RESUMEN

OBJECTIVES: To verify the feasibility and to discuss advantages and disadvantages of a piezoelectric orbitotomy (PO) during Superior Eyelid Endoscopic Transorbital Approach (SETOA). METHODS: Five adult specimens underwent exoscopic/endoscopic SETOA to middle cranial fossa. The surgical corridor was created via piezoelectric orbitotomy by performing three selective and safe micrometric bone cuts providing a one-piece trapezoid bone flap which was repositioned and secured at the end of procedure. A 3D scan of the bone flap allowed us to reconstruct a 3D model and calculate its volume. An illustrative case demonstrating the application of this novel technique was also presented. RESULTS: Anatomical-morphometric quantitative analysis showed a mean bony-volume gain of 1,574.26 mm3 by using PO. PO yielded concrete surgical advantages and theoretical benefits in terms of functional and esthetic outcomes. All osteotomies were micrometric clear-cut and precise, resulting in a very thin bony gap; a complete sparing of soft tissues and neurovascular structures in- and around the orbit was observed. Lateral orbital wall reconstruction by replacing the bone flap aims to mitigate the risk of enophthalmos, proptosis, CSF leakage, pseudomeningocele and pulsatile headache, which represent significant challenges in the relevant literature. CONCLUSION: PO may offer a viable, selective, effective, safe alternative to high-speed drilling during SETOA, especially for patients affected by intra-axial pathologies in which a watertight closure is mandatory. This procedure could prevent/decrease the risk of some of the main postoperative complications associated to the standard SETOA, resulting potentially in better functional and esthetic outcome.

RESUMEN

BACKGROUND: The eyes are the central aesthetic unit of the face. Maxillofacial trauma can alter facial proportions and affect visual function with varying degrees of severity. Conventional approaches to reconstruction have numerous limitations, making the process challenging. The primary objective of this study was to evaluate the application of three-dimensional (3D) navigation in complex unilateral orbital reconstruction. METHODS: A prospective cohort study was conducted over 19 months (January 2020 to July 2021), with consecutive enrollment of 12 patients who met the inclusion criteria. Each patient was followed for a minimum period of 6 months. The principal investigator carried out a comparative analysis of several factors, including fracture morphology, orbital volume, globe projection, diplopia, facial morphic changes, lid retraction, and infraorbital nerve hypoesthesia. RESULTS: Nine patients had impure orbital fractures, while the remainder had pure fractures. The median orbital volume on the normal side (30.12 cm3; interquartile range [IQR], 28.45-30.64) was comparable to that of the reconstructed orbit (29.67 cm3; IQR, 27.92-31.52). Diplopia improved significantly (T(10) = 2.667, p = 0.02), although there was no statistically significant improvement in globe projection. Gross symmetry of facial landmarks was achieved, with comparable facial width-to-height ratio and palpebral fissure lengths. Two patients reported infraorbital hypoesthesia at presentation, which persisted at the 6-month follow-up. Additionally, five patients developed lower lid retraction (1-2 mm), and one experienced implant impingement at the infraorbital border. CONCLUSION: Our study provides level II evidence supporting the use of 3D navigation to improve surgical outcomes in complex orbital reconstruction.

RESUMEN

This paper presents a novel approach to the correction of zygomatic malposition and secondary reconstruction orbital floor fractures, highlighting the use of hydrated acellular dermal matrix (ADM), specifically CGDerm One-Step, in a case where traditional solid implants failed to maintain structural integrity and volume. A 27-year-old woman with persistent facial deformities following a traumatic incident underwent a transformative procedure that utilized ADM for volume correction and structural support, addressing significant challenges such as enophthalmos and facial contour depression. This approach was necessitated by the descent of the entire orbital floor and a previously placed implant (Medpor), leading to unsatisfactory volume correction. By integrating ADM with titanium-reinforced fan plates (Synpor), the surgery successfully restored the patient's facial symmetry and addressed her functional concerns, including diplopia and limited eye movement. Postoperative evaluations demonstrated the long-term effectiveness of this method, with significant improvements in facial contour and eye symmetry. Our findings suggest that ADM, particularly in its hydrated form, offers a reliable alternative to traditional bone grafts and implants for correcting complex craniofacial deformities, providing both aesthetic and functional benefits. This case underscores the importance of adaptable, tissue-mimicking materials in facial reconstructive surgery, offering insights into their potential for broader application in post-traumatic facial corrections.

