Abstract
To clinically and radiographically evaluate patient-specific titanium meshes via a trans-antral approach for correction of enophthalmos and orbital volume in patients with recent unilateral orbital floor fracture. Seven patients with unilateral orbital floor fractures received patient-specific titanium meshes that were designed based on a mirror-image of the contralateral intact orbit. The patient-specific implants (PSIs) were inserted via a trans-antral approach without endoscopic assistance. The patients were evaluated clinically for signs of diplopia and restricted gaze as well as radiographically for enophthalmos and orbital volume correction. Diplopia was totally resolved in two of the three patients who reported diplopia in the upward gaze. Whereas enophthalmos significantly improved in all but two patients, with a mean value of 0.2229 mm postoperatively compared to 0.9914 mm preoperatively. CT scans showed excellent adaptation of the PSIs to the orbital floor with a mean reduction of the orbital volume from 29.59 cc to 27.21 cc, a mean of 0.6% smaller than the intact orbit. It can be concluded that the proposed PSI can offer good reconstruction of the orbital floor through an isolated intraoral transantral approach with minimal complications. It could of special benefit in extensive orbital floor fractures.

Abstract
Orbital fractures constitute a significant percentage of all midface injuries. Here, we present a contemporary evidence-based review of the major surgical approaches for orbital wall fractures and analyze the literature to compare all major surgical procedures and their complication rates. Method A systematic review was conducted to compare surgical approaches (subciliary, transcaruncular, transconjunctival, subtarsal, and endoscopic) and postoperative complications in patients who underwent surgical fixation of orbital wall fractures. A database search in PubMed (PubMed Central, MEDLINE and Bookshelf) was performed for all articles containing the terms "orbital," "wall," "fracture," and "surgery" with different combinations. Results A total of 950 articles were obtained and 25 articles were included, representing an analysis of 1137 fractures. The most frequent surgical approach was the endoscopic (33.3%) followed by the external surgical approaches, specifically transconjunctival (32.8%), subciliary (13.5%), subtarsal (11.5%), and transcaruncular (8.9%). The transconjunctival approach had a statistically significantly higher rate of complications (36.19%), followed by the subciliary (21.4%), and endoscopic approach (20.2%, P < 0.0001). The subtarsal approach had a statistically significantly lower rate of complications (8.2%) followed by the transcaruncular approach (14.0%, P < 0.0001). Conclusion The subtarsal and transcaruncular approaches were observed to have the lowest rates of complications, whereas the transconjunctival, subciliary, and endoscopic approaches were reported to have higher rates of complications.

Surgical repair of large orbital floor and medial wall fractures with destruction of the inferomedial strut: Initial experience with a combined endoscopy navigation technique. J Plast Reconstr Aesthet Surg 2023; 77:104-110. [PMID: 36563635 DOI: 10.1016/j.bjps.2022.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2021] [Revised: 08/24/2022] [Accepted: 11/15/2022] [Indexed: 11/21/2022]
Abstract
The application of navigation and endoscope is an area of intense interest in the surgical repair of orbital fractures. This study explored the advantages of a combined endoscopy navigation technique (ENT) for repairing large orbital floor and medial wall fractures (OFMWFs) with destruction of the inferomedial strut (IMS). Fifty-two consecutive patients with large OFMWFs with the destruction of the IMS underwent ENT-assisted surgical repair from January 2013 to February 2016. Patient demographics, causes of injury, clinical features, imaging data, and follow-up information (diplopia, ocular dysmotility, enophthalmos, infraorbital hypoesthesia, and other conditions) were collected and analyzed. Orbital volumes and implant positions were also evaluated. The median follow-up duration was 21 (range, 16-29) months. At the end of the follow-up visits, orbital reconstruction was demonstrated by orbital computed tomography. Of the 30 patients with diplopia within the 30-degree visual field of gaze, 27 (90%) reached diplopia remission. Of 40 patients, 34 (85%) achieved complete elimination of ocular dysmotility. Of 47 patients with enophthalmos of >2 mm, 43 (91%) acquired good symmetry with a mean improvement of 3.00 ± 1.00 mm. Of 33 patients, 27 (82%) recovered from infraorbital hypoesthesia. The postoperative orbital volumes of the two sides showed no significant differences (p = 0.087, paired t-test). Early surgical repair showed better outcomes of diplopia, ocular motility, and enophthalmos than late repair (p = 0.001, p = 0.007, and p = 0.000, generalized estimated equations). No patient developed surgery-related complications of visual acuity compromise, strabismus, ectropion, entropion, or lacrimal canaliculus injuries. ENT-assisted surgery appears to be safe, precise, and effective for the repair of large OFMWFs with destruction of the IMS.

