AB  - BACKGROUND: We verified the effectiveness of training in endoscopic endonasal 
      transsphenoidal surgery (eETSS) techniques using chicken eggs and a skull model. 
      METHODS: We verified the area of eggshell removed by drilling when five residents 
      and four experts used the chicken eggs and a skull model. RESULTS: When residents 
      performed drilling on 10 eggs, a mean (+/- standard deviation [SD]) area of 31.2 +/- 
      17.5 mm2 was removed from the first egg, and 104.8 +/- 3.3 mm2 from the tenth and 
      final egg, representing an increase in area and a decrease in SD. The experts 
      performed the same drilling operation on a single egg, and removed a mean area of 
      257+/- 31.7 mm2. These results demonstrated that skills improved as a result of 
      this training, and suggested that this method was also capable of overcoming the 
      initial individual differences in the amount of force applied and ability. An 
      obvious difference between residents and experts was seen in the area removed (p 
      = 0.00011); however, this was attributed to differences in endoscopic 
      manipulation, rather than drilling skill. CONCLUSION: Our findings suggest that 
      this training method could be adequate for acquiring eETSS techniques. Although 
      experts showed superior endoscopic manipulation, residents may also be able to 
      acquire adequate endoscopic skills through further training, and our training 
      method appears to offer an effective means of improving eETSS techniques.