RESUMEN

INTRODUCTION: Long-term enophthalmos and diplopia resulting from orbital bone loss pose significant challenges in reconstructive surgery. This study evaluated the effectiveness of patient-specific porous titanium implants (PSIs) for addressing these conditions. MATERIALS AND METHODS: This retrospective study involved 12 patients treated at Croix-Rousse Hospital, Lyon, from April 2015 to April 2022 who underwent late reconstruction via PSI for unilateral complex orbital bone loss. These implants were customized via 3D mirroring techniques on the basis of high-resolution computed tomography (CT) scans of the patients' unaffected orbits. RESULTS: All 12 patients presented with significant preoperative enophthalmos, with an average displacement of 3.24 mm, which was effectively corrected postoperatively to an average of 0.17 mm (p < 0.001). Orbital volume notably improved from a preoperative average of 3.38 mL to 0.37 mL postsurgery (p < 0.001). Functional improvements were evident as both enophthalmos and diplopia resolved completely. The Lancaster test revealed an improvement in the visual field, with 83.3 % of patients achieving normal results postoperatively. DISCUSSION: By ensuring anatomical accuracy, patient-specific porous titanium implants, tailored from patient-specific imaging and fabricated via advanced 3D printing technology, provide a precise, effective, and reliable solution for reconstructing complex orbital defects and performing complicated revision surgeries.

RESUMEN

INTRODUCTION: Congenital enophthalmos is a rare condition characterized by posterior displacement of the globe, often associated with bony orbital anomalies or whole globe development defects. The purpose of this report is to present two unrelated cases of congenital enophthalmos secondary to anomalous accessory orbital bands and to describe characteristics of orbital imaging that differentiate this condition from the other causes. METHODS: The case records of two patients who presented with congenital enophthalmos and were discovered to have anomalous accessory orbital extraocular muscle bands were reviewed. The clinical features, initial diagnosis, high resolution magnetic resonance imaging (MRI) findings, and surgical outcomes were noted. A 3-dimensional reconstruction model was used to understand the approach and surgical management in one of the cases. RESULTS: Both patients presented with unilateral severe enophthalmos, globe retraction, and restricted ocular motility in all directions since birth. High-resolution MRI of the orbits revealed a short anomalous band, isointense to the muscle, arising from a rectus muscle belly and attaching to the posteroinferior part of the globe adjacent to the optic nerve. The caliber of the extraocular muscles and ocular motor nerves was normal. In one patient, surgery was not pursued due to the extreme posterior location of the band with proximity to the optic nerve. In the other patient, the deviation did not improve, despite successfully severing the accessory band, due to extensive scarring. CONCLUSION: Anomalous accessory orbital extraocular muscle bands are a rare and often overlooked cause of congenital enophthalmos when associated with limited ocular motility. Imaging the orbit can aid in diagnosis and help differentiate it from other causes. Safe surgical approaches to address the problem are limited, and available approaches may not be effective. These two cases highlight that the management of accessory extraocular muscle bands causing enophthalmos can be extremely challenging and difficult to improve even with intensive surgical intervention.

