The aim of our study was to evaluate the biodegradable plates (PG910/PDO) for reconstruction of various sizes of the orbital floor defects in the blow-out fractures. We included patients who had an impure blow-out fracture. All patients had a recent trauma and also the surgical intervention was done between 1 and 10 days after trauma. The amount of the orbital floor defect was measured in each case through computed tomography scan. In the surgical intervention, a biodegradable plate was used for the reconstruction of the orbital floor defect along with titanium miniplates used for bone fixation in orbital rim. Due to aesthetic reasons, all patients underwent secondary surgery including removal of titanium miniplates after 18 months. The orbital floor was reevaluated during the removal of the miniplates. The clinical evaluation of remnant defects and biodegradable plates (presence of complete or partial resorption) were documented for each patient. In our study a total of 15 patients (10 males and 5 females) underwent the orbital floor reconstruction using biodegradable miniplates. The size of the orbital floor defects was meanly 3.51 ± 1.29 cm2. Results demonstrated that 4 out of 15 patients had a remnant defect after resorption of the biodegradable plate. In 10 out of 15 patients, the biodegradable plates completely replaced with fibrous tissues after 18 months. Remaining five patients had partial resorption of plates. There was not any relationship between the defect size and the remnant defects ( p > 0.05). A significant relationship was seen between the defect size and the plates’ resorption rate ( p < 0.001). There is a significant relationship between the resorption rate and the remnant defect. The risk to have remnant defects have been increased as the plates had incomplete resorption. The use of biodegradable plates is an appropriate option for reconstruction of the orbital floor defects. The defect size does not have any effect on the stability of the plate. However, incomplete plate resorption increases the risk of remnant defects in the orbital floor. The larger defects lead to slow degradation of biodegradable plates.

Orbital Blowout Fractures

Orbital blowout fractures are a common occurrence following orbital trauma. Depending on the size of the defect and the contents that have herniated or incarcerated, possible sequelae include enophthalmos, diplopia, dystopia, and entrapment. Surgical intervention aims to prevent or alleviate this through the use of a bone graft or an alloplastic implant to reconstitute the continuity of the orbit. However, in doing so, the implant itself may result in the unexpected adherence of the periorbita, resulting in orbital adherence syndrome. We present two cases of orbital adherence syndrome following the use of titanium mesh for orbital floor reconstruction. In both cases, we also delineate the management of this syndrome. Our first patient reported good recovery after surgical intervention to relieve the tethering to the titanium mesh and subsequent placement of a smooth interface implant. The other patient was managed nonsurgically with resolution of symptoms. We highlight possible signs that might suggest the need for early surgical intervention. Orbital adherence syndrome is a poorly described and understood phenomenon and appears to occur after the use of large-pored titanium mesh for orbital reconstruction. Prevention is possible through careful patient selection and the placement of a smooth interface medium in the initial surgery.

Background Enophthalmos in a patient with an opacified hypoplastic maxillary sinus, without sinus symptomatology, describes the silent sinus syndrome. A current trend is to perform endoscopic maxillary antrostomy and orbital floor reconstruction as a single-staged operation. A two-staged approach is performed at our institution to avoid placement of an orbital floor implant in the midst of potential infection and allow for the possibility that enophthalmos and global ptosis may resolve with endoscopic antrostomy alone, obviating the need for orbital floor reconstruction. Methods A retrospective review identified four patients with silent sinus syndrome evaluated between June 1999 and August 2001. Patients presented to our ophthalmology department with ocular asymmetry, and computerized tomography (CT) scanning confirmed the diagnosis in each case. Results There were three men and one woman, with ages ranging from 27 to 40 years. All patients underwent endoscopic maxillary antrostomy. Preoperative enophthalmos determined by Hertel's measurements ranged from 3 to 4 mm. After endoscopic maxillary antrostomy, the range of reduction in enophthalmos was 1–2 mm. Case 2 had a preoperative CT scan and a CT scan 9 months after left endoscopic maxillary antrostomy. Volumetric analysis of the left maxillary sinus revealed a preoperative volume of 16.85 ± 0.06 cm3 and a postoperative volume of 19.56 ± 0.07 cm3. This represented a 16% increase in maxillary sinus volume postoperatively. Orbital floor augmentation was avoided in two patients because of satisfactory improvement in enophthalmos. In the other two patients, orbital reconstruction was performed as a second-stage procedure. There were no complications. Conclusion Orbital floor augmentation can be offered as a second-stage procedure for patients with silent sinus syndrome. Some patients’ enophthalmos may improve with endoscopic antrostomy alone.

The aim of this study is to present a narrative review of the properties of materials currently used for orbital floor reconstruction. Orbital floor fractures, due to their complex anatomy, physiology, and aesthetic concerns, pose complexities regarding management. Since the 1950s, a myriad of materials has been used to reconstruct orbital floor fractures. This narrative review synthesises the findings of literature retrieved from search of PubMed, Web of Science, and Google Scholar databases. This narrative review was conducted of 66 studies on reconstructive materials. Ideal material properties are that they are resorbable, osteoconductive, resistant to infection, minimally reactive, do not induce capsule formation, allow for bony ingrowth, are cheap, and readily available. Autologous implants provide reliable, lifelong, and biocompatible material choices. Allogenic materials pose a threat of catastrophic disease transmission. Newer alloplastic materials have gained popularity. Consideration must be made when deliberating the use of permanent alloplastic materials that are a foreign body with potential body interactions, or the use of resorbable alloplastic materials failing to provide adequate support for orbital contents. It is vital that surgeons have an appropriate knowledge of materials so that they are used appropriately and reduce the risks of complications.
