“…During surgery, all target points were far from the surface, so the system is applicable. The microscope distance was preserved near 300 mm to surgical field, as previously done by Bernardeschi et al (10) The bone implanted markers, Fiducial marker, are accepted as the gold standard for registration (9,11). The totally fixed titanium screw with central head cavity was very suitable for accurate registration and point defining and decreased the error of measurement.…”

“…The current research used the touch surface registration on the lateral side of the head (mastoid to temporal area). In optoelectronic IGS, the laser surface registration method is widely used in ENT surgery (mainly rhinology and anterior skull base) (11), yet this method is not available for electromagnetic IGS systems as performed in this study. The probe tip is fine and could be used easily and safely.…”

Background: The use of Image Guided Surgery (IGS) systems at lateral skull base surgery is controversial due to the limitation of the accuracy of the systems. The intraoperative accuracy of the IGS is dependent on deferent parameters, mainly the precision of the system, resolution of utilized imaging, rigidity of the reference frame/adaptor, registration method, calibration of the utilized instruments, and intraoperative movement of the reference markers. Objectives: In this study the researchers examined the target registration error of an electromagnetic IGS system on different important structures of lateral skull base through different approaches. This study compared two registration methods and two scanning systems. Methods: In 10 formaldehyde-fixed human cadaver heads, 69 target points were marked with titanium screws for determining target registration errors. The target points were facial nerve, lateral semi-circular canal, geniculate ganglion, superior semi-circular canal, internal auditory canal, and the foramen rotundum. Seven heads were scanned using a Cone Beam CT Scanner (CBCT) and three heads were scanned using a CT scanner. Three screws were implanted around the mastoidectomy cavity as Fiducial Markers (FM). Two different registration methods were applied, including point based registration using the FM versus surface registration. All samples were dissected via the middle cranial fossa approach, retrosigmoid approach, and transmastoid approaches. Results: The overall accuracy of the IGS-system was 1.2 mm and plusmn; 0.15 mm. Optimum accuracy was reached with CBCT-scan and the FM registration marker. Navigation using CT scans with the surface registration method, using CT scans with FM registration method, and using CBCT-scans with surface registration method had lower accuracy, respectively, yet their difference was not statistically significant (P > 0.5). The best accuracy was noted on the facial nerve in the mastoid approach (mean 0.8 mm). Conclusions:The feasibility of the use of an electromagnetic IGS system in lateral skull base, surgery using Cone Beam CT as well as conventional CT scanner with fiducial marker registration as well as surface registration were evaluated. The accuracy was best at the lateral region of the temporal bone and decreased on further medial targets, such as lower cranial nerve and trigeminal ganglion.

“…[11] Alternatively, invasive registration, the use of which may be life-threatening, is often adopted in skullbased surgical cases so as to achieve higher accuracy of 1-2 mm. [12,13] In otologic surgery, the invasive registration method is typically employed in order to meet the accuracy requirement of less than 1 mm. However, this approach requires the operation of a drill, necessitating the use of local anesthesia and increasing pains and infections, in addition to delayed wound healing.…”

Purpose: This article proposed and investigated the application of bonebed-malleus short process registration in minimally invasive cochlear implantation, and assessed the value of the proposed strategy for image-guided otologic surgery. Materials and methods: Ten temporal bone specimens were marked with both shallow and deep targets in order to measure registration resolutions. Two registration methods were applied. Method A (a new registration method) consisted of bonebed-malleus short process registration, while method B (traditional registration method) comprised registration using four titanium screws attached at the mastoid surface. The target registration errors (TRE) were measured at both the shallow and deep fiducial targets. After registration achieved by method A, percutaneous cochlear drilling was conducted on the other eight temporal bone specimens in order to observe the deviation from the target point and entry point. Results: Using method A, the error observed at the shallow fiducial markers of specimens was less than 1 mm, while the error observed at the deep fiducial markers was approximately equal to 1 mm. No significant difference was observed when results were compared with the application of method B. In eight studied cases using method A, drilling operations were successfully conducted. The deviations from the target point and the entry point were 0.84 ± 0.30 and 0.66 ± 0.51 mm, respectively. Conclusions: Results of the present study indicated that the new registration method demonstrated identical accuracy when compared to traditional registration method, achieved less invasiveness. Thus, the proposed method might be a feasible registration method for image-guided otologic surgery due to its mild invasiveness and high accuracy.

“…Navigationguided bone surgery requires registration to match the image to the patient's bone. Investigators have developed two registration methods; one uses temporarily implantable artificial bone markers [1,5,14], and the other uses prominent anatomic points of bone [6,[15][16][17].…”

Background Technical errors during navigation-assisted bone tumor resection may occur by: (1) incorrect registration of images and corresponding anatomic points of bone sent to the navigation system; and (2) incorrect fusion of two or more images that have been transported to the navigation system. Questions/purposes We investigated new methods of navigation surgery to minimize technical errors during the registration and image fusion processes and specifically asked whether a navigated cannula probe would reduce unnecessary soft tissue dissection, and allow percutaneous registration and implantation of a reference base tracker in the margin of bone to be resected. Methods We performed direct MRI-guided navigation surgery without image fusion on a patient with osteosarcoma using absorbable pins as temporary implanted bone markers that prevent artifacts on MR images. Results Direct MRI-guided navigation surgery was possible using bone markers. A navigated cannula probe allowed percutaneous registration and a navigated bladeshaped probe provided a real-time check on the narrow osteotomy gap. The surgical procedure was facilitated by implantation of a reference base tracker on the margin of bone to be resected. Conclusions Our modified technique of MRI-guided navigation surgery for patients with a malignant bone tumor may reduce processing errors by increased accuracy and be helpful for joint preserving surgery.

Use of anatomic or invasive markers in association with skin surface registration in image-guided surgery of the temporal bone

Abstract: In the first protocol, PA did not improve after the registration of the landmarks, and PA of the target was evaluated as 4.9+/-0.64 mm. In the second protocol, PA was reduced after screw registration for all landmarks with a mean PA ranging from 0 to 2.3 mm.
