三维影像处理结合影像导航技术在进修医生鼻科围手术期教学中的应用

目的 研究三维影像处理结合影像导航技术在进修医生鼻科围手术期带教中的应用价值。 方法 回顾性分析2014年1月-2020年12月在西京医院耳鼻咽喉头颈外科鼻科组接受培训的55名进修医生的相关资料,25人采用传统的教学方法(A组),30人采用三维影像处理结合影像导航技术教学方法(B组),4个月鼻科轮转结束后进行教学结果考核。分别以问卷调查的形式评估进修医生对教学方法的满意程度,以及理论考核的形式评估学生对相关知识掌握的程度。 结果 一般资料分析中,两组进修医生年龄差异有统计学意义(P=0.011),从事专业年限、性别、学历等一般情况差异无统计学意义(P=0.092,P=0.584,P=0.783)。教学满意度方面,B组与A组相比,在疾病认识的提高方面差异无统计学意义(P=0.234),在手术理解力的提高、解剖辨识力的提高,以及教学满意度的提高方面,B组均优于A组(P<0.001)。理论考核方面,B组的考核成绩优于A组(P=0.004)。而最终依据多元线性回归分析结果,教学方法的改进对成绩的提高是主要的影响因素。 结论 三维影像处理结合影像导航技术可以帮助进修医生在鼻科围手术期建立三维空间解剖结构,迅速地理解和掌握较为复杂的手术径路,有助于教学质量的提高。

Application of three-dimensional image processing combined with image navigation technology in perioperative teaching of advanced doctors in rhinology

Objective To study the value of three-dimensional image processing technologr combined with image navigation technology in the perioperative teaching of advanced doctors in rhinology. Methods The data of 55 advanced doctors in the Department of Otolaryngology-Head and Neck Surgery of Xijing Hospital from January 2014 to December 2020 was retrospectively analyzed. 25 doctors received traditional teaching methods(Group A)and 30 doctors received three-dimensional image processing technology combined with image navigation technology teaching methods(Group B). The teaching results were evaluated after four months. The satisfaction with teaching methods is evaluated in the form of questionnaire survey, and the condition of relevant knowledge mastering is evaluated in the form of theoretical test. Results In the general condition analysis, there is a statistical difference in the age data(P=0.011), but there is no significant difference in professional time, gender and educational background between the two groups(P=0.092,P=0.584,P=0.783). In the teaching satisfaction assessment, there is no significant difference in the improvement of disease recognization between the two groups(P=0.234). But in the improvement of surgical understanding, anatomical identification and teaching satisfaction, Group B is better than Group A(P<0.001). In the theoretical test, the results of the Group B are better than thoseof Group A(P=0.004). Finally, according to the multiple linear regression analysis, the teaching method changing is the main influencing factor of the improvement in evaluation results. Conclusion For advanced doctors in rhinology, three-dimensional image processing technology combined with image navigation technology can effectively help them establish three-dimensional anatomical structure, understand and quickly master more complicatied surgical approaches.Then the teaching quality will be improved.
