Brain surgery has advanced more in the last thirty years than in the previous century. What was once considered inoperable is now routinely treated. Tumours in eloquent brain areas — controlling speech, movement, and memory — can be removed while the patient is awake. Navigation systems guide instruments through corridors only millimetres wide.
Prof. Giv Sharifi has practised through this transformation, performing complex brain surgery in Dubai and Tehran for over 25 years. The future of brain surgery is already here — and it means safer operations, better outcomes, and more patients who can return to the life they knew before diagnosis.
Revolutionary Advances in Brain Imaging
Modern brain surgery begins long before the first incision. High-resolution MRI reveals tumour boundaries, blood supply, and relationship to critical structures. Functional MRI (fMRI) maps language and motor areas. Diffusion tensor imaging (DTI) traces white-matter tracts that must be preserved during resection.
- 3D MRI reconstruction for surgical planning
- Functional MRI for language and motor mapping
- Tractography to visualise critical white-matter pathways
- Perfusion MRI and spectroscopy for tumour grading
- Intraoperative MRI to confirm complete tumour removal
These tools allow surgeons to plan the safest route to a lesion — avoiding eloquent cortex and major vessels — before entering the operating theatre.
Awake Brain Surgery (Awake Craniotomy)
Awake craniotomy is one of the most remarkable innovations in modern neurosurgery. For tumours near speech or movement areas, the patient is woken during the operation to test language, memory, and limb function in real time. The surgeon can map and protect essential brain areas while removing as much tumour as safely possible.
Despite its dramatic name, awake brain surgery is well tolerated by most patients with appropriate anaesthetic technique. It has become standard of care for gliomas and metastases in eloquent regions — dramatically reducing post-operative deficits compared with surgery under general anaesthesia alone.
Fluorescence-Guided Tumour Resection
5-ALA fluorescence guidance causes glioma tissue to glow under special blue light during surgery. This helps surgeons distinguish tumour from healthy brain, improving the extent of resection — a key factor in survival for high-grade glioma patients. Similar fluorescence techniques are advancing for meningioma and metastatic brain tumours.
Minimally Invasive & Keyhole Approaches
Not every brain operation requires a large craniotomy. Keyhole approaches use small bone openings guided by neuronavigation. Endoscopic surgery accesses ventricular tumours and colloid cysts through minimal corridors. Endoscopic transnasal surgery reaches pituitary and skull base lesions without facial incisions.
- Smaller scars and less post-operative pain
- Reduced brain retraction and oedema
- Shorter ICU and hospital stays
- Faster neurological recovery
- Suitable for deep-seated and skull base lesions
Robotics, AI & the Next Decade
Robotic instrument holders, AI-assisted surgical planning, and augmented reality overlays are entering mainstream neurosurgery. Molecular profiling of brain tumours enables personalised chemotherapy and immunotherapy alongside surgery. Laser interstitial thermal therapy (LITT) treats deep lesions through a small probe without open resection.
These innovations share a common goal: remove or treat the problem while preserving the person — their speech, personality, independence, and quality of life.
Brain Surgery in Dubai & Tehran
Patients in the UAE, Iran, and across the Gulf region can access advanced brain surgery without travelling to distant international centres. Prof. Sharifi provides consultation and surgery at City Walk, Dubai and Tavanir, Tehran — with medical tourism coordination for patients seeking specialist neurosurgical care in Iran.

When to Seek a Brain Surgery Consultation
Symptoms that warrant urgent neurosurgical review include new or worsening headaches, seizures, progressive weakness, speech difficulty, vision changes, or personality change. A brain MRI and specialist consultation can clarify the diagnosis and treatment options — often revealing that modern technique makes surgery safer than patients feared.
If you or a loved one has been diagnosed with a brain tumour, vascular malformation, or other intracranial condition, do not delay specialist review. Early intervention by an experienced brain surgeon can change the trajectory of the disease — and the life ahead.