Abstract
Substantial controversy exists regarding the timing of intervention and management of patients with orbital floor fractures. Recent advances in computer-aided technology, including the use of 3-dimensional printing, intraoperative navigational imaging, and the use of novel implants, have allowed for improvement in prospective management modalities. As such, this article aims to review the indications and timing of repair, surgical approaches, materials used for repair, and contemporary adjuncts to repair. Indications for orbital floor fracture repair remain controversial as many of these fractures heal without intervention or adverse sequelae. Intraoperative navigation and imaging, as well as endoscopic guidance, can improve visualization of defects mitigating implant positioning errors, thereby reducing the need for secondary corrective procedures. Patient-specific implants may be constructed to fit the individual patient's anatomy using the preoperative CT dataset and mirroring the contralateral unaffected side and have been shown to improve pre-operative efficiency and minimize postoperative complications. With increased data, we can hope to form evidence-based indications for using particular biomaterials and the criteria for orbital defect characteristics, which may be best addressed by a specific surgical approach.

Abstract
Posttraumatic enophthalmos (PE) arises when the ocular globe is displaced posteriorly and inferiorly in the orbital cavity due to a mismatch in orbital volume and orbital content. This most commonly happens after orbital fractures. The resulting disruptions to aesthetic form and ocular functions often necessitate surgical correction for reconstruction and restoration. The purpose of surgical management of PE is to reconstruct orbital shape and volume as well as to restore any herniated orbital content. This can be particularly challenging in cases involving large defects that require complex orbital reconstruction. Recent advancements in computer-aided surgery have introduced innovative and important tools to assist surgeons with these difficult cases. The ability to create customized, patient-specific implants can facilitate reconstruction involving complicated anatomy. Additionally, intraoperative imaging and intraoperative navigation can serve as useful guides for surgeons to more accurately place implants, especially in cases with limited visualization, in order to achieve optimal outcomes.

Abstract
ABSTRACT The purpose of this article is to introduce simple, minimally invasive, more effective, and more comfortable method using a customized balloon with contrast agent for orbital floor fracture. The customized balloon was fabricated to compensate for its shortcomings, based on the experiences from four patients who underwent the surgery of orbital floor fracture using a Foley catheter.In a 33-year-old female patient with only orbital floor fracture, the reduction was performed using a transmaxillary approach with a customized balloon. The customized balloon was made using latex glove and 6 French gavage tube, and the contrast agent was injected within the balloon. A micro saw was used to form a window on the anterior wall of the maxillary sinus. Compared to the round bur, a micro saw can create an internal bevel along with minimal bone removal, which makes it possible to insert the bone fragment tightly without falling into the maxillary sinus when the fragment is repositioned. The use of contrast agent makes it more visible to determine the position of the balloon instantly during surgery by take portable radiograph. The balloon has removed after 3 weeks and no diplopia or no enophthalmos was observed. There remained very small defect on the anterior sinus wall about the size of gavage tube.The transmaxillary approach, along with a conjunctival or subciliary approach, can be a good choice for the treatment of orbital fractures. Compared to the conventional Foley catheter, the application of a customized balloon and contrast agent supports the entire orbital floor evenly and wide, and fills the maxillary sinus without an empty space. It is easy to check the location of the balloon through x-ray photography during surgery, and has a very little discomfort for the patient.

