Filter by:The goal of this preclinical trial is to learn about the benefits and limitations of novel robotic devices for microsurgery, based on different levels of microsurgical experience. The main questions it aims to answer are: Is robot-assisted microsurgery faster, better and more ergonomic than conventional microsurgery in a preclinical standardized setting? Participants will perform microvascular anastomoses on 1.0-mm-diameter artificial silicone vessels using a conventional manual approach versus a novel robot-assisted approach. Researchers will compare the performance of novices, advanced participants and experts to evaluate the role of microsurgical experience when learning the new technique.
Endovascular coiling has become a strategy of choice of intracranial aneurysms due to its minimally invasiveness. However, there has few prospective randomized controlled studies on the comparison of therapeutic effect between endovascular coiling and microsurgical clipping, especially the latter via keyhole approaches, which has been widely used in recent years. Based on the data of a single center, a randomized controlled study was conducted on patients with ruptured anterior circulation aneurysms suitable for both endovascular and extravascular treatment, including endovascular coiling, microsurgical clipping via conventional craniotomy and keyhole approaches, in order to compare the efficacy of the above strategies and provide more objective basis for treatment selection for operators.
The purpose of this study was to compare the effectiveness of microsurgical and macrosurgical approaches on CPFs plus SCTGs for the treatment of localized gingival recession defects (Miller class I or II) over the course of 6 months based on clinical periodontal parameters, periodontal phenotypes, and the postoperative complaints and satisfaction levels of the patients. We hypothesized that root coverage achieved through microsurgery in Miller I or II gingival recessions would improve clinical periodontal outcomes and the periodontal phenotype, with greater postoperative comfort and aesthetic satisfaction in comparison with conventional macrosurgical techniques. Miller Class I and II gingival recession defects, at least 3.0 mm deep, were selected and randomly assigned to receive micro or macrosurgical techniques. Both techniques were performed using a coronally positioned flap with a subepithelial connective tissue graft. Plaque and gingival indices, gingival recession depth and width, probing pocket depth, bleeding on probing, clinical attachment level, width of keratinized gingiva, aesthetic score and percentage of root coverage, postoperative complaints, and satisfaction of the participants completing the study were evaluated at follow-up 1st, 3rd and 6th months.
This study reports the experience in free tissue transfer in the elderly population by a single surgeon in the private practice setting in Mexico city and the potential criticism that could arise from adverse events in lower-volume practice situations will be addressed. Investigator will answer the question about the age as the variable of interest in this series in which age was not a factor in deciding reconstructive methods, and examine complication rates.
A single-center, prospective, randomized, controlled intervention trial to validate an inexpensive practice model for acquisition of microsurgical skills. Following a pre-assessment microsurgical skills task, participants were randomized to either an intervention group to build a micro-stellated icosahedron, or to a control group with no specific task assigned. A post-assessment microsurgical skills task was given to all participants after two weeks. Videos of pre- and post-assessments were masked and independently rated by two ophthalmologists using Video-based Modified Objective Structure Assessment of Technical Skill (OSATS) scoring criteria. Analyses were done to determine improvement in time required to complete tasks and in scores between pre- and post- assessments.
Microdialysis is admitted to be reliable by numerous surgeons to monitor flaps. Nevertheless, a few authors reported follow up with microdialysis in bone flaps, and they all described the position of the catheter in the surrounding soft tissue muscle. This surrounding soft tissue is not always the reflect of bone vascularisation. The aim is to study the feasibility of a follow up of microanastomosed bone flaps with microdialysis. To reach this goal, investigators perform a clinical prospective research project untitled MTM project
