Background: Zygomaticomaxillary complex fractures associated with ipsilateral naso-orbito-ethmoidal fractures are more complex injuries than isolated zygomaticomaxillary complex fractures. This injury pattern can have significant long-term morbidity if not recognized and treated appropriately during the initial operation. The purpose of this study is to compare mechanisms of injury, treatment, and outcome between patients with zygomaticomaxillary complex fractures and those with zygomaticomaxillary complex and ipsilateral naso-orbito-ethmoidal fractures.
Methods: A 5-year retrospective review of all patients treated with zygomaticomaxillary complex fractures at a level I trauma center was performed. Computed tomographic scans were reviewed to divide patients into those with zygomaticomaxillary complex fractures alone and those with zygomaticomaxillary complex and ipsilateral naso-orbito-ethmoidal fractures. Demographics, treatment protocols, outcomes, complications, reoperations, and length of follow-up were identified for both groups and compared to determine differences between these populations.
Results: A total of 245 patients were identified by the Current Procedural Terminology codes for zygomaticomaxillary complex fractures. One hundred eighty-five patients had zygomaticomaxillary complex fractures and 60 patients had zygomaticomaxillary complex/naso-orbito-ethmoidal injuries. The demographics for both populations were similar. There are differences between the groups with regard to mechanism of injury, operative findings, and techniques. The patients with zygomaticomaxillary complex/naso-orbito-ethmoidal fractures had higher rates of postoperative complications and deformities.
Conclusions: Patients who sustain a zygomaticomaxillary complex fracture associated with an ipsilateral naso-orbito-ethmoidal fracture have a higher incidence of postoperative complications and deformities. It is important to recognize this fracture pattern early to help minimize postoperative morbidity.

Department Head, Department of Orthopaedic Surgery, Xingtai People's Hospital, Xingtai, Hebei, China.
Purpose: Zygomaticomaxillary complex (ZMC) fractures are a prevalent form of craniofacial trauma. However, no universally accepted fixation method has been established to prevent postreduction displacement in ZMC fractures.
Methods: Computerized and additional manual searches of the Medline, Embase, Chinese National Knowledge Infrastructure, and Cochrane Central database for potential studies, published from inception to May 2024, were performed.
The Orbitomalar Ligament: A Cleavage Plane in Oculofacial Trauma.

December 2024
Section of Ophthalmology, Department of Surgery.
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: The posterior maxilla and skull base is a region with a complex anatomy. Accurate resection of the pterygoid plate is critical during a maxillectomy procedure. However, there is a paucity of functional and anatomical studies on the pterygoid plate and skull base.

Introduction: Maxillofacial injuries are usually associated with ophthalmic injuries that may be mild to severe, and may even result in loss of integrity of the orbital skeleton and impairment of the visual apparatus.
Aim: To evaluate the pattern of ophthalmic injuries associated with maxillofacial fractures in patients who reported to a tertiary care hospital, associated with a medical college in M.P, India.
Mobilization of the Maxillary Lateral Buttress to Connect the Infratemporal Fossa and Buccal Space in Sublabial Approaches.

Surgical access to tumors involving the infratemporal fossa (ITF) and adjacent regions can be challenging, and there is a continued need for novel approaches to complex tumors in this region. In this manuscript, we present a unique anatomical approach that allows contiguous exposure of the ITF and buccal space with mobilization of the lateral maxillary buttress. Laryngoscope, 2024.