Abstract
BACKGROUND AND PURPOSE Extensive orbital floor and medial wall fractures compared with isolated orbital wall fractures are more likely to require surgical correction because of a higher possibility of complications like diplopia, enophthalmos, or numbness. The unique and complex contours of the orbital anatomy limit the intraoperative view of the intraorbital anatomy, and complex orbital fractures involving the buttress of the transition zone area all make orbital reconstruction surgery more challenging. The aim of this study was to describe our experience with surgical approaches using navigation- and endoscope-assisted guidance for extensive orbital floor and medial wall fracture reconstruction. PATIENTS AND METHODS A retrospective study was conducted on consecutive 17 patients from 2015 to 2017 presenting with unilateral extensive orbital floor and medial wall fractures at the Chang Gung Memorial Hospital, Linkou Branch. The fractures were treated surgically with a preformed mesh plate and layered Medpor (Porex Surgical Inc, Atlanta, Ga) through navigation and endoscopy. The preoperative and postoperative functional and aesthetic outcomes were described. RESULTS All extensive orbital floor and medial wall fractures were successfully reconstructed. Of the 17 patients, 11 experienced diplopia preoperatively, and for 2 of the 11 patients, diplopia improved immediately after surgery. In the remaining 9 patients, diplopia still persisted after surgery; however, diplopia recovered after an average of 3.44 months (range, 1-9 months). Average enophthalmos among the 10 patients, evaluated by postoperative follow-up computed tomography scan, improved from 2.99 to 0.68 mm. There were no major complications during follow-up, and all patients were satisfied with their final appearance and function. CONCLUSIONS On the basis of the results, our surgical approach using preformed titanium mesh plates and Medpor under the assistance of navigation and endoscopy can be a safe, accurate, and effective method for the management of extensive orbital floor and medial wall fractures and clearly optimizes functional and aesthetic outcomes.

Abstract
BACKGROUND Sequelae of inadequate orbital reconstruction include enophthalmos, hypoglobus, and diplopia. Accuracy of orbital reconstruction is largely subjective and especially difficult to achieve because of anatomic distortion in secondary or late reconstruction and in extensive injury. We combined computer navigation and endoscopy to perform accurate, aesthetic, and safe minimal-access primary and secondary orbital reconstruction. METHODS From 2013 to 2014, 24 patients underwent unilateral primary and secondary or late minimally invasive orbital reconstruction with mainly Medpor and/or titanium mesh by navigation and endoscopic assistance through transantral, transconjunctival, or upper blepharoplasty approaches. Mean follow-up was 13.8 months (range, 6.2 months to 2.8 years). RESULTS All orbital fractures were successfully reduced. Average enophthalmos among patients who underwent early reconstruction, late reconstruction, and multiorbital wall repair improved (p < .001) to 0.2 mm from 1.6, 2.6, and 2.6 mm, respectively. Hypoglobus and diplopia resolved in all. In early reconstruction patients, mean interorbital volume difference improved from 1.72 ± 0.87 to 0.53 ± 0.83 ml (P = .03). For late reconstruction patients, this difference improved from 3.41 ± 1.23 to 0.56 ± 0.96 ml (p < .001). There were no major complications during follow-up, and all were satisfied with their final appearance and function. CONCLUSION Navigation sharpens reconstructive accuracy and avoids injury to vital structures. Combined with endoscopic assistance for minimal-access reconstruction of wide-ranging orbital defects from primary to secondary or late cases and to extensive multiwall fractures, navigation facilitates minimal cosmetic incision and synergistic endoscope use and clearly optimizes aesthetic and functional outcomes, all with enhanced safety and unparalleled intraoperative visualization.

Abstract
OBJECTIVES: This study evaluates the usefulness of endoscopic repair compared to external repair in the treatment of blowout fracture (BOF) of the orbit. STUDY DESIGN AND SETTING: This retrospective study comprised 100 patients who had had surgical repair of orbital BOF since 1992. Forty-eight of the 100 had undergone endoscopic repair, 48 patients had had external repair, and four patients underwent surgery that combined the two approaches. The two basic approaches were evaluated and compared with respect to technique, results and complications. RESULTS: Endoscopically, transnasal and transantral approaches had been used for reduction and support of fractured medial and inferior walls, respectively. In the external approach, various transorbital incisions were made and the fractured wall was repaired with alloplastic or autologous materials. Complete or partial resolution of preoperative diplopia was achieved in 94% of the endoscopic group and 83% of the external group (NS). Enophthalmos was improved in 89% of the endoscopic group and 76% of the external group (NS). Though the endoscopic group had no significant complications, the external group had ectropions, significant facial scars, extrusion of inserted Medpor, and intra-orbital hematoma. CONCLUSIONS: Endoscopic repair appears to be a safe and effective technique for the treatment of BOF of the orbit. © 2007 American Academy of Otolaryngology–Head and Neck Surgery Foundation.

