Neurosurgery has evolved over recent years, with advances in surgical planning and imaging supporting more precise approaches to brain surgery. Awake craniotomy is one such technique and may be considered in selected cases where conditions are located close to areas involved in speech, movement, and other important neurological functions.
At Precision Neurosurgery, our specialist at Mount Elizabeth Hospital performs awake craniotomy in Singapore following careful clinical assessment. This approach is supported by detailed preoperative planning, advanced imaging, and coordinated perioperative care, with treatment decisions tailored to each patient’s condition.
What is Awake Craniotomy?
An awake craniotomy is a form of brain surgery in which the patient is awake for part of the procedure. This approach may be used when a tumour, seizure focus, or vascular abnormality is located near regions of the brain responsible for important neurological functions.
Unlike conventional brain surgery, where patients remain fully asleep throughout the operation, awake brain surgery allows selected neurological functions to be assessed during surgery. The patient may be asked to perform simple speech or movement tasks while the surgeon operates. This helps identify and preserve areas of the brain involved in essential functions.
By observing the patient’s responses during the procedure, the neurosurgical team can better understand functional boundaries, which may help reduce the risk of neurological impairment during treatment.
When is Awake Brain Surgery Recommended?
Awake craniotomy in Singapore may be considered when a condition is located close to areas of the brain involved in language, movement, or sensory processing. It may be used in selected cases such as :
- Brain tumours located near functional brain regions
- Epilepsy surgery, particularly when seizure activity originates from areas related to speech or motor control
- Selected brain aneurysm management cases, depending on the aneurysm’s location and complexity
A neurosurgeon will evaluate each patient based on imaging findings, neurological status, and overall health to determine whether awake brain surgery is an appropriate option.
Step-by-Step: What Happens During an Awake Craniotomy
Awake craniotomy is carried out in several carefully planned stages, with attention to both surgical accuracy and patient comfort:
- Pre-surgical Planning: Detailed MRI scans and neuronavigation systems are used to map brain structures and identify areas associated with important neurological functions. This information helps the surgical team plan the most appropriate and safe surgical approach.
- During Surgery: The patient is initially kept comfortable with sedation and local anaesthesia. At a key stage of the procedure, the patient is gently awakened. The team may assess speech, movement, or responses to simple tasks while monitoring brain activity to guide the surgery.
- Pain and Comfort Management: Local anaesthesia and supportive measures are used to manage discomfort throughout the procedure. Continuous communication between the patient and the surgical team helps maintain comfort and safety during the awake phase.
This structured approach allows the surgical team to identify functional brain areas more clearly while addressing abnormal tissue, supporting precise and carefully guided treatment.
Expertise at Precision Neurosurgery
Awake brain surgery in Singapore is performed by neurosurgeons trained in brain mapping and modern microsurgical techniques. At Precision Neurosurgery, the procedure is led by Dr Teo Kejia, who manages a wide range of brain and spine conditions.
Dr Teo’s work includes complex brain tumour procedures, where he uses techniques such as awake surgery and functional mapping, particularly for tumours like gliomas and glioblastomas. His practice also covers neuro-oncology, skull base surgery, neurovascular conditions, and various spinal disorders. In addition, his care extends to intracerebral aneurysms, strokes, hydrocephalus, trigeminal neuralgia, and traumatic injuries.
Procedures are supported by modern imaging, microsurgical equipment, and intraoperative monitoring facilities, allowing careful evaluation and treatment planning.
How Awake Craniotomy Supports Surgical Planning
Awake craniotomy offers specific advantages for patients with brain tumours or lesions near areas responsible for speech, movement, or other essential neurological functions. By allowing real-time assessment during surgery, this approach supports careful decision-making when operating close to functionally important brain regions.
Potential benefits include:
- Improved identification of critical brain areas during the procedure
- Greater preservation of speech and motor function
- A more targeted surgical approach that may reduce unnecessary disruption to surrounding tissue
Throughout surgery, continuous neurological monitoring and patient interaction allow the surgical team to adjust techniques as needed.
Patient Journey and Recovery
Recovery following awake brain surgery varies depending on the underlying condition and the complexity of the procedure.
At Precision Neurosurgery, postoperative care focuses on neurological assessment, imaging review, and ongoing evaluation to support recovery and treatment planning.
Conclusion
Awake craniotomy represents an important development in modern neurosurgery, allowing treatment of complex brain conditions with greater functional awareness and precision. This carefully planned and closely monitored approach aims to support both surgical accuracy and neurological preservation.
