Study on the influence of Barbecure combined with Epley on residual dizziness of horizontal canal benign paroxysmal positional vertigo by SRM-vertigo diagnosis system / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the influence of Barbecure combined with Epley on residual dizziness of horizontal canal benign paroxysmal positional vertigo（HC-BPPV） by SRM-vertigo diagnosis system. Methods:A total of 406 patients diagnosed with HC-BPPV from Nov 2021 to Nov 2022 were enrolled by rapid axial roll test and Dix-Hallpike in the department of Otorhinolaryngology Head and Neck Surgery, the First Affiliated Hospital of Xi'an Jiaotong University. The patients were divided into two groups by hospital card numbers, in which the numbers that were odd were considered as group A, and the numbers that were even were considered as group B. The group A underwent two circles of Barbecure repositioning procedure by SRM-vertigo diagnosis system, while the group B underwent two circles Barbecure combined with Epley repositioning procedure by SRM-vertigo diagnosis system. The treatment was stopped on the next day when two groups of patients were cured, and those who were not cured will continue treatment with the same method. Results:The cure rate of group A was 83.41%, and the cure rate of group B was 80.51%, the difference between the two groups was not-statistically significant difference（P>0.05）. The rate of residual dizziness of group A was 23.30%, the rate of residual dizziness of group B was 11.46%, the difference between the two groups was statistically significant（P<0.05）. Conclusion:The Barbecure combined with Epley otoliths repositioning maneuver by SRM-vertigo diagnosis system can significantly reduce the rate of residual dizziness after the treatment of HC-BPPV, and improve the quality of life of patients.

Application of 3D printing in the flipped classroom in practice teaching of otolaryngology-head and neck surgery / 中华医学教育探索杂志

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.

Clinical analysis of bone flap craniotomy for 17 patients with chronic subdural hematomas / 中南大学学报(医学版)

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.