Abstract
OBJECTIVES: Transconjunctival and subciliary approaches to orbital floor blowout fractures (OBF) have known risks of postoperative eyelid malposition. This study evaluates the endoscopic transmaxillary repair of OBFs in a cadaveric model and clinical setting. METHODS: Sixteen cadaveric and 10 clinical OBFs were repaired endoscopically. A Caldwell-Luc approach and modified sinus surgery instrumentation were used to repair each fracture. Variations in fracture pattern, instrumentation, and surgical technique were evaluated. RESULTS: Endoscopic repair was achieved in all 16 cadaveric orbits and in 9 of 10 patients. Fracture patterns were classified as either medial or lateral to the infraorbital nerve. Average clinical operating time was 1:38. Of 9 postoperative CT scans, 5 were rated as excellent, 3 as good, and 1 as poor. CONCLUSIONS: The endoscopic transmaxillary approach is a safe, viable technique for OBF repair. It offers improved visualization, anatomic fracture repair, no risk of postoperative eyelid complications, and good clinical results. EBM rating: C.

Abstract
Here we report a patient with a blow-out fracture of the orbital floor that was treated by an intraoral transmaxillary approach. This 38-year-old man suffered a sudden blow to the periorbital area, which caused prolapse of the orbital contents into the maxillary sinus. The modified Caldwell-Luc approach was used to repair the orbital blow-out fracture and the maxillary sinus during was packed with Frazin gauze for 7 days to prevent recurrence of the prolapse. This was an easy and minimally invasive technique for the management of a blow-out fracture of the orbital floor.

Abstract
In the last decades, the introduction of computed tomography has allowed an increase in the number of diagnosed fractures of the medial orbital wall. To repair medial wall fractures, many surgical techniques have been proposed (1), each one with its advantages and disadvantages. In this study, we compared endoscopic endonasal and transcutaneous reduction approaches in terms of surgery time and clinical outcome. Between 2001 and 2005, 81 patients with orbital wall fractures were treated at our department. Among these 81 patients, 24 (29.63%) were affected by a medial orbital fracture. Patients with fracture to both floor and medial walls underwent floor reduction by a transcutaneous subpalpebral approach (n = 9, 11.1%), whereas patients with isolated medial wall fracture underwent medial wall reduction by a transcutaneous subpalpebral approach using alloplastic implants (n = 8, 9.88%) or were treated by endoscopic approach (n = 5, 6.17%). After surgery, oculomotor function improved in all 22 patients. None of the patients had complications. Computed tomography revealed a well-consolidated site of fracture in both endoscopic endonasal and transcutaneous approaches. The average operating time for endoscopic endonasal and transfacial approach was 50 and 45 minutes, respectively. In this paper, the author proposed a results comparison between the endoscopic approach and the transcutaneous one.

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.

Infraorbital nerve block for isolated orbital floor fractures repair: review of 135 consecutive cases. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2014; 2:e97. [PMID: 25289294 PMCID: PMC4174218 DOI: 10.1097/gox.0000000000000039] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2013] [Accepted: 11/27/2013] [Indexed: 10/25/2022]
Abstract
BACKGROUND Orbital blowout fractures can be managed by several surgical specialties including plastic and maxillofacial surgery, otolaryngology, and ophthalmology. Recommendations for surgical fracture repair depend on a combination of clinical and imaging studies to evaluate muscle/nerve entrapment and periorbital tissue herniation. METHODS The aim of this study was to verify the applicability of regional anesthesia when repairing orbital floor fractures. A retrospective chart review was performed for isolated orbital floor fractures treated at the Department of Maxillofacial Surgery in Florence between May 2011 and July 2012. The study included 135 patients who met the inclusion criteria: 96 subjects were male (71%) and 39 were female (29%). The mean age was 45.3 years, ranging from 16 to 77 years. RESULTS The results revealed that isolated anterior orbital floor fractures can be safely repaired under regional and local anesthesia. Regional and local anesthesia should be combined with intravenous sedation when the fracture involves the posterior floor. The surgical outcome was comparable to the outcome achieved under general anesthesia. There was a lower rate of surgical revisions due to concealed malposition or entrapment of the inferior rectus muscle (19% vs 22%). However, this result was not statistically significant (P > 0.05). CONCLUSIONS THERE ARE SEVERAL ADVANTAGES TO SURGICALLY REPAIRING ISOLATED ORBITAL FLOOR FRACTURES UNDER REGIONAL AND LOCAL ANESTHESIA THAT INCLUDE THE FOLLOWING: surgeons can check the surgical outcome (enophthalmos and extrinsic ocular muscles function) intraoperatively, thereby reducing the reoperation rate; patient discomfort due to general anesthesia is eliminated; and the hospital stay is reduced, thus decreasing overall healthcare costs.

