What is Endoscopic Brain Surgery?

At Rebound, our multidisciplinary neurosurgery team is equipped with the latest technologies available to treat a variety of conditions that affect the brain, including tumors and lesions.

Rebound neurosurgeon Dr. Ashok Modha explains endoscopic brain surgery, how it is used to treat the brain, and what risks and benefits patients should consider.

What is Endoscopic Brain Surgery?

Endoscopic brain surgery is a procedure used primarily to treat brain tumors. It is considered a minimally invasive brain surgery that allows neurosurgeons to identify and treat conditions that are deep within the brain.

“This type of surgery allows us to treat brain tumors less invasively than traditional open brain surgery, while still affording us the ability to get an in-depth view of the brain,” says Dr. Modha.

During this procedure, thin tubing that transmits video images of the brain is inserted through one or two small incisions in the skull or through an opening in the body. This tube-like instrument, called an endoscope, contains a small camera that allows the neurosurgeon to see detailed images of the problem area in the brain.

“Endoscopic approaches have truly transformed how we treat tumors, particularly because endoscopic techniques give us such a clear visualization of the tumor,” says Dr. Modha. “This approach also does not always require us to access the brain through the skull. We’re able to access the brain through pathways like the nose and sinuses as well.”

The neurosurgeon will use the images transmitted by the endoscope as a guide for removing the tumor or repair the affected area of the patient’s brain. The removal of the tumor or damaged area is performed with specialized surgical instruments.

What Risks are Associated with Endoscopic Brain Surgery?

With any surgery, there are risks involved. Rebound surgeons educate their patients on the best treatment options for their particular condition and communicate the potential risks.

Possible risks:

  • Temporary or permanent interference with sensory and motor functions like speech, vision, memory, balance, coordination, etc.
  • Blood clot
  • Bleeding
  • Swelling
  • Infection
  • Seizure
  • Stroke
  • Coma

“While the likelihood of a patient experiencing these complications is rare, we believe in strong patient-doctor communication, so each patient understands their procedure and the risks associated,” says Dr. Modha.

What are the Benefits of Endoscopic Brain Surgery?

“Endoscopic brain surgery offers many benefits to patients,” says Dr. Modha. “This type of surgery is less invasive than other open surgery procedures, offering a faster recovery period and less pain for the patient.”

While each patient’s medical history, age, condition and other factors play a role in the outcome of endoscopic brain surgery, here are some of common benefits associated with the procedure:

  • Minimally invasive (results in less pain for the patient)
  • Faster recovery time than open brain surgery
  • Reduced risk of brain trauma
  • Reduced risk of side effects
  • Reduced hospital stay
