Minimally Invasive & Full Endoscopic NeurosurgeryHyderabad's only Germany-trained endoscopic neurosurgeon
Dr. Sayuj Krishnan performs the full spectrum of minimally invasive neurosurgery — from 6 mm endoscopic spine procedures with same-day discharge to ROSA robotic DBS and awake craniotomy for brain surgery — at Yashoda Hospital, Malakpet.
What Is Full Endoscopic Neurosurgery?
Full endoscopic neurosurgery replaces the surgeon's eye and microscope with a 4K endoscope camera passed through a 6–8 mm working channel. Unlike "keyhole" or standard MIS surgery — which still require muscle-spreading retractors — the full endoscopic technique operates through a single thin tube under continuous fluid irrigation, without cutting any muscle.
The result: less blood loss (often <10 ml), no drain, minimal post-operative pain, and same-day discharge for most spine cases. For eligible patients, it represents the least invasive spinal surgery available today.
For brain surgery, "minimally invasive" means different things at different anatomical targets — from a 2 cm port-based tumor resection to ROSA-guided DBS electrode placement with sub-millimetre accuracy to awake craniotomy for eloquent-cortex tumors. Dr. Sayuj practices all of these at Yashoda Hospital, Malakpet.
Trained Where the Technique Was Born
Full endoscopic spine surgery was developed and commercialised in Germany — TESSYS by Joimax (Karlsruhe) and the Wolf endoscopic system by Richard Wolf GmbH. Dr. Sayuj Krishnan completed a structured surgical fellowship in full-endoscopic spine surgery at a leading German centre, learning directly from the surgeons who pioneered the modern technique.
This is not an "observership" (watching from the gallery) or a weekend workshop. It was a hands-on fellowship with supervised operative cases, cadaveric training, and proctored live surgery — the same training pathway used by European endoscopic spine surgeons.
Dr. Sayuj is the only neurosurgeon in Hyderabad with a Germany-based endoscopic spine surgical fellowship — verifiable via LinkedIn and Yashoda Hospital profile.

Learn more →MIS TLIF (Minimally Invasive Fusion)
For cases requiring spinal stabilisation — pedicle screws and cage placed through 15 mm stab incisions with fluoroscopy or navigation guidance.
Learn more →Awake Spine Surgery
Endoscopic spine procedures under local anaesthesia + conscious sedation — eliminating general anaesthesia risk entirely for high-risk patients.
Learn more →Minimally Invasive Brain Surgery
Endoscopic, robotic, and awake approaches — matched to anatomy, not habit.
Endoscopic Brain Tumor Resection
Tubular port-based resection of deep-seated brain tumors (thalamic, basal ganglia, ventricular) guided by neuronavigation — 2 cm scalp incision.
Learn more →Awake Craniotomy
Resection of tumors adjacent to motor, speech, or sensory cortex with the patient awake — maximizing safe resection while preserving function.
Learn more →ROSA Robotic DBS
Sub-millimetre electrode placement for Parkinson's DBS using ROSA robotic guidance — the most precise DBS implantation available in Hyderabad.
Learn more →Endoscopic Pituitary Surgery
Transsphenoidal endoscopic approach for pituitary adenomas and sellar lesions — no external incision, nasal approach only.
Learn more →Endoscopic Third Ventriculostomy (ETV)
Endoscopic management of obstructive hydrocephalus — an internal bypass that avoids shunt implantation in suitable cases.
Learn more →Microvascular Decompression (MVD)
Microsurgical decompression of the trigeminal or facial nerve for neuralgia — 90%+ long-term pain-free outcomes.

6 mm incision — smaller than a pencil eraser
The entire endoscopic spine procedure happens through a working channel smaller than a standard pencil eraser. No muscle cutting, no sutures in most cases — just a waterproof dressing.
Germany-trained: where the technique was invented
Full endoscopic spine surgery was developed and refined in Germany (TESSYS by Joimax, Wolf systems). Dr. Sayuj trained at the source — not an observership, a structured surgical fellowship.
Same-day discharge for most spine cases
Most endoscopic lumbar discectomy patients walk out of hospital the same day. No ICU, no long nursing stay, no prolonged physiotherapy programme before discharge.
