Stereotactic Radiosurgery in Guntur: Precision Neurosurgery Without Traditional Surgery

The future of neurosurgery is increasingly defined by precision, safety, and minimally invasive treatment strategies. Among the most transformative innovations in modern neuroscience is Stereotactic Radiosurgery (SRS)—a technology that allows neurosurgeons to treat complex brain disorders without making a single incision.

This topic was recently highlighted by Dr. Mohana Rao Patibandla, Founder and Chief Neurosurgeon of Dr. Rao’s Hospital – International Institute of Neurosciences (IIN), Guntur, during his invited faculty lecture titled “Stereotactic Radiosurgery: What Every Beginner Should Know” at the 5th Annual Young Neurosurgeons Forum Conference (YNFCON 2026) held at The Westin Mumbai Powai Lake.

Addressing young neurosurgeons from across India, Dr. Patibandla shared practical insights into the principles, applications, patient selection, and future of stereotactic radiosurgery, drawing upon his experience of approximately 3,000 stereotactic radiosurgical procedures and extensive international fellowship training in neuro-oncology, skull base surgery, cerebrovascular neurosurgery, endovascular neurosurgery, and functional neurosurgery.

As one of the leading centers for advanced neurosciences care in India, Dr. Rao’s Hospital – International Institute of Neurosciences (IIN) continues to bring world-class neurosurgical innovations to patients across Andhra Pradesh, Telangana, India, and international destinations.

What Is Stereotactic Radiosurgery?

Despite its name, stereotactic radiosurgery is not surgery in the conventional sense.

There are:

No scalp incisions
No craniotomy
No surgical scars
No blood loss
Minimal recovery time

Instead, SRS uses highly focused beams of radiation delivered with submillimeter precision to target abnormal tissue while minimizing radiation exposure to surrounding healthy brain structures.

According to the National Cancer Institute, stereotactic radiosurgery is an advanced form of radiation therapy used to treat tumors and abnormalities in the brain and nervous system.

The principle is simple:

Multiple low-dose radiation beams converge on a precisely identified target. While each beam individually causes minimal tissue exposure, the cumulative dose at the target is powerful enough to stop tumor growth, damage abnormal blood vessels, or interrupt pathological nerve activity.

This is why stereotactic radiosurgery is often described as:

“Surgery without a scalpel.”

Dr. Mohana Rao Patibandla presents “Stereotactic Radiosurgery: What Every Beginner Should Know” during YNFCON 2026 in Mumbai, highlighting the major indications and applications of stereotactic radiosurgery in modern neurosurgical practice.

The Young Neurosurgeons Forum Conference (YNFCON) is one of India’s premier educational platforms for emerging neurosurgeons.

As neurosurgery evolves toward precision-based treatments, young specialists must understand not only traditional microsurgery but also:

Radiosurgery
Endovascular therapy
Neuronavigation
Neuroendoscopy
Functional neurosurgery
Image-guided interventions

During his lecture, Dr. Patibandla emphasized that future neurosurgeons must be capable of selecting the most appropriate treatment rather than simply performing surgery.

A patient with a deep-seated lesion may benefit more from radiosurgery than open surgery.

Similarly, a patient with trigeminal neuralgia may achieve excellent pain relief without requiring a major cranial procedure.

The central message of the lecture was clear:

Good neurosurgeons know how to operate. Great neurosurgeons know when not to operate.

Why Stereotactic Radiosurgery Has Revolutionized Neurosurgery

Dr. Mohana Rao Patibandla discussing brain metastases, AVMs, vestibular schwannomas, meningiomas, trigeminal neuralgia, and pituitary adenomas as key indications for stereotactic radiosurgery.

Over the past several decades, stereotactic radiosurgery has fundamentally changed the treatment of many neurological conditions.

Traditionally, lesions located deep within the brain often required major surgery associated with significant risks.

Today, carefully selected patients can receive treatment with:

Minimal discomfort
Outpatient or short-stay procedures
Rapid return to normal activities
Excellent long-term outcomes

This shift represents one of the most important advancements in modern minimally invasive neurosurgery.

At Dr. Rao’s Hospital, treatment recommendations are based on evidence, imaging findings, lesion characteristics, patient health status, and long-term outcomes rather than a one-size-fits-all approach.

Conditions Treated with Stereotactic Radiosurgery

1. Brain Metastases

Brain metastases represent one of the most common indications for stereotactic radiosurgery worldwide.

Cancer cells from:

Lung cancer
Breast cancer
Kidney cancer
Melanoma
Gastrointestinal cancers

can spread to the brain.

Historically, whole-brain radiation therapy was often used.

Today, stereotactic radiosurgery allows physicians to precisely target metastatic lesions while preserving cognitive function and reducing unnecessary radiation exposure.

For many patients, this approach provides:

Excellent local tumor control
Improved quality of life
Reduced neurocognitive side effects

2. Vestibular Schwannoma (Acoustic Neuroma)

Vestibular schwannomas are benign tumors arising from the vestibular nerve.

Symptoms may include:

Hearing loss
Tinnitus
Dizziness
Balance problems
Facial numbness

Stereotactic radiosurgery is particularly valuable for:

Small tumors
Medium-sized tumors
Elderly patients
Patients unfit for surgery
Residual tumors following microsurgery

Long-term tumor control rates exceed 90% in many published studies.

3. Meningiomas

Meningiomas are among the most common primary brain tumors.

While many can be surgically removed, some tumors are located near critical structures such as:

Optic nerves
Cavernous sinus
Brainstem
Cranial nerves

For these patients, stereotactic radiosurgery offers an excellent treatment option.

It is commonly used for:

Small meningiomas
Recurrent tumors
Residual disease after surgery

4. Arteriovenous Malformations (AVMs)

AVMs are abnormal connections between arteries and veins.

These lesions carry the risk of:

Brain hemorrhage
Seizures
Neurological deficits
Headaches

While microsurgery remains the gold standard for many AVMs, radiosurgery is highly effective for:

Deep AVMs
Eloquent brain AVMs
Small to moderate-sized lesions

The radiation gradually causes obliteration of abnormal vessels over months to years.

Patients with vascular disorders may also benefit from: https://drraoshospitals.com/endovascular-neurosurgery/

5. Trigeminal Neuralgia

Often called the “suicide disease” because of its severe pain, trigeminal neuralgia causes sudden electric shock-like facial pain.

When medications fail, stereotactic radiosurgery can provide significant pain relief by targeting the trigeminal nerve root.

Advantages include:

No incision
Outpatient treatment
Minimal recovery
High patient satisfaction

6. Pituitary Adenomas

Pituitary tumors may require surgery, medication, radiosurgery, or a combination of treatments.
