Objective:This study aimed to report 9 venous thromboembolism(VTE)cases after extracranial otologic surgery and analyze the potential risk factors.Study design:Case series.Setting:Single tertiary-level academic center.Methods:Totally,9 cases of VTE were identified among adults who underwent extracranial otologic surgery at our hospital from January 2018 to December 2020.Caprini risk scores were calculated,and comprehensive preoperative,operative,and postoperative clinical data within 14 days were collected to assess the evidence of VTE.Results:The median age of 9 patients was 64 years old.Among them,7(77.8%)patients presented with intramuscular vein thrombosis,1(11.1%)patient had deep vein thrombosis,and 1(11.1%)patient experienced pulmonary embolism.Preoperatively,8(88.9%)patients had low or middle Caprini risk scores(≤4)with an average of 2.67±0.47 points.The average Caprini scores for all patients were 4.44±0.35 on postoperative day(POD)1 and 5.67±0.64 on POD14.D-dimer levels were collected,indicating an average of 0.55±0.17 mg/FEU preoperatively,8.53±3.94 mg/FEU at day 1,and 3.76±0.45 mg/FEU at POD14.In postoperative period,7(77.8%)patients experienced vertigo/dizziness and/or head immobility/bed rest.Conclusion:The present study highlighted that patients with low-and middle-risk of VTE undergoing otologic surgery should be also vigilant about postoperative VTE.Vertigo/dizziness and/or head immobility/bed rest in postoperative period should be considered as minor risk factors for developing VTE in patients undergoing extracranial otologic surgery.Conducting perioperative assessments,including Caprini risk score evaluation,Ddimer testing,and venous ultrasound of lower extremities,is recommended to ensure patients’safety. 展开更多

Objective To test a modified otologic drill under different drilling conditions for its ability to identify drilling faults and stop drilling.Methods Based on force analysis and previous works,an otologic drill was modified and equipped with three sensors.Under various conditions,the drill was used to simulate three drilling faults and normal drilling,and signals from the drill were analyzed to extract the characteristic signal.A multi-sensor information fusion system and a stop program were designed to recognize drilling faults and stop drilling.Results Signals from each sensor changed consistently in response to drilling condition changes,with high repeatability and regularity.The average identification rate was 72.625%,68.575%,70.5% and 81.3% respectively for the three simulated drilling faults and normal drilling.The stop program stopped drilling in 0.2~ 0.3 seconds when a drilling faults was detected.Conclusions This study shows that the forces acting on the drill bit change predictably in the three simulated drilling conditions;that using suitable BP neural networks,the drilling faults can be reliably identified,and that a stop program based upon characteristic signal recognition can stop drilling quickly upon detecting drilling faults.This lays a foundation for development of a system capable of predicting drilling faults and automatic drill control.Further studies are being undertaken for practical application of such a system. 展开更多

Hypothesis:Three-dimensional(3D)printed temporal bones are comparable to cadaveric temporal bones as a training tool for otologic surgery.Background:Cadaveric temporal bone dissection is an integral part of otology surgical training.Unfortunately,availability of cadaveric temporal bones is becoming much more limited and concern regarding chemical and biological risks persist.In this study,we examine the validity of 3D-printed temporal bone model as an alternative training tool for otologic surgery.Methods:Seventeen otolaryngology trainees participated in the study.They were asked to complete a series of otologic procedures using 3D-printed temporal bones.A semi-structured questionnaire was used to evaluate their dissection experience on the 3D-printed temporal bones.Results:Participants found that the 3D-printed temporal bones were anatomically realistic compared to cadaveric temporal bones.They found that the 3D-printed temporal bones were useful as a surgical training tool in general and also for specific otologic procedures.Overall,participants were enthusiastic about incorporation of 3D-printed temporal bones in temporal bone dissection training courses and would recommend them to other trainees.Conclusion:3D-printed temporal bone model is a viable alternative to human cadaveric temporal bones as a teaching tool for otologic surgery. 展开更多
