Surgical simulation applications have been largely limited to the acquisition and assessment of technical skills. Current teaching and assessment of surgical judgment is nonsystematic and prone to error. Interest in methods to enhance the acquisition and assessment of knowledge-based (judgment) skills for intraoperative decision making has led to the application of cognitive task analysis (CTA)...

HYPOTHESIS Describe the incidence, type, and detection method of surgical listing errors and implement a system to reduce errors. DESIGN All errors/discrepancies between the surgical listing and the performed procedure reported to an institutional event line during 2008 were analyzed. SETTING Academic tertiary medical center. MAIN OUTCOME MEASURES Error characteristics and detection mode ...

Accurate understanding of surgical tool-tip tracking error is important for decision making in image-guided surgery. In this Letter, the authors present a novel method to estimate/model surgical tool-tip tracking error in which they take pivot calibration uncertainty into consideration. First, a new type of error that is referred to as total target registration error (TTRE) is formally defined ...

conclusions coccygectomy is a successful treatment in patients unresponsive to conservative treatments for coccydynia. results the patients were followed up for an average of 25.7 months. the results were good in 11 patients, excellent in 1, and fair in only 1 patient. the excellent and good rates amounted to 92.2%. no major complication was seen. patients and methods between october 2010 and d...

introduction: coverage of bone grafts is very important in reconstructive surgery. in edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for upp...

the coverage of soft- tissue defects of the hand specially volar side needs special consideration. although certain local flaps have been described and used for resurfacing the palm, extensive injury requires distant or free flaps for coverage. abdominal pedicle flap has been traditionally used for extensive hand injuries, however there is no doubt that one of the ideal tissues for resurfacing ...

background:the diagnostic accuracy of frozen section as an important source of information in surgical pathology is important not only in the management of surgical patients but also as a measure of quality control in surgical pathology. in this study, we evaluated the diagnostic accuracy of frozen sections over a 6-year period in a teaching hospital in iran. methods: we retrospectively review...
