Zygomaticomaxillary

Posttraumatic and postsurgical sensory disturbance is a known complication of almost all zygomaticomaxillary (ZMC) complex fractures involving the infraorbital nerve, for which few treatments are effective. Our study used neurosensory assessments to evaluate the efficacy of melatonin on pain and nerve healing following ZMC surgery. Sixty-four randomly allocated ZMC fracture patients were prophylactically administered either oral melatonin or an identical placebo for 15 consecutive days. Pre- and postsurgical clinical parameters included subjective pain, numbness, and objective neurosensory function...

Attitudes towards healthcare in the NHS and in other Western healthcare systems have been changing dramatically in recent years. There is a significant movement calling for a shift from the traditional paternalistic model, with patients as passive recipients of treatments that are supported by objective and observable evidence, towards a more holistic approach, in which patients have agency, and treatments are tailored to the individual needs of a particular patient. Whilst patient safety and clinical effectiveness remain intrinsic to the traditional measurement of successful healthcare, Patient Reported Outcome Measures (PROMs) are increasingly being advocated as an important tool to uphold patient-centric care in the NHS...

OBJECTIVE: This study's objective was to assess and contrast the performance of several plating techniques in the treatment of zygomaticomaxillary complex (ZMC) fractures. Group A (Microplate System), Group B (Titanium Mesh System), and Group C (Absorbable Plate System) plating systems were the ones that were studied. MATERIALS AND METHODS: With 10 patients in each group, a retrospective analysis of 30 patients with ZMC fractures was done. The following information was gathered: fracture reduction, stable fixation, complications, and patient satisfaction...

BACKGROUND: The aim of this study was to evaluate the accuracy of the degree of fracture reduction after open reduction and internal fixation of Zygomaticomaxillary Complex (ZMC) fractures in the Saudi population of the Al-Baha region, using Gillies approach. Further comparison with preoperative and postoperative standardized computed tomography (CT) views with the calculation of residual deformity percentage, which remained after the ZMC rehabilitation. METHODS: A 5-year retrospective CT-based study on preoperative and postoperative axial CT scans of 46 male patients with ZMC fractures...

OBJECTIVE: This study aims to quantify the facial symmetry of surgically treated zygomaticomaxillary complex (ZMC) fractures through a new reliable three-dimensional evaluation method, which is crucial for improving post-operative aesthetic and functional outcomes. MATERIAL AND METHODS: Healthy patients and patients with surgically treated ZMC fractures were retrospectively reviewed. Using Brainlab Elements® the zygomatic bone and the orbit of each patient was segmented and mirrored...

The mandible occupies the lowest point on the face. When the lower face is struck by high blows with upward or obliquely directed force, the prominent bone of the face sustains severe damage. When combined with zygomaticomaxillary complex fractures, mandibular fractures, which frequently occur in parasymphysis, present a challenging clinical scenario. This combination often requires a collaborative strategy to ensure a proper diagnosis and all-encompassing care. In this case study, we discussed the alleged trauma case of a 30-year-old male who met with a road traffic accident due to a bike slip at around 8:30 p...

Background: Patients may be educated about facial fractures using two-dimensional computed tomography (2DCT); however, three-dimensional mixed reality (3DMR) goggles may improve patient education by delivering content in an immersive environment. Objective: To compare the effectiveness of 2DCT and 3DMR formats used for patient education on facial fractures, as measured by surveys. Methods: In this prospective, randomized, crossover study, video tutorials intended for facial fracture informed consent were created in 2DCT and 3DMR formats from a single CT data set of a zygomaticomaxillary complex (ZMC) fracture...

Zygomaticomaxillary complex fractures are very common in maxillofacial trauma and may be associated with fractures of the coronoid process. We report a case of dislocation of the coronoid process above a zygomaticomaxillary complex fracture locking the mandible. We also report the surgical management of this uncommon case and its follow-up.

Our study aimed to evaluate modified patient-specific surgical-guide-assisted precise treatment of unilateral comminuted zygomaticomaxillary complex (ZMC) fractures. The retrospective non-randomized study was conducted in a single hospital in China. All patients diagnosed with unilateral comminuted ZMC fractures between January 1, 2018 and December 31, 2022 were retrospectively reviewed. All patients underwent preoperative spiral computed tomography (CT). CT data were processed using software to DICOM format and transferred to Proplan CMF3...

