Visualization of Intraparotid Facial Nerve and Tumor Relationship: Feasibility and Accuracy Assessment

Puntos clave

CISS imaging revealed 91.4% accuracy in locating parotid tumors and assessing their compression on the facial nerve.
Concordance between CISS results and surgical findings was excellent, with a Kappa value of 0.96.
The study highlights the significance of understanding tumor and nerve relationships for risk reduction in surgery.
CISS sequences provide valuable preoperative insights to minimize facial nerve injury during parotid surgeries.

Resumen

Motivation: Determining the degree of compression of the intraparotid facial nerve by the parotid tumor is helpful in formulating preoperative planning. Goal(s): To assess the degree of compression exerted by the tumor on the IFN with a constructive interference in steady-state (CISS) sequence. Approach: CISS sequences were used to determine the location of parotid tumors and their contact with the facial nerve. Results: The accuracy of CISS images in determining tumor location was found to be 91.4%. Furthermore, CISS images demonstrated excellent concordance with surgical results (Κ = 0.96) in evaluating the extent of tumor compression on nerves. Impact: The CISS sequence improves the accuracy of parotid tumor localization and is reliable in assessing the relationship between the tumor and the facial nerve; knowing this relationship helps reduce the risk of facial nerve injury during surgery.