RESUMEN

BACKGROUND: Orbital floor fractures result in critical changes in the shape and inferior rectus muscle (IRM) position. Radiological imaging of IRM changes can be used for surgical decision making or prediction of ocular symptoms. Studies with a systematic consideration of the orbital floor defect ratio in this context are missing in the literature. Accordingly, this study on human cadavers aimed to systematically investigate the impact of the orbital floor defect ratio on changes in the IRM and the prediction of posttraumatic enophthalmos. METHODS: Seventy-two orbital floor defects were placed in cadaver specimens using piezosurgical removal. The orbital defect area (ODA), orbital floor area (OFA), position and IRM shape, and enophthalmos were measured using computed tomography (CT) scans. RESULTS: The ODA/OFA ratio correlated significantly (p < 0.001) with the shape (Spearman's rho: 0.558) and position (Spearman's rho: 0.511) of the IRM, and with enophthalmos (Spearman's rho: 0.673). Increases in the ODA/OFA ratio significantly rounded the shape of the IRM (ß: 0.667; p < 0.001) and made a lower position of the IRM more likely (OR: 1.093; p = 0.003). In addition, increases in the ODA/OFA ratio were significantly associated with the development of relevant enophthalmos (OR: 1.159; p = 0.008), adjusted for the defect localization and shape of the IRM. According to receiver operating characteristics analysis (AUC: 0.876; p < 0.001), a threshold of ODA/OFA ratio ≥ 32.691 for prediction of the risk of development of enophthalmos yielded a sensitivity of 0.809 and a specificity of 0.842. CONCLUSION: The ODA/OFA ratio is a relevant parameter in the radiological evaluation of orbital floor fractures, as it increases the risk of relevant enophthalmos, regardless of fracture localization and shape of the IRM. Therefore, changes in the shape and position of the IRM should be considered in surgical treatment planning. A better understanding of the correlates of isolated orbital floor fractures may help to develop diagnostic scores and standardize therapeutic algorithms in the future.

RESUMEN

Enophthalmos is a severe complication of primary reconstruction following orbital floor fractures, oncological resections, or maxillo-facial syndromes. The goal of secondary orbital reconstruction is to regain a symmetrical globe position to restore function and aesthetics. In this article, we present a method of computer-assisted orbital floor reconstruction using a mirroring technique and a custom-made titanium or high-density polyethylene mesh printed using computer-aided manufacturing techniques. This reconstructive protocol involves four steps: mirroring of the healthy orbit computer tomography files at the contralateral affected site, virtual design of a customized implant, computer-assisted manufacturing (CAM) of the implant using Direct Metal Laser Sintering (DMLS) or Computer Numerical Control (CNC) methods, and surgical insertion of the device. Clinical outcomes were assessed using 3dMD photogrammetry and computed tomography measures in 13 treated patients and compared to a control group treated with stock implants. An improvement of 3.04 mm (range 0.3-6 mm) in globe protrusion was obtained for the patients treated with patient-specific implants (PSI), and no major complications have been registered. The technique described here appears to be a viable method for correcting complex orbital floor defects needing delayed reconstruction.

RESUMEN

Study Design: Prospective Interventional study. Objective: To evaluate the efficiency of Matrixmidface preformed Orbital plates for three-dimensional reconstruction of orbital floor and medial wall fractures. Methods: This prospective institutional clinical study was conducted on a group of 14 patients who underwent repair of orbital floor and medial wall fracture defects using Matrixmidface Preformed Orbital plates and open reduction and internal fixation of associated fractures. The following parameters were studied preoperative and postoperative enophthalmos, hypoglobus, orbital volume; correction of diplopia, intraoperative and postoperative complications. Results: All 14 patients were males aged between 19 and 42 years. The most common mode of injury was found to be road traffic accidents (RTAs) followed by self-fall and trauma at workplace. Orbital fractures were associated with other concomitant maxillofacial fractures in 12 patients (85.7%) while 2 patients (14.3%) had pure blowout fractures. Significant improvement of enophthalmos was noted from preoperative period to 1 week, 6 weeks, and 6 months postoperatively (P value .02, .01, and .01, respectively). Out of 11 patients with preoperative hypoglobus, 5 patients (45.45%) had persistent hypoglobus in the immediate postoperative period which reduced to 4 patients (36.36%) at 6 weeks postoperatively (p value .00). The postoperative orbital volume of fractured side ranged from 20.3 cm3 to 26.76 cm3 with a mean of 23.50 cm3 ± 1.74. The mean difference between the volumes of the repaired and uninjured sides was found to be .27 cm3 ± .39 (P value .02) denoting that the reconstruction of the orbit closely approximated that of the uninjured side. Conclusions: The Matrixmidface Preformed Orbital plate provides exceptional reconstruction of the orbital blowout fracture defects and ensures satisfactory results clinically and radiographically. The plate ensures an approximate recreation of topographical anatomy of the orbit and adequately restores the orbital volume. It provides adequate correction of asymmetry, hypoglobus, enophthalmos and attempts to restore eye movements, without causing any significant postoperative complication.

