ABSTRACT Background Virtual surgical planning (VSP) with simple cutting templates could help surgeons preoperatively plan scapula reconstructions in the vertical and horizontal orientations. Methods Virtually, eight defects were created ten healthy mandibles reconstructed subject‐specific vertically horizontally. In clinical series, 15 single‐piece mandible planned in‐house VSP guided compared freehand reconstructions. Results placement outperformed dice score (DSC) Hausdorff‐95 for all but...
Abstract Background Advanced head and neck malignancies with underlying bony involvement often require aggressive oncological resection of large segments the oral cavity including mandible. These patients vascularized donor osseous free tissue transfer to reconstruct significant defects. Traditionally, bone is harvested on its vascular supply shaped defect in a hand fashion (FHS). However, virtual surgical planning (VSP) has emerged as method optimize reconstructive outcomes decrease...
Abstract Background This study virtually compares patient‐specific fibular and scapular reconstructions for maxillectomies. Methods Nine maxillectomy defects were created on 10 maxillas reconstructed with fibulas scapulas. Reconstructions compared restoring midface cephalometrics, dental implantability, pedicle length. Results Of 90 defects, the vertically oriented scapula provided improved orbital floor maxillary height ( p < 0.001), albeit at cost of implantability to fibula 0.001). In...
Objectives/Hypothesis Virtual surgical planning (VSP) for reconstructions of advanced mandibular neoplasms that have distorted the contour mandible is challenging, as premorbid shape unknown. We introduce a novel modeling technique, based on statistical model (SSM), has learned normal from set 84 mandibles, such given diseased mandible, can determine its shape. Methods Eighty‐four control mandibles were used to generate an SSM. Various defects created, and SSM was applied predict original...
The study's objective is to assess the feasibility and utility of VSP for maxillary reconstruction with scapular free flap.An open-source platform was used create models simple guides. Clinical, operative, postoperative data were collected.Ten patients in cohort 18 non-VSP control included study. There a significant reduction operative time (256.0 ± 69.4 vs. 448.1 108.2 min, p < 0.01), tracheotomy rate (20% 72%, increased two-team utilization (80% 0%, 0.01) better reconstructive accuracy...
Poorly contoured mandibular reconstruction plates are associated with postoperative complications. Recently, a technique emerged whereby preoperative patient-specific reconstructive (PSRP) developed in the hopes of eliminating errors plate-bending process. This study’s objective is to determine if reconstructions performed PSRP more accurate than manually plates. Ten Otolaryngology residents each two ex vivo reconstructions, first using followed by plate. Reconstruction time, CT scans, and...
This study investigated the effectiveness of vocabulary learning tasks based on Technique Feature Analysis framework. The framework provides criteria for evaluating tasks. correlation between predictability and task’s effect retention. employed an experimental design in which participants were assigned to three different involving 15 target words. designed vary presence outlined Analysis. Learners’ knowledge word forms meanings was assessed immediately one week later. results provided mixed...
ABSTRACT Background This study assesses the feasibility of real‐time surgical navigation to plan and guide sequential steps during mandible reconstruction on a series cadaveric specimens. Methods An image‐guided (IGS) system was designed including customized fibula fixation devices with reference frames an accompanied software. The mandibular fibular segmental osteotomies were performed using IGS in all five patients. Procedural time cephalometric measurements recorded. Results Five...
It is hypothesized that patients who are actively provided with more treatment-related education may report increased satisfaction and have improved overall outcomes. The aim of this study was to demonstrate the feasibility an audiovisual platform in undergoing head neck surgery investigate whether using module reported satisfaction.
In the realm of research, detection/recognition text within images/videos captured by cameras constitutes a highly challenging problem for researchers. Despite certain advancements achieving high accuracy, current methods still require substantial improvements to be applicable in practical scenarios. Diverging from detection images/videos, this paper addresses issue license plates amalgamating multiple frames distinct perspectives. For each viewpoint, proposed method extracts descriptive...
Mandibular meshes segmented from computerized tomography (CT) images contain rich information of the dentition conditions, which impairs performance shape completion algorithms relying on such data, but can benefit virtual planning for oral reconstructive surgeries. To locate alveolar process and remove area, we propose a tooth segmentation method including preprocessing step using non-rigid registration, an active contour model, constructive solid geometry (CSG) operations. An easy-to-use...
