Sciatica Surgery: Types, Procedure, Risks and More
What is Sciatica Surgery?
Sciatica surgery is a surgical procedure performed to relieve pressure on the sciatic nerve, which extends from the lower back through the hips, buttocks, and legs. The surgery aims to remove the source of nerve compression, such as a herniated disc or bone spur, helping reduce pain, numbness, and weakness while improving mobility and quality of life.
Types of Sciatica Surgery
The type of surgery depends on the underlying cause of nerve compression.
Microdiscectomy
A minimally invasive procedure that removes the portion of a herniated disc pressing on the sciatic nerve.
Laminectomy
Removes a small part of the spinal bone (lamina) to create more space and relieve pressure on the nerve.
Foraminotomy
Widens the opening where the spinal nerve exits the spinal canal, reducing nerve compression.
Spinal Fusion
Performed in severe cases to stabilize the spine by permanently joining two or more vertebrae.
Symptoms of Sciatica
Common symptoms include:
- Pain radiating from the lower back to the buttock, thigh, and leg
- Numbness or tingling in the affected leg
- Weakness in the affected leg or foot
- Sharp pain while coughing, sneezing, or sitting for long periods
- Difficulty controlling bowel or bladder function (in severe cases)
When is Sciatica Surgery Needed?
Surgery may be recommended when:
- Non-surgical treatments fail to relieve symptoms.
- Severe or worsening weakness develops.
- Loss of bowel or bladder control occurs.
- Pain becomes severe and affects daily activities.
- MRI or CT scan confirms significant nerve compression.
Sciatica Surgery Procedure
Before Surgery
Before surgery, your doctor may recommend:
- Physical examination
- Medical history review
- MRI or CT scan
- Blood tests
- Pre-operative instructions, including fasting and medication adjustments
During Surgery
The procedure generally involves:
- Administration of general or spinal anaesthesia.
- A small incision near the affected spinal area.
- Removal of the structure compressing the sciatic nerve.
- Closure of the incision with sutures or staples.
After Surgery
Recovery usually includes:
- Pain management with prescribed medications
- Limited physical activity during healing
- Physical therapy and rehabilitation exercises
- Regular follow-up appointments
Risks of Sciatica Surgery
Like any surgical procedure, sciatica surgery has potential risks, including:
- Infection
- Bleeding
- Nerve damage
- Cerebrospinal fluid (CSF) leak
- Recurrence of symptoms
- Anaesthesia-related complications
Recovery After Surgery
Recovery varies depending on the type of surgery and the patient’s overall health. Following your doctor’s advice, attending physical therapy sessions, avoiding heavy lifting, and attending follow-up visits can help ensure a successful recovery.
Conclusion
Sciatica surgery can provide significant relief for patients with severe or persistent sciatic nerve pain that does not improve with conservative treatment. Understanding the different surgical options, potential risks, and recovery process helps patients make informed treatment decisions. Following the recommended rehabilitation plan is essential for achieving the best possible outcome.

Brain Tumor Surgery: Types, Procedure and Other Treatment Options
Consultant Neurosurgeon
Brain tumours, whether benign or malignant, pose a significant threat to an individual’s health and well-being. Advancements in surgical technology and techniques have made brain tumour surgery a life-saving procedure.
Types of Brain Tumor Surgery
Craniotomy
This is the most common type of brain tumour surgery. In this procedure, a portion of the patient’s skull is temporarily removed to access the tumour. The surgeon then carefully removes the tumour while trying to preserve as much healthy brain tissue as possible.
Minimally Invasive Brain Surgery
This approach involves using advanced imaging techniques and specialised instruments to access and remove the tumour through a small opening in the skull. It is often preferred for tumours located in deep or sensitive brain areas.