Abstract
Although endoscopic transmaxillary repair of orbital floor fractures is a minimally invasive treatment, controversy remains regarding the method for supporting the orbital floor after elevation of the orbital contents. To date, a urethral balloon catheter has been widely used. However, it can be difficult to leave the catheter in place for a long time period due to the inconvenience, and prolapse of the orbital contents may recur in the case of its premature removal. This study described the techniques for endoscopic reduction and use of a balloon for orbital floor fractures. From June 2006 through November 2011, 30 of 52 patients (57.7%) with an isolated orbital floor fracture underwent endoscopic transmaxillary repair. A maxillary sinus balloon (#3007, Koken Co., Japan) was inserted into the maxillary sinus to support the orbital floor after endoscopic transmaxillary reduction, and the connecting tube of the balloon was pulled into the nasal cavity through the maxillary ostium. After confirmation of accurate reduction by postoperative CT, the connecting tube was shortened and hidden in the nasal cavity. The balloon was left in place for 4-8 weeks, and then removed via the maxillary ostium on an outpatient basis. Complete resolution of the preoperative diplopia was achieved in 93%, and no late-developing enophthalmos was seen in 97% of the patients. There were no significant complications. This technique is safe and permits prolonged retention of the balloon, without interfering with daily life.

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
It is wise to recall the dictum "children are not small adults" when managing pediatric orbital fractures. In a child, the craniofacial skeleton undergoes significant changes in size, shape, and proportion as it grows into maturity. Accordingly, the craniomaxillofacial surgeon must select an appropriate treatment strategy that considers both the nature of the injury and the child's stage of growth. The following review will discuss the management of pediatric orbital fractures, with an emphasis on clinically oriented anatomy and development.

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.

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
PURPOSE OF REVIEW Orbital trauma is common and frequently complicated by ocular injuries. The recent literature on orbital fracture is analyzed with emphasis on epidemiological data assessment, surgical timing, method of approach and reconstruction materials. RECENT FINDINGS Computed tomographic (CT) scan has become a routine evaluation tool for orbital trauma, and mobile CT can be applied intraoperatively if necessary. Concomitant serious ocular injury should be carefully evaluated preoperatively. Patients presenting with nonresolving oculocardiac reflex, 'white-eyed' blowout fracture, or diplopia with a positive forced duction test and CT evidence of orbital tissue entrapment require early surgical repair. Otherwise, enophthalmos can be corrected by late surgery with a similar outcome to early surgery. The use of an endoscope-assisted approach for orbital reconstruction continues to grow, offering an alternative method. Advances in alloplastic materials have improved surgical outcome and shortened operating time. SUMMARY In this review of modern orbital reconstruction, several controversial issues such as surgical indication, surgical timing, method of approach and choice of reconstruction material are discussed. Preoperative fine-cut CT image and thorough ophthalmologic examination are key elements to determine surgical indications. The choice of surgical approach and reconstruction materials much depends on the surgeon's experience and the reconstruction area. Prefabricated alloplastic implants together with image software and stereolithographic models are significant advances that help to more accurately reconstruct the traumatized orbit. The recent evolution of orbit reconstruction improves functional and aesthetic results and minimizes surgical complications.

Abstract
Functional Endoscopic Sinus Surgery (FESS) is a highly sophisticated type of surgery, which has revolutionized the surgical management of chronic sinus diseases. In the ophthalmic field, FESS plays a crucial role in the management of a few conditions, but not without risks. Ophthalmic complications associated with FESS are well documented. They mainly occur due to the shared common anatomic areas between ophthalmology and otolaryngology. Ophthalmic complications can vary in severity from very trivial cases such as localized hematoma collection, which is not very problematic to very devastating cases, such as optic nerve damage, which can lead to complete blindness. In order to minimize such complications, safety measures need to be considered prio to the surgery, these include; precise knowledge of detailed anatomy, the operating surgeon's ability to interpret precisely the para nasal sinus CT scan and experienced procedural surgical skills.

