“…VPS placement using optical stereotactic navigation has shown a high accuracy in catheter positioning, while the main limitations are that for referencing, the head of the patient needs to be fixed in a head holder and pins and the preoperative set-up can be time-consuming [7], leading to longer operation times. There are electromagnetic stereotactic navigation systems not requiring head fixation; however, the accuracy when used for neurosurgical procedures might be lower than for navigation systems where the head is fixed [8][9][10][11][12]. US-G VPS placement was described as a valid alternative to stereotactic navigation, while head fixation as well as preoperative planning and registration are not needed [13,14].…”

Background Ventriculoperitoneal shunt (VPS) placement is one of the most frequent neurosurgical procedures and the operation is performed in a highly standardised manner under maintenance of highest infection precautions. Short operation times are important since longer duration of surgery can increase the risk for VPS complications, especially infections. The position of the proximal ventricular catheter influences shunt functioning and survival. With freehand placement, rates of malpositioned VPS are still high. Several navigation techniques for improvement of shunt placement have been developed. Studies comparing these techniques are sparse. The aim of this study is to prospectively compare ultrasound (US) guided to stereotactic navigated shunt placement using optical tracking with the focus on operation time and efficiency. Methods In this prospective randomised, single-centre, partially-blinded study, we will include all patients undergoing VPS placement in our clinic. The patients will be randomised into two groups, one group undergoing US-guided (US-G) and the other group stereotactic navigated VPS placement using optical tracking. The primary outcome will be the surgical intervention time. This time span consists of the surgical preparation time together with the operation time and is given in minutes. Secondary outcomes will be accuracy of catheter positioning, VPS dysfunction and need for revision surgery, total operation and anaesthesia times, and amount of intraoperative ventricular puncture attempts as well as complications, any morbidity and mortality. Discussion To date, there is no prospective data available comparing these two navigation techniques. A randomised controlled study is urgently needed in order to provide class I evidence for the best possible surgical technique of this frequent surgery.

“…The dynamic navigation system can better solve the current problems of static guides and implant robots while ensuring implant accuracy [ 10 ]. Of course, several factors affect the accuracy of dynamic navigation in clinical applications, such as the accuracy of image data [ 11 ], the precision of calibration and registration [ 12 ] and the accuracy of the dynamic navigation system itself [ 13 ]. Dentists' familiarity with the hardware and software of the dynamic navigation system directly affects the accuracy of the navigation system [ 14 ].…”

Background Dynamic navigation systems have a broad application prospect in digital implanting field. This study aimed to explore and compare the dynamic navigation system learning curve of dentists with different implant surgery experience through dental models. Methods The nine participants from the same hospital were divided equally into three groups. Group 1 (G1) and Group 2 (G2) were dentists who had more than 5 years of implant surgery experience. G1 also had more than 3 years of experience with dynamic navigation, while G2 had no experience with dynamic navigation. Group 3 (G3) consisted of dentists with no implant surgery experience and no experience with dynamic navigation. Each participant sequentially placed two implants (31 and 36) on dental models according to four practice courses (1–3, 4–6, 7–9, 10–12 exercises). Each dentist completed 1–3, 4–6 exercises in one day, and then 7–9 and 10–12 exercises 7 ± 1 days later. The preparation time, surgery time and related implant accuracy were analyzed. Results Three groups placed 216 implants in four practice courses. The regressions for preparation time (F = 10.294, R2 = 0.284), coronal deviation (F = 4.117, R2 = 0.071), apical deviation (F = 13.016, R2 = 0.194) and axial deviation (F = 30.736, R2 = 0.363) were statistically significant in G2. The regressions for preparation time (F = 9.544, R2 = 0.269), surgery time (F = 45.032, R2 = 0.455), apical deviation (F = 4.295, R2 = 0.074) and axial deviation (F = 21.656, R2 = 0.286) were statistically significant in G3. Regarding preparation and surgery time, differences were found between G1 and G3, G2 and G3. Regarding implant accuracy, differences were found in the first two practice courses between G1 and G3. Conclusions The operation process of dynamic navigation system is relatively simple and easy to use. The linear regression analysis showed there is a dynamic navigation learning curve for dentists with or without implant experience and the learning curve of surgery time for dentists with implant experience fluctuates. However, dentists with implant experience learn more efficiently and have a shorter learning curve.
