Sphenopalatine Ganglion Block

Overview & Procedure 

The sphenopalatine ganglion is a bundle of nerves that is located in the midface behind the nasal passages and, if damaged or traumatized, can cause severe pain in the face and head. Recent research has highlighted the ability of alleviating headache and facial pain through a minimally invasive procedure known as a sphenopalatine ganglion block. 

During the procedure, the patient is positioned in a reclined or laying position with the head slightly elevated. Local anesthetic is delivered to the sphenopalatine ganglion through the nostril. There is typically only minimal discomfort during the procedure.  

After Care 

Immediately after the procedure, patients are sent to a separate room to recover. During this time, the patient’s vitals are monitored for any signs of an adverse reaction. Typically, patients resume full activity the next day. Soreness around the procedure site may be relieved by using ice and taking a mild analgesic. Pain relief from a Sphenopalatine Ganglion block typically lasts weeks to months and can be repeated. Complications are rare, but if patients notice any signs of an infection, rash, or fever, we strongly encourage them to come to Southwest Spine and Pain Center.
