Management of Zygomatic Fractures in Young Patients: Technical Modifications for Aesthetic and Functional Results

Outcomes of Non-surgical Management of Zygomaticomaxillary Complex Fractures

Introduction

With little evidence available in the literature, this study tries to clinically determine the efficiency and outcomes of non-surgical management of post-traumatic Zygomaticomaxillary complex (ZMC) fractures.

Materials and Methods

One hundred and three patients with post-traumatic isolated ZMC fractures managed conservatively for various reasons were identified. The patients were classified based on the Zingg et al. criteria into Types A, B, and C. We evaluated the resolution of signs and symptoms of six standard parameters over 6 months-persistent pain, restriction in mouth opening, infraorbital nerve (ION) paresthesia, aesthetic deformity, infraorbital step deformity with associated tenderness on palpation, and ophthalmic status. The study variables were then statistically analyzed using Cochran's Q test with an associated confidence interval of 95%.

Results

A six-month follow-up revealed persisting residual deformities for all three groups. However, Type A and Type B showed significant improvement in pain reduction, mouth opening, and infraorbital nerve (ION) paresthesia. No significant improvement was noted in any of the groups for aesthetic deformity, infraorbital step deformity, and ophthalmic status. Type C, which had comminuted fracture patterns, exhibited significant defects in all the parameters. Significant inter-variable relationship between certain paired parameters was also observed.

Conclusion

The Type A group is most suited for non-surgical management. Type B with a mono-bloc fracture is a crucial group that demands broader, long-term studies to extract a proper treatment protocol. Type C with severe fracture displacement validates surgical correction.

Removal of an Intraosseous Venous Malformation of the Maxilla via a Transoral-transconjunctival-Transcaruncular Approach

Intraosseous vascular anomalies represent less than 1% of all bony tumors. When they involve the maxillofacial skeleton, these masses may cause substantial morbidity and aesthetic concern. Herein, we highlight a case of a maxillary intraosseous venous malformation manifesting as functional lacrimal duct obstruction with epiphora, sinus pressure, and increasing medial canthal/maxillary fullness over 2 years in a young, healthy woman. Surgical excision of the lesion was accomplished without a skin incision by coupling a transoral, midface degloving technique with a transconjunctival-transcaruncular approach. This minimally invasive technique led to complete resolution of symptoms and a satisfactory cosmetic outcome, without a cutaneous scar.

Surgical management of isolated orbital floor and zygomaticomaxillary complex fractures with focus on surgical approaches and complications

Zygomaticomaxillary complex (ZMC) and orbital blow out fractures are commonly encountered midfacial fractures that may result in aesthetic and functional impairment. This retrospective study reports on the surgical treatment and associated postoperative complications in our patient collective. We evaluated 100 patients who underwent open reduction and internal fixation of midfacial fractures between 2010 and 2015. Preoperative clinical features, surgical technique and postoperative complications were analyzed. Surgery was performed with a mean latency of 7 days after trauma. We used titanium mesh and polydioxanone sheets to reconstruct the orbital floor. Most ZMC fractures were stabilized with two point fixation with titanium plates. Preoperative symptoms were present in 70 patients (70%). Infraorbital hypesthesia occurred in 49 patients, diplopia in 41 patients and ocular motility impairment in 24 patients. Postoperative symptoms persisted during a mean follow-up time of 4.5 months in 47 patients (47%) showing infraorbital hypesthesia in 24%, diplopia in 17%, ectropion in 7% and ocular motility impairment in 4%. Complications requiring revision were retrobulbar hematoma 3% (n = 3), ectropion 3% (n = 3), diplopia 1% (n = 1), exophthalmos 1% (n = 1), implant dislocation 1% (n = 1), implant discomfort 2% (n = 2), persisting fracture dislocation 1% (n = 1). All patients recovered without significant impairment. Surgery is required in the majority of the patients with midfacial fractures. Among others ectropion is challenging due to its aesthetic and functional impact on patients. To prevent ectropion, additional canthopexy or the transconjunctival surgical approach are reasonable options in selected cases. Level of Evidence: Level V, descriptive study.

A Comparative Analysis of Outcomes After Reduction of Zygomatic Fractures Using the Carroll-Girard T-bar Screw

PURPOSE

Several approaches are available for managing zygomatic fractures; however, each approach has its complications. Use of the Carroll-Girard T-bar screw (CGTS) can reduce complications because it reduces the number of approaches needed for reduction. This study aimed to analyze the efficiency of the CGTS compared with the 3-point approach.

