Summary
This study introduces a new framework for surgeons to reliably identify the facial nerve trunk (CNVII) during parotidectomy. This method enhances surgical accuracy and reduces the risk of nerve injury.
Area of Science:
- Surgical Anatomy
- Neurosurgery
- Head and Neck Surgery
Background:
- Current literature and textbooks inadequately address challenges in identifying the facial nerve trunk (CNVII) during parotidectomy.
- This gap can lead to deficits in surgical training and potential complications.
Purpose of the Study:
- To present a novel framework for reliable identification of the facial nerve trunk (CNVII) after skull base exit during parotidectomy.
- To provide residents and practitioners with a surgically relevant method for CNVII localization.
Main Methods:
- Developed an approach integrating multiplanar intersections (based on mathematical principles) with surgical anatomy.
- Utilized medical illustrations and surgical photography to demonstrate the method.
Main Results:
- The multiplanar intersections facilitate the application of the triangulation concept for improved accuracy and efficiency in CNVII localization.
- Demonstrated improved surgical localization of the facial nerve trunk (CNVII).
Conclusions:
- Integrating multiplanar localization with surgical anatomy offers a reliable method for consistent and rapid CNVII identification.
- This approach inherently reduces the risk of inadvertent injury to the facial nerve trunk (CNVII).
