The next generation of navigational technology.

Registration for image guidance has become significantly simplified and will continue to improve in accuracy. Unparalleled visualization of target tissues has been made possible through advances in imaging technologies,some of which have been modified to be employed directly in the operating room. With the advent of functional imaging techniques, the promise of functional rather than structural imaging suggests potentially fascinating interventions based on functional disturbances in tissue. Given the aggressive nature of the technology industry, some of the issues in surgical navigation discussed in this article have probably already been resolved and may be on their way to market. Undoubtedly, other points will also soon be addressed in novel and imaginative ways. As a result, the authors hope, the practice of rhinology will continue to evolve to improve the standard of care for patients. The future of many therapeutic interventions seems to be tied to the information infrastructure provided by information-guided therapy. Only through the innovative use of information-guided technology will further minimization of risks and maximization of benefit be achieved.
