Background Correction of post traumatic and post-ablative orbita defects remains a challenge for the maxillofacial surgeon. The purpose of such intervention is the restoration of both function and aesthetics by anatomical reconstruction of the bony orbitawalls, with attention to the orbitavolume. Unfortunately, the results of such interventions today are still somewhat unpredictable. The aim of this study is to determine whether 3D virtual planning combined with intra-operative navigation can increase the predictability of the outcome in function and aesthetics. Study design Retrospective study. Demographic data, diagnostic and surgical parameters will be collected of all patients undergoing orbital surgery between 01/01/2012 and 31/12/2016 at the department. Pre- en postoperative orbit volume will be determined based on CT-analysis in Brainlab software, and compared to the non-defected orbit.
In patients suffered from floor fractures, there are 21.9% complaining about diplopia before fracture repair surgery and 20.8% after operation. Even after 6 months, there still are 16.4% had similar conditions. Investigators are planned to find predicting factors to prevent such conditions from happening.
In craniofacial trauma, the involvement of orbital structures is noted in up to 40% of cases (Ellis 1985). Post-traumatic orbital deformities caused by incorrect reconstruction of orbital dimensions are severe complications causing enophthalmos, diplopia and visual acuity disturbance. To prevent such complications, immediate repair of orbital injuries with the restoration of normal anatomy is indicated in orbital floor fractures. With the help of biodegradable implants small and medium-sized defects are easily managed (Büchel 2005, Lieger 2010). In extensive fractures however, only calvarian bone and titanium mesh considered to provide a sufficient support of the orbital content. Calvarial bone can be difficult to mould and to adapt to the form and size of the orbital lesion. In addition, donor site morbidity cannot be disregarded. Orbital reconstruction mesh on the other hand is always available and easier to apply. There are however important requirements for these meshes, such as biocompatibility, excellent stability, optimal adaptability and patient comfort. Recently, the company Medartis developed a titanium mesh featuring a low profile. In order to regain normal function, normal anatomy has to be re-established. It therefore seemed reasonable to assess an implant, which would facilitate orbital reconstruction without disturbing normal anatomy by its size, profile height or properties. The purpose of this study was to assess the use and accuracy of the low profile titanium mesh for primary internal orbital reconstruction.
A retrospective review to assess the performance and clinical predictive value of a novel software program (Maxillo) designed to perform complex volumetric analysis with application in the field of orbital trauma.
Patients with orbital injuries are entered into the trial. Age: 20 - 70. After obtaining appropriate consent, they are entered into either a control arm where reconstruction of the orbit is done with a titanium mesh (established practice) or the experimental arm where reconstruction is by a bioresorbable implant made of polycaprolactone. Patients are followuped at 1 week, 1 month, 3 months, 6 months & 12 months. CT scan of the orbits are performed preop, 6 months & 12 months. End point is the 12 month follow-up appointment. Visual acuity, range of motion, enophthalmos & diplopia are assessed in follow-up.
