Abstract
The detachment and reattachment of inferior oblique (IO) have been done by ophthalmologists in inferomedial orbital wall fracture repair to avoid inducing a new diplopia in patients post-operatively. However, doing them in orbital wall reconstruction in patient who underwent maxillectomy for a malignancy has not been described yet. We describe a case where a disinserted inferior oblique was reattached after titanium mesh implantation to prevent diplopia after the surgery. This is the case of a 40-year-old male diagnosed with recurrent bilateral nasomaxillary ameloblastoma who underwent total maxillectomy of the right with removal of the inferomedial orbital wall, and detachment and reattachment of inferior oblique with no resulting inferior oblique palsy and diplopia from hypotropia or incyclotorsion. This is the first report, to our knowledge, to describe reattachment of IO in its approximate insertion during reconstruction of the inferomedial orbital wall after total maxillectomy from a malignancy with no resulting diplopia.

Abstract
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.

Abstract
Background Detachment of the inferior oblique muscle may be necessary under certain circumstances to repair a large inferomedial orbital fracture involving the orbital strut. This study aimed to evaluate the outcomes of patients who underwent surgeries with and without inferior oblique muscle reattachment after its detachment to repair the orbital wall fractures. Methods Forty patients who underwent repair of combined floor and medial orbital wall fracture involving the orbital strut at a single tertiary institution between January 2014 and December 2020 were reviewed. Groups 1 and 2 comprised 20 patients each, who underwent surgery with inferior oblique muscle detachment without and with reattachment, respectively, and were followed up for at least 6 months postoperatively. Enophthalmos, Goldmann diplopia test, alignment test, ocular motility test, and orbital inferomedial angle ratio were the outcome measures. Results Statistically significant improvement was observed in ocular motility, diplopia, and enophthalmos postoperatively at the 1- and 6-month follow-up (p < 0.01). The mean postoperative inferomedial angle ratio (102.28 ± 10.62%) was improved significantly compared with the preoperative inferomedial angle ratio (115.61 ± 4.38%) (p = 0.004) in all patients. After surgery, inferior oblique muscle underaction was observed in seven and six patients in groups 1 and 2, respectively, which was associated with preoperative extraocular movement limitation and strabismus. Two patients showed diplopia in both groups at the last follow-up; they had inferior oblique muscle underaction but no enophthalmos. Conclusion Orbital fracture repair with or without inferior oblique muscle reattachment was clinically effective and safe; however, patients with preoperative strabismus and extraocular motility limitation should be informed of the increased risk of postoperative complications.

Abstract
PURPOSE We present our experience of titanium-milled two-piece patient-specific implants (PSIs) for primary reconstructions of extensive orbital floor and medial wall fractures (EOFMFs) and evaluate their postoperative functional and aesthetic outcomes in relation to commercially available implants. METHODS We included all patients with primary reconstructions (< 22 days from injury) of EOFMFs treated in our department between January 2011 and October 2020. Extensive orbital floor and medial wall fracture was defined as involvement of orbital floor, medial wall and maxilloethmoidal junction; a fracture defect 5 mm or more; defect size more than a third of both inferior and medial walls; and Jaquiéry classification III or more. Patient characteristics, details of fracture defects and surgeries, postoperative outcomes and implant positions were retrospectively evaluated and compared between study groups. RESULTS Nineteen patients were included: 5 with two-piece PSIs and 14 with commercial implants. Implant position was good in 4/5 patients with two-piece PSIs and 2/14 with commercial implants. Revision surgery, globe malposition (GMP) > 2 mm, significant diplopia and poor implant position were more frequent in patients with commercial implants than two-piece PSIs. None of the patients with a good overall implant position had any significant postoperative symptoms. CONCLUSION Extensive orbital fracture reconstructions are somewhat rare, and surgical treatment is associated with a high rate of complications and postoperative symptoms. Titanium-milled two-piece PSIs are well suited for primary reconstructions of EOFMFs, as they lead to more precise reconstructions and fewer postoperative symptoms than commercially available implants.

