Background And Objectives:
Despite growing interest in neuroendoscopy, endoscopic resection of intraventricular and paraventricular brain tumors is still hindered by a lack of appropriate instrumentation. The Söring ultrasonic aspirator holds significant promise but is limited because of its original design allowing sole use with the GAAB® endoscope.
Methods:
A simple modification of the ultrasonic aspirator which allows use down multiple endoscopes is described along with surgical outcomes in the context of the largest reported case series of 58 procedures in 52 patients, thus further expanding its applications and versatility.
Results:
Our modification enabled the use of the Söring ultrasonic aspirator with the MINOP® InVent neuroendoscope, facilitating tumor resection in 58 procedures of 52 patients between July 2015 and June 2022. Near-total to gross-total resection was achieved in 30.8% of cases, with no permanent neurological deficits observed. The modified aspirator proved effective and safe, with no adverse events related to its use.
Conclusion:
The Söring ultrasonic aspirator represents a significant landmark in neuroendoscopic surgery. Our modification allowed greater versatility and compatibility with multiple endoscopes. This safe and effective modification will broaden its use and with time will have a considerable impact in the field of minimally invasive neurosurgery.