RESUMEN

The diagnostic criteria for silent sinus syndrome (SSS) are still controversial, especially for the post-traumatic/surgery cases that are, nowadays, excluded from the diagnosis of SSS because lacking of spontaneously. We present a systematic review of the last 10 years and our case series of SSS associated to previous trauma/surgery, proposing a new interpretation of SSS. In this work, following the PRISMA guide lines for systematic reviews, we collected 86 articles published on PubMed, Cochrane Library and Medline Plus since 2013 to 2023 about SSS. We divided them in six groups forming the structure of the review: (1) epidemiology, (2) clinical presentation, (3) imaging, (4) etiopathogenesis, (5) sss and craniofacial trauma and (6) treatment. We reported two explicative clinical cases: two men of 34 and 37 years old, involved in motorcycle accident in 2020 and 2014, respectively, and underwent surgery. They came back in 2023 referring diplopia documented by Hess-Lancaster test. CT-scan reported two clear cases of SSS. Basing on what is reported in literature, and basing on our experience, the post-traumatic/surgery SSS are more frequent than the idiopathic ones. Our proposal is to considered them as two individual entities. We propose to adopt the name of Post-traumatic sinus syndrome, or CDR syndrome (Catalfamo-De Rinaldis), for all cases that respect four specific diagnostic criteria reported into the text.

RESUMEN

BACKGROUND: We hypothesized that application of acellular dermal matrix (ADM) over the orbital septum overlying the herniated orbital fat to tighten and strengthen the attenuated orbital septum in lower blepharoplasty would allow successful repositioning of the herniated orbital fat within the bony orbit. METHODS: The author prospectively compared the cosmetic outcomes of lower blepharoplasty using ADM with standard blepharoplasty. We evaluated recurrence of eyelid bulging and tear trough deformity, volume of the lower periorbital region, and enophthalmos and eyelid droop 1 year after surgery. RESULTS: Twenty-two of the 24 enrolled patients completed the study. There was no significant difference in recurrence of eyelid bulging and tear trough deformity between standard blepharoplasty and blepharoplasty with ADM graft groups. In the standard blepharoplasty group, the volume of the lower periorbital region decreased significantly after surgery. In the blepharoplasty with ADM graft group, there was no significant change in the volume of the lower periorbital region after surgery. In the standard blepharoplasty group, there was no significant change in eyelid droop on either side after surgery. In the blepharoplasty with ADM graft group, the eyelid droop decreased significantly after surgery on the right side but showed no significant change on the left side. There was no significant change in enophthalmos after surgery for either group. CONCLUSIONS: This study demonstrated that ADM graft provided effective support for maintaining the replaced orbital fat in lower blepharoplasty. In the long-term, blepharoplasty with ADM graft might be effective in slowing development of age-related enophthalmos.

RESUMEN

Purpose: To describe a rare case of acquired enophthalmos in a patient with idiopathic orbital inflammatory disease after treatment with systemic corticosteroids. Observations: Orbital socket contracture produces a non-traumatic enophthalmos and is most frequently reported as a consequence of orbital trauma or metastatic fibrosis. A previously healthy 64-year-old male presented with 3-month history of binocular diplopia and left proptosis, hypoglobus, supraduction deficit, and compressive neuropathy. Imaging techniques showed a left orbital mass; laboratory tests and biopsy of the mass lead to the diagnosis of idiopathic orbital inflammatory disease. Systemic corticosteroids were administered and, surprisingly, the patient developed left enophthalmos with eyelid retraction. Conclusions and Importance: Although extremely unusual, orbital socket contracture can cause enophthalmos and visual morbidity in patients with idiopathic orbital inflammatory disease treated with corticosteroids.