Abstract
The reconstruction of an orbit after complex craniofacial fractures can be extremely demanding. For satisfactory functional and aesthetic results, it is necessary to restore the orbital walls and the craniofacial skeleton using various types of materials. The reconstruction materials can be divided into autografts (bone or cartilage tissue) or allografts (metals, ceramics, or plastic materials, and combinations of these materials). Over time, different types of materials have been used, considering characteristics such as their stability, biocompatibility, cost, safety, and intraoperative flexibility. Although the ideal material for orbital reconstruction could not be unanimously identified, much progress has been achieved in recent years. In this article, we summarise the advantages and disadvantages of each category of reconstruction materials. We also provide an update on improvements in material properties through various modern processing techniques. Good results in reconstructive surgery of the orbit require both material and technological innovations.

Abstract
PURPOSE Reconstructive surgery after craniofacial trauma aim to restore orbital anatomy for function and aesthetic reasons. The purpose of this study is to improve postoperative orbital symmetry with the use of prebent prefabricated titanium implants. METHODS In this retrospective study, patients with combined unilateral medial wall and floor fractures who underwent orbital reconstruction surgery were selected. The angle of inferomedial orbital strut (AIOS) was measured at 3 standard locations on preoperative facial computed tomography guided scans of the nonfractured orbit in the coronal view and used as a guide to bend the prefabricated titanium implants intraoperatively. The corresponding values were measured on the postoperative computed tomography and compared for symmetry. RESULTS Out of 83 patients recruited for the study, 54 were in the prebent group while 29 were in the control group. All other demographics were similar among the 2 groups. Anterior AIOS has a difference of 4.9° between 2 orbits in the prebent group whereas a difference of 15.5° was noted in the nonprebent group. For middle AIOS, a difference of 4.7° was noted in the prebent group whereas nonprebent group had a difference of 14.1°. For posterior AIOS, the prebent group had a difference of 3.8° versus 14.1° in the nonprebent group. The difference in AIOS at all 3 points between the prebent and nonprebent group were significant. CONCLUSIONS Anatomical prefabricated titanium plates are versatile implants that facilitate orbital reconstruction. Prebending of these implants according to the fellow orbit can achieve better surgical outcomes in a cost-effective manner.

Abstract
OBJECTIVES To evaluate the safety, efficacy, and feasibility of an endoscopic transconjunctival inferior fornix and precaruncular approach for repair of combined orbital medial wall and floor fractures involving the inferomedial strut. METHODS A retrospective study was performed in 84 patients with combined orbital medial wall and floor fractures involving the inferomedial strut. All patients underwent surgery by endoscopic transconjunctival inferior fornix and precaruncular approach. A large polyester mesh plate was implanted to cover the fracture defect. The enophthalmos, diplopia, and surgical complications were evaluated pre- and postoperatively. Patients were followed for at least 6 months. RESULTS A total of 84 patients (55 men and 29 women) with a mean age of 36.88 ± 12.95 years were included in this study. Preoperatively, all 84 patients had an enophthalmos >2 mm, and the mean exophthalmometry measurement was 11.6 ± 2.14 mm. Diplopia was presented in 33 patients. Postoperatively, good symmetry was acquired in 81 of 84 patients, with a mean improvement of 3.02 ± 0.99 mm in the enophthalmos (P < 0.05). Recovery from diplopia occurred in 32 of 33 patients. A new onset of diplopia occurred postoperatively in 13 of the remaining 51 patients, only to recover spontaneously after 1 month. One patient suffered retrobulbar hemorrhage after surgery and was cured by conservative therapy. No other serious complications occurred. CONCLUSIONS The endoscopic transconjunctival inferior fornix and precaruncular approach is a promising management technique for combined orbital medial wall and floor fractures involving the inferomedial strut.

Abstract
The aim of the study was to assess factors leading to revision surgery and implant position of primary orbital fracture reconstructions. A retrospective cohort included patients who underwent orbital floor and/or medial wall fracture reconstruction for recent trauma. Demographics, fracture type, surgery and implant-related variables, and postoperative implant position were analyzed. The overall revision surgery rate was 6.5% (15 of 232 surgeries). The rate was highest in combined midfacial fractures with rim involvement (14.0%), lower in zygomatico-orbital fractures (8.7%), and lowest in isolated blowout fractures (3.8%). Fracture type, orbital rim fixation and implant malposition predicted revision. The best positioning was achieved with patient-specific milled titanium implants (mtPSI) and resorbable materials, whereas the poorest with preformed three-dimensional titanium plates. Combined midfacial fractures with rim involvement in particular have a high risk for orbital revision surgery. Within the limitations of the present study, mtPSIs should be preferred in the reconstruction of primary orbital fractures if possible.

