Rhizotomy

What Is a Rhizotomy?

A rhizotomy is a specialised neurosurgical procedure used to treat severe, long-lasting nerve pain or muscle spasticity that has not responded to other treatments. The procedure works by targeting specific nerve fibres that are responsible for sending pain or abnormal muscle signals to the brain. By carefully interrupting these signals, a rhizotomy can provide significant and lasting relief.

Conditions Treated with a Rhizotomy

Rhizotomy is most commonly used to treat:

• Chronic nerve pain, including facial pain such as trigeminal neuralgia

• Severe muscle stiffness or spasticity

• Pain caused by damaged or overactive nerves

• Certain spinal and nerve-related pain conditions

This procedure is only recommended when more conservative treatments such as medication, physiotherapy, or injections have not been effective.

How a Rhizotomy Works

During a rhizotomy, the neurosurgeon identifies the nerve fibres that are causing pain or abnormal muscle activity. These nerve fibres are then carefully disrupted using precise surgical or minimally invasive techniques. The goal is to block the unwanted nerve signals while preserving as much normal nerve function as possible.

The procedure is highly targeted and is designed to relieve symptoms without affecting surrounding healthy nerves.

What Happens During the Procedure

A rhizotomy is usually performed using advanced imaging and specialised instruments to ensure accuracy. The patient is carefully monitored throughout the procedure, and only the specific nerves responsible for the symptoms are treated. Depending on the condition being addressed, the procedure may be performed through a small incision or using needle-based techniques.

Benefits of Rhizotomy

Rhizotomy offers several important benefits, including:

• Significant reduction or elimination of chronic nerve pain

• Improved movement and muscle control in cases of spasticity

• Reduced need for long-term pain medication

• Improved quality of life and daily functioning

What to Expect Before the Procedure

Before a rhizotomy, patients undergo detailed neurological evaluation and imaging studies to identify the exact source of symptoms. Your neurosurgeon will explain the procedure, expected outcomes, and any potential risks so that you can make an informed decision.

Recovery After Rhizotomy

Most patients recover quickly after a rhizotomy. Some mild soreness or temporary numbness may occur, but these symptoms usually improve over time. Many patients notice pain relief soon after the procedure, with continued improvement in the following weeks.

Risks and Safety

As with all medical procedures, a rhizotomy carries some risk, including temporary numbness, weakness, or changes in sensation. However, the procedure is carefully planned and performed using advanced techniques to minimise risk and maximise benefit.

Personalised Neurosurgical Care

Rhizotomy is not a one-size-fits-all treatment. Dr Magumbeze carefully evaluates each patient to ensure this procedure is the most appropriate option. Treatment is always tailored to the individual, with a focus on safety, symptom relief, and long-term neurological health.