Abstract
PURPOSE Infraorbital blow-out fracture (IOBF) is an uncommon midfacial trauma, and impairs eyeball function and causes esthetic problems. The extraoral approach can lead to some complications such as scarring, ectropion, and entropion. The intraoral approach, such as a transantral approach, has advantages such as no visible scaring, it can be used to simultaneously treat a zygomaticomaxillary complex fracture (ZMCF), and the procedure is relatively easy. PATIENTS AND METHODS IOBFs were reduced from the maxillary sinus, and fixated internally using miniplates and screws with/without Medpor (Porex, Newnan, GA) via a transantral approach. We used this technique in 11 patients who had an inferior blow-out fracture. Patient's records and CT scans were reviewed. RESULTS The mean age of the patients was 37 years (ranging between 15 years and 68 years). The mean follow-up period was 9.8 months, which ranged from 1 to 24 months. Before the operation, the patients had orbital symptoms: diplopia in 3 patients; enophthalmos in 4; and gaze limitation in 3. All the patients showed periorbital swelling and ecchymosis. After surgery, none of the patients had diplopia, gaze limitations, and enophthalmos. There were no orbital symptoms or sinus symptoms due to an infection or allergic reaction after surgery except in 1 patient. In 1 patient, maxillary sinusitis developed at 4 months after surgery which subsided with antibiotic therapy after plate removal. CONCLUSION We think this technique offers an easy approach, and produces reliable, satisfactory results in IOBF.

Abstract
We conducted a cadaver study to determine the ease of use and functionality of a flexible endoscope holder in the visualization and repair of orbital floor fractures via a transantral approach. Four fresh cadaver heads were dissected through a sublabial antrotomy incision with a 30° endoscope attached to a flexible holder. An implant was placed to restore the normal anatomy. With the use of this exclusive endoscopic approach, all orbital floor fractures were identified in their entirety and completely reduced with alloplastic material. We conclude that the flexible endoscope holder provides clearer visualization, greater instrument mobility, and an overall superior dissection and placement of implants in the endoscopic repair of orbital floor fractures.

Abstract
PURPOSE OF REVIEW Endoscopic applications in otolaryngology continue to expand, most recently in the area of maxillofacial trauma. Endoscopic management of orbital blow-out, frontal sinus, zygomatic arch, and subcondylar fractures has been described. This paper reviews the current literature including new techniques, indications, and outcomes in endoscopic management of facial fractures. RECENT FINDINGS Very few large studies of endoscopic fracture repair exist. The current literature, however, suggests that, when compared with an open approach, smaller endoscopic incisions result in reduced patient morbidity with similar outcomes. Dedicated endoscopic instrumentation and novel surgical approaches continue to be developed. SUMMARY Endoscopic repair of facial fractures is a new and evolving technique that offers the potential for reduced patient morbidity and operating time, as well as quicker patient recovery. Current applications include the management of orbital blow-out, frontal sinus, zygomatic arch, and subcondylar fractures. It should be emphasized that endoscopy augments, rather than replaces, the 'time tested' principles of adequate skeletal exposure, accurate fracture reduction, and appropriate internal fixation.

Abstract
Enophthalmos is a relatively frequent and misdiagnosed clinical sign in orbital diseases. The knowledge of the different etiologies of enophthalmos and its adequate management are important, because in some cases, it could be the first sign revealing a life-threatening disease. This article provides a comprehensive review of the pathophysiology, evaluation, and management of enophthalmos. The main etiologies, such as trauma, chronic maxillary atelectasis (silent sinus syndrome), breast cancer metastasis, and orbital varix, will be discussed. Its objective is to enable the reader to recognize, assess, and treat the spectrum of disorders causing enophthalmos.

