Objective: The aim of the study is to cover the shortages of PBL, such as time-consuming, abstract, lacking of the course of clinic practice, and to introduce PBL to the teaching of otorhinolaryngology.
Method: By the improvement of the international classic teaching model of PBL, we put forward "four-stage gradual expanding approach of PBL" and establish "four-stage gradual expanding approach of PBL in otorhinolaryngology".
Result: Through the four stages of watching PBL, simulation PBL, internship PBL, practice PBL, we have accomplished the organic integration of theory teaching and clinical practice.
Conclusion: This teaching method is more adaptive to the teaching of otorhinolaryngology, and it can help the medicine students to establish the whole concept of medicine and can stimulate them to form the good habits of self-regulated learning and life-long learning efficiently.