RESUMEN

El tratamiento de la asimetría facial en pacientes con microftalmos o cavidades anoftálmicas adquiridas suele requerir cirugías reconstructivas agresivas. En los últimos años se han publicado trabajos sobre el uso de rellenos para optimizar la simetría del tejido orbitario, como técnicas mínimamente invasivas.Por este motivo, hemos realizado una revisión sistemática de la literatura publicada hasta el momento sobre la administración orbitaria de rellenos para el tratamiento de la pérdida de volumen. Se identificaron 14 artículos que cumplían con los criterios de selección; en los que se analizó el material utilizado, la técnica de inyección, el estudio anatómico de los pacientes antes del procedimiento y la presencia de complicaciones asociadas. Los materiales utilizados como relleno son: la grasa autóloga, la hidroxiapatita cálcica, el colágeno, el ácido hialurónico o el gel de poliacrilamida. Se aplicaron técnicas estándar de inyección peribulbar y retrobulbar, con escasas complicaciones asociadas, siendo la má grave el desarrollo de cuadros vaso-vagales. El seguimiento de los pacientes suele limitarse en la mayoría de los estudios a 12 meses, con variaciones significativas en la exoftalmometría posprocedimiento. En conclusión, la utilización de rellenos parece una práctica segura y con buenos resultados, aunque se precisan estudios con tiempo de seguimiento más prolongado que los publicados hasta el momento.

Standard peribulbar and retrobulbar injection techniques were applied, with few associated complications, the most serious being the development of vasovagal symptoms. Patient follow-up is usually limited in most studies to 12 months.In Conclusion, the use of fillers seems to be a safe practice, with good results and few complications, although studies with longer follow-up times than those published to date would be required.

RESUMEN

Introduction: Late presentations of post-traumatic residual orbital roof deformities ensuing from old, unaddressed orbital injuries, can be extremely challenging to manage and quite complicated to correct, owing to proximity of the brain and frontal sinus, malunion or bony fusion of the displaced, delicate orbital fracture fragments, necrosis of entrapped extraocular muscles and progressive intraorbital soft tissue fibrosis and adhesions. There exists a paucity in literature on delayed repair of displaced and comminuted orbital roof fractures and late reconstruction of the three-dimensional architecture of the orbital frame and internal orbit. Aim & Objectives: To present an unusual case of severe post-traumatic residual orbital roof deformity, resulting in longstanding aesthetic disfigurement and persisting functional deficits, and its successful management. Material & Methods: The patient had sustained orbital injuries sixteen months ago, on being punched in the face at a boxing tournament. The increased orbital volume produced by an impure blowout fracture of the left orbital roof, with comminution of the upper and lower orbital rims, had resulted in considerable cosmetic deformity, discomfort as well as functional debility, all of which were successfully and efficaciously managed by an innovative use of a Titanium Orbital Plate for orbital roof reconstruction. Discussion: Overlooked, undetected or ignored derangements in intraorbital volume and contour, can lead to severe cosmetic disfigurement in the form of enophthalmos, hypoglobus, entropion, telecanthus, palpebral fissure width narrowing and ptosis; in addition to crippling functional deficits, such as diplopia, blurred vision, levator dysfunction, restricted ocular motility and reduced visual range and acuity. Results & Conclusions: An innovative Titanium mesh orbitoplasty enabled achievement of both, the aesthetic and functional goals of reconstruction of the distorted bony orbit, with successful correction of severe functional and aesthetic deficits.

RESUMEN

Silent sinus syndrome (SSS) is a relatively rare clinical condition occurring in the maxillary sinus exhibiting progressive enophthalmos and hypoglobus. The communication between the orbit and maxillary antrum due to trauma further leads to changes in the maxillary sinus. This could lead to the development of negative pressure within the maxillary sinus, collapse of antrum walls, and sucking in of orbital contents. Here, we present a case of a delayed orbital trauma, which was not treated initially. The patient's complaint was a constant feeling of a sunken right eye along with restriction in eye movements. On examination, the clinical and radiographic features were consistent with SSS. Orbital floor reconstruction was performed with the help of a titanium mesh for the correction of hypoglobus and enophthalmos. During follow-up, the patient showed no recurrence of the presenting functional and esthetic complaints. This clinical entity needs prompt diagnosis and early intervention so as to prevent further complications.

