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.
Computer-Assisted Laparoscopic Myomectomy

As with any surgery, careful patient selection is the key to success and to avoiding unanticipated conversion to laparotomy. Each surgeon has his or her own comfort level regarding which patients are appropriate candidates for computer-assisted surgery based on the anticipated difficulty of the procedure. To improve patient selection, we strongly recommend preoperative imaging with magnetic resonance imaging (MRI) [9]. MRI is essential in helping surgeons plan out a procedure by detailing the size and location of each myoma. Furthermore, the images can be displayed throughout the procedure and used intraoperatively as a guide. As a general rule, based on the first 750 such operations performed by our team (with a 0.1% reported conversion to open surgery), patients with fewer than 15 total myomas, with a leading myoma of less than 15 cm in size, are appropriate candidates for robotic myomectomy [3].

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.
The interest of FE simulation for the reduction of tibial plateau fracture using balloon inflation

Computer-assisted surgery has the potential to facilitate this task by the simulation of a per-operative —during the surgery— models. A considerable amount of study exists on the biomechanical behavior after balloon kyphoplasty —with cement injection—, however per-operative simulation to evaluate the kinematics of the fragments remains unknown.
