Acoustic neuromas, rare benign tumors that develop on the vestibular nerve, and due to their location and complex symptoms becomes challenging for doctor to treat. However, with CyberKnife radiosurgery, treatment for these tumors has been significantly revolutionized. Dr. Aditya Gupta, Director of Neurosurgery and CyberKnife at Artemis Hospital, Gurugram, discusses how this advanced technology offers patients a safer, non-invasive option for managing acoustic neuromas.
What is Acoustic Neuroma?
An acoustic neuroma is a benign tumor that grows on the vestibulocochlear nerve, which is responsible for hearing and balance. Although acoustic neuromas are rare, with only 1 in 1 to 20 million people being diagnosed annually, they are more common in women than men.
This tumor can lead to following symptoms, which may develop over time:
- Vertigo
- Facial numbness and tingling
- Balance issues
- Facial weakness
- Changes in taste
- Difficulty swallowing
- Headaches
- Clumsiness
- Mental confusion
In some cases, sudden hearing loss may also occur. When left untreated, acoustic neuromas can cause further complications due to their pressure on surrounding nerves and brain structures.
Causes of Acoustic Neuroma
The exact cause of acoustic neuromas is unknown, though certain factors have been linked to their development:
- Hereditary conditions, such as neurofibromatosis type 2 (NF2), which runs in families.
- Continuous exposure to loud noise, which may increase the risk.
- Radiation exposure to the face and neck, often from past medical treatments.
The tumor itself develops from Schwann cells, which cover nerve fibers. When it forms on the vestibulocochlear nerve, it is also referred to as vestibular schwannoma.
Treatment of Acoustic Neuroma with CyberKnife
Until recently, treatment options for acoustic neuromas were often limited to surgery, which posed risks like nerve damage and hearing loss. However, with CyberKnife radiosurgery, patients now have access to a non-invasive, highly effective option. This cutting-edge technology uses focused, high-dose radiation delivered with remarkable precision, targeting the tumor without the need for traditional incisions.
According to a study published in the Sage Journal, approximately 2 out of 100,000 people aged 30 to 60 develop acoustic neuromas, making it a rare condition. The size of the tumor plays a critical role in determining the treatment approach:
- Small tumors (less than 1.5 cm) are ideal candidates for CyberKnife treatment.
- Medium tumors (1.5 cm to 2.5 cm) may also be treated with CyberKnife, depending on individual factors.
- Larger tumors (over 2.5 cm) generally require surgical intervention due to the potential risks they pose.
CyberKnife offers an effective treatment option for smaller tumors, providing patients with a minimally invasive procedure that requires no incisions and causes minimal side effects. It delivers radiation with pinpoint accuracy, ensuring surrounding healthy tissues are unaffected.
How CyberKnife Works
Treatment begins with a CT scan, which is used to create a detailed 3D image of the tumor. These images are uploaded to the CyberKnife Treatment Planning System, where a personalized treatment plan is developed. The system’s advanced robotics and tumor-tracking capabilities ensure that radiation is directed precisely at the tumor.
The procedure itself typically requires 1 to 3 sittings, with each session lasting no more than 40 minutes. No sedation is required, and the procedure is painless, offering a far more comfortable experience compared to traditional surgery.
The side effects of CyberKnife radiosurgery are generally minimal. Hearing preservation is achieved in 50-75% of patients, and the incidence of temporary facial numbness is low (around 2-3%). After treatment, the tumor is closely monitored to ensure it stops growing or begins to shrink over time.
Why Choose CyberKnife for Acoustic Neuroma?
CyberKnife radiosurgery offers a non-invasive, precise, and effective alternative to traditional surgery. This treatment option is particularly beneficial for patients with smaller tumors who want to avoid the risks associated with invasive surgery, such as hearing loss or nerve damage.
Additionally, the procedure requires no hospital stay, and most patients can return to their normal activities shortly after treatment.
Conclusion
Acoustic neuromas, though rare, can significantly impact a person's quality of life. The advent of CyberKnife radiosurgery has made treatment more effective and accessible than ever before.