RESUMEN

Introduction Orbital floor fractures are routinely encountered in facial trauma. Many factors influence the final outcome of the orbital floor surgery, time interval and the extent of other facial bone fractures are the two factors which can significantly influence the postoperative outcome following orbital floor reconstruction. Our study aims to find the ideal time for intervention and the association of other factors in the final outcome of orbital floor reconstruction. Methods A retrospective and prospective cohort study of patients who were operated at Pondicherry Institute of Medical Sciences for orbital floor fractures, between 2011 January and 2017 July. All the data were entered on an Excel work sheet and statistically analyzed. Results In our study 8 patients (8/29, 27.58%) had diplopia prior to surgery, 5 patients (5/29, 17.24%) had complete recovery following surgery and 3 patients (3/29, 10.34%) had persistence of diplopia postoperatively. Patients with diplopia operated prior to 7 days were found to have significant improvement in postoperative diplopia. Patients with 5 or more facial fractures were found to have persistence of diplopia, infraorbital numbness, and enophthalmos postoperatively. Conclusion Our study suggests that early intervention, before 7 days improves the outcome in patients with diplopia and provides a better result postoperatively. In our study preoperative diplopia and infraorbital numbness and postoperative persistence of enophthalmos, diplopia, and paresthesia were found more in patients with 5 or more facial bone fractures. Our study suggests a poor postoperative outcome when 5 or more facial bones are fractured.

RESUMEN

BACKGROUND: Little attention has been paid to combined orbital floor and medial wall fractures with the involvement of the inferomedial orbital strut. Managing this particular fracture can prove challenging. However, various innovative techniques have been introduced to assist with the process. Our study focuses on sharing our approach to orbital wall reconstruction using navigation guidance and titanium-reinforced porous polyethylene plates, specifically cases involving the inferomedial orbital strut. We believe that implementing a navigation system can effectively lead surgeons to the fracture site with utmost safety. Also, we hypothesized that this navigation system is beneficial to use singe fan titanium-reinforced porous polyethylene plates with orbital wall fractures involving IOS while minimizing possible complications. METHODS: We retrospectively reviewed 131 patients with medial orbital wall and orbital floor fractures with or without combined other facial bone fractures who underwent orbital wall reconstruction by a single surgeon from May 2021 to May 2023. Amongst, we identified fourteen orbital wall fractures involving the inferomedial orbital strut. We used a subciliary incision as the only approach method for performing titanium-reinforced porous polyethylene plates for navigation-guided orbital wall reconstruction. Patients were followed up for at least three months. RESULTS: All cases were effectively resolved using titanium-reinforced porous polyethylene plates. There were no complications during the patient's complete recovery, confirmed clinically and radiologically. Based on the serial CT results, it was discovered that implanted titanium-reinforced porous polyethylene plates successfully covered the defect. CONCLUSION: Based on our retrospective analysis, it has been determined that among the 131 recorded cases of orbital fractures, 14 of them (or 10.7%) involved the inferomedial orbital strut. Navigation-guided reduction using titanium-reinforced porous polyethylene (TR-PPE) plates can lead to predictable, reliable, and excellent outcomes for treating orbital fractures involving the inferomedial orbital strut without complications.

RESUMEN

A 7-year-old male child presented with complaints of lagophthalmos and lid retraction of the right eye since birth. Magnetic resonance imaging (MRI) showed diffuse thickening of right superior rectus and levator-palpebrae complex along with a hypointense, irregular, and ill-defined lesion in the adjoining fat abutting the lacrimal gland. Biopsy from the lesion showed diffuse orbital fibrosis. Another 3-year-old female child presented with complaints of her right eye appearing smaller and inability to move the right eye freely since birth. MRI showed thickening of right superior and medial recti with diffuse retrobulbar hypointense fibrotic strands. The findings were suggestive of orbital fibrosis. Congenital orbital fibrosis is an extremely rare orbital pathology with very few cases described in the literature. The most common clinical features are motility restriction, restrictive strabismus, upper lid retraction, enophthalmos, and proptosis. The diagnosis can be made on imaging but requires biopsy for confirmation. Management is mostly conservative in the form of refractive and amblyopia therapy.
