Abstract
ABSTRACT Orbital fractures account for up to 40% of craniofacial injuries. In this article, the authors present the transoral endoscopy-assisted plating technique for treating orbital blowout fractures (OBF). A retrospective analysis of 56 cases treated with transoral endoscopy-assisted approach was performed. Immediate versus delayed surgery decision-making was performed by using our 2-week algorithm. The surgical technique included only transoral incisions, forced duction and "pulse" tests, osteotomy, endoscopic inspections, the reduction with a curved elevator and an indwelling balloon, the retrieval of prolapsed fatty tissue back into the orbit, removal of sharp bony fragments, adaptation of the titanium mesh to the orbital floor and its fixation with screws to stable bony structures, reattachment of the osteotomized lateral wall, and postoperative computed tomography (CT) scan with 3D CT reconstruction. The overall success rate of surgeries was 96%. The resolution of comorbidities resulted in a normal globe position, normal eye movement, and the resolution of diplopia. Postoperative complications were insignificant with one case of surgical edema and one case of infection and sequestration that appeared six months after surgery. These results remained unchanged after 20 to 24 months of follow-up. The suggested minimally invasive transoral technique can be effectively implemented in cases of OBF as well as in cases when the medial wall of the orbit is involved. Our results presented a high success rate with minimal rate of complications, thus our technique is a safe way with minimal morbidity for treating OBF.

Abstract
Aim To assess the feasibility and the outcome of endoscopically assisted repair of zygomatico-maxillary complex orbital fractures in a tertiary care hospital. Materials and methods A descriptive study was carried out over a period of 2 years (01. 11. 2014-31. 10. 2016). 0°-4 mm endoscopes were used for intra-operative endoscopic exploration. Regular armamentarium for management of maxillofacial trauma along with standard plating systems was used. Commercially available medical grade titanium meshes were utilised for orbital floor reconstruction. Results Fifty-seven of hundred and twelve surgically managed zygomatico-maxillary complex fractures required orbital exploration. Twenty-one of these had reconstruction of the orbital floor. Endoscopically assisted exploration was performed in 10 of the 21; trans-nasally in three cases, the Caldwell-Luc approach was used in three cases, and in another three, the existing fracture in the anterior wall of the maxilla was utilised. In addition, an endoscopic trans-nasal-sphenoidal approach was opted for to access the orbital apex to manage fractured bone fragments that were impinging on the optic nerve in one of the patients. Conclusion Endoscopes serve as the primary tool in minimally invasive procedures. They are yet to evolve as a major role player in the maxillofacial arena. The authors conclude that endoscopes are truly beneficial as an adjunct to existing techniques. They hold much promise for the future.

Abstract
In the treatment of orbital defects, surgeon errors may lead to incorrect positioning of orbital implants and, consequently, poor clinical outcomes. Endoscopy can provide additional visualization of the orbit through the transantral approach. We aimed to evaluate whether endoscopic guidance during orbital reconstruction facilitates optimal implant placement and can serve as a convenient alternative for navigation and intra-operative imaging. Ten human cadaveric heads were subjected to thin-slice computed tomography (CT). Complex orbital fractures (Class III/IV) were created in all eligible orbits (n = 19), which were then reconstructed using the conventional transconjunctival approach with or without endoscopic guidance. The ideal implant location was digitally determined using pre-operative CT images, and the accuracy of implant placement was evaluated by comparing the planned implant location with the postoperative location. There were no statistically significant differences (p > 0.05) in the degree of implant dislocation (translation and rotation) between the transconjunctival orbital reconstruction and the endoscopic-assisted orbital reconstruction groups. Endoscopic-assisted orbital reconstruction may facilitate the visualization of orbital defects and is particularly useful for training purposes; however, it offers no additional benefits in terms of accurate implant positioning during the anatomical reconstruction of complex orbital defects.

