SPG Ganglion Block Background

Sphenopalatine Ganglion (SPG) Block in Patna

CLINICAL OVERVIEW

Reset Cranial Autonomic Pain Pathways

The Sphenopalatine Ganglion (SPG) (also called the Pterygopalatine Ganglion) is a major nerve junction located deep in the face behind the nasal cavity. It serves as the central switching hub for parasympathetic, sympathetic, and sensory nerve signals traveling to the head, eyes, temples, forehead, and cerebral blood vessels.

When the SPG becomes chronically hyperactive, it triggers severe neurogenic vasodilation and releases inflammatory neuropeptides, causing the excruciating throbbing of Chronic Migraines and the piercing, agonizing retro-orbital attacks of Cluster Headaches (often called "suicide headaches") accompanied by eye redness, tearing, and nasal congestion.

Dr. Shrutika Bhagat performs advanced SPG blocks using gentle transnasal micro-applicators or precision fluoroscopy-guided needle placement. By delivering targeted local numbing medications or applying Pulsed Radiofrequency (PRF) waves to the ganglion, the hyperactive pain loop is instantly interrupted—providing dramatic cessation of acute attacks and long-term reduction in headache frequency without opioid medication.

PATIENT SELECTION & INDICATIONS

Who is a Candidate for an SPG Block?

Indicated for patients suffering from refractory headache and facial pain disorders that fail standard oral medication.

Chronic Refractory Migraines

Severe throbbing one-sided headaches occurring ≥15 days per month with nausea, vomiting, photophobia, and sound sensitivity.

Cluster Headaches ("Suicide Headaches")

Excruciating, piercing pain concentrated behind one eye and temple, accompanied by eye redness, tearing, droopy eyelid, and nasal stuffiness.

Sluder's Neuralgia & Atypical Facial Pain

Deep aching, burning pain in the mid-face, upper jaw, palate, and root of the nose not explained by dental or sinus pathology.

Medication Overuse Headaches (MOH)

Rebound headaches caused by daily painkillers, triptans, or combination analgesics, successfully detoxified using SPG blocks.

Trigeminal Autonomic Cephalalgias (TACs)

Paroxysmal hemicrania and SUNCT/SUNA syndrome producing frequent sharp cranial autonomic pain bursts throughout the day.

Head & Neck Cancer Pain

Severe intractable pain from tongue, throat, nasopharyngeal, or sinus tumors, effectively alleviated with neurolytic SPG blocks.

HEAD-TO-HEAD EVIDENCE

SPG Ganglion Block vs. Heavy Daily Medications

Clinical Parameter SPG Ganglion Block & PRF Daily Painkillers & Triptan Pills
Speed of Onset 5 to 10 minutes (Direct autonomic reset) 45 to 90 minutes (Slow gastrointestinal absorption)
Rebound / MOH Risk Zero (Non-pharmacological nerve calming) High risk of daily Medication Overuse Headaches
Systemic Side Effects None (No gastric, liver, or kidney toxicity) Stomach ulcers, cardiac vasoconstriction, drowsiness
Duration of Benefit Weeks to months (12–24 months with PRF) 4 to 8 hours per pill
Autonomic Symptoms Directly stops eye tearing & nasal congestion Fails to resolve parasympathetic eye/nasal symptoms
SURGICAL WORKFLOW

How an SPG Block is Performed

01

Clinical Evaluation

Dr. Shrutika Bhagat evaluates headache frequency, unilateral triggers, and autonomic symptoms (tearing, rhinorrhea, eye redness).

02

Nasal Mucosal Anesthesia

A gentle anesthetic spray numbs the nasal passages to ensure complete comfort throughout the procedure.

03

Transnasal / C-Arm Navigation

A flexible micro-catheter or fluoroscopy-guided needle is placed accurately into the pterygopalatine fossa over the ganglion.

04

Targeted Medication Delivery

Long-acting local anesthetic and anti-inflammatory solution bathes the SPG, blocking parasympathetic headache outflow.

05

Optional Pulsed Radiofrequency

For chronic patients, 42°C pulsed radiofrequency electromagnetic waves are applied to reset long-term neural excitability.

06

Immediate Relief & Home

The patient rests for 15 minutes. Acute head pain dissolves rapidly, and the patient returns home with immediate symptom relief.

FREQUENTLY ASKED QUESTIONS

Common Questions on SPG Ganglion Blocks

Most patients experience significant pain reduction within 5 to 15 minutes of the procedure. Severe throbbing, retro-orbital eye pressure, nausea, and light sensitivity rapidly calm down as the parasympathetic pain loop is interrupted.
Transnasal SPG blocks do not use needles inside the nose. A soft, slender micro-catheter with a gentle numbing swab is guided smoothly through the nostril. You may feel mild tingling or a brief taste of bitter medication in the throat, but there is no sharp pain.
A diagnostic local anesthetic block provides relief for weeks to months and breaks intractable headache cycles. When combined with Pulsed Radiofrequency (PRF) neuromodulation, long-term remission of 12 to 24+ months is commonly achieved.
Yes. By resetting the central cranial autonomic pain circuit, patients experience a dramatic reduction in monthly headache frequency and intensity, allowing Dr. Shrutika Bhagat to taper and stop daily dependency on heavy painkillers and triptans.
The transnasal SPG procedure takes approximately 10 to 15 minutes. Patients rest in the clinic for 15–20 minutes and can immediately drive home and resume normal daily activities.
Please bring your Brain MRI / CT films, a record of previous headache medications and treatments tried, and a headache symptom log (if available) for an evaluation with Dr. Shrutika Bhagat.