Abstract
PURPOSE Complex bony orbital defects are reconstructively challenging due to loss of intraoperative anatomical landmarks and adjacent support. Presized and precontoured porous polyethylene-titanium implants (Medpor Titan 3D Orbital Floor Implant) are designed to reestablish normal orbital floor and medial wall anatomy and are modeled after anatomically averaged orbits. This is the first study to report clinical outcomes with this implant. METHODS This retrospective case series reviewed clinical data and outcomes for patients undergoing orbital reconstruction with a presized and precontoured porous polyethylene-titanium orbital implant from January 2016 to June 2018. RESULTS A total of 34 orbits of 33 patients were identified (mean age: 43 ± 16 years, 70% men). Most bony defects were a result of trauma and included large orbital floor deformities (100%), medial wall defects (74%), disrupted inferomedial struts (68%), and broken posterior ledges (82%). Symptomatic diplopia (73%) and enophthalmos (89%, mean: 3.7 ± 2.1 mm) were common preoperatively. Many cases were revisions (44%). Mean follow up was 7.8 ± 6.7 months. All patients had improved globe positioning, enophthalmos, and hypoglobus. Seven patients had persistent postoperative diplopia: 6 responded to prism therapy and 1 required strabismus surgery. One patient required retrobulbar hematoma drainage and 1 patient required implant explantation due to chronic infection. CONCLUSIONS Commercially available presized and precon toured porous polyethylene-titanium implants are useful for complex orbital bony defects and can achieve functional improve ments in diplopia, enophthalmos, and extraocular motility with a low incidence of postoperative complications or revisional surgery.

Abstract
ABSTRACT The reconstruction of combined orbital floor and medial wall fractures is challenging due to the surgical approach and implant stability. A 0.5 mm thickness rigidity custom made titanium alley implant was created by 3-dimensional printing with electron-beam additive manufacturing. The implant was designed to cover the entire surface of the inferomedial orbit based on the flipped the contralateral orbit images. Although the cost was expensive, the use of three-dimensional printed implants for extensive orbital wall fractures was useful for decreasing operative time, and can be accessed with a limited surgical approach with a precise fit.

Abstract
A 24-year-old male athlete, injured by a cricket bat during training, was transferred to the hospital with an open head bleeding trauma in the medial part of his right eye. He was conscious, with no memory loss and dizziness. A medial orbital wall fracture (MOWF) with a foreign body presence was depicted in X-ray. Head computed tomography scan confirmed initial diagnosis and revealed the complete fracture of ethmoid sinuses. Temporary sutures were placed initially to close the wound and prevent trauma's infection. The ophthalmological exam revealed strabismus of the right eye due to medial rectus muscle entrapment and consequent diplopia in the horizontal gaze. After two weeks, surgery was planned to remove the foreign body, restore eye mobility, and correct diplopia. The wooden foreign body (2.5cm x 1cm) was removed with immediate decompression of the medial rectus muscle. The fracture was repaired by an open approach, a mesh net was placed and sutured to the periosteum for bone stabilization and regeneration. Fifteen days postoperatively, visual acuity was 10/10, ocular mobility was normal, and diplopia disappeared. Imaging is essential in diagnosis' confirmation and reconstructive surgery planning, without postoperative complications and complete patient's rehabilitation. The current report highlights the value of reconstructive surgery in orbital structures' preservation in complex MOWF cases. In such cases, the foreign body that entraps medial rectus muscle should be removed in time in order to prevent the orbital content displacement towards the gap created by the fractured bone with consequences enophthalmos and diplopia, as well as consecutive intraorbital infections. Eye preservation in the correct position eliminates strabismus.

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
Orbital fractures are common. In patients where there is significant loss of the medial wall and orbital floor, anatomic prebent 3-dimensional plates allow efficacious restoration of orbital volume. However, the large size of these plates can result in technical difficulties with plate placement, especially in fractures with complete loss of 2 walls of the orbit. In this article, the authors review the pertinent anatomy of the bony orbit with respect to fracture and landmarks in fracture reduction. The authors also note the 3 most commonly encountered problems with the placement of anatomic plates: poor exposure, failure to identify the posterior ledge for the plate, and rotational issues with plate placement resulting in impingement. Technical tips are given to help overcome these issues intraoperatively.

