Background: Safe resection of skull base and nerve sheath tumors demands maximal precision to preserve critical neurovascular structures. Conventional continuous mode ultrasonic aspirators, such as the Stryker Sonopet Classic, deliver unmodulated energy that may result in suboptimal tissue selectivity and increased collateral trauma.
Objective: To evaluate the safety, usability, and effectiveness of the Sonopet iQ Pulse Control system through surgeon-reported outcomes and postoperative video analysis.
Methods: Two neurosurgeons performed resections of skull base tumors utilizing the Sonopet Pulse Control system. Postoperative surveys assessing seven operative parameters (control, precision, ease of use, visibility, haptic feedback, efficiency, and selectivity) were completed after each case. Postoperative video analysis was performed independently to evaluate critical structure preservation and operative efficiency.
Results: Across six resections, surgeons rated Sonopet Pulse Control highly in all domains, with average scores ranging from 7.7 to 9.0 on a 10-point scale. Video analysis confirmed 100% preservation of critical structures across all cases. Sonopet Pulse Control demonstrated consistent performance across diverse tumor types and surgical approaches.
Conclusion: Pulse-controlled ultrasonic aspiration with Sonopet iQ enhances surgical precision, improves tissue selectivity, and preserves critical structures during skull base tumor resections. These findings support the safety and usability of Sonopet Pulse Control in complex cranial surgery
