual examination and palpation. While more direct evaluation methods using ultrasonography can improve treatment outcomes, ultrasonography of the nasal bones requires acoustic coupling materials to hold the entire ultrasonography probe in close contact with the nose. We report the use of the Glove Finger Pad, a homemade acoustic coupling material made from a medical glove. The Glove Finger Pad is easy to prepare and use and produces good images. We believe that the Glove Finger Pad will further enhance the usefulness of ultrasonography for the treatment of nasal fractures.
