Computer-Assisted Secondary Reconstruction of Unilateral Post-Traumatic Orbital Deformity
Published in Niall MH McLeod, Peter A Brennan, 50 Landmark Papers every Oral & Maxillofacial Surgeon Should Know, 2020
This study contributed to the beginnings of computer-assisted surgery in oral and maxillofacial surgery. Many larger cohort studies on intraoperative navigation have been performed since, with emphasis of its use in orbital reconstruction. Yu et al. described several indications for intraoperative navigation in a cohort study of 104 patients (ZMC fractures, TMJ ankyloses, fibrous dysplasia, mandibular angle hypertrophia, jaw tumours and foreign bodies).1 They found a mean error between planning and surgical result of 1.46 ± 0.24 mm and concluded navigation to be a useful supplement.

Domb et al. [36] performed a multisurgeon retrospective analysis of 1980 THA patients, looking at modes of guidance, including a mechanical alignment rod, TAL referencing and fluoroscopy-guided, computer-navigated and robotic-guided systems. The target for cup positioning was defined as 40° of inclination and 20° of anteversion. Computer-navigated and robotic-assisted THAs were associated with a significantly greater number of acetabular components within Lewinneck’s safe zone but when adjusted for Callanan’s safe zones robotic-assisted acetabular navigation improved accuracy significantly when compared to all modalities. As with other studies looking at computer-assisted surgery, there was significantly less variance in the computer-navigated and robotic-assisted groups when compared with all other methods. It is important to note that there was one case of robotic-assisted failure requiring conversion to the conventional method of cup placement in the study. This is a reminder of the importance of surgery being supervised or performed by an experienced surgeon in order to use good judgement when required. Further theoretical limitations on employing such equipment include set-up and running costs, restriction of implant choice for robotic system compatibility, exposure to radiation via CT and operative time.

Virtual planning is quickly becoming the standard of care for planning complicated surgical procedures across many specialties.3 Computer-assisted surgery supports the surgeon while making difficult decisions with diagnosis, operational planning and even intra-operative navigation. Surgery requiring movement of skeletal components in three dimensions for many different types of surgical problems requires sophisticated planning tools to precisely navigate through the surgery planning and the operation itself. The combination of this virtual planning technology, along with the fabrication of stereolithic models, splints and custom hardware, as well as the translation of this data into computer navigation systems will increase safety and accuracy. Virtual reality is the new frontier of surgery.
Use of computer-assisted surgery in the orbit

Advances in computer-assisted surgery (CAS) systems over the last several years have led to a growth in their application in surgery. They have become useful tools in the fields of neurosurgery, skull base surgery, and sinus surgery. CAS has been shown to help surgeons localize a bony landmark in real-time compared to pre-acquired patient imaging to within 1 to 2 mm.1 Use of CAS is gaining increasing traction within the oculoplastic surgery community, especially in cases with complex orbital pathology.2–5 Hussein et al. published results from a survey showing that while CAS has not been adopted broadly by orbital surgeons, those that do feel that the technology improves accuracy in achieving the surgical endpoint.6 Use of CAS has shown to be useful in repairing internal orbital fractures, particularly in the selection of the orbital implant pre-operatively.7 CAS has also been shown to help in orbital decompression surgery for thyroid eye disease.8–10 The goal of this paper is to present the application of computer-assisted surgery in pre-operative planning, intra-operative navigation, and post-operative analysis in a variety of complex orbital pathology.

In both medicine and dentistry, the past several decades have seen tremendous improvement in accuracy and efficiency of surgical procedures as a result of the application of computer-assisted surgery technology. In many medical fields, dynamic computer-assisted surgery has become the standard of care. Neuronavigation has shaped contemporary neurosurgery, and with continued innovation, the applications of neuronavigation are vast. At this point, there is no question that neuronavigation offers benefits over conventional neurosurgery techniques.