Fernandes R, Fattahi T, Steinberg B, Schare H. Endoscopic Repair of Isolated Orbital Floor Fracture With Implant Placement. J Oral Maxillofac Surg 2007; 65:1449-53. [PMID: 17656267 DOI: 10.1016/j.joms.2006.10.080] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2006] [Revised: 05/21/2006] [Accepted: 10/06/2006] [Indexed: 11/28/2022]
Abstract
PURPOSE This study was designed to assess the use of the endoscopic transmaxillary approach to correcting orbital blowout fractures (OBFs) with placement of alloplastic implants. MATERIALS AND METHODS This was a prospective study of patients treated in the Division of Oral and Maxillofacial Surgery, University of Florida College of Medicine, Jacksonville over a 6-month period, July to December 2005. Ten patients (7 males, 3 females, age range 19 to 47 years [average age 37.3 years]) met the inclusion criteria for the study and consented to undergo surgical repair. The injury was most commonly secondary to assault (6 cases); the remainder were secondary to motor vehicle collisions. The time from injury to correction ranged from 3 to 36 days (average, 10.9 days). A computed tomography scan with axial and coronal views was obtained in each patient at the time of presentation. All patients who met the inclusion criteria for the study underwent an endoscopic-assisted transmaxillary repair of their OBF with placement of a Medpor implant (Porex Surgical Products, Newnan, GA). RESULTS Of the 10 patients, 9 presented with diplopia preoperatively and 4 had associated entrapment on upward gaze. One patient did not have entrapment or diplopia but had a fracture larger than 2 cm(2). All patients underwent successful OBF repair with placement of a Medpore implant through the endoscopic transmaxillary approach, and all experienced resolution of preoperative diplopia and/or entrapment. None of the patients developed enophthalmos at a mean follow-up of 12.7 weeks. CONCLUSIONS The endoscopic transmaxillary approach to correcting OBF is an excellent alternative to the transconjunctival approach. This approach carries a very low morbidity and may be used in circumstances in which conventional approaches are not feasible.

Abstract
The effective management of mandibular cysts and tumours relies on obtaining an accurate tissue diagnosis with the acquisition of specimens representative of the lining and/or contents of the lesion. Access to such abnormalities is not commonly an issue since bony windows can be made in readily accessible areas. However, less accessible regions such as the ascending ramus, coronoid process and condyle can be surgically challenging without an extensive lateral approach. This paper reports a minimally-invasive technique in which an endoscope was used to facilitate the core biopsy of a condylar lesion.

Abstract
Significant orbital trauma can result in orbital floor fractures with subsequent prolapse of the orbital contents into the paranasal sinuses. Prolapse of the periorbita can result in extraocular muscle entrapment, diplopia, enophthalmos, and even visual loss. Management of orbital floor fractures traditionally has been accomplished through transconjunctival and subciliary incisions. These approaches provide adequate visualization and cosmetically acceptable scars. Unfortunately, post-operative lid malposition can occur in a small percentage of cases. Another limitation is easy visibility of the posterior orbit, which often is obscured by prolapsed orbital fat. In light of these limitations, some surgeons have begun to evaluate an endoscopic approach to orbital floor fractures. The endoscopic approach offers a hidden incision, improved fracture visualization, and avoidance of post-operative eyelid malposition. This article reviews the indications, technique, and potential complications of endoscopic orbital blow-out fracture repair.

Abstract
Orbital fractures involving the middle or posterior third of the orbital floor are difficult to visualize with traditional surgical approaches. The authors describe their method of combining a transconjunctival incision with an endonasal endoscopic approach in the repair of orbital fractures. In their experience, this technique is especially useful in the treatment of posterior fractures or secondary repairs for residual enophthalmos. Besides better visualization, advantages include increased illumination; video projection for the rest of the surgical team and for documentation and recording; confirmation of correct implant placement; and, most importantly, precise and complete reduction of herniated orbital soft tissues.

Abstract
Otolaryngology and ophthalmology have a long and congenial professional relationship in the development of their mutual specialties over many years. In the early years they were one professional society, but later split into their separate specialties. Some problems involve both specialties because of the shared common anatomic areas. These problems include: orbital complications of sinusitis, management of exopthalmus, silent sinus syndrome, lacrimal apparatus problems, tumor and trauma problems, optic nerve decompression, and complications of endoscopic sinus surgery. Both specialties have their own expertise to contribute to these common problems. In many cases it is in the best interest of the patient if both specialties consult and contribute their knowledge, experience, and techniques in these cases. Otolaryngologists and opthalmologists continue their long and mutually respected professional relationship.

Abstract
BACKGROUND A variety of implants have been used for nasal augmentation. A new implant made of porous polyethylene has recently been available. OBJECTIVE To evaluate the stability (non-extrusion) of MEDPOR porous polyethylene as nasal dorsal implants in Asian patients. METHODS Nineteen patients' charts were reviewed looking for implant displacement, extrusion of porous implants, postoperative bleeding and infection of tissues surrounding the implants in the postoperative follow-ups which range from 3 months to 5 years. RESULTS No postoperative bleeding, infection, or displacement or extrusion of porous implants was noted. Explantation was easily performed in one patient. CONCLUSION Porous polyethylene is stable as a nasal dorsal implant in Asians. Explantation can also be performed with ease if needed.
