How close are we to anterior robotic skull base surgery?

PURPOSE OF REVIEW

The application of robotic surgery to anterior skull base disease has yet to be defined despite the potential for improved tumour resection with less morbidity in this region. Complex anatomy and restricted access have limited the development of robotic anterior skull base surgery.

RECENT FINDINGS

A limited number of transoral robotic surgical anterior skull base procedures have been undertaken; however, there are significant limitations to the utilization of this technology in the anterior skull base. In this article, the advantages, disadvantages and limitations of robotic anterior skull base surgery are discussed. Currently, the major limitation is the size of the robotic endoscope and of the available instrumentation. Technological advancements that provide promise for the future development of robotic anterior skull base surgery are in development, such as single-port robots, flexible instrument systems and miniaturization and growth of minimally invasive platforms.

SUMMARY

Although transnasal access to the skull base is not possible with the currently available robotic systems, promising technology does exist and is in development. Robotic anterior skull base surgery promises to provide greater access to skull base disease, improve oncologic results, reduce morbidity and to reduce the ergonomic burden on the surgeon.
