Comprehensive Services
The multidisciplinary neurosciences team of SIMS provides advanced, personalised care across the full spectrum of neurological disorders, combining innovative treatment with compassionate support at every stage of recovery.
Vestibular Schwannoma Surgery
- SIMS ranks among India's highest-volume centres for Vestibular Schwannoma surgeries, achieving an exceptional facial nerve preservation rate of over 90% through Facial MEP-guided intraoperative monitoring.
- We also specialise in the management of complex Koos Grade IV Vestibular Schwannomas with significant cerebellopontine angle involvement, delivering precision-led surgery and comprehensive perioperative care for optimal patient outcomes.
Endoscopic Skull Base Surgery
- Our team routinely manages highly complex skull base tumours that were once considered inoperable using advanced minimally invasive endoscopic techniques.
- Annually Performing 100+ procedures, including multi-stage tumour resections, CSF leak repairs and orbital procedures, we combine extensive surgical experience with image-guided navigation to maximise precision and patient safety.
Pituitary & Sellar Region Surgery
- The pituitary surgery program at SIMS handles 60 to 70 cases each year using endoscopic transsphenoidal surgery including pituitary adenomas, craniopharyngiomas, and other sellar and parasellar lesions.
- At SIMS, patients benefit from a team experienced in managing all types of pituitary issues.
Hemifacial Spasm & Trigeminal Neuralgia, Microvascular Decompression (MVD)
- SIMS is the pioneer centre for awake MVD in India, the first of its kind in the country.
- For patients who have lived with the distressing symptoms of hemifacial spasm or trigeminal neuralgia, this procedure offers the possibility of a genuine, lasting surgical cure.
Awake Craniotomy & Brain Mapping
- When a tumour sits close to the areas of the brain responsible for movement, speech, or memory, removing it safely requires more than surgical skill, it requires the patient to be awake and communicating during surgery.
- SIMS has the expertise, the team, and the experience to perform awake craniotomy with intraoperative cortical and subcortical mapping safely and effectively.
Cerebrovascular & Moyamoya Surgery
- From brain aneurysm clipping and AVM surgery to the highly specialised STA-MCA bypass for Moyamoya disease, the cerebrovascular surgery programme at SIMS handles some of the most technically demanding procedures in neurosurgery.
- Patients with rare and complex cerebrovascular conditions are referred here from across India and internationally.
Image-Guided & Neuronavigational Surgery
- Advanced neuronavigation systems give SIMS surgeons real-time anatomical guidance during tumour resection, skull base surgery, and biopsy procedures, maximising surgical precision and minimising the risk of unintended injury to surrounding structures.
5-ALA Fluorescence-Guided Glioma Surgery
- For patients with high-grade gliomas, every millimetre of tumour removed matters.
- SIMS uses 5-aminolevulinic acid (5-ALA) fluorescence technology to make tumour tissue glow under surgical lighting, helping surgeons achieve the most complete resection possible while protecting healthy brain.
Endoscopic Spine Surgery
- Minimally invasive endoscopic spine surgery at SIMS offers patients with disc herniations, spinal stenosis, and spinal tumours an effective surgical option with smaller incisions, less post-operative pain, and a much faster return to normal life compared to conventional open spine surgery.
Complex Paediatric Neurosurgery
- Children with brain tumours, hydrocephalus, spinal cord malformations, and craniosynostosis need specialists who understand not just neurosurgery, but understands their unique vulnerabilities and developmental needs.
- SIMS has a dedicated paediatric neurosurgery programme that treats every child with the expertise and gentleness they deserve.
Deep Brain Stimulation (DBS) & Epilepsy Surgery
- For patients with Parkinson's disease or refractory epilepsy who has not responded adequately to medication, DBS & Epilepsy Surgery can be life changing.
- The functional neurosurgery programme at SIMS offers DBS for movement disorders and surgical epilepsy treatment, supported by the 128-channel video EEG monitoring unit for precise pre-surgical planning.
Comprehensive Stroke Programme
- Stroke is a medical emergency where every minute of delay costs brain tissue. At SIMS, we run a 24/7 acute stroke programme with emergency protocols, RapidAI-powered automated imaging analysis for instant treatment decision support, thrombolysis, and mechanical thrombectomy ensuring the fastest possible time from door to treatment for every stroke patient.
Interventional Neurology & Endovascular Surgery
- Not every brain condition requires an open surgery. Therefore, SIMS offers the full range of endovascular neurology services including mechanical thrombectomy, coil embolisation, flow diversion, and the WEB Device (Woven EndoBridge) for intracranial aneurysm treatment giving patients less invasive, equally effective alternatives for complex neurovascular conditions.
Epilepsy Monitoring Unit
- Living with uncontrolled seizures is exhausting and frightening. The SIMS 128-channel video EEG epilepsy monitoring unit precisely localises seizure activity, enables detailed pre-surgical evaluation, and opens the door to surgical cure for patients with drug-resistant, refractory epilepsy who have run out of medical options.
Neuro-Immunology & Demyelinating Diseases
- Conditions like multiple sclerosis, neuromyelitis optica, and autoimmune encephalitis require specialist expertise and access to the latest disease-modifying therapies.
- The neuro-immunology programme at SIMS provides both, in a supportive environment that understands the long-term nature of these conditions.
Movement Disorders & Functional Neurology
- Whether it is a Parkinson's disease, essential tremor, or dystonia, the movement disorders, SIMS offers personalised management through pharmacotherapy, botulinum toxin injections, and deep brain stimulation, helping patients maintain independence and quality of life for as long as possible.
Headache & Pain Management Clinic
- Chronic headaches and neuropathic pain can be severely disabling. SIMS' dedicated headache and pain clinic provides specialist evaluation and treatment options for migraine, cluster headache, trigeminal autonomic cephalalgias, and persistent neuropathic pain.
Neurocritical Care
- Complex brain and spine surgeries, as well as major neurological emergencies, necessitate close monitoring by specialists.
- The SIMS Neuro ICU has 8 dedicated beds and constant monitoring to ensure critical patients receive the necessary treatment.
- Our integrated model provides speedier diagnosis, treatment decisions, and coordinated care, ensuring patients receive appropriate interventions at the correct time.
