Summary of Intraoperative Ultrasonography in Vestibular Schwannoma Surgery
New Information: The study introduces a 4-step protocol for integrating intraoperative ultrasonography (ioUS) into the surgical workflow for resecting vestibular schwannomas (VS), a practice not widely reported in literature.
Importance: ioUS could enhance the safety and efficacy of VS surgery by providing real-time imaging, which aids in identifying the tumor and relevant anatomical structures, assessing the extent of tumor removal, and confirming the surgical outcome before closure.
Contribution to Literature: This study contributes by detailing a specific, replicable ioUS protocol and demonstrating its potential benefits through illustrative cases. It suggests that ioUS is a cost-effective and user-friendly tool that could potentially reduce complications and improve patient outcomes in VS surgery.
Results: The study found that ioUS is effective for transdural identification of VS, intradural estimation of tumor debulking, and transdural postclosure visualization of the surgical site. However, the impact of ioUS on clinical outcomes, operative time, and complication rates requires further validation.