METHODS

A retrospective study was conducted by reviewing the computed tomography scans of 204 patients who underwent reduction surgery of Knight and North type 3, 4, or 5 zygomatic fractures from March 2009 to August 2017. Facial asymmetry, operative time, and complications were evaluated to compare 2 groups of patients: those who underwent CGTS and those who did not. Bilateral differences in the distance from the reference plane to the malar eminence in 3 dimensions based on computed tomography scans were used to calculate facial asymmetry.

RESULTS

Among 204 patients, 91 were treated with CGTS whereas 113 patients underwent a 3-point approach. Bilateral differences in the position of the malar eminence and facial asymmetry were not statistically different in both groups. Operative time was not different in both groups. However, when patients with type 4 fracture were independently compared, the mean operative time was significantly shorter for the CGTS group. Wound dehiscence occurred in 11 patients (9.7%) in the 3-point approach group, compared with none in the CGTS group. None of the patients in the CGTS group complained of postoperative cheek scars over their incision sites.

CONCLUSIONS

This study revealed that CGTS is a useful and feasible instrument that can reduce the number of approaches for zygomatic bone reduction and help clinicians achieve satisfactory outcomes.

Introduction of pulsed radiofrequency cautery in infraorbital nerve block method for postoperative pain management of trauma-induced zygomaticomaxillary complex fracture reduction

Although various cases of neuralgia and its treatments have been reported, not enough evidence is present to recommend a single type of treatment as the most effective. The patient we have dealt with experienced significant interferences in his daily life due to chronic allodynia, but the symptom could not be resolved via previously reported treatments. We report a case of which a patient who presented infraorbital neuralgia after trauma was successfully treated by a novel treatment strategy. The patient was treated by applying infraorbital nerve block and pulsed radiofrequency cautery side by side. Through this report, we evaluate proper prevention and treatment strategies for patients who develop infraorbital neuralgia through similar etiologies.

[Possible surgical approaches to the orbit]

For removal of tumors and foreign bodies from the orbit, for treatment of severe inflammatory diseases, and for repositioning of bone fragments following fractures or during reconstruction of the bony orbit, several different surgical approaches are available. During the past decade, improved understanding of the pathology and pathophysiology of particular orbital diseases, advancements in clinical endoscopy and microscopy, the introduction of modern imaging techniques for preoperative visualization of pathologic findings, modern approaches to orbital reconstruction, as well as developments in adjuvant therapy have led to a reduction in invasiveness and development of the modern minimally invasive surgical approaches to the orbit usually used today. This review article aims to describe several surgical approaches to the orbit that are nowadays commonly applied-frequently in the context of interdisciplinary therapy-as well as their indications and potential complications. Particular attention is paid to minimally invasive approaches. These different surgical approaches allow a 360-degree exposure of the internal orbital structures with the optic nerve at the center ("round the clock access to the orbit"). The review is complemented by hints and tricks for particular approaches, as well as by a review of the latest literature in the field.

Clinical Application of Platelet-Rich Fibrin in Plastic and Reconstructive Surgery: A Systematic Review

BACKGROUND

Platelet-rich fibrin (PRF) has been applied in the clinical field for more than a decade, but largely in oral surgery and implant dentistry. Its utilization in plastic and reconstructive surgery is limited and lacking a comprehensive review. Hence, this article focuses on the various clinical applications of PRF pertaining to the plastic and reconstructive field through a systematic review.

METHODS

In this review, articles describing the clinical application of PRF in plastic and reconstructive surgery were screened using predetermined inclusion and exclusion criteria. The articles were summarized and divided into groups based on the utilization of PRF. The effects and complications of PRF were analyzed and concluded.

RESULTS

Among the 634 articles searched, 7 articles describing 151 cases are eligible. PRF was applied on 116 (76.8%) wounds to facilitate tissue healing, and the complete wound closure rate was 91.4% (106/116). Otherwise, PRF was applied in 10 (6.6%) cases of zygomaticomaxillary fracture to reconstruct orbital floor defects and in 25 (16.6%) cases of facial autologous fat grafts to increase the fat retention rate successfully. There is no report of PRF-related complications.

CONCLUSIONS

PRF could facilitate wound healing, including the healing of soft tissues and bony tissues, and facilitate fat survival rate. Further studies are needed to test the mechanism of PRF and expand its scope of application in plastic and reconstructive surgery.
