Quality Assessment and Content Analysis of Youtube Videos on Trabeculectomy

PurposeThe aim of this study is to evaluate the accuracy, quality and reliability of the videos on trabeculectomy on YouTube which is an online video-sharing platform.Scope This paper aims to assess the quality and analyze the content of the videos on Trabeculectomy on YouTube. The material has been obtained by a video search carried out on the Youtube -online video platform- with the keyword “Trabeculectomy”. The material (videos) was examined and selected in accordance with the exclusion criteria (not being in English, duplicate videos, lack of title information of the video, being irrelevant to the subject, videos with only advertising content, videos with a pixel below 240, takes longer than 20 minutes). After the implementation of exclusion criteria, the first ten suitable videos were included in the evaluation.MethodologyRegarding the material, the parameters of the number of views, the number of likes, the number of dislikes, the number of comments, the video duration, the days since the video was uploaded were recorded. Thus, after carving out the secondary data, a number of statistical analyses were performed namely Shapiro-Wilks, Kruskall-Wallis, Mann-Whitney U and Backward Linear Regression. In this framework, statistical analyzes were made via using the Stata software. Statistical significance value (threshold) was accepted as %10 (p<0.1).ResultsAfter the videos were evaluated according to the upload source, it was found that 2 videos were downloaded by the individuals who is not a doctor, 6 videos from doctors and 2 videos from a commercial source. The number of subscribers of the YouTube channels on which these sources have been uploaded was significantly different from each other (p<0.1). When the videos were evaluated according to the information content they provided, it was found that 5 videos had low quality information content, 4 videos had medium quality information content, 1 video had good quality information content, and the video durations were also significantly different from each other (p<0.1). Moreover, it was statistically determined that the parameter affecting the number of views was the number of likes (p<0.1).ConclusionYouTube videos are essentially insufficient as an educational material and an English source of information for the Trabeculectomy. Health professionals need to pay more attention to online platforms so that patients can access accurate information.Categories:Medical Education, Medical Simulation, Surgery

Virtual pre-operative planning in acetabular surgery using a patient-specific biomechanical model: a prospective clinical study.

The first patient-specific biomechanical model for pre-operative planning in acetabular surgery was developed in our institution and validated in previous retrospective studies. The aim of this prospective clinical study was to confirm the previous promising.Between January 2019 and June 2019, every patients operated by the first author for acetabular fracture were included in this prospective study. A biomechanical model was implemented in acustom software made from combination of several open-sources software allowing a biomechanical simulation. The surgery was then performed according to the simulation. Surgery duration, blood loss, radiological results and per- operative complications were recorded.Ten patients were included. Mean simulation time was 22 min ± 4 [range, 18-31]. The mean operative time was 113 min ± 33 [range, 60-180] and mean blood loss was 505 mL ± 189 [range, 100-750]. On Matta’s criteria, anatomic reduction was achieved in 9 of the 10 patients (90%; 0.8 mm ± 1 [range, 0-3]). No per-operative complications were recorded.This study confirms the promising results of pre-operative planning in acetabular surgery based on a patient-specific biomechanical model.The model needs larger-scale prospective validation, but offers a new tool suitable for teaching purposes and for assessment of surgical strategies in acetabular fracture.

Evaluation of Effective Condyle Positioning Assisted by 3D Surgical Guide in Mandibular Reconstruction Using Osteocutaneous Free Flap

In the present study, the reproducibility and postoperative stability of a 3D printed surgical guide were evaluated in mandibular reconstruction with an osteocutaneous free flap (OCFF), including a fibular free flap (FFF) and deep circumflex iliac artery free flap (DCIA). Fifteen patients were enrolled, and a 3D surgical guide was fabricated by simulation surgery using preoperative (T0) Computed tomography (CT) images. Mandibular reconstruction was performed with OCFF using the 3D surgical guide. Postoperative CTs were taken immediately, 1 week (T1), and 6 months (T2) after surgery, to evaluate the reproducibility of the 3D surgical guide and condyle stability. Error of the 3D surgical guide ranged from 0.85 to 2.56 mm. There were no differences in reproducibility according to flap type. Condylar error and error at mandible midpoint were significantly different in FFF. However, there was no difference in DCIA error between the condyle and mandible midpoint. Regarding condyle stability 6 months after surgery, condyles moved more than 2 mm (up to 2.85 mm) in FFF, whereas there were no significant movement in DCIA. Careful intraoperative flap fixation and closed postoperative observation should be considered for stable clinical outcome, especially in the case of FFF.

Application of Computer 3D Digital Technology in Surgical Treatment of Pediatric Skull Deformity

Pediatric skull deformity requires immediate surgery as indicated by increased cranial pressure, mental retardation, impaired or absent vision, cranial deformity, and mental and spiritual defects. This study explores the application value of computer aided simulation in treatment of pediatric skull deformity. The application of computer simulation surgery in the treatment of children with pediatric skull deformity allows surgeons to be familiar with the operation process in advance. The use of computer 3D digital technology for preoperative design planning and simulation can reduce surgical difficulty to a certain extent, improve surgical efficiency, significantly increase intraoperative accuracy, and also reduce the risk of intraoperative bleeding and postoperative complications.

Application of Computer Aided Simulation and Biomechanical Analysis in Treatment of Congenital Sagittal Synostosis

This study explores the application value of computer aided simulation and biomechanical analysis in treatment of congenital sagittal synostosis. The traditional and proposed treatment methods were evaluated by comparing the operation time, blood loss, operation cost and postoperative complications. The application of computer simulation surgery and biomechanical analysis in the treatment of children with congenital sagittal synostosis allows surgeons to be familiar with the operation process and splicing scheme in advance. In particular, computer biomechanical analysis was proposed for the first time to determine the position and quantity of the joint materials, so as to achieve operation's objectives of stability, aesthetics, expansion, significantly improve the surgical efficiency, reduce the cost and postoperative complications.