Abstract
PURPOSE This report describes the case of a serious orbital injury in which the globe was completely displaced into the nasal cavity and the orbit was clinically empty. The authors discuss the difficulties encountered in the management of this patient and their principles in the reconstruction of a complex defect. MATERIALS AND METHODS In this rare case of severe injury, the authors used a combined transconjunctival and ethmoidal approach to retrieve the displaced globe from the nasal cavity. This approach allowed ample access to the floor and the medial wall of the orbit; therefore, a single 0.5-mm titanium mesh was bent to fit the combined defect for reconstruction. RESULTS Early combined maxillofacial and oculoplastic surgical intervention resulted in salvage and restoration of the eye with preservation of vision. CONCLUSIONS Stable reconstruction of the maxillo-ethmoidal buttress is of great importance in patients with comminuted injuries. This strut determines the appropriate orbital volume and defines the position of the eye in space. Patients with insufficient restoration of the buttress are always at risk of developing enophthalmos. To replicate the contour of the S-shape of the orbital floor and the slope of the medial wall, the authors support the use of thin implants with rigid fixation on the bony orbit as the most suitable materials to achieve this. Thick implants can be rather difficult to bend, and when this is attempted several times they are more prone to fractures. Conversely, very thin and flexible implants can always be dislodged and cause late enophthalmos.

Abstract
Introduction Radiologic evaluation is mandatory to assess the type of endoscopic approach concerning sinonasal pathology and reconstruction of fractured defects before any treatment modalities are instituted related to medial wall of the orbit. Objective The goal was to provide improved understanding of the lamina papyracea variations and the relationship with the orbital morphometry. Methods This retrospective study was performed using computed tomography scans of 200 orbits and results were compared with respect to age, sex, laterality and LP variations. Results Lamina papyracea variations were categorized as type A, 80.5% (161/200); type B, 16% (32/200); type C, 3.5% (7/200). For medial wall the anterior and posterior lamina papyracea heights and angles were found as 17.14 mm, 147.88° and 9.6 mm, 152.72°, respectively. Also, the length of the lamina papyracea, the mean area of the orbital floor, medial wall, lamina papyracea and orbital entrance were 33.3 mm, 7.2 cm2, 6.89 cm2, 4.51 cm2 and 12.46 cm2 respectively. The orbital height and width were measured as 35.9 mm and 39.2 mm respectively. The mean orbital cavity depth was 46.3 mm from optic foramen to the orbital entrance and the orbital volume was 19.29 cm3. We analyzed the morphometric measurements tending to increase with aging and greater in men and the relationship of them with lamina papyracea types. Conclusion Precise knowledge of the lamina papyracea anatomy using computed tomography is essential for safer and more effective surgery and preforming the dimensions of an implant. In this way, the postoperative complications can be decreased and the best outcome can be provided.

Abstract
BACKGROUND The management of combined orbital floor and medial wall fractures involving the inferomedial strut is challenging due to absence of stable cornerstone. In this article, we proposed surgical strategies using customized 3D puzzle implant preformed with Rapid Prototype (RP) skull model. METHODS Retrospective review was done in 28 patients diagnosed with combined orbital floor and medial wall fracture. Using preoperative CT scans, original and mirror-imaged RP skull models for each patient were prepared and sterilized. In all patients, porous polyethylene-coated titanium mesh was premolded onto RP skull model in two ways; Customized 3D jigsaw puzzle technique was used in 15 patients with comminuted inferomedial strut, whereas individual 3D implant technique was used in each fracture for 13 patients with intact inferomedial strut. Outcomes including enophthalmos, visual acuity, and presence of diplopia were assessed and orbital volume was measured using OsiriX software preoperatively and postoperatively. RESULTS Satisfactory results were achieved in both groups in terms of clinical improvements. Of 10 patients with preoperative diplopia, 9 improved in 6 months, except one with persistent symptom who underwent extraocular muscle rupture. 18 patients who had moderate to severe enophthalmos preoperatively improved, and one remained with mild degree. Orbital volume ratio, defined as volumetric ratio between affected and control orbit, decreased from 127.6% to 99.79% (p < 0.05) in comminuted group, and that in intact group decreased from 117.03% to 101.3% (p < 0.05). CONCLUSION Our surgical strategies using the jigsaw puzzle and individual reconstruction technique provide accurate restoration of combined orbital floor and medial wall fractures.

