Abstract
Surgical simulation is becoming an increasingly common training tool in residency programs. The first objective was to implement real-time soft-tissue deformation and cutting into a virtual reality myringotomy simulator. The second objective was to test the various implemented incision algorithms to determine which most accurately represents the tympanic membrane during myringotomy.

The algorithms included element removal, direction prediction, and Delaunay cutting. The simulator was stable and capable of running in real time on inexpensive hardware. A face-validity study was then carried out using a validated questionnaire given to eight otolaryngologists and four senior otolaryngology residents. Each participant was given an adaptation period on the simulator, was blinded to the algorithm being used, and was presented the three algorithms in a randomized order.</AbstractText><AbstractText Label="RESULTS" NlmCategory="RESULTS">A virtual reality myringotomy simulator with real-time soft-tissue deformation and cutting was successfully developed. The simulator was stable, ran in real time on inexpensive hardware, and incorporated haptic feedback and stereoscopic vision. The Delaunay cutting algorithm was found to be the most realistic algorithm representing the incision during myringotomy (P < .05). The Likert and visual analog scales had strong correlations, suggesting good internal reliability.</AbstractText><AbstractText Label="CONCLUSIONS" NlmCategory="CONCLUSIONS">The first virtual reality myringotomy simulator is being developed and now integrates a real-time deformable tympanic membrane that appears to have face validity. Further development and validation studies are necessary before the simulator can be studied with respect to training efficacy and clinical impact.</AbstractText><CopyrightInformation>Copyright © 2012 The American Laryngological, Rhinological, and Otological Society, Inc.</CopyrightInformation></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Ho</LastName><ForeName>Andrew K</ForeName><Initials>AK</Initials><AffiliationInfo><Affiliation>Biomedical Engineering Graduate Program, University of Western Ontario, London, Ontario, Canada.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Alsaffar</LastName><ForeName>Hussain</ForeName><Initials>H</Initials></Author><Author ValidYN="Y"><LastName>Doyle</LastName><ForeName>Philip C</ForeName><Initials>PC</Initials></Author><Author ValidYN="Y"><LastName>Ladak</LastName><ForeName>Hanif M</ForeName><Initials>HM</Initials></Author><Author ValidYN="Y"><LastName>Agrawal</LastName><ForeName>Sumit K</ForeName><Initials>SK</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList><ArticleDate DateType="Electronic"><Year>2012</Year><Month>05</Month><Day>07</Day></ArticleDate></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>Laryngoscope</MedlineTA><NlmUniqueID>8607378</NlmUniqueID><ISSNLinking>0023-852X</ISSNLinking></MedlineJournalInfo><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName MajorTopicYN="N" UI="D000465">Algorithms</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D003198">Computer Simulation</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D005246">Feedback</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D006801">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D021621">Imaging, Three-Dimensional</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D007396">Internship and Residency</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D008876">Middle Ear Ventilation</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000193">education</QualifierName><QualifierName MajorTopicYN="Y" UI="Q000379">methods</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D008953">Models, Anatomic</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D010036">Otolaryngology</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000193">education</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D011795">Surveys and Questionnaires</DescriptorName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="N" UI="D014432">Tympanic Membrane</DescriptorName><QualifierName MajorTopicYN="Y" UI="Q000601">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName MajorTopicYN="Y" UI="D014584">User-Computer Interface</DescriptorName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="received"><Year>2011</Year><Month>11</Month><Day>14</Day></PubMedPubDate><PubMedPubDate PubStatus="revised"><Year>2012</Year><Month>3</Month><Day>15</Day></PubMedPubDate><PubMedPubDate PubStatus="accepted"><Year>2012</Year><Month>3</Month><Day>26</Day></PubMedPubDate><PubMedPubDate PubStatus="aheadofprint"><Year>2012</Year><Month>5</Month><Day>7</Day></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2012</Year><Month>5</Month><Day>9</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="pubmed"><Year>2012</Year><Month>5</Month><Day>9</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2012</Year><Month>10</Month><Day>6</Day><Hour>6</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="doi">10.1002/lary.23361</ArticleId><ArticleId IdType="pubmed">22566189</ArticleId></ArticleIdList></PubmedData></pubmed></record>Pour manipuler ce document sous Unix (Dilib)
