Table 1 Advantages and disadvantages of the stereotactic systems
conventional stereotactic frames including an aiming arm device | Patient-individually manufactured stereotactic platforms |
|---|---|
+ high stiffness + variable use + recognized state of the art | + low mass (platform about 250 g) + few individual components + easy to operate + platform as a single-use product ◊ no further sterilization processes |
– large dimensions – large weight ◊ high discomfort to the patient – patient fixation to the operating table – very complex, many individual components – long training periods – effort and costs for maintenance – space for storage required – need to be reset for each target point | – can be used only for the two defined target points – long delivery times due to production in USA and subsequent delivery including import control (up to 3 weeks) ◊ daily clinic routine difficult to plan – Assembly of the feed units ◊ time-consuming, source of errors – low acceptance among neurosurgeons |