BACKGROUND: The study aims to assess the safety and effectiveness of BoneTape™, a new resorbable bone fixation device, using a zygomatic fracture model in rabbits. METHODS: The study followed BoneTape™ samples and control (sham) groups over 2-, 6-, and 12-week periods post-zygomaticomaxillary (ZM) osteotomy and zygomaticofrontal (ZF) disarticulation. The osteotomized segments were analyzed for bone healing, inflammatory response, and tissue healing...

Zygomaticomaxillary complex (ZMC) fracture repair is one of the most common surgical procedures performed in craniomaxillofacial trauma management. Miniplates and screws are used to stabilize the fractured bone using small local incisions, however, these procedures are not infrequently associated with hardware-related post-operative complications. The amount of fixation hardware utilized varies depending on the fracture pattern and surgical judgment, with three-point fixation being the conventionally accepted treatment...

OBJECTIVES: This study used computed tomography (CT) to compare the bone thickness and density values around the zygomaticomaxillary, zygomaticotemporal, and pterygomaxillary sutures that are resistant to rapid maxillary expansion (RME) treatment according to age, sex, and cervical vertebrae maturation (CVM) stage. METHODS: The study included 200 paranasal sinus records obtained for medical diagnosis and examination in a radiology clinic. The records provided data on 110 males and 90 females aged between 4 and 28 years...

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...

This study investigated the anatomic features of the zygomatic-maxillary complex in patients with maxillary retrusion without clefts. Individuals were grouped, and craniofacial measurements were performed for 21 individuals with skeletal Class III malocclusion with maxillary retrusion (CIII) and 48 individuals from the control group (CG). We evaluated the predetermined hard-tissue and soft-tissue points of the facial profile in each group. Independent sample t-tests were performed to determine the differences between groups (significance set at P<0...

We report the case of a 35-year-old male patient who presented with a right zygomaticomaxillary complex fracture, which was five months old. It was associated with ectropion over the right eye. Diagnosis was made by clinical examination and confirmed by computed tomography, which included a three-dimensional reconstruction view. The patient was concerned about a projecting deformity over the right side of his face and blurring of vision. Surgical rationale of treatment was to easily access the surgical site for the correction of deformity and to achieve the desired facial contour and ectropion correction with uneventful postoperative healing...

OBJECTIVE: : To investigate the long-term effects of maxillary skeletal expander (MSE) treatment on functional breathing. OBJECTIVE: measures of breathing, the peak nasal inspiratory flow (PNIF), and peak oral inspiratory flow (POIF), and subjective measures of breathing, the visual analog scale (VAS) and nasal obstruction symptom evaluation (NOSE) survey, were used to investigate the long-term effects of MSE in functional breathing. Seventeen patients, mean age 19...

The zygomaticomaxillary complex and the orbital floor are commonly affected by mid-face fractures; their fractures pose challenges in reconstruction and can result in complications, such as enophthalmos. This study explores an intraoral approach with the help of a customized balloon technique and a contrast agent as an alternative to the conventional methods. A case report of a 67-year-old man with complex midfacial trauma is presented. The surgical process involved open reduction through an intraoral approach along with a transantral approach with the customized balloon technique...

BACKGROUND: One-point fixation was superior to the two and three-points fixation in minimally displaced zygomaticomaxillary complex (ZMC) fracture regarding the cost, invasiveness, scaring, number of wounds, and operation time. Accordingly, this study aimed to predict which one-point fixation is the most stable in managing minimally displaced ZMC fracture. MATERIAL & METHODS: This study simulated the different one-point fixation approaches on three ZMC models after fracture reduction and application of all forces exerted on the fractured area...

The authors present the case of a 15-year-old male who sustained a unilateral zygomaticomaxillary complex fracture and underwent open reduction and rigid internal fixation, for which a U-shaped elevator was utilized. The authors discuss techniques in reduction and fixation of zygomaticomaxillary complex fractures, focusing on the use of various elevators during reduction, including straight-type and curved elevators. The U-shaped elevator is a handheld tool with bilateral symmetrically curved ends that is seldom used, despite its specific benefits including nonslip serrated tips, symmetrical nature that allows for direct loading needed for accurate reduction, visualization of the fracture site, and avoidance of tissue compression during elevation...
