Introduction: Welcome to the presentation on the use of ultrasonic aspirator in surgery for spinal cord tumors, specifically focusing on ependymomas

What is ependymoma?

Definition: Ependymoma is a type of brain or spinal cord tumor that arises from ependymal cells.
Location: Ependymomas can occur at various levels of the spinal cord, including cervical, thoracic, and lumbar regions.
Characteristics: Ependymomas are typically slow-growing tumors that can compress the spinal cord, causing neurological symptoms.

Ultrasonic Aspirator Overview

Definition: An ultrasonic aspirator is a surgical tool that uses ultrasonic energy to fragment and remove tumor tissue.
Function: Ultrasonic aspirators break down tumor tissue into smaller pieces, which can be aspirated or suctioned out.
Benefits: Ultrasonic aspirators offer precise tissue removal, tissue preservation, hemostasis, and can be used in minimally invasive approaches.

Tumor Resection

Importance: Ultrasonic aspirators are effective in debulking or removing tumor tissue from the spinal cord.
Technique: Ultrasonic energy emitted by the aspirator helps to break down the tumor, allowing for precise removal while minimizing damage to healthy tissue.
Hemostasis: Ultrasonic aspirators provide coagulation of blood vessels, which helps control bleeding during surgery.

Tissue Preservation

Importance: Preservation of normal tissue and neural structures is crucial in spinal cord tumor surgery.
Selectivity: Ultrasonic aspirators selectively target and remove tumor tissue while preserving normal healthy tissue.
Patient Outcomes: Tissue preservation helps minimize postoperative complications and optimize patient outcomes.


Importance: Precise tissue removal is critical in spinal cord surgery to avoid damage to surrounding structures.
Controlled Approach: Ultrasonic aspirators provide controlled tissue removal, allowing surgeons to precisely remove tumor tissue while minimizing the risk of complications.
Improved Visibility: Precise removal of tumor tissue improves visibility for the surgeon, facilitating safe and effective tumor resection.

Minimally Invasive Approach

Benefits: Ultrasonic aspirators can be used in minimally invasive spinal surgery, such as endoscopic or keyhole approaches.
Reduced Trauma: Minimally invasive approaches result in smaller incisions, reduced tissue trauma, and faster recovery times compared to traditional open surgery.
Versatility: Ultrasonic aspirators are versatile and can be used in various surgical approaches, making them suitable for different types of spinal cord tumors, including ependymomas.

Safety Considerations

Expertise: The use of ultrasonic aspirators should be performed by experienced surgeons who are well-versed in their appropriate usage and safety precautions.
Patient Selection: Patient selection should be carefully considered to ensure optimal outcomes and minimize risks.
Follow-up Care: Proper postoperative care and monitoring are essential for patient recovery and long-term outcomes.


Ultrasonic aspirators are valuable tools in spinal cord tumor surgery, including for ependymomas, providing precise tumor resection, tissue preservation, hemostasis, and versatility.
