Objective To evaluate the effect of step teaching combined with precisely procedural operation training mode in the standardized training of otolaryngology technology for residents.Methods From January 2017 to December 2018,38 residents in the otolaryngology department of the First Affiliated Hospital of Sun Yat-sen University were selected as the research objects.They were trained for one year by using step teaching and precisely procedural operation training mode.After the training,questionnaire survey method and theory and skill examination were used to compare the training effect.Results All residents passed the examination of theory and skill,and the excellent rate of otoendoscopy skill operation was 81.6% (31/38).The results of questionnaire survey showed that 100.0% (38/38) of residents were satisfied with this teaching mode,100.0% (38/38) of residents thought that their interest in learning and their proficiency in otoendoscopy operation had been greatly improved;86.8% (33/38) of residents thought that their ability of otoendoscopy operation had been greatly improved;92.1% (35/38) of residents thought that their ability of intraoperative response had been greatly improved,89.5% (34/38) residents considered that the communication ability between doctors and patients had been greatly improved.Conclusions The combination of step teaching and precisely procedural operation training is helpful to improve the training effect of otoendoscopy technology and is suitable for the standardized training of otoendoscopy technology for residents.
