PURPOSE OF REVIEW: Sphenopalatine ganglion (SPG) block has been used by clinicians in the treatment of a variety of headache disorders, facial pain syndromes, and other facial neuralgias. The sensory and autonomic fibers that travel through the SPG provided the scientific rationale for symptoms associated with these head and neck syndromes. Yet, despite the elucidation of this pathogenic target, the optimal method to block its pain-producing properties has not been determined. Clinicians have developed various invasive and non-invasive techniques, each of which has shown variable rates of success...

The sphenopalatine ganglion (SPG) is a parasympathetic ganglion, located in the pterygopalatine fossa. The SPG block has been used for a long time for treating headaches of varying etiologies. For anesthesiologists, treating postdural puncture headaches (PDPH) has always been challenging. The epidural block patch (EBP) was the only option until researchers explored the role of the SPG block as a relatively simple and effective way to treat PDPH. Also, since the existing evidence proving the efficacy of the SPG block in PDPH is scarce, the block cannot be offered to all patients...

BACKGROUND AND OBJECTIVES: Postdural puncture headache (PDPH) is a common complication following subarachnoid blockade and its incidence varies with the size of the needle used and the needle design. Supportive therapy is the usual initial approach. Epidural blood patch (EBP) is the gold-standard when supportive therapy fails but has significant risks associated. Sphenopalatine ganglion block (SPGB) may be a safer alternative. CASE REPORT: We observed a 41 year-old female patient presenting with PDPH after a subarachnoid blockade a week before...

STUDY OBJECTIVE: To demonstrate a possible alternative treatment for postdural puncture headache (PDPH). DESIGN: Postdural puncture headache is a common complication associated with neuraxial anesthesia and unintentional dural puncture. Epidural blood patch (EBP) is the standard therapy for PDPH but has risks including pain, dural puncture, and infection. Transnasal sphenopalatine ganglion block (SPGB) has been successfully used to treat migraine, cluster headache, and trigeminal neuralgia...

UNLABELLED: Percutaneous radiofrequency ablation (RFA) of the sphenopalatine ganglion (SPG) has been shown to be an effective modality of treatment for patients with intractable chronic cluster headaches (CHs). While the use of fluoroscopy for RFA of the SPG is common, to our knowledge there are no documented cases of procedures using cone beam computed tomography (CBCT) for image guidance. We present a case report of a patient suffering from chronic intractable CH with complete long-lasting relief after RFA of the SPG using CBCT...

BACKGROUND: Sphenopalatine ganglion (SPG), an extracranial structure, is connected with the central nervous system (CNS) through sympathetic and parasympathetic nerves. We hypothesized that SPG block through sympathetic nerves anesthesia might decrease blood pressure (BP) in recently diagnosed and never treated middle-aged patients with essential hypertension. METHODS: We performed SBG block in 22 hypertensive patients (mean age 45±12years, 15 men). All patients have been subjected to 24hour ambulatory blood pressure monitoring a week prior the procedure as well as in a period of 21-30days after the SBG block in order to estimate differences in 24h average systolic (24h SBP) and diastolic blood pressure (24h DBP), daytime, nighttime, pre-awake and early morning SBP and DBP as well as BP load...

INTRODUCTION: The presence of the blood-brain barrier (BBB) in vertebrates is a major limitation to the delivery of therapeutic agents into brain tissue. Mesenchymal stem cell (MSC) infusion has been shown to reduce stroke volume and improve recovery, but the BBB limits cellular engraftment. Sphenopalatine ganglion (SPG) stimulation has been shown to transiently increase BBB permeability. A rodent model was designed to test the hypothesis that SPG stimulation enhances the effect of MSC infusion...

UNLABELLED: A cluster headache (CH) is an excruciating pain centered on the periorbital region and is accompanied by autonomic symptoms. Despite the best currently available medical therapy, many patients still suffer from these headaches. Some patients also experience CH with side shift of attacks, which makes treatment more difficult. In light of the pathophysiological mechanism of CH, the sphenopalatine ganglion (SPG) is a promising therapeutic target for its management. SPG ablation and non-ablation techniques have been the preferred treatment for CH in recent decades...

