What does sphenopalatine ganglion do?
The Sphenopalatine Ganglion (SPG) is a group of nerve cells that is linked to the trigeminal nerve, the main nerve involved in headache. The SPG, located behind the nose, carries information about sensation, including pain, and also plays a role in autonomic functions, such as tearing and nasal congestion.
How is sphenopalatine ganglion block done?
SPG blocks have been achieved with various techniques, including the use of lidocaine-soaked cotton tip applicator through the nose, transorally, transnasal endoscopic, infratemporal approach, and more recently using various noninvasive transnasal devices to inject anesthetics into the SPG [19].

What is sphenopalatine ganglion block used for?
Clinical Significance The sphenopalatine ganglion block is used for a variety of headache and facial pain syndromes and has variable efficacy depending on the disease process treated. Significant reduction in pain is meaningful when followed by an increase in functional capacity, reduction in health care use, and/or reduction in opioid use.
What are the contraindications to sphenopalatine ganglion block?

The effectiveness of neurolytic block of sphenopalatine ganglion using zygomatic approach for the management of trigeminal neuropathy. Neurol Neurochir Pol. 2015; 49 (6):389–394.
What does the sphenopalatine ganglion innervate?
The sphenopalatine ganglion is a parasympathetic ganglion of the facial nerve. Postsynaptic fibers leave the ganglion and distribute with branches of the maxillary division of the trigeminal nerve. These fibers provide parasympathetic innervation to the lacrimal and mucosal glands of the nasal fossa, palate, and pharynx.