Abstract
Repairing a large inferomedial blowout fracture remains a challenge to orbital surgeon. The authors restored the fracture using combined transnasal and transorbital approaches using support of both paranasal sinuses. The authors compared surgical results of this novel method with those of the traditional procedure. Of 106 inferomedial blowout fracture patients who underwent surgical treatment between March 2007 and July 2013, 50 patients were selected in our study: 25 patients underwent the traditional procedure as controls, and the other 25 patients underwent orbital wall restoring surgery by our combined approach. Outcomes were evaluated in terms of the orbital volume ratio (OVR) and changes in Hertel scale. The OVR in the experimental group (7.19%) decreased more significantly than in the control group (2.71%) (P < 0.05). In conclusion, the orbit was restored more successfully following orbital wall restoring surgery with dual support than by using the traditional inferomedial blowout fracture procedure.

Abstract
PURPOSE To describe ocular motility and effectiveness of an extended conjunctival incision with reattachment of the inferior oblique muscle to repair combined orbital medial and inferior wall fractures. METHODS The authors retrospectively studied 20 eyes from 20 patients who underwent combined orbital medial and inferior wall fractures surgery with reattachment of the inferior oblique muscle from January 2007 to December 2011. Single large L-shaped implant was inserted into the fracture site. All patients were evaluated preoperatively and postoperatively at 1, 3, and 6 months, by computed tomography, Hertel exophthalmometry, the Hess test of ocular motility, and the Goldmann diplopia test. RESULTS Sixteen patients (80%) had no significant enophthalmos or diplopia after surgery. Inferior oblique motility was not changed in 12 patients (60%) after reattachment of the inferior oblique muscle. After 1 month, inferior oblique underaction was presented in 8 patients (40%) and in 4 patients (20%) after 6 months. Finally, only 2 patients (10%) had the inferior oblique underaction remained, it was not improved. CONCLUSIONS The extended conjunctival incision with reattachment of the inferior oblique muscle for combined orbital wall fracture repair offers a wide surgical field and space for a single large implant insertion and corrects the enopthalmos. The reattachment of the inferior oblique muscle does not contribute to the development of inferior oblique underactions or diplopia that was resolved spontaneously within 6 months after surgery.

Abstract
Fractures of the midface pose a serious medical problem as for their complexity, frequency and their socio-economic impact. Interdisciplinary approaches and up-to-date diagnostic and surgical techniques provide favorable results in the majority of cases though. Traffic accidents are the leading cause and male adults in their thirties are affected most often. Treatment algorithms for nasal bone fractures, maxillary and zygomatic fractures are widely agreed upon whereas trauma to the frontal sinus and the orbital apex are matter of current debate. Advances in endoscopic surgery and limitations of evidence based gain of knowledge are matters that are focused on in the corresponding chapter. As for the fractures of the frontal sinus a strong tendency towards minimized approaches can be seen. Obliteration and cranialization seem to decrease in numbers. Some critical remarks in terms of high dose methylprednisolone therapy for traumatic optic nerve injury seem to be appropriate. Intraoperative cone beam radiographs and preshaped titanium mesh implants for orbital reconstruction are new techniques and essential aspects in midface traumatology. Fractures of the anterior skull base with cerebrospinal fluid leaks show very promising results in endonasal endoscopic repair.

Abstract
BACKGROUND Reconstruction of combined orbital floor and medial wall fractures with a comminuted inferomedial strut (IMS) is challenging and requires careful practice. We present our surgical strategy and postoperative outcomes. METHODS We divided 74 patients who underwent the reconstruction of the orbital floor and medial wall concomitantly into a comminuted IMS group (41 patients) and non-comminuted IMS group (33 patients). In the comminuted IMS group, we first reconstructed the floor stably and then the medial wall by using separate implant pieces. In the non-comminuted IMS group, we reconstructed the floor and the medial wall with a single large implant. RESULTS In the follow-up of 6 to 65 months, most patients with diplopia improved in the first-week except one, who eventually improved at 1 year. All patients with an EOM limitation improved during the first month of follow-up. Enophthalmos (displacement, 2 mm) was observed in two patients. The orbit volume measured on the CT scans was statistically significantly restored in both groups. No complications related to the surgery were observed. CONCLUSIONS We recommend the reconstruction of orbit walls in the comminuted IMS group by using the following surgical strategy: usage of multiple pieces of rigid implants instead of one large implant, sequential repair first of the floor and then of the medial wall, and a focus on the reconstruction of key areas. Our strategy of step-by-step reconstruction has the benefits of easy repair, less surgical trauma, and minimal stress to the surgeon.

