Background: Tremor plays an important role in microsurgery, especially in stapes surgery because of the minute size and vulnerability of the middle ear structures. The apparent learning curve in stapes surgery suggests better outcomes after more practise. Earlier studies in the otolaryngology field about the effect of microsurgical experience on tremor suggest a trend towards better results in expert groups but the difference did not reach significance level. However, group sizes were small. Because of the declining number of stapes surgery cases and the complexity of stapes surgery, a wide variety of models have been developed to practise the stapes operation. Earlier studies suggest the benefits of these models and also a possible learning curve in stapes models. This study aims to validate whether microsurgical experience and microsurgical practise have beneficial effects on tremor. Methods: 86 subjects were divided in 3 levels of microsurgical experience and their tremor was measured on a tremor model. Differences of tremor outcomes between the 3 levels were analysed. 37 subjects with no microsurgical experienced trained on a stapes model for three times. Tremor measurements before and after training were compared. Results: No differences in tremor outcomes were found between the 3 levels of experience. Microsurgeons with stapes surgery experience did have lower tremor values. Training on a stapes model lowered tremor values down to the same level as experienced stapes surgeons. Conclusions: Microsurgical experience does not seem to be of influence on tremor outcomes. However, experience with stapes surgery does seem to decrease tremor values. Because only 6 surgeons with stapedotomy experience were included it is suggested to measure the tremor of more microsurgeons with stapedotomy experience. Practising on the used stapes model decreases tremor values significantly down to the same level as stapes surgeons. This suggests that the stapes model used is a good tool for practising stapes surgery on.