Signs and Symptoms of a Brain Tumour
- Persistent headaches
- Seizures
- Double vision, blurred vision, or peripheral vision loss
- Personality changes or mood swings
- Loss of balance or coordination
- Hearing problems or ringing in the ears
- Nausea and vomiting
- Speech difficulties
- Memory problems, difficulty concentrating, or confusion
Diagnosis of Brain Tumour
- Medical history and physical examination
- Blood tests
- MRI, CT scan, or PET scan
- Biopsy
- Lumbar puncture (spinal tap)
- Neurological examination
Brain Tumor Treatment
Surgery
The objective of brain tumour surgery is to remove as much of the tumour as possible while minimising damage to surrounding healthy brain tissue.
Brain Tumor Treatment Without Surgery
- Radiation Therapy
- Chemotherapy
- Targeted Therapy
Risks of Brain Tumor Surgery
- Bleeding in the brain
- Infection
- Blood clots
- Brain swelling
- Stroke
- Seizures
- Cerebrospinal fluid leakage
- Weakness, numbness, speech or vision problems
- Memory loss or confusion
- Functional impairments affecting movement or sensation
Prevention
- Maintain a balanced diet rich in fruits and vegetables
- Regular physical activity
- Avoid excessive exposure to ionising radiation
- Protect your head from injuries
- Avoid smoking and alcohol consumption
- Limit exposure to harmful chemicals and pollutants
- Discuss family history of brain tumours with your doctor
When to See a Doctor
If you experience persistent or worsening symptoms that may indicate a brain tumour, it is crucial to seek medical attention promptly. Early diagnosis and correct treatment can improve the chances of a successful outcome.
Conclusion
Brain tumour surgery has become safer and more effective with advancements in medical technology. Early recognition of symptoms and timely medical care play a vital role in achieving better treatment outcomes.

Silent Stroke: Warning Signs and Treatment
What is a Silent Stroke?
A silent stroke occurs when the blood supply to a part of the brain is suddenly interrupted, depriving brain tissue of oxygen and causing damage to brain cells. Unlike a regular stroke, a silent stroke usually does not produce obvious warning signs or symptoms, making it difficult to detect.
Although symptoms may not be noticeable, silent strokes can affect memory, thinking abilities, and increase the risk of a major stroke in the future.
Symptoms of Silent Stroke
Silent strokes may be associated with the following symptoms:
- Problems with memory and cognitive function
- Temporary loss of muscle control
- Balance problems
- Mood or personality changes
- Speech difficulties
- Loss of sensation, vision, or strength
- Fainting
What to Do When Someone Has a Silent Stroke?
If a silent stroke is suspected:
- Seek immediate medical attention.
- Consult a healthcare professional for evaluation.
- MRI or CT scans may be recommended for diagnosis.
- Follow the prescribed treatment plan.
- Manage risk factors such as high blood pressure, diabetes, and high cholesterol.
- Attend regular follow-up appointments.
When Should You Visit a Doctor?
Consult a doctor immediately if you notice any signs of a stroke or have risk factors such as:
- High blood pressure
- Irregular heartbeat
- Diabetes
- High cholesterol
- Previous history of stroke
Early diagnosis can help prevent serious complications.
Preventing Silent Strokes
The following lifestyle changes can reduce the risk of silent stroke:
- Control high blood pressure and diabetes.
- Maintain healthy cholesterol levels.
- Eat a heart-healthy diet.
- Exercise regularly.
- Maintain a healthy weight.
- Quit smoking and avoid excessive alcohol consumption.
- Have regular health check-ups.
Silent Stroke vs. Mini Stroke
| Silent Stroke | Mini Stroke (TIA) |
|---|---|
| Usually has no noticeable symptoms | Causes temporary stroke-like symptoms |
| May cause permanent brain damage | Usually does not cause permanent damage |
| Often detected through MRI or CT scan | Symptoms usually disappear within 24 hours |
| Increases the risk of future stroke | Considered a warning sign of future stroke |
Conclusion
A silent stroke may occur without noticeable symptoms, but it can still cause permanent brain damage and increase the risk of future strokes. Early diagnosis, proper treatment, and healthy lifestyle changes are essential for reducing stroke risk and protecting long-term brain health.
