AI Article Synopsis
- Maxillofacial fractures lead to over 400,000 emergency department visits annually in the U.S., with CT scans being the standard diagnostic method but having downsides like radiation exposure and cost.
- A study compared linear-probe ultrasound to CT and plain film X-ray for diagnosing infraorbital rim fractures, using CT as the benchmark.
- Results indicated that linear-probe ultrasound had a sensitivity of 92.9% and specificity of 90.0%, making it a reliable alternative diagnostic tool compared to traditional X-ray and CT for these fractures.
Article Abstract
Background: Maxillofacial fractures are a common cause of visits to emergency department, accounting for more than 400,000 annual visits in the United States. Gold standard diagnostic tool is conventional computerized tomography (CT) or 3DCT reconstruction. However, the disadvantages of CT are radiation exposure, unavailable in some hospital and expensiveness. Whereas the bony structures overlap is a problem in diagnostic when using plain film X-ray. The objective of this study is to show the accuracy of a linear-probe ultrasound compared to computed tomography and plain film X-ray in diagnosis of infraorbital rim fracture.
Methods: Patients clinically suspected of an inferior orbital rim fracture underwent linear-probe ultrasonographic investigation, plain film X-ray and CT. CT was used as gold standard in this diagnostic study. A radiologist and senior resident of plastic surgery were the examiner and interobserver for comparison.
Result: A total of 34 patients with suspected infraorbital rim fractures were investigated. Sensitivity of the linear-probe ultrasonography versus CT in the detection of infraorbital rim fracture was 92.9% (95% CI 66.1-99.8), specificity was 90.0% (95% CI 68.3-98.8), positive predictive value was 86.7% (95% CI 59.5-98.3), negative predictive value was 94.7% ( 95% CI 74.0-99.9), accuracy 91%.
Conclusion: Linear probe ultrasonography is a good diagnostic tool and has better reliability than the plain film X-ray and can be used as alternative to CT in inferior orbital rim fracture.

We describe an oculofacial injury phenotype manifesting as a cleavage plane following the orbitomalar ligament in 5 cases. Across these cases, curvilinear wounds followed the course of the orbitomalar ligament, running clean planes through orbicularis oculi down to the infraorbital rim and arcus marginalis. One case involved bilateral orbitomalar ligaments, and 1 case involved the inferior canaliculus.

Background: Most facelift techniques have limited effect on the nasolabial fold and the more medial part of the face. The facial rejuvenation enhancing cheek (FRENCH) lift can treat both jowl sagging and midface deflation by a monobloc vertical and oblique displacement of the anterior column of the face through an extended subcutaneous dissection.
Objectives: To explain the surgical technique and to show its efficacy on the nasolabial fold, jawline and infraorbital rim.
Refining Operative Indications for Zygomaticomaxillary Complex Fracture Repair.

Division of Plastic and Reconstructive Surgery, The Warren Alpert Medical School of Brown University, Providence, RI, USA.
Study Design: Case-control.
Objective: Although zygomaticomaxillary complex (ZMC) fractures are among the most common facial injuries, the optimal approach to management remains controversial. This study analyzes the relationship between displacement measures derived from pre-operative CT imaging and clinical symptomatology to enhance surgeon understanding of the need for operative intervention.

The zygomaticomaxillary complex is integral to facial aesthetics and is frequently involved in facial fractures. These injuries often necessitate surgical intervention, with open reduction and internal fixation being the standard treatment. This article presents a novel philosophy for managing zygomatic fractures, emphasizing the "Scarless Surgery" technique.
