About Dr Teo Kejia
Dr Teo Kejia (also written as Dr Teo Ke Jia, and in Chinese as 张哿佳医生) is a Senior Consultant Neurosurgeon with over 15 years of clinical practice. He is the Director of Precision Neurosurgery, operating from Mount Elizabeth Medical Centre and Parkway East Medical Centre in Singapore, as part of the specialist network at Ascle Healthcare Group.
His practice centres on complex brain tumour surgery. He performs craniotomy and awake craniotomy using intraoperative brain mapping, an approach utilized in selected cases to help identify functionally critical areas of the brain during tumour resection. He completed subspecialty fellowship training in brain mapping and awake brain surgery under Professor Lorenzo Bello at Humanitas Research Hospital in Milan, Italy, and Professor Hugues Duffau at Gui De Chauliac Hospital in Montpellier, France. Prior to entering private practice, he served as a Senior Consultant in the Division of Neurosurgery at National University Hospital (NUH), where he established the hospital’s brain mapping and awake craniotomy service in 2017.
Alongside neuro-oncology (covering both brain and spinal tumours), Dr Teo manages neurovascular conditions, skull base disorders, traumatic head injuries, and degenerative spine conditions. He is a founding member of the Asian Low-Grade Glioma Network and has chaired several regional medical conferences on gliomas.
He is one of the specialists listed under Our Doctors.
Brain and Neuro-Oncological Conditions
-
Dr Teo’s primary clinical focus is the surgical management of brain tumours, including gliomas and glioblastomas. Where a tumour sits adjacent to functionally critical brain regions responsible for speech or motor control, intraoperative brain mapping and awake craniotomy may be employed in selected cases to monitor neurological function during surgical resection.
He also manages neurovascular conditions (such as intracerebral aneurysms and stroke), skull base lesions, hydrocephalus, traumatic head injuries, and functional neurosurgical conditions including trigeminal neuralgia and hemifacial spasm.
Spine and Nerve Conditions
-
Dr Teo manages spinal cord and vertebral tumours as part of his neuro-oncology practice, alongside degenerative spine conditions that cause neck and back pain. Minimally invasive spinal surgery is among his stated clinical interests. Whether a spinal condition is best managed conservatively or surgically depends on diagnostic imaging and individual clinical evaluation.
Conditions Evaluated and Managed
| Subspecialty Area | Conditions Evaluated |
|---|---|
| Neuro-Oncology | Glioma, glioblastoma, meningioma, brain metastases, spinal tumours |
| Neurovascular | Intracerebral aneurysm, ischaemic stroke, haemorrhagic stroke, arteriovenous malformation (AVM) |
| Skull Base & Functional | Skull base tumours, hydrocephalus, trigeminal neuralgia, hemifacial spasm |
| Trauma & Spine | Traumatic head injury, degenerative spine conditions (cervical and lumbar spondylosis, herniated discs) |
Surgical and Procedural Areas
Craniotomy & Awake Craniotomy
Brain tumour resection incorporating intraoperative brain mapping near functionally critical cortical regions.
Neuro-Oncological Surgery
Surgical resection of primary and secondary tumours of the brain and spinal cord.
Neurovascular Surgery
Microsurgical management of intracerebral aneurysms and vascular anomalies.
Skull Base Surgery
Surgical approaches to complex deep-seated skull base lesions.
Spinal Surgery
Minimally invasive and open surgical management for degenerative spine disorders and spinal tumours.
Emergency Neurosurgery
Craniectomy, burr hole placement, and drainage for intracranial haemorrhage, traumatic brain injury, or cerebral abscess.
Stereotactic Neurosurgery
Computer-guided stereotactic procedures and image-guided neurosurgical navigation.
Not every neurological or spinal condition requires surgical intervention. Depending on the diagnosis, management may involve conservative non-surgical approaches or surgical options, which are discussed during consultation.

Frequently Asked
Questions
Is Dr Teo Kejia a Brain Surgeon or a Spine Surgeon?
He is a neurosurgeon, and neurosurgery covers both. His stated primary focus is complex brain tumour surgery and neuro-oncology. He also manages spinal tumours as part of that work, treats degenerative spine conditions causing neck and back pain, and lists minimally invasive spinal surgery among his clinical interests.
What Is Awake Craniotomy, and When Does Dr Teo Kejia Use It?
Awake craniotomy is brain surgery in which the patient is awake for part of the operation, so that speech and movement can be tested while the surgeon works. Dr Teo uses it in selected cases where a tumour lies close to areas of the brain responsible for those functions, alongside brain mapping. It is not suitable for every patient or every tumour, and suitability is assessed individually. Dr Teo trained in this technique under Professor Lorenzo Bello in Milan and Professor Hugues Duffau in Montpellier, and established the awake craniotomy service at National University Hospital in 2017.
Which Hospitals Does Dr Teo Kejia Operate At?
He is attached to Mount Elizabeth Hospital and Parkway East Hospital in Singapore, and consults at Precision Neurosurgery within their medical centres. If an operation is recommended, it would take place at one of these Singapore hospitals. He does not operate at any hospital in the Philippines.
Does Dr Teo Kejia Hold Consultations in the Philippines?
No. His clinics are in Singapore and all consultations take place there. Patients based in the Philippines can send an enquiry and speak with the International Patient Liaison Centre before making any travel arrangements.
Can I Request a Second Opinion from Dr Teo Kejia?
Yes. A second opinion is a form of specialist consultation, and it takes place in Singapore. Send an enquiry describing your diagnosis and any treatment you are already receiving, and the International Patient Liaison Centre will confirm the next step and what information is needed.
Can Dr Teo Kejia See Patients Who Have Already Begun Treatment Elsewhere?
Yes. The International Patient Liaison Centre supports patients moving from an existing care arrangement, including medical triage, referral facilitation and coordination of appointments.
What Should I Prepare Before a Consultation with Dr Teo Kejia?
Have available any imaging and scan reports, biopsy or pathology results, letters from doctors already involved in your care, and a list of your current medications. Please do not attach medical records or scans to the online enquiry form. The team will advise how to share them securely once your enquiry has been received.