Abstract
Minimally invasive surgical techniques, particularly endoscopic techniques, have revolutionized otolaryngeal surgery. Endoscopic techniques have been gradually applied in orbital surgery through the sinus inferomedial to the orbit and the orbital subperiosteal space. Endoscopic techniques help surgeons observe fractures and soft tissue of the posterior orbit to precisely place implants and protect vital structures through accurate, safe, and minimally invasive approaches. We reviewed the development of endoscopic techniques, the composition of endoscopic systems for orbital surgery, and the problems and developmental prospects of endoscopic techniques for simple orbital wall fracture repair.

Abstract
BACKGROUND The treatment of complex orbital floor fractures with extensive orbital prolapse remains a surgical challenge in craniomaxillofacial traumatology and is still controversially discussed. Reduction of orbital tissue via a transcutaneous or transconjunctival approach alone can be very difficult and lead to unsatisfying results. METHODS Over a 3-year-period, we enrolled 13 patients who underwent endoscopy-assisted reconstruction of isolated orbital floor fractures via a combined subciliary and transantral approach. Patient data, imaging and ophthalmologic examination were reviewed prospectively. RESULTS Ten patients underwent primary surgical treatment, 3 patients had secondary surgical treatment because of unsatisfactory results of primary surgical intervention. All patients had an uneventful postoperative course without ophthalmologic deterioration, no further surgical procedures were necessary. CONCLUSIONS The additional use of an endoscopy-assisted transantral approach provides a reliable treatment modality in selected cases. To our knowledge, this is the only study of patients treated with a combined subciliary and transantral approach. Special emphasis was given to postoperative functional results, a short algorithm for use of an additional transantral endoscopy-assisted approach is presented.

Abstract
OBJECTIVE In this surgical-anatomical cadaveric study we investigate the feasibility of the transmaxillary endoscopic approach to the intraorbital space. Anatomical landmarks are defined, the endoscopic view in the orbital space is studied and complications that can occur are discussed. METHODS Nine formalin-fixed heads were used to study the transmaxillary endoscopic approach to the orbit. The approach was used twice on each head (once for each maxilla). Therefore, we report our results on 18 transmaxillary intraorbital approaches. For better differentiation of anatomical structures, the veins and arteries were injected with blue and red plastic respectively in six cadaveric heads. RESULTS The transmaxillary approach enables viewing the inferior intraconal structures without endangering the infraorbital nerve and its artery and without diversion of the inferior rectus muscle. The optic nerve was visualised more easily through the approach medial to the inferior rectus muscle instead of lateral to the muscle since the ciliary nerves are in the way in the lateral approach. The combination of the approaches medial and lateral to the inferior rectus muscle allows very good identification of all important anatomical structures in the inferior intraconal space. CONCLUSION The transmaxillary endoscopic approach to the orbit is a useful new approach in the surgical armamentarium for orbital lesions. The overview of the inferior part of the orbit is excellent, and the lateral part of the optic nerve can be visualised. Careful anatomical dissection allows visualisation of important anatomical structures in the orbit without damaging nerves or arteries.

Transzygomatic Kirschner wire fixation for the treatment of blowout fracture. J Plast Reconstr Aesthet Surg 2012; 65:875-82.

Abstract
BACKGROUND Total orbital floor reconstruction with sheet-shape materials is available for the treatment of extensive and crushed-type blowout fractures. Simple blowout fractures, on the other hand, require only manual reduction without fixation. Although several types of blowout fractures do not require total reconstruction, some fixation is usually necessary. METHODS Eighteen cases of blowout fracture were treated with transzygomatic Kirschner wire fixation between 2002 and 2009. This technique was applied to simple fracture cases in which periorbital soft tissue re-herniated through the floor defect into the maxillary sinus after manual reduction, despite improvement of the extra-ocular muscle entrapment. The wire was used to directly support the fracture segment in five cases and used together with a maxillary sinus anterior wall bone graft in 13 cases. RESULTS Mean follow-up was 12.5 months. Mild diplopia remained as a subjective symptom in one case. None of the cases developed major complications or conspicuous scars on the cheek. CONCLUSIONS Transzygomatic Kirschner wire fixation for blowout fracture has the advantages of precise and rigid fixation of all parts of the inferior floor, minimal morbidity without requiring an orbital approach and long-term safety without artificial remnants. This technique can be applied for the treatment of simple blowout fractures.