Abstract
PURPOSE Blowout fracture characterized by concurrent floor and medial wall fractures is a rare entity. We compared surgical outcomes between a single approach and a double approach in patients with orbital fracture by measuring the postoperative orbital volume. METHODS We confirmed that 21 (8.5%) of a total of 246 patients with orbital fractures had fractures of the medial wall and floor through a retrospective chart review. Of these, 10 patients underwent the single approach and the remaining 11 patients had the double approach. We performed a statistical analysis of changes between the preoperative and postoperative orbital volumes at a 6-month follow-up. RESULTS Compared with the contralateral, nonaffected side, the orbital volume was 115.3 (±6.09)% preoperatively and 106.5 (±6.15)% postoperatively in the single approach group and 118.2 (±11.16)% preoperatively and 108.6 (±13.96)% postoperatively in the double approach. These results indicated that there was a significant difference between the preoperative and postoperative orbital volumes in each group (P < 0.05). However there was no significant difference between the single approach and the double approach (P > 0.05). CONCLUSIONS Our results showed that there were no significant differences in surgical outcomes between the two modalities. The treatment modality may be selected based on the surgeons' preference, as well as the fracture type.

Abstract
Surgical management of medial wall orbital fractures should be considered to avoid diplopia and posttraumatic enophthalmos. Treatment of these fractures remains a challenge for the maxillofacial surgeon because of complex anatomy and limited vision. This article aims to retrospectively evaluate the outcomes in the repair of medial orbital wall fractures using a retrocaruncular approach and titanium meshes, comparing the placement of the titanium mesh with three different techniques: (1) conventional free hand under direct vision, (2) with the assistance of an endoscope, and (c) with the assistance of a navigation system. Eighteen patients who underwent surgery for orbital medial wall fracture were enrolled in the study. On the basis of the implant placement technique, three groups were identified: group 1 (CONV), conventional free hand under direct vision; group 2 (ENDO), endoscopically assisted; group 3 (NAVI), a navigational system assisted (BrainLab, Feldkirchen, Germany). The postoperative quality of orbital reconstruction was assessed as satisfactory in 12 cases, good in 4 cases, and unsatisfactory in 2 cases. Particularly in group 1 (CONV) in four patients out of eight, the posterior ledge of the fracture was not reached by the implant and in one patient the mesh hinged toward the ethmoid. In group 3 (NAVI), in one patient out of five, the posterior ledge of the fracture was not reached. In conclusion, titanium orbital mesh plates and retrocaruncular approach are a reliable method to obtain an accurate orbital medial wall reconstruction. The use of endoscopic assistance through the surgical incisions improves accuracy of treatment allowing better visualization of the surgical field. Navigation aided surgery is a feasible technique especially for complex orbital reconstruction to improve predictability and outcomes in orbital repair.

Abstract
Background Restoring orbital volume in large blowout fractures is still a technically challenge to the orbital surgeon. In this study, we restored the orbital wall using the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses, and we compared the surgical outcome to that of a conventional transorbital method. Methods A retrospective review of all patients with pure unilateral blowout fractures between March 2007 and March 2013 was conducted. 150 patients were classified into two groups according to the surgical method: conventional transorbital method (group A, 75 patients, control group), and the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses (group B, 75 patients, experimental group). Each group was subdivided depending on fracture location: group I (inferior wall), group IM (inferomedial wall), and group M (medial wall). The surgical results were assessed by the Hertel scale and a comparison of preoperative and postoperative orbital volume ratio (OVR) values. Results In the volumetric analysis, the OVR decreased more by the experimental groups than each corresponding control groups (P<0.05). Upon ophthalmic examination, neither the differences among the groups in the perioperative Hertel scale nor the preoperative and postoperative Hertel scales were statistically significant (P>0.05). Conclusions Our surgical results suggest that orbital volume was more effectively restored by the combination of transorbital and transnasal approach with additional supports from the paranasal sinuses than the conventional method, regardless of the type of fracture.
