Summary
Instrument navigation in otolaryngology (ENT) enhances intraoperative orientation and can reduce operating time by up to 10%. While beneficial for skull base surgery, further scientific data and surgeon familiarity are needed.
Area of Science:
- Otolaryngology
- Medical Technology
- Surgical Navigation
Context:
- Instrument navigation, introduced by Schloendorff, is established in otolaryngology (ENT) for improved intraoperative orientation.
- Opto-electric and electromagnetic navigation principles are sophisticated methods for intraoperative position recognition.
- Approximately 30% of German ENT hospitals possess navigation systems, primarily used for functional endoscopic sinus surgery (FESS).
Purpose:
- To evaluate the impact and current limitations of instrument navigation in ENT, particularly in frontal skull base surgery.
- To assess the benefits and challenges associated with adopting navigation systems in clinical practice.
Summary:
- Surgeons predominantly view instrument navigation positively, citing potential operating time savings of up to 10%.
- Extended frontal skull base approaches show significant benefit from navigation support, though robust scientific data are limited.
- Current limitations include an accuracy of approximately 2 mm and simple planar sectional view information representation.
Impact:
- Instrument navigation offers substantial benefits for complex procedures like frontal skull base surgery.
- Increased utilization, even in less complex cases, is recommended to build surgeon familiarity and proficiency.
- Further research is needed to validate the efficacy and refine the application of navigation systems in ENT surgery.