Abstract
Objective. To prospectively evaluate the safety, effectiveness, and utility of orbital and transorbital endoscopic surgery. Study Design. Case series with planned data collection. Setting. Level 1 trauma center and tertiary academic hospital. Subjects and Methods. Consecutive sample of 107 patients undergoing orbital or transorbital endoscopic operations. Main Outcome Measures. Ability to achieve intraoperative goals using endoscopic approach; occurrence of predetermined intraoperative or postoperative complications. Results. One hundred seven patients (aged 6-83 years) underwent orbital or transorbital endoscopic surgery for 6 different indications. Seven incisions were used. Endoscopic orbitotomies were made through all 4 orbital walls to access surrounding structures. Intraoperative goals were achieved endoscopically in 106 patients. Mean follow-up was 3 months (mean ± SD, 3.0 ± 3.5). No complication was directly related to surgical approach or use of endoscopy. Seventeen complications were detected in 2 categories: persistent diplopia and persistent vision change. No patient had vision loss. No nonfracture patient suffered a complication. Subgroup analysis demonstrated no difference in surgical success rates when compared with transnasal and transantral medial orbital wall and orbital floor repair and cerebrospinal fluid leak repair. Endoscopic visualization was advantageous in several respects: superior visualization and lighting, particularly posterior to the equator of the globe; image magnification; and video monitoring for education and operating room staff involvement. It also facilitated surgical navigation and computer-aided reconstruction. Conclusion. Orbital and transorbital endoscopy are versatile, effective, and safe approaches useful for addressing diverse urgent and elective problems. In appropriate clinical situations, these procedures may offer better access and visualization than open or transnasal approaches.

Abstract
Endoscopic approaches to maxillofacial trauma have included their use in temporomandibular joint arthroscopy, zygomatic arch repair, repair after orbital trauma, repair of frontal sinus fractures, and finally in the repair of subcondylar mandibular fractures. These techniques provide exciting new options for the management of facial fractures. Many of the techniques provide a steep learning curve and require specialized equipment. The approach to an orbital blowout fracture allows the use of a Caldwell-Luc approach and the use of a naturally occurring body space (the maxillary sinus) for the visualization and maneuvering of the endoscope, tools, and implants. The use of the endoscope in the management of fractures for facial structures such as mandibular subcondylar fractures, which do not have a naturally occurring body cavity, may present greater challenges when trying to obtain visualization, reduction, and fixation. When used for the treatment of subcondylar fractures, wide exposure and the use of right-angled drills and screw drivers may significantly help with this procedure. This may be considered by some surgeons as an endoscopically "assisted" procedure that can possibly be accomplished with direct visualization and the use of dental mirrors. It remains to be seen as to whether some of these diverse endoscopic applications will represent the standard of care in the future or remain a specialized technique practiced by a minority of surgeons in a few specialized centers. This article reviews various endoscopic applications to maxillofacial trauma and discusses some of the controversies of these techniques.

Abstract
PURPOSE OF REVIEW Many of the successes and controversies in endoscopic management of craniofacial trauma are exemplified in the management of frontal sinus trauma. RECENT FINDINGS The effort to reduce surgical morbidity and to optimize reconstruction of craniomaxillofacial injuries has resulted in the development of less invasive surgical approaches and in the use of computer image guidance in surgical planning and execution. Minimally invasive management of frontal sinus inflammatory disease has gained wide acceptance. The technology and techniques applied to surgery of the floor of the frontal sinus is now being applied to the management of frontal sinus trauma. A paradigm shift in the treatment of frontal sinus trauma may be underway. SUMMARY An increasing scope of less severe injuries is being managed expectantly with endoscopic frontal sinus surgery available for salvage. There may be an overall decrease in the most severe frontal sinus injuries owing to enforcement of seatbelt and airbag usage. And the most severe injuries are often best managed through cranialization with anterior skull base reconstruction. Thus, the role for frontal sinus obliteration purely to obviate fractures of the frontal sinus outflow tract may be vanishing.
