ABSTRACT
Objective@#To investigate the application of 3D printing in the flipped classroom in the practice teaching of otolaryngology-head and neck surgery.@*Methods@#A total of 68 medical undergraduates of the Grade 2013 in Air Force Medical University were divided into experimental group and control group, with 34 undergraduates in each group. The undergraduates in the experimental group received the teaching method of 3D printing in the with flipped classroom, and those in the control group received traditional teaching. The teaching effect was evaluated by questionnaire and examinations of basic knowledge and clinical skills, Independent-samples t test was used for between-group comparison with SPSS 20.0.@*Results@#Compared with the control group, the experimental group had significantly higher scores in theoretical examinations (34.79±2.20 vs. 31.73±3.12, t=4.676, P=0.000) and clinical skill examination (50.06±2.98 vs. 45.82±4.68, t=4.449, P=0.000). The questionnaire survey showed that among the 34 undergraduates in the experimental group, 31(91.2%) thought that the new teaching method could increase their learning interest, 33(97.0%) believed it could improve learning efficiency, 25(73.5%) believed the models obtained by 3D printing had good quality, 32(94.1%) felt that it could improve clinical skills, 28 (82.4%) thought it could enhance the interaction between students and teachers, and 29(85.3%) thought it did not bring extra burden.@*Conclusion@#The teaching method of 3D printing combined with flipped classroom in the practice teaching of otolaryngology-head and neck surgery can improve students' learning interest, academic scores, and clinical skills, and therefore, it holds promise for application in teaching.

Objective To investigate the application of 3D printing in the flipped classroom in the practice teaching of otolaryngology-head and neck surgery. Methods A total of 68 medical undergraduates of the Grade 2013 in Air Force Medical University were divided into experimental group and control group, with 34 undergraduates in each group. The undergraduates in the experimental group received the teaching method of 3D printing in the with flipped classroom , and those in the control group received traditional teaching. The teaching effect was evaluated by questionnaire and examinations of basic knowledge and clinical skills, Independent-samples t test was used for between-group comparison with SPSS 20.0. Results Compared with the control group , the experimental group had significantly higher scores in theoretical examinations (34.79 ±2.20 vs. 31.73 ±3.12, t=4.676, P=0.000) and clinical skill examination (50.06 ±2.98 vs. 45.82 ±4.68, t=4.449, P=0.000). The questionnaire survey showed that among the 34 undergraduates in the experimental group, 31(91.2％) thought that the new teaching method could increase their learning interest, 33 (97.0％) believed it could improve learning efficiency, 25 (73.5％) believed the models obtained by 3D printing had good quality, 32 (94.1％) felt that it could improve clinical skills, 28 (82.4％) thought it could enhance the interaction between students and teachers, and 29(85.3％) thought it did not bring extra burden. Conclusion The teaching method of 3D printing combined with flipped classroom in the practice teaching of otolaryngology-head and neck surgery can improve students' learning interest, academic scores, and clinical skills, and therefore, it holds promise for application in teaching.
ABSTRACT
OBJECTIVE@#To deepen the understanding of chronic subdural hematoma and to seek the effective treatment for chronic subdural hematoma (CSDH).@*METHODS@#We retrospectively reviewed a series of 17 consecutive patients with CSDH, who received the treatment of bone flap craniotomy. To explore the surgical indications for CSDH, the data of imaging appearance, intraoperative findings and postoperative complications were analyzed.@*RESULTS@#Among the patients, 13 were septated CSDH, with the characteristic imaging features such as anti-"3" impression in the inner edge of the hematoma and fibrous strap structure in the hematoma. Four patients were organized CSDH, with strong signals of T1 and T2 as well as hypointense netlike structure within the hematoma cavity while low signal on MRI in the thickened inner membrane. Burr hole trepanation was performed, but no improvement were achieved, whereas the bone flap craniotomy removed the hematoma completely without serious surgical complication except 1 case.@*CONCLUSION@#Based on the preoperative imaging data, flap bone craniotomy seems to be the first choice for treatment of CSDH.