ROSA robotics for brain precision
For DBS and complex brain cases, ROSA robotic assistance delivers sub-millimetre electrode targeting — the same technology used in leading European and US neurosurgical centres.
Transparent pricing, cashless insurance
Written cost estimates before surgery. Cashless insurance for all major TPAs. No bill surprises — every procedure has a defined scope-of-work.
Direct surgeon access — not a call centre
Dr. Sayuj personally responds to WhatsApp and tele-follow-up. You consult the surgeon, you are operated on by the same surgeon, and you follow up with the same surgeon.
Am I a Candidate for Endoscopic Surgery?
Endoscopic surgery is appropriate for most single-level disc herniations and focal stenosis — but not for every spine problem. A proper clinical assessment with MRI review is required before confirming candidacy. Use our symptom checker for an initial indication, then book a consultation for a definitive answer.
Good candidates (usually)
- ✓ Lumbar disc herniation with leg pain (sciatica)
- ✓ Cervical disc herniation with arm pain or numbness
- ✓ Lumbar spinal stenosis causing claudication
- ✓ Foraminal stenosis at one or two levels
- ✓ Recurrent disc herniation after previous open surgery
- ✓ High-risk patients (elderly, diabetic, obese) where GA risk is high
Better served by fusion or open surgery
- ✗ Severe spinal instability or spondylolisthesis (Grade 2+)
- ✗ Major deformity (scoliosis requiring correction)
- ✗ Multi-level disease needing reconstruction
- ✗ Prior instrumented fusion at same level
- ✗ Tumors requiring wide resection margins
- ✗ Some cases of significant canal compromise with myelopathy
Frequently Asked Questions
What makes full endoscopic neurosurgery different from keyhole or MIS surgery?
Traditional "keyhole" or MIS surgery uses a small skin incision but still requires muscle spreading with tubular retractors to create a working channel. Full endoscopic surgery goes further — the entire procedure is performed through a 6–8 mm diameter working cannula under continuous fluid irrigation, using a 4K endoscope instead of a microscope. This means zero muscle cutting, minimal blood loss, and same-day discharge in most cases — not typically possible with standard MIS approaches.
Where did Dr. Sayuj receive his full-endoscopic training?
Dr. Sayuj Krishnan completed a dedicated fellowship in Full Endoscopic Spine Surgery in Germany — the country where the TESSYS and TESS systems (the gold-standard endoscopic platforms) were developed by Richard Wolf and Joimax. This is the only such Germany-based endoscopic fellowship held by a practicing neurosurgeon in Hyderabad.
Which spine conditions can be treated with full endoscopic surgery?
Endoscopic techniques are suitable for lumbar disc herniation (slip disc), cervical disc herniation, lumbar spinal stenosis, foraminal stenosis, thoracic disc herniation, far-lateral disc herniations, and recurrent disc herniations after previous surgery. Not all patients are candidates — cases with severe instability, significant deformity, or multi-level disease requiring fusion are better served with MIS fusion approaches.
Is endoscopic neurosurgery available for brain surgery too?
Yes. Minimally invasive approaches for brain surgery include: endoscopic port-based resection of deep brain tumors (neuronavigation-guided), endoscopic third ventriculostomy (ETV) for hydrocephalus, endoscopic pituitary surgery (transsphenoidal approach), and awake craniotomy for tumors near eloquent cortex. ROSA robotic assistance is used for Deep Brain Stimulation electrode placement with sub-millimetre accuracy.
How does same-day discharge work? Is it safe?
For endoscopic lumbar discectomy, patients are anaesthetised with either general anaesthesia (30–40 min procedure) or local anaesthesia + sedation. By 2 hours post-op, most patients are walking with physiotherapy support. Pain is managed with oral NSAIDs. Discharge safety checks include neurological exam, wound inspection, and VAS pain score below 4. Patients are given a 24/7 contact number and a tele-follow-up at 48 hours. In 10+ years of endoscopic practice, readmission rates for same-day discharge patients remain below 1%.
Does health insurance cover endoscopic neurosurgery in Hyderabad?
Yes. All major health insurance providers cover endoscopic spine surgery and minimally invasive brain procedures under the neurosurgery benefit. Cashless facility is available at Yashoda Hospital, Malakpet for empanelled TPAs and corporate policies. Our insurance desk handles pre-authorisation and claim documentation so patients can focus entirely on recovery.
