Advanced Headache Interventions: Cranial Nerve Block, GON Block, SPG Block & Botox Explained
Headache and migraine disorders affect millions of people across India, often disrupting daily life, productivity, and emotional well-being. For many patients, conventional treatments like painkillers, preventive medicines, or lifestyle changes may not be enough. When headaches become chronic, severe, or resistant to medical therapy, advanced interventional headache treatments provide new hope.
As the only Interventional Headache Neurologist in Faridabad, Dr. (Prof.) Kunal Bahrani specializes in modern, minimally invasive procedures like:
✔ Multiple Cranial Nerve Block
✔ GON Block (Greater Occipital Nerve Block)
✔ SPG Block (Sphenopalatine Ganglion Block)
✔ Botox for Chronic Migraine
These interventions offer long-term relief, reduced headache frequency, and improved quality of life for patients suffering from chronic migraine, cluster headaches, neuralgia, and refractory headache disorders.
Why Are Advanced Headache Interventions Needed?
Headaches can become chronic due to:
- Overactive pain pathways
- Inflamed nerves
- Neck or occipital nerve compression
- Sinus or facial nerve irritation
- Hormonal changes
- Post-COVID neurological effects
- Long-standing migraine disorders
When oral medicines fail or cause side effects, nerve blocks and Botox therapy directly target the overactive nerves responsible for generating pain.
These procedures are:
✔ Quick
✔ Painless
✔ Safe
✔ Highly effective
✔ Performed in OPD
✔ Provide instant or progressive relief
- Multiple Cranial Nerve Block: A Breakthrough for Severe Headache & Facial Pain
A Cranial Nerve Block involves injecting a mild anesthetic or anti-inflammatory medication near specific nerves supplying the face, forehead, temples, or neck.
Conditions Treated:
- Chronic migraine
- Facial neuralgia
- Trigeminal neuralgia
- Cluster headache
- Post-traumatic headache
- Sinus-related headache
How It Works:
The block temporarily interrupts pain signals traveling from irritated or inflamed nerves to the brain. This “resets” the pain pathway and reduces nerve hypersensitivity.
Benefits:
- Immediate pain relief
- Reduction in headache frequency
- Long-lasting relief (weeks to months)
- Helps patients reduce painkiller dependence
- Minimally invasive and safe
- GON Block (Greater Occipital Nerve Block): Relief for Migraine & Neck-Related Headache
The Greater Occipital Nerve (GON) runs from the upper neck to the scalp. When irritated, it can trigger:
- Migraine
- Occipital neuralgia
- Cervicogenic headache
- Tension-type headaches
What Is a GON Block?
A mild anesthetic + steroid injection is given at the back of your head, near the occipital nerve.
Why GON Block Works:
It reduces inflammation and calms overactive pain fibers that trigger headache flare-ups.
Benefits:
- Quick pain reduction
- Helps chronic migraine patients
- Improves neck stiffness
- Reduced headache intensity and recurrence
- Suitable for patients who cannot tolerate oral migraine medicines
- SPG Block (Sphenopalatine Ganglion Block): A Minimally Invasive Nasal Procedure
The Sphenopalatine Ganglion (SPG) is a nerve bundle deep in the nasal cavity involved in facial pain, migraines, and cluster headaches.
What Is SPG Block?
A specialized catheter delivers medication through the nose to temporarily “turn off” pain signals.
Conditions Treated with SPG Block:
- Intractable migraine
- Cluster headache
- Sinus-related headache
- Trigeminal neuralgia
- Facial pain syndromes
Benefits of SPG Block:
- Non-surgical
- Needle-free (trans-nasal)
- Provides rapid relief
- Excellent for cluster headache patients
- Decreases autonomic symptoms (tearing, nasal congestion, facial flushing)
- Botox for Chronic Migraine: FDA-Approved, Proven Relief for Long-Term Sufferers
Botox (Botulinum toxin type A) is a globally recognized treatment for chronic migraine, defined as:
👉 15 or more headache days per month
👉 8 days with migraine symptoms
How Botox Helps:
Botox relaxes overactive muscles, blocks pain neurotransmitters, and reduces nerve hypersensitivity.
Treatment Areas:
- Forehead
- Temples
- Neck
- Back of head
- Shoulders
Benefits:
- Fewer headache days per month
- Reduced migraine attacks
- Improved daily functioning
- Long-term relief with consistent cycles
- Particularly effective for stress-triggered headaches
