Objective: We aimed to review the history of anatomical dissection, and to examine how modern educational techniques will change the way temporal bone dissection is taught to otolaryngology trainees.Method: Review of the literature using Medline, Embase and PubMed database searches. Results: Temporal bone anatomy has traditionally been taught using cadaveric specimens. However, resources such as three-dimensional reconstructed models and 'virtual reality' temporal bone simulators have a place in educating the otolaryngology trainee.Conclusion: We should encourage the use of fresh frozen cadaveric temporal bone specimens for future otologists. Artificial three-dimensional models and virtual reality temporal bone simulators can be used to educate junior trainees, thus conserving the scarce resource of cadaveric bones.

Scoliosis is a sideway spinal deformity. If the curvature is measured to be more than 50 degrees, the patient can feel significant discomfort. In such cases, surgery is required to straighten the spine. Pedicle screw insertion is a common procedure for scoliosis surgery.The technique requires the placement of screws from the pedicle into the spine. A rod is used to connect all the pedicle screws. The spine is straightened during the connection process. One of the most common techniques used for pedicle screw insertion is called the free hand technique. During free hand surgery, the surgeon creates a screw channel by manually probe into the spine. The lack of visual aid requires the surgeon to rely strongly on haptics feedback. Due to the spine sensitivity and the limited operating range, small changes in force or direction can cause the probe to breach out of the spine. If the breach reaches the spine medial, the spinal cord could be damaged. Even experienced surgeons can not prevent breach. Studies have found that surgeons with 5 or more years of surgical experience have a breach rate of 10.8 %.In this thesis, pedicle screw insertion simulator is developed and examined in detail. The simulator combines visual and haptics sensation to recreate the channel creation process of the surgery. A 2DOF mechanical device is used for the haptics sensation. The device includes a linear actuator and a rotary motor. The simulator was tuned to four different surgical scenarios by 2 expert surgeons. The scenarios are soft probing, hard probing, lateral breach, and in-out-in breach. 10 additional surgeons were asked to participant in a clinical study. Measurements were collected for analysis. The focus of the study is to find if the surgeon can recognize the simulated breach scenarios. Four research questions were examined, and they are: 1. Can experience help the surgeon improve correct breach recognition rate? 2. Can experience help the surgeon improve overall correct recognition rate? 3. Is there any performance difference between surgeons with different experience iii level? 4. Can the simulation trials become a learning tool for the simulation tasks?Each question has its own null hypothesis and statistical analysis is used to determine if the null hypothesis is rejected. The main conclusion is that there is no statistically significant relationship between the wrong breach or total wrong recognition rate and surgical experience. Furthermore, there is statistically significant in hard probing scenario between surgical experience and vertical force variance. Lastly, ANOVA analysis showed that the breach force and velocity in three trials are close to statistically significant, more data may prove that the simulator can be a training tool for the tasks. Lastly but most importantly, I appropriate his endless knowledge and kind mentorship that helped me completing this thesis.

Introducti on and Aims: Real models and virtual simulators have been used with positive results in several fields of medicine. These new devices can enhance teaching, learning and also training in Otolaryngology, reducing associated costs and potentially reducing medical errors. We reviewed the literature on the real and virtual models and simulators used for education and training in our medical specialty, discussing some of them and the results achieved with such instruments. Moreover, we also discuss the future perspectives in education and training in our medical specialty. Methods: Literature review. Conclusions: Otolaryngology, a clinical and surgical field of medicine, should be at the forefront of this technological revolution. In our specialty, real models and virtual simulators and environments have a great teaching and learning potential. With equipment costs dropping, thanks to technological development, these tools tend to become increasingly more popular.