PURPOSE OF REVIEW: The study focuses on neural blocks with local anesthetics in postoperative and chronic pain. It is prompted by the recent publication of several systematic reviews and guidelines. RECENT FINDINGS: For postoperative pain, the current evidence supports infusions of local anesthetics at the surgical site, continuous peripheral nerve blocks, and neuraxial analgesia for major thoracic and abdominal procedures. Ultrasound guidance can improve the performance of the blocks and different patient outcomes, although the incidence of peripheral nerve damage is not decreased...

BACKGROUND: Hemicrania continua (HC) is a chronic headache disorder characterized by a continuous, strictly unilateral head pain accompanied by cranial autonomic symptoms, which completely responds to indomethacin; however, few alternative treatment options exist for the patients with this disorder who cannot tolerate indomethacin. Sphenopalatine ganglion (SPG) block has been used for the treatment of various headaches, with the strongest evidence for efficacy in cluster headache. CASE REPORT: A 52-year-old woman with a 7-year history of HC was evaluated in our clinic for management of her headaches after she had stopped using indomethacin due to a bleeding gastrointestinal ulcer...

This study was performed to present the outcomes of trigeminal neuropathy management with the application of neurolytic block of sphenopalatine ganglion. This type of procedure is used in cases where pain is not well controlled with medical treatment. Twenty patients were treated with sphenopalatine ganglion neurolysis after their response to pharmacological management was not satisfactory. Significant pain relief was experienced by all but one patient and they were able to reduce or stop their pain medication...

The sphenopalatine ganglion (SPG) has attracted the interest of practitioners treating head and face pain for over a century because of its anatomical connections and role in the trigemino-autonomic reflex. In this review, we discuss the anatomy of the SPG, as well as what is known about its role in the pathophysiology of headache disorders, including cluster headache and migraine. We then address various therapies that target the SPG, including intranasal medication delivery, new SPG blocking catheter devices, neurostimulation, chemical neurolysis, and ablation procedures...

Jean Schoenen
The interest for the sphenopalatine ganglion (SPG) in neurovascular headaches dates back to 1908 when Sluder presented his work on the role of the SPG in 'nasal headaches', which are now part of the trigeminal autonomic cephalalgias and cluster headache (ICHD-III-beta). Since then various interventions with blocking or lesional properties have targeted the SPG (transnasal injection of lidocaine and other agents, alcohol or steroid injections, radiofrequency lesions, or even ganglionectomy); success rates vary, but benefit is usually transient...

Persistent idiopathic facial pain can be extremely difficult and significantly challenging to manage for the patient and the clinician. Pharmacological treatment of these painful conditions is not always successful. It has been suggested that the autonomic reflex plays an important role in the pathophysiology of headaches and facial neuralgia. The key structure in the expression of cranial autonomic symptoms is the sphenopalatine ganglion (SPG), also known as the pterygopalatine ganglion. The role of the SPG in the pathophysiology of headaches and facial pain has become clearer in the past decade...

BACKGROUND: This study aims to determine if repetitive sphenopalatine ganglion (SPG) blockades with 0.5% bupivacaine delivered with the Tx360 device results in long-term improvement in chronic migraine (CM). The SPG is a small concentrated structure of neuronal tissue that resides within the pterygopalatine fossa in close proximity to the sphenopalatine foramen and is innervated by the maxillary division of the trigeminal nerve. In a previous article, these authors reported repetitive SPG blockades with 0...

REVIEW
Ian R Winship
Cerebral collaterals are vascular redundancies in the cerebral circulation that can partially maintain blood flow to ischemic tissue when primary conduits are blocked. After occlusion of a cerebral artery, anastomoses connecting the distal segments of the MCA with distal branches of the ACA and PCA (known as leptomeningeal or pial collaterals) allow for partially maintained blood flow in the ischemic penumbra and delay or prevent cell death. However, collateral circulation varies dramatically between individuals, and collateral extent is significant predictor of stroke severity and recanalization rate...

Headaches and facial pain can be extremely difficult to manage for the patient and the clinician. In the medical literature, it has been suggested that the autonomic reflex plays an important role in the pathophysiology of facial neuralgia. The sphenopalatine ganglion is the largest parasympathetic ganglion outside the cranium. It is an easy accessible target for pain management. The application of radiofrequency nerve ablation was described in the medical literature. In this case report, we describe a 54-year-old female...
